Description

DESCRIPTION OXADIAZON FOR REMEDY OF PHOTOXICITY PROBLEM IN RICE THE SAFE FORMULATION OF ITS MOLECULE AND METHOD OF APPLICATION IMPROVEMENT TECHNICAL FIELD Rice is the main food source of 40% of the world population, and it contains calories of approximately 2.7 billion people. It is a basic food item that meets 80% of its needs. Widespread in tropical and temperate regions 90% of the paddy that is cultivated is produced and consumed by Asian countries.

Paddy cultivation in the world is carried out in five cultivation systems according to the water regime. These systems Considering the cultivation area, it can be seen with irrigation, rain, deep water, dirt and floating paddy. is bred.

In general, the paddy production system is made with continuous irrigation, and in this method, paddy, field grown under water. From sowing to harvest 20 days, the field surface is watered. is covered. The water height is gradually increased depending on the development of the plants and Inaksiinum is kept around 15 cm during the developmental period.

The cultivation methods used in the irrigated paddy production system in the world depending on its ecological and social status. These are water-spread sowing (hand, fertilizer, scatterers and plane), dry planting with seeder, back planting and seedling (hand and seedling) is applied as Rice is generally grown in flooded plots (pans). Rice cultivation is either dry or It takes place in the form of scattering the seed into the water. This planting type difference is regional. habits, climatological conditions, availability or absence of sufficient water, and It differs due to many factors such as geographical conditions.

The most important part of paddy cultivation, which is of great importance as a food item all over the world, The problem is that of weed control. In paddy fields, weeds give great yield Beyond the loss, it even causes the producer to leave the planted area. also foreign weeds are susceptible to harmful organisms, for example Scirpophaga incertulas Cnaphaloeroeis inedinalis, hosts. Labor and economic resources to be spent in these areas with high weed density Since the price cannot be met with the paddy to be purchased after the harvest, these areas are either completely abandoned. or paddy is removed and another crop is planted. This new crop planting is the ideal planting season. It is a process other than that and requires more labor and more cost.

Before the discovery of weed pesticides (herbicides), weeds in the rice were physically removed by hand. was being destroyed. Insufficient labor in this technique, difficulty in working in flooded parcels. this again As a result of long-term work in the fields, many serious problems, especially rheumatism, Weed problem agriculture that cannot be fully controlled due to health problems and other difficulties prompted experts in the industry to research. As a result of these studies, herbicides has been discovered. The formation of paddy cultivation areas in flooded parcels causes intense weed emergence. causing it to happen. This intense weed attack is resistant to herbicides in a very short time. causes its development. Therefore, it is a herbicide with a constantly different mechanism of action. The search continues.

The main problem in weed control is the constant use of the same group of herbicides. as the use of yellow for years. This is the same application method and the same use without rotation. When the application period is added, resistance becomes inevitable. almost today The rice weed problem all over the world has reached an unsolvable point due to its resistance.

Today, the world rice market and the world rice market, as new application method and new herbicide cannot be developed. therefore, the rice food requirement is under threat. The invention uses a different method to eliminate this threat. It is a new formulation and a new method developed with the herbicide molecule oxadiazon.

The invention is a well-known but effective tool for weed control in paddy fields in the agricultural industry. Oxadiazon, which cannot be used in paddy fields due to phytotoxicity and accumulation in the soil of this molecule with the capsule suspension formulation technique of the chemical in the previous art. It aims to eliminate the problems seen in its use and to be used in the relevant industry.

With the invention, a capsule suspension formulation was developed from the oxadiazon molecule. This new form of herbicide active ingredient is used for weed control in paddy fields. tried, the high rice paddy seen in prior art formulations of the molecule in question It was observed that phytotoxicity was not in the formula subject to the invention, and also in weed control. achieved surprisingly high efficacy at lower doses.

