Background
Triazolam (ipfenbacazone), development code: HOK-201, a triazolinone herbicide for paddy fields, is highly effective on gramineous weeds, annual sedges and some annual broadleaf weeds, particularly on barnyard grass, has long duration and is highly safe even when applied to rice transplantation. The triazolam has strong control effect on barnyard grass weeds by inhibiting cell division and cell growth. It can cause short, little tillering, yellowing, distortion and finally death of barnyard grass weeds. The triazolyl oxamide is applied before or after emergence of weeds, and has excellent control effect on annual weeds such as barnyard grass, cyperus heterophyllus and strangles and perennial weeds such as Chinese iris, cyperus hybridus and the like. The triazolyl oxamide is highly safe to rice in a transplanting period, wide in weed control spectrum and long in lasting period of barnyard grass weeds. The mefenacet is a new tool for preventing and removing weeds in paddy fields, can be flexibly applied, is highly safe to rice, and saves time and labor for rice planters. The structural formula is as follows:
bromobutyric acid (bromobutamide) belongs to anilide herbicides, and can effectively prevent and kill annual weeds such as barnyard grass, monochoria vaginalis, motherwort, arthroncus and perennial weeds such as thin-rod Chinese iris, bodhi feltwort, eleocharis tuberosa, cyperus esculentus and Guapian. Even under the dosage of less than 0.1-0.2 kg/ha, the effect of preventing the thin-rod firefly iris is still high. The product has excellent selectivity between rice and weeds, and in field test, the product is mixed with some herbicides to obtain excellent effect of preventing and killing barnyard grass and palmleaf weeds. The product inhibits cell division and has a slight effect on photosynthesis and respiration. The structural formula is as follows:
at present, the herbicide is often used out of specifications, the problems of drug resistance and phytotoxicity are generated in many places, and great influence is generated on soil. According to the field test, the herbicide mixture can well overcome and reduce the phytotoxicity. Meanwhile, after the two herbicides are compounded, a certain synergistic effect can be achieved, the weeding spectrum is enlarged, and the influence on soil can be reduced. Therefore, the two effective components of the triazolyl oxamide and the bebutamid are compounded to achieve the effect.

Detailed Description
The applicant firstly carries out weeding tests on the two effective components of the triazolam and the bebutamid under the condition of a room-temperature pot culture so as to evaluate the weeding effect of the two components in a compounded mode. According to the weeding spectrums of the two effective components, the raw objects are barnyard grass and Chinese iris, and the specific implementation conditions are as follows:
test agent solution: accurately weighing a certain weight of technical materials of the triazolyl oxamide and the bromobutyric acid amide, dissolving the technical materials by using a proper amount of dimethylformamide, adding the technical materials into clear water containing 0.1 percent of Tween 80 emulsifier, and stirring the technical materials uniformly to obtain a solution containing a certain effective component. Blank control solution: an equivalent amount of dimethylformamide was added to an equivalent amount of 0.1% tween 80 emulsifier in water.
The test method is as follows: the activity of the mixed medicament on barnyard grass and Chinese iris is detected by a gowing method, the test soil is quantitatively loaded to 4/5 parts of a pot, the soil is completely moistened by adopting a pot bottom infiltrating irrigation mode, the preprocessed mixed grass seeds for testing are uniformly sown on the surface of the soil, and then 0.5 cm-2 cm of soil is covered according to the size of the seeds. And performing soil spraying treatment after seeding for 24 hours. Each treatment was repeated 4 times, using a blank solution as a control. After treatment, the mixture is placed in a greenhouse for conventional culture, and water is supplemented in an infiltrating irrigation mode at the bottom of the pot. And recording dynamic temperature and humidity data in the greenhouse during the test by using a temperature and humidity digital recorder. After 21 days, the herbicidal activity was recorded, the fresh weight of the plant was weighed, and the fresh weight inhibition (%) was calculated.
The action evaluation method is used for evaluating the combined action mode of the herbicides according to the gowing method, and the formula is as follows:
E0(％)＝X+Y×(100-X)/100
C＝E-E0
in the formula E0The herbicide composition is a theoretical control effect on weed inhibition after two effective components are mixed, E is an actual measurement control effect on weed inhibition after the two effective components are mixed, X is the control effect on target weeds under the dosage of the triazamide, Y is the control effect on the target weeds under the dosage of the bromobutylachlor, C is a combined action coefficient of a mixed preparation and is used for evaluating the synergistic action of the two effective components, when C is more than 10 percent, the synergistic action is realized, when C is less than 10 percent, the antagonistic action is realized, and when C is +/-10 percent, the additive action is realized.
TABLE 1 raw test results of herbicidal activity against barnyard grass with different proportions of triazolam and bebutamid
As can be seen from the table 1, after the triazolyl oxamide and the bebutamid are compounded, the effect of preventing barnyard grass is good, the combined action coefficient (C) is greater than 12, and the synergistic effect of the two effective components after being compounded is obvious.
TABLE 2 crude test results of herbicidal activity of triazolyl oxamide and beflubutamid on Fluoritan in different proportions
