The present invention has the following advantages:
1, the bactericidal action of this gadolinium nitrate berberine complex pesticides sterilizing emulsion agent is strong, and toxicity is low, to the person poultry safety, has alleviated environmental pollution, also has sterilization wide spectrum, quick-acting and characteristics that lasting effect is good, is comparatively ideal pesticide kind of control vegetables germ.
2, this preparation method technology is simple, easy to operate.
3, easy to use, dissolubility improves.The gadolinium nitrate berberine complex is the yellow floccule that is insoluble in water.With the suspension emulsion finished product that this complex is mixed with, water-fast gadolinium nitrate berberine complex is scattered in the water.Can be made into the aqueous solution during use and carry out face of land spraying or directed the irrigation, make it directly act on corps diseases position, instant effect.
According to the assay method of the agricultural chemicals stability of emulsion of national standard (GB/T1603-2001) regulation, gadolinium nitrate berberine complex emulsion is measured.Measurement result complies with the national standard requirements, and emulsion stability is better.The measurement result of emulsion physicochemical property is shown in Table 1; Emulsion heat storage stability measurement result is shown in Table 2.
The measurement result of table 1 emulsion physicochemical property
Table 2 emulsion heat storage stability
Bacteriostasis, toxicity test and the field experiment of gadolinium nitrate berberine complex pesticides sterilizing emulsion agent are described in detail in detail respectively below:
One, bacteriostasis
The test germ is selected tomato bacterial canker germ, black rot of carrot bacterium, sclerotium blight of sunflower bacterium and muskmelon angular leaf spot fungus.
Method of testing:
1, the mensuration of antibacterial circle diameter
From 4 ℃ of refrigerators, take out the go down to posterity bacterial strain of preservation of inclined-plane, place 26 ℃ of constant incubators to activate 24h, add the 5.0mL stroke-physiological saline solution in the bacterial strain after activation, make bacteria suspension.Add each bacteria suspension of 0.2mL in corresponding sterile petri dish with aseptic dropper respectively, will melt and be cooled to about 20mL in 45 ℃-50 ℃ the above-mentioned culture dish of aseptic potato culture impouring, mixing cools off rapidly, makes to contain the bacterium flat board.
The gadolinium nitrate berberine complex is mixed with the solution that concentration is 10mg/mL.Be stained with behind the alcohol by flame calcination sterilization with tweezers, three times repeatedly, the diameter that tweezer speckles with bacteriostatic agent to be measured is the aseptic filter paper sheet of 9mm, is affixed on to contain the bacterium planar surface, and the required distance between each scraps of paper evenly equates.Place 26 ℃ of constant incubators to cultivate 24h in culture dish, observe filter paper and have or not inhibition zone on every side, and measure its diameter.Each medicine is provided with three parallel laboratory tests, and experimental result is got its mean value.Measurement result is shown in Table 3.
Table 3 bacteriostatic activity (antibacterial circle diameter/mm)
2, the mensuration of minimum inhibitory concentration
In the triangular flask of four 250mL, add the potato liquid nutrient medium of 100mL, under the 0.1MPa, 121.3 ℃, high pressure steam sterilization 20 minutes.After cooling, in the sterile working platform,, insert in the liquid nutrient medium, tie mouth with tampon with transfer needle picking one ring from the inclined-plane bacterium colony of four kinds of bacterium respectively.Under 26 ℃, the condition of 175r/min, the shaking table overnight incubation obtains bacteria suspension.
The mensuration of minimum inhibitory concentration adopts the solid culture medium dilution method.In culture dish, add bacteria suspension 0.1mL earlier, the medicine to be measured that in an aseptic conical flask, adds metering, the N that adds 1mL then, dinethylformamide is as solvent, the sterilization solid potato culture medium that adds certain calorimetric again obtains a medicine flask of concentration maximum as dilution, is carrying out doubling dilution with liquid nutrient medium then, obtain the drug solution to be measured of 4 kinds of variable concentrations successively, at last the medicine in above-mentioned four flasks is poured into culture dish, shaken up.Place 26 ℃ of constant incubators to cultivate 24h, write down the growing state of bacterial strain in each culture dish, determine the minimum inhibitory concentration (MIC) of various medicines.Experimental result sees Table 4.Experimental result shows that the gadolinium nitrate berberine complex is 0.0005g/ml to the minimum inhibitory concentration of muskmelon angular leaf spot fungus and black rot of carrot bacterium; Minimum inhibitory concentration to sclerotium blight of sunflower bacterium and tomato bacterial canker germ is 0.000125g/ml.According to the measurement result of antibacterial circle diameter and minimum inhibitory concentration, illustrated that the gadolinium nitrate berberine complex is stronger to the bactericidal action of tomato bacterial canker germ, black rot of carrot bacterium, sclerotium blight of sunflower bacterium and muskmelon angular leaf spot fungus.
The measurement result of table 4 minimum inhibitory concentration (g/ml)
Two, the toxicity test of control vegetables germ agricultural chemicals
1, acute oral toxicity test
With small white mouse (elder brother white mouse, SCXK (illiteracy) 2002-0001, cleaning level) as experimental subjects.According to operating about the regulation of acute oral toxicity test in the national standard Gsl5670-1995 agriculture chemical registration toxicology test method.
In acute oral toxicity experiment, at first select dosage to reach the gadolinium nitrate berberine complex of 5000mg/kg body weight, in the whole experiment observation period, small white mouse does not have any intoxicating phenomenon and occurs, all physical signs, health are acted normally, and growing state is good, and fertility is normal.
2, acute dermal toxicity test
According to the requirement of national standard Gsl5670-1995 agriculture chemical registration toxicology test method, carried out the acute dermal toxicity test.With reference to above-mentioned result of the test, and, select gadolinium nitrate berberine complex maximum dose 2000mg/kg according to the requirement of acute dermal toxicity grade scale, in the observation period, physical signs, the health of small white mouse are acted normally, and growing state is good, and fertility is normal.
We reach a conclusion thus, test used agricultural chemicals-gadolinium nitrate berberine complex, belong to low toxicity agricultural chemicals, meet the relevant regulations of China's chemistry security appraisement system.
Three, field experiment
With the tomato bacterial canker is that subjects is carried out simple field experiment, and trial crops is a tomato.The inclined to one side alkali of soil neutral, fertilising, moisture do not wet, soil is the plastic film covering.Use pesticide sprayer to spray, spray area is 10m
2, spraying altogether 2 times, active constituent content is 20g/hm in the spraying agent
2
Fine during the sprinkling, temperature is 18 ℃-32 ℃, and daily mean temperature is 30 ℃, does not have harsh weather during the whole spray medicine.Through to the spray medicine a few days ago, spray during medicine, the observation of tomato growth in ten days draws behind the spray medicine: the disease rate of propagation behind the spray medicine is slow many before than the spray medicine, this explanation gadolinium nitrate berberine complex can suppress pathogen growth or direct kill pathogens, but the effectively preventing disease.
