Problems solved by technology

[0004] CN1213498A patent discloses the composition of aniline pesticides dimethosamine and atrazine. Although there is a synergistic effect, dimethosamine in the composition has poor stability, high volatility and easy photolysis. The composition can only be used in seedlings. It is used for soil surface treatment before, and shallow concrete is required when using it, which requires a lot of work
The composition has narrow adaptability to soil quality and moisture conditions, cannot be used after seedlings, and has poor safety

Abstract

The composite weedicide suspo emulsion for cornfield is a compounded preparation formed from atrazine and aniline agricultural chemicals according to relative mixing ratio of 1:10-10:1. Said invented preparation is an excellent weedicide for preventing and controlling weed in cornfield, and possesses obvious synergized action for monocotyledonous and dictyledonous weeds, and their co-toxic coefficients are greater than 150, so that said invented product has the advantages of synergistic action, broad weeding spectrum, low toxicity and low residue in soil, low cost and safe use, etc.

Description

Technical field: [0001] The invention relates to the field of suspoemulsion pesticide preparations, and relates to the improvement technology of compound herbicide suspoemulsion used in cornfields. Background technique: [0002] Pesticide mixed preparations have multiple functions such as increasing drug efficacy, reducing costs, expanding control spectrum, saving labor, delaying resistance, etc., and are an important aspect of the development of pesticide formulations. As reported in the literature, the mixed use of s-triazine and amide herbicides can expand the herbicidal spectrum, increase drug efficacy and reduce costs. In order to avoid environmental pollution caused by pesticide emulsifiable concentrates and wettable powders, and to reduce the toxicity to operators, the ZL93100089.0 patent made suspoemulsions of atrazine and amides compound herbicides, which solved the above problems well. Use of atrazine wettable powder, etc. on the environment and the operator's poi...
