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 the operation is difficult, which wastes manpower and material resources

Abstract

The invention discloses a cassava field post-emergence herbicide taking haloxyfop-R-methyl as an effective component, relates to the technical field of herbicides, and is prepared from the following components: modified nano bentonite, haloxyfop-R-methyl, lauryl sodium sulfate, 2-amino-3-chlorobenzoic acid methyl ester, 2,3-difluoro-5-chloropyridine, a licorice alcohol extract, an alfalfa alcoholextract, an antifoaming agent and xylene. The cassava field post-emergence herbicide taking haloxyfop-R-methyl as the effective component prepared by the invention can better inhibit and remove weedsin cassava fields, and is especially effective for inhibition and removal of weeds such as elephant grass, digitaria sanguinalis and cymbopogon citratuse.

Description

technical field [0001] The invention belongs to the technical field of herbicides, in particular to a post-emergence herbicide for cassava fields with high-efficiency haloxyfop-pyl as an active ingredient. 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. success. The advantages of ethanol gasoline, energy saving and environmental protection, replacing the country's scarce resources, has taken an important step for a green and sustainable develo...