KNOWN TECHNIQUE Oxadiazon is a chlorotil inhibitor herbicide, its chemical name is 5-tert-butyl-3-(2,4-dichloro-5- isopropoxyphenyl)-1,3,4-oxadiazol-2(3H)-0ne Oxadiazone is a moderately persistent herbicide with a half-life of 3-6 months. This herbicide soil It is strongly adsorbed and adsorbed to its colloids and is easily degraded. is not. Oxadiazone is not considered volatile.

Oxadiazon known formulation types (emulsion concentrate (EC), Water-Soluble Powder (WP), Granular (G) and other solid or liquid formulations ”except capsule formulation) Control of many weeds in areas cultivated with many agricultural products other than paddy used. In the previous art, oxadiazon is mostly used in grass fields, onions, cloves and many other agricultural products. used in production.

Oxadiazon is a herbicide that is more effective on seeds. The oxadiazon capsule formulation which is the subject of the invention Solid or liquid formulations other than has started, the application of active substances in the known art, especially in oxadiazon EC formulations As soon as it reaches its field, it is completely free. The free state of this molecule and Considering its persistence in the soil, the product is suitable for paddy weed control. will appear not. In other words, the effect of the free molecule that lasts for months lasts for months. attack means dose and this attack dose damages the rice plant as much as the weed, Therefore, unless the rice producers remain completely unsolved, the classical formulation of these products They don't use types. One of the previous techniques is the use of oxadiazon EC formulation type for weed control in rice. is to be used. In the applications made with this formulation type, it cannot be tolerated in paddy. phytotoxicity has been observed. It is formed by the application of the technique known by the inventors. Oxadiazon herbicide active ingredient for removal of heavy phytotoxicity and seed loss Numerous studies have been conducted on new formula techniques and different application methods. This As a result of the researches, the capsule suspension of the herbicide in question was used in the rice production industry. It has been discovered that it can be used in weed control. In the previous art, formulations other than capsule suspension were tried, germination failed in rice. faced with the problem. To eliminate this problem, in the prior art, oxadiazon After its use, the paddy area to be planted is washed at least 2 times. This procedure both costs It also increases the success rate of weed control. Because a wash On the one hand, while increasing the weed emergence, on the other hand, due to the washing of oxadiazon7, weed lowers the effective dose. In addition, the period between soil preparation and planting is due to various reasons. therefore it cannot be kept long. This period varies between 1-3 days. Because the paddy producer In this period, which is a very busy period for agriculture, meteorological conditions are often too much for the farmer. time is unknown. Therefore, other classical formulations other than Oxadizazone CS formulations The use of formulas in industry is not possible except in mandatory cases.

The known technique is the free-form oxadiazone topsoil after application of Oxadiazone EC. It is strongly held by colloids. found in the upper soil layers Oxadiazon comes into contact with rice seeds with rice planting. to the topsoil Oxadiazon, which is strongly attached, is completely free. Rice with October It comes into direct contact with the seeds and this contact has an attack dose effect. buddha paddy seed it loses its germination power and therefore causes the rice not to germinate. In the previous art, FOB, AuXin hormones, ALS effect in Turkey and in many countries of the world. Herbicide active substances with contact mechanism and contact effect were used. To these herbicides resistance has developed in many parts of the world and now these herbicides are resistant to Cyperus spp. Echinochloa spp, and Alisina spp. It cannot control weeds such as resistance management For this purpose, herbologists in many universities around the world are still using new solution tools or new working on methods. However, until now, neither a new molecule nor a new method has been found. not developed. The unresolved weed problem causes a yield loss of 3% to 45% in paddy. causes. In the prior art, Cyperus spp, Echinochloa spp, Digitaria saiiguinalis (L.)Scop and Diplachiie spp. in the control of weeds such as ALS group, bensulfuron methyl, penoxulam.

