Problems solved by technology

The two are used separately, one is high dosage, and the other is troublesome to use
[0006] Although people know that there are many kinds of weeds in rice fields, and the scope of application and advantages and disadvantages of the above two pesticides, they have never been able to use the two in combination, because people do not know how to compound and mix the above two herbicides. Random compounding, due to the incorrect compounding ratio and dosage, not only may cause poor weeding effect, but also may cause phytotoxicity

Abstract

The invention relates to a rice field herbicide composition. The rice field herbicide composition comprises 1.0 weight parts of cyhalofop butyl and 7.0-35.0 weight parts of thiobencarb as effective ingredients and agricultural acceptable pesticide adjuvant adapted to the effective ingredients according to dosage forms. The rice field herbicide composition can effectively remove graminaceous weeds, Cyperaceae weeds and broadleaf weeds and has synergistic effect, thus the pesticide cost is reduced, and the times of usage are reduced.

Description

technical field [0001] The present invention is an improvement to paddy field herbicides, and particularly relates to a kind of herbicide that has high-efficiency killing effects on grass weeds (such as stephenia, barnyardgrass, etc.), Cyperaceae weeds and broad-leaved weeds. Less, using a simple paddy herbicide composition. the Background technique [0002] Weeds in paddy fields have developed into a huge plant community. Weeds in paddy fields absorb and plunder a large amount of light and soil nutrients, which seriously weakens the growth of rice and seriously affects the yield and quality of rice. At present, there are many kinds of weeds in paddy fields, including gramineous weeds, sedge weeds and broad-leaved weeds, especially the weeds of Qianjinzi, barnyardgrass and crabgrass among the gramineous weeds are serious. long. And usually paddy field herbicides all have strong selectivity, good weeding effect to a certain family weeds but very poor to another family weed...
