Problems solved by technology

For example, the prepared wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, etc., resulting in uneven spraying and local phytotoxicity of crops. The main reason is that it helps There are different defects in the selection of agents and fillers
[0006] 3), compounding problem, by carrying out toxicity test, thermal storage stability test and co-toxicity coefficient measurement to the above-mentioned several specific proportions disclosed by several herbicidal compositions, it is found that no obvious synergistic effect can be achieved

Abstract

The invention provides compound missible oil containing oxadiazon and simetryne and a preparation method thereof and relates to the technical field of prevention and treatment of weeds of paddy fields. The compound missible oil is prepared from 12 parts of oxadiazon, 13 parts of simetryne, 6 parts of tristyrylphenol ethoxylates, 3 parts of ethoxylated distyrylphenol formaldehyde condensate, 9 parts of calcium dodecyl benzene sulfonate and 57 parts of xylene. The preparation method comprises the following steps: adding oxadiazon and simetryne to xylene and stirring until all the components are dissolved; then adding the residual raw materials, and stirring and mixing uniformly with a reaction kettle; sampling and analyzing the content; after the raw materials are qualified, standing, filtering, packaging, and sampling and analyzing the content again; and storing after the product is qualified. The compounded compound missible oil containing oxadiazon and simetryne, with the concentration of 25%, is used by mixing oxadiazon and simetryne at the ratio of 12 to 13, and has an obvious synergistic effect range; and preparations, which are mixed at other ratios, cannot reach the obvious synergistic effect range.

Description

technical field [0001] The invention relates to the technical field of weed prevention and control in paddy fields, in particular to a compounded EC of oxadiazone and siquat and a preparation method thereof. Background technique [0002] At present, the existing herbicidal composition for controlling weeds in paddy fields, for example, Chinese patent "CN103975934A" discloses a "herbicidal composition containing oxadiazone", wherein the effective active ingredients are oxadiazone, pretilachlor and For penoxsulam, the ratio of the three is 1-50:1-80:1-40. Another Chinese patent "CN104823987A" discloses a "herbicidal composition containing trifenazole and oxadiazone", wherein the effective active ingredients are trifenamide and oxadiazone, and the ratio of the two is 10 :1~1:10. [0003] The inventor has verified through long-term experiments that the above-mentioned several herbicidal compositions mainly have the following defects: [0004] 1), through the test of several s...