Bispiripak Na+ and other active substances are used. Application period of these active substances Although it varies according to herbicides, the application period is usually 2-3 to 6-8 days after emergence. It is the time period when it is leafy. Paddy is in water during these periods, and the application is very difficult and costly. from the air The problem is growing as the applications are also banned due to environmental sensitivity. This Wheeled tools are used in the field to spray the paddy in it and the cultivated plant is Great damage occurs due to chewing. These problems are eliminated with the invention.

In the other prior art, Cyperus spp, Echinochloa spp, Digitaria sanguinalis (L.)Seop and In the control of Diplachne fusca weeds from the FOB group, cyhalofob butyl, fenoxaprop-P- ethyl and other herbicide active substances with the same mechanism of action were used.

The application period of these active substances is also when the paddy has 4-8 leaves after emergence. language.

After 5-7 years of use against the herbicides mentioned in the previous art examples above resistance develops. The newest of these known herbicide molecules is more than 20 years old. are used, so the resistance problem is now maximized due to long-term use. has reached. This weed resistance is used for weed control in rice almost all over the world. It has become a big problem for him. By increasing the dose of the herbicides in question 4-5 times, Despite its application, the resistance cannot be prevented. In the previous art, it has a new mechanism of action apart from the above-mentioned mechanism of action. molecules were investigated, as a result of this research, oxadia20n was used with a new effect. gone. The results obtained in the experiments were recorded at each location. All The results are parallel to each other, and FOB, ALS, auxin in weed control with the use of oxadiazon Better results were obtained compared to hormones and contact herbicides. In these experiments, In addition to weed control, the effect on rice fouling was also evaluated. In the previous art, as a result of the applications made, in the cultivation areas where oxadiazon is used. Oxadiazon Emulsion Concentrate (EC) formulation type caused great damage to rice, tolerated Unexpected phytotoxicity results were encountered. In the previous technique, at least 2 times after the application in order to prevent phytotoxicity in the rice. Although soil washing has been done, the death of paddy seeds is at an intolerable level. is watching. In the previous technique, after at least 2 washes after applying the oxadiazon EC form, the long paddy cultivation was tried to be delayed for a while, in this case, it prevented weed emergence. could not be. Both time and seasonal conditions are not always suitable for waiting. Like, loss of effective dose due to exposure of oxadiazon to direct sunlight in the soil. was also recorded in the test results. Effective dose with both washing and waiting falls significantly and cannot control the weed emergence that will come later. In the previous technique, the amount of oxadiazon lost with washing and waiting is below the effective dose. It was tried to keep the initial dose high so that it would not decrease, and in this case, it was both economical and economical. It has been faced with problems that cause both loss and unnecessary ecological pollution. Beginning Keeping the dose high can prevent seed germination in rice. High dose In case the washing and waiting processes cannot be done technically correctly, oxadiazon can be found in the soil. will remain and cause paddy germination to stop completely. In the prior art, keeping the initial dose high will reduce non-target areas with washings. chemically contaminated. Especially EC formulation (emulsion concentrate) The release of petroleum-derived solvents and emulsifiers in the form to the nature causes ecological pollution. does not cause. This chemical contamination is eliminated by the invention. Because the invention formula The capsule formulation is water-based and safer against nature compared to previous formulations. It is mentioned above that at least 2 washings should be done in the previous technique (in the use of Oxadiazon EC). specified. In regions with water insufficiency, the necessary water for these washings cannot be supplied, In this case, paddy cultivation is abandoned or other solutions are sought. In cases where soil washing is done correctly in the use of Oxadiazon EC, which is the previous technique. Even in some parts of the fields, there is an accumulation of herbicides and no rice is produced from these parts. cannot be received.

In other prior art, washing is usually done 4 days after the herbicide has been applied. After washing, it is waited for 6 days and sowing is done. In the previous art, sometimes with the 4th day, this Oxadiazone in the soil due to washing in the waiting period of the planting time after the EC is decreasing or completely ending. This result is the new weed in the 6-day time frame. causes the seeds to germinate. Also, only starter weed seeds weed seeds that will emerge later cannot be controlled. Another In other words, the effect is short-lived.

