Cassava field post-seedling chemical herbicide using efficient haloxyfop-methyl as effective ingredient

Abstract

The invention provides a herbicide which takes haloxyfop-p-methyl as the active ingredient and is used after cassava seedling is planted in the field; the herbicide consists of haloxyfop-p-methyl and is made into various formulations such as water dispersible granule, suspending agent, wettable powder, aerosol, slow-release agent, aqueous emulsion, missible oil, microemulsion, effervescent tablet and the like, after being added with addition agent and carrier. The herbicide is used for killing weeds in the cassava field. The invention has no drug resistance and excellent effect for killing grassy weeds; the invention can effectively kill weeds like goose grass and cynodon dactylon and has excellent preventative effect on the grassy weeds in the 4 to 6 leaf periods; moreover, the herbicide is safe for cassava with low residue and poison and the active ingredient can be used in the field of nearly all broadleaf plants to prevent and kill the grassy weeds; the operation is simple and convenient, and the cost is lower. Therefore, the invention is easy to be spread.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a single pesticide agent containing high-efficiency haloxyfop, which is mainly used for post-emergence control of cassava grass weeds. Background technique [0002] Cassava has a long history of planting in South China, and it is one of the important sources of income for farmers, and its area is gradually increasing in South China. Cassava is rich in starch and is the main source of starch in my country. As the world enters the 21st century, green and sustainable development has become the theme of the world. my country has begun to vigorously develop the ethanol gasoline project in Beihai, that is, to use green fuel ethanol to replace part of gasoline. This project has achieved great results since its inception. Successfully, ethanol gasoline has been fully used in Guangxi province since April 1, 2008. [0003] The advantages of ethanol gasoline, energy saving and environmental prote...

Problems solved by technology

Among these three types of grasses, grass weeds are the most harmful. The reason is that goosegrass, crabgrass, and tulip grass are all weeds that absorb water, have strong nutrient capacity, grow very fast, and have very tall plants. The damage to cassava in the early stage of emergence is almost devastating, but there is still a gap in domestic weeding agents that can be applied to cassava post-emergence

At present, farmers use cassava herbicides mainly through pre-emergence soil sealing, but because the land where cassava is planted is dry soil, the sealing effect is not ideal; in the face of unsatisfactory effects, farmers also use directional spraying of paraquat, The method of glyphosate is remedied, but this remedial method is very dangerous and difficult to operate, wasting manpower, material resources and financial resources
