Problems solved by technology

According to the inventor's investigations in the main wheat planting areas in recent years, it was found that shepherd's purse and Artemisia persicae in Hebei, pig's weed in Henan, and cow chickweed and chickweed in Jiangsu have serious occurrences and serious resistance. The above-mentioned diflusulam , 2-methyl-4-chloroisooctyl single agent can not solve the above problems, increase the dosage and easily produce phytotoxicity, it is urgent to invent a kind of herbicide with good weeding effect, low drug cost, safe and pollution-free

Embodiment 1

[0033] Weigh 0.4% florasulam, 39.6% 2-methyl-4-chloroisooctyl, 2% TERSPERSE 2020 (produced by Huntsman, USA), 4% Span-60#, 3% Tween-60#, 3% % Nongru 2201#, 3% Nongru 700#, 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.5% white carbon black, 2% epichlorohydrin, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), 1% triacontanol, and methyl oleate were added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill until the particle size was less than 5 microns to prepare 40% florasulam·2-methyl-4-chloroisooctyl dispersible oil suspension concentrate.

Embodiment 2

[0035] Weigh 0.2% florasulam, 50% 2-methyl-4-chloroisooctyl, 2% diffusing agent NNO, 3% Nongru 2201#, 10% BY-110, 1% TERSPERSE 2500, 1% magnesium aluminum silicate , 1.5% butyl hydroxyanisole, 0.6% L-1000 silicone defoamer (produced by Shanghai Liqi Chemical Auxiliary Co., Ltd.), 2.5% naphthaleneacetic acid, and soybean oil are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 20 minutes, and sanded with a sand mill until the particle size was less than 5 microns to prepare a 50.2% florasulam·2-methyl-4-chloroisooctyl dispersible oil suspension concentrate.

Embodiment 3

[0037] Weigh 2% florasulam, 20% 2-methyl-4-chloroisooctyl, 3% sodium lignosulfonate, 2% Nongru 2201#, 10% BY-125, 1% alkylphenol polyoxyethylene ether Phosphate ester, 1% xanthan gum, 2% sodium benzoate, 0.5% silicone defoamer, 0.5% triacontanol, and rapeseed oil are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 25 minutes, and sanded with a sand mill until the particle size was less than 5 microns to prepare 22% florasulam·2-methyl-4-chloroisooctyl dispersible oil suspension concentrate.

Abstract

The invention discloses a dispersible oil suspending agent containing florasulam and MCPA-isooctyl. The dispersible oil suspending agent comprises effective active ingredients, namely florasulam and MCPA-isooctyl, a dispersing agent, an emulsifier, a wetting agent, a thickening agent, a stabilizing agent, a defoaming agent, a synergistic agent and plant oil. According to the dispersible oil suspending agent, a scheme of blending two effective active ingredients is adopted, control effect of mixing two effective active ingredients is better than that of a single effective active ingredient, and the dispersible oil suspending agent has a synergistic effect. The prepared dispersible oil suspending agent has the weeding effect obviously better than that of other dosage forms and also has good control effect to various broad leaf weeds in a wheat field, control cost can be reduced, safety to crop is good, and safety requirements to pesticide preparation are met.

Description

technical field [0001] The invention relates to a dispersible oil suspension concentrate composed of two active ingredients of florasulam and 2-methyl-4-chloroisooctyl, and belongs to the technical field of compound pesticides. Background technique [0002] Dispersible oil suspension concentrate uses vegetable oil as the dispersion medium, which is friendly to the environment. After spraying with water on the plant surface, it has good adhesion, spreadability and permeability. To achieve synergistic effect, the dosage of active ingredients can be reduced and the cost can be saved. [0003] Flosulam, also known as Maishida, English common name Florasulam, chemical name: 2',6'-difluoro-5-ethoxy-8-fluoro[1,2,4]triazole[1, 5-C] pyrimidine-2-sulfonanilide. Flusulam is a super-efficient herbicide of the triazolopyrimidine sulfonamide class, mainly used to control broad-leaved weeds in wheat fields, such as pig worms, chickweed, and Maijiagong, etc., but The control effect on Ar...