In the known Oxadiazone EC application technique, the above causes (washing, waiting...) In addition, the formulation performance is also insufficient. Oxadiazon EC formulation and present invention The comparative trial with the formulation of It is presented to your attention in the section where it is explained in detail. According to the results obtained, the invention is the most showed higher performance at less than 20% lower dose.

OBJECTIVE OF THE INVENTION Considering the known technique described above, the oxadiazone molecule in rice new formulations are needed for its use in the fight against weeds in the production of is seen. In this direction, the inventors can reduce the weeds growing in the paddy fields. They aim to develop an oxadiazone formulation to control

In one aspect, the inventors are in the form of a capsule suspension (CS) containing the active ingredient oxadiazon. formulations, which will not cause titotoxicity and will not drift in the soil, different plant To develop a method that will ensure that it is applied in a way that does not harm the species. they are for the purpose.

The inventors also have the ownership of herbicides used to control weeds in rice production. aims to develop a formula that overcomes the disadvantages of find in this context The owners of the oxadiazon active substance, which has not had a resistance problem until now, before planting. A formula on the use and control of weeds at the seed stage by developing effective weed control, in terms of environment, efficiency, cost and labor They aim to develop a product that saves money. Formulations according to the present invention usually petroleum-based, released out of paddy pans and mixed with underground and surface waters. It prevents the use of solvents and emulsifiers.

To the surprise of the inventors, the Oxadiazon capsule suspension is detailed below. With its form, it is seen that weeds are taken under control in paddy production and that paddy paddy that the seed was not damaged during the application and the yield of the cultivated area increased. they have found.

BRIEF SUMMARY OF THE INVENTION The problem that the invention aims to solve is that oxadiazone cannot be used due to thitotoxicity.

This problem is caused by the CS formulation of oxadiazon active ingredient in weed control in rice. solved by using Weed with the use of Oxadiazon CS formulation A higher effect was obtained at a lower dose compared to the known formulations in the control In addition, the problem of Itotoxicity occurring in rice with known formulations is eliminated. has been removed.

The dosage and forine of the active substance are not limited to those listed here, but other solid or liquid may be in formulations.

The invention is based on the capsule suspension formulation of Oxadiazon as well as other water-based single and multiple includes formulations.

The invention is related to the use of the oxadiazon molecule in Iitotoxin or other efficacy problems. It can also be used in agriculture or non-agricultural areas. Agriculture such as different agricultural plants and grass fields Its use in weed control in outdoor areas is also within the scope of the invention.

With the invention, weed especially Cyperus spp. can control some Echinochloa species at a rate of >90%. In the areas where the invention is applied, higher efficiency can be achieved compared to other areas because it is being done.

In their studies, the inventors used the method of the invention in capsule suspension form. It was found that the use of oxadiazon unexpectedly increased its efficiency, and in this way, paddy cultivation It is a low-cost, easy-to-apply and high-yielding product in the fight against weeds in They saw that it was obtained in a new method with the formulation. Therefore, the invention is another In terms of application of Oxadiazon molecule to paddy production areas, oxadiazon capsule Relating to a method of administering a suspension formulation, the said method; l. Application of Oxadiazon CS formulation to the soil before rice cultivation 2. Watering the area to be planted at least 24 hours after the formulation application and 3. At least 48 hours after the application of the foniulation, by keeping them in water in sacks beforehand. of rice seeds that have begun to germinate (exploded or otherwise called awakened) It consists of the steps of planting in the prepared area.

The expression "started to germinate" used within the scope of the present invention was also detonated. or awakened seed meanings.

