Fluroxypyr.cyhalofop-butyl compound weedicide

Abstract

The invention relates to a fluroxypyr.cyhalofop-butyl compound weedicide and belongs to the technical field of pesticide. The aim of the invention is to provide the fluroxypyr.cyhalofop-butyl compound weedicide which can prevent and remove both grassy weed and broadleaf weed of a paddy field, has no influence on succession crop, is environment-friendly and has economic price. The fluroxypyr.cyhalofop-butyl compound weedicide comprises the following main technical points that: the fluroxypyr.cyhalofop-butyl compound weedicide is prepared from raw materials and auxiliary materials in percentage by mass: 15 to 60 percent of fluroxypyr, 5 to 20 percent of cyhalofop-butyl, 2 to 15 percent of cosolvent, 5 to 15 percent of surfactant and a solvent replenished till 100 percent. The fluroxypyr.cyhalofop-butyl compound weedicide is safe to paddy; 90 g of the weedicide is used in one mu of the paddyfield and can achieve excellent weeding effect; the weed preventing effect can achieve over 80 percent for thirty days and achieve over 90 percent for sixty days; and with the increase of dosage, the preventing effect is obviously strengthened; and once application of the weedicide can prevent and remove the weeds in the whole growth period and has no influence on the succession crop. The fluroxypyr.cyhalofop-butyl compound weedicide is used for preventing and controlling the weeds of the paddy field.

Description

Technical field: [0001] The invention relates to a fluroxypyr-cyhalofop-ester compound herbicide, which is used for preventing and treating weed damage in rice fields and belongs to the technical field of pesticides. Background technique: [0002] Rice is one of the main crops in my country. With the continuous expansion of its planting area, rice field weed damage is increasing day by day in the expanding production, and the damage is becoming more and more serious. Among them, the area of ​​rice field weed damage accounts for 25% of the total planting area Above, more than 7% of the severely affected area, generally more than 13% reduction in production, and even no harvest in severe cases. Therefore, whether it can effectively control the weed damage in rice and stabilize the high yield of rice has become one of the main topics of modern agricultural herbicide research. [0003] At present, among the various paddy field herbicides on the market, cyhalofop-butyl (cyhalofop...

AI Technical Summary

Problems solved by technology

[0003] At present, among the various paddy field herbicides on the market, cyhalofop-butyl (cyhalofop-butyl) is a systemic conduction type aryloxyphenoxypropionic acid herbicide, which is absorbed by plant leaves or leaf sheaths, conducts in phloem, and accumulates with plants. Meristem, inhibiting acetyl-CoA carboxylase, stopping fatty acid synthesis, loss of plant meristematic ability, and finally plant death

Although it can better prevent and control weeds in rice fields, its biggest defect is that the cost of prevention and control is too high.

Therefore, it is difficult to be accepted by the majority of drug farmers
