Composite herbicide preparation for removing field weeds

Abstract

The invention discloses a composite herbicide preparation for removing field weeds. The composite herbicide preparation comprises, by weight, 8-12 parts of an acrylic acid-maleic anhydride copolymer, 6-8 parts of a herbicide, 4-6 parts of avermectin, 2-4 parts of N-methyl-2-pyrrolidinone, 1-1.2 parts of high-efficiency cypermethrin, 0.2-0.5 parts of fenvalerate, 0.3-0.5 parts of calcium dodecyl benzene sulfonate, 1-3 parts of light calcium carbonate and 2-4 parts of an assistant. The composite herbicide preparation has a high suspension rate and strong drug effects, has activity better than that of a missible oil preparation utilizing a toluene solvent, obviously improves weeding effects, greatly reduces a use amount of the herbicide in field, is conducive to prevention of resistance to the herbicide, effectively reduces environment pollution and pesticide residues and belongs to a green eco-friendly novel herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound pesticide preparation for eliminating weeds in the field. Background technique [0002] Intertillage weeding is a traditional method of weeding. The weeds growing in the crop field can be controlled and eliminated in time through manual and mechanical intertillage. Intertillage weeding is highly targeted, clean and thorough, and the technology is simple. It can not only prevent and control weeds, but also provide good growth conditions for crops. During the whole process of crop growth, multiple intertillage and weeding can be carried out according to the needs. When weeding, we should seize the favorable opportunity to weed out early, small and thorough, and weeds should not be left to avoid future troubles. During intertillage and weeding, the masses summed up that "it is better to weed the buds than to weed the Lord", that is to say, weeds should be ...

AI Technical Summary

Problems solved by technology

Manual intertillage weeding has a clear goal, is easy to operate, does not leave a place for the machine to walk, and has a good weeding effect. It can not only remove weeds between rows, but also can remove weeds between plants, but the method is relatively backward and the work efficiency is low.

Mechanical intertillage weeding is more advanced than manual intertillage weeding, and has high work efficiency, but the flexibility is not high. Generally, this method is used in farms with a relatively high degree of mechanical ratio.

[0003] At present, the solvents used in pesticide emulsifiable concentrate preparations are mainly toluene and xylene, but the large-scale use of toluene and xylene has produced many problems, such as toluene and xylene are irritating to the skin and mucous membranes, and have an anesthetic effect on the central nervous system. Inhalation of high concentration in a short period of time can cause obvious eye and upper respiratory tract irritation symptoms, and toluene and xylene have low solubility in water, so they can float or distribute on the water surface in oily form, resulting in the death of fish and other aquatic organisms. cause environmental pollution

In addition, toluene and xylene are also highly volatile and flammable, posing safety hazards during transportation and use

[0004] In recent years, due to single and unscientific use of pesticides, weeds in the field have developed varying degrees of resistance to many pesticides currently used, and herbicide varieties have also produced higher levels of resistance. There are few effective herbicide varieties, which will further aggravate the development of weed resistance. Therefore, new products with high efficiency, broad spectrum and good environmental compatibility are urgently needed as rotation drugs in resistance management

Aiming at the problems of various kinds of adjuvants used in pesticide preparations, unstable quality, low suspension rate of produced pesticide products and poor efficacy, these are the technical problems to be solved by the present invention
