Problems solved by technology

For example, 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, resulting in uneven spraying
[0006] 3), compounding problem, by carrying out toxicity test, thermal storage stability test and mixing co-toxicity coefficient measurement to several specific proportions disclosed by the above-mentioned several herbicidal compositions, it is found that no obvious synergistic effect can be achieved

Embodiment 1

[0022] 30% bentazone and cyhalofop-ethyl compound suspension concentrate, each component and its weight ratio are as follows:

[0023] Element parts by weight Benedazone 20 Cyhalofop-methyl 10 Fatty alcohol polyoxyethylene ether 3 Styrylphenol polyoxyethylene ether 3 xanthan gum 0.3 sodium benzoate 0.4 Defoamer 0.3 Deionized water 63

[0024] Preparation method: The raw materials are pumped into the preparation tank for mixing and stirring, and then firstly ground by a colloid mill, then finely ground by a sand mill, sampled and analyzed, filtered, measured, packaged, and put into storage after passing the test.

Embodiment 2

[0026] 29% bentazone and cyhalofop compound suspension concentrate, each component and its weight ratio are as follows:

[0027] Element parts by weight Benedazone 19 Cyhalofop-methyl 10 Fatty alcohol polyoxyethylene ether 3 Styrylphenol polyoxyethylene ether 3 xanthan gum 0.3 sodium benzoate 0.4 Defoamer 0.3 Deionized water 64

[0028] The preparation method is the same as in Example 1.

Abstract

The invention provides a bentazone / cyhalofop-butyl compound suspending agent and a preparation method thereof, relating to the technical field of annual weed control in a transplanted rice paddy field. The bentazone / cyhalofop-butyl compound suspending agent is prepared from at least 20 parts of bentazone, 10 parts of cyhalofop-butyl, 3 parts of fatty alcohol polyethenoxy ether, 3 parts of styryl phenol polyethenoxy ether, 0.3 part of xanthan gum, 0.4 part of sodium benzoate, 0.3 part of defoaming agent and the balance of deionized water, totaling 100 parts. The preparation method comprises the following steps: sucking all the raw materials into a preparation kettle, mixing and stirring, carrying out primary grinding by a colloid mill, carrying out fine grinding by a sand mill, carrying out sample analysis, filtering the acceptable product, metering, packaging and warehousing. The 30% compound suspending agent composed of bentazone and cyhalofop-butyl in a ratio of 2:1 can have an obvious synergistic action, but the preparations with other ratios can not reach the obvious synergistic action range.

Description

technical field [0001] The invention relates to the technical field of prevention and control of annual weeds in transplanted rice fields, in particular to a compound suspending agent of bentazone and cyhalofop-methyl and a preparation method thereof. Background technique [0002] At present, the existing herbicidal composition for controlling annual weeds in transplanted rice fields, for example, Chinese patent CN103688969 A discloses a "herbicidal composition for controlling annual weeds in rice fields", the active ingredient is pretilachlor , bensulfuron-methyl and oxaziclozone, the percentage by weight of pretilachlor in the composition is 1% to 50%, the percentage by weight of bensulfuron-methyl in the composition is 1% to 10%, and oxaziclozone The weight percentage in the composition is 1%-30%, and the rest is pesticide adjuvant. Another Chinese patent CN 104886099 A discloses a "paddy field herbicidal composition", which is composed of active ingredients A, B and sui...
