Problems solved by technology

[0004] However, when fomesafen and clethodim are made into emulsifiable concentrate or water emulsion, clethodim will degrade rapidly. Under the condition of 36°C, the monthly degradation rate is 6%, which seriously affects the use effect of the mixture

[0043] Stabilizer N-methyldiethanolamine 10kg,

[0044] Tween 80 10kg,

[0045] The remainder is water;

[0046] The preparation steps are as follows:

[0047] (1) 15kg of fomesafen and 20kg of dimethylformamide were mixed, stirred, and fomesafen was completely dissolved to obtain mixture A;

[0048] (2) mixing material A with 15kg clethodim and 10kgN-methyldiethanolamine, stirring evenly to obtain mixing material B;

[0049] (3) Mix 30kg of water and 10kg of emulsifier, stir evenly, add mixture B, stir well, and make water emulsion.

[0050] After the production is completed, the product content is tested, and the product is packaged after passing the test.

Abstract

The invention relates to the technical field of weedicide for soybean fields, in particular to a fomesafen and clethodim weedicide for soybean fields, which comprises the following raw materials in percentages by weight: 10-15% of fomesafen, 10-15% of clethodim, 15-20% of dimethylformamide, 5-10% of stabilizer N-methyl diethanolamin, 5-10% of emulsifier and the balance of water. The fomesafen and clethodim weedicide is prepared by the following steps of: mixing the fomesafen and the dimethylformamide together; mixing the mixture with the clethodim and the N-methyl diethanolamin; mixing the water and the emulsifier together and stirring uniformly, and finally mixing with other raw materials and stirring uniformly. The invention has the advantages of improving the stability of the clethodim and avoiding the degradation of the clethodim, eradicating weeds in soybean fields completely at one time, having better prevention and control effect on single-cotyledon weeds and preventing killed weeds from regrowing; in addition, the invention also has the advantages of labor saving, time saving, money saving, low cost, simple process, farmer burden reduction, no harm to seedlings and no influence on yield.

Description

technical field [0001] The invention relates to the technical field of soybean field herbicides, in particular to a soybean field herbicide of fomesafen and clethodim. Background technique [0002] According to "The Current Situation and Prospect of Herbicide Use in Northeast Soybean Fields"--"Shandong Pesticide Information" Issue 07, 2007, since the herbicides used in soybean fields in recent years are mainly fomesafen, quizalofop, and acetochlor , metolachlor, prethoxydim, chlorimuron-methyl, clomazone, and propachlor, etc., all of which can only control gramineous weeds or broad-leaved weeds, and there is no product that can also control all soybean fields. Weeds, and because different weeds have different resistance to herbicides, the population density and composition of weeds have changed in fields that have been chemically weeded for many years, such as amaranth, commelina, and bracken in spring soybean production areas. etc. have risen as the main weeds that are dif...