Oxadiazon CS was first applied to the cultivation area prepared by the inventors in their studies. With the application of its formulation, it can increase the germination power of weed seeds by >90%. They found that it was lost and there was an astonishing effectiveness in weed control. This efficacy at least 20% lower than oxadiazon emulsion concentrate formulation has been obtained. At least 24 hours after Oxadiazon CS application Preferably after 96 hours, water is released to the field and it is ready for germination, preferably 144 hours after this process. they threw the rice seeds on the water surface. Thus, the semi-germinated rice tolium in sacks Unaffected by Oxadiazon CS. (However, the same process is used for oxadiazon EC (emulsion concentrate) It has been observed that paddy seeds lose their germination power when it is made with its formulation.)

The inventors have made various experiments with the method described in detail above. made In one of the studies, 20% capsule suspension of Oxadiazon active substance, which is the subject of the invention, It provided weed control at the level of >90% at doses.

The inventors know that the formulation according to the present invention is available in the state of the art. Experiments to show that it has superior properties than formulations has done. Below are inventive and prior art formulations and application methods. There are common results of the experiments carried out. The said experiments; 1. Ondokuzmayis University, Department of Plant Protection Prof. Dr. Khosrow MENNAN and his team by Osmancik-Çorum-Turkey, Ipsala-Edirne-Turkey in May-September 2014 has also been carried out. 2. By Expert Agronomist Mesut Atalay, Deniz serdar Özçelik and Volkan Öztürk in May- Between September 2013-2014, Bafra Samsun-Turkey. Boyabat-Sinop-Turkey. Dip Balikesir-Turkey, Çavusköy, Biga Balikesir-Turkey, Uzunköprü-Edirne in Turkey has been carried out. 3. The results in the table are taken according to the arithmetic averages, each test result is less than 5% from the other. did not show much deviation.

Herbicide of the Invention and Known Art E. E. cus-galli C. A. plantago- oryzodies difformis aquatica 5Oxadiazon EC 60 a.i/da (Known Rice Rice Outlet Rice Rice Outlet Technical) SELECTIVITY DOSE was not output. it didn't come out. It didn't happen. It didn't happen.

The invention was found to be successful by exceeding the 90% threshold at a dose of 30 g a.i/da. Washing after application etc. no action has been taken. One negative result compared to control groups in germination makes me not observed.

In addition, at least one harmful effect of the inventive oxadiazon formulation starting from 20 g a.i/da dose. It is seen that it gives better results than the formulation of the known technique.

The invention shows a mild, at a dose of selectivity for its effects on phytitoxicity and rice germination. Phytotoxicity was observed and the phytotoxicity ceased within 7 days. Herbicide at the end of the 30th day No difference was observed between the unapplied rice field and the invention selectivity dose field rice.

Soil washing was not carried out after the application of the selectivity dose. Prior art oxadiazon EC herbicide, the effective dose of the invention is no weed at a dose of 30 g a.i/da. The nerve value was not effective over 90%. Soil one (1) time after application has been washed. In addition, at a dose of oxadiazon EC 30 g ai /da, the selectivity of the invention showed a higher phytotoxicity than rice dose (60 g a.i/da). Control during harvest group, the rice in the fields where the known technique (oxadiazon EC 30 g ai/da) herbicide is applied. sizes differed. Since there is no effective dose, the application causes loss of efficiency. It is not considered whether it was created. Prior art oxadiazon EC herbicide at a dose of 375 g a.i/da limited success in some weeds has shown. In this application, soil washing was done two (2) times. 15 days improvement in paddy retardation was observed and 13% yield loss occurred during the harvest period. For prior art oxadiazon EC, the invention selectivity dose of 60 g a.i/da is in the previous technique. Evaluated as the selectivity dose, two (2) times soil washing in the applied application. although there was no paddy output. Rice output in high dose applications possible by the manufacturer It will not be possible to use Oxadiazon EC application for weed control in rice. It has been found that it is not suitable. An effective dose of weed (37.5 g a.i/da) of the formulation according to the previous technique was applied. When the observation was made in the field after 30 days, it was observed that the germination stopped.
