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% TERSPERSE2020 (produced by Huntsman, USA), 4% Span-60#, 3% Tween-60#, 3% Nongru 2201#, 3% Nongru 700#, 1% TERSPERSE2500 (produced by Huntsman, USA), 0.5% silica, 2% epichlorohydrin, 0.5% silicone defoamer (trade name: s- 29 Nanjing Sixin Applied Chemicals Co., Ltd.), 1% triacontanol, methyl oleate 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% TERSPERSE2500, 1% magnesium aluminum silicate, 1.5% butylhydroxyanisole, 0.6% L-1000 silicone defoamer (produced by Shanghai Liqi Chemical Auxiliary Co., Ltd.), 2.5% naphthalene acetic 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 suspension containing florasulam and 2-methyl-4-chloro-isooctyl, which consists of effective active ingredients of florasulam and 2-methyl-4-chloro-isooctyl, as well as a dispersant and an emulsifier , wetting agent, thickener, stabilizer, defoamer, synergist and vegetable oil. The invention adopts the mixing scheme of two effective active ingredients, and the prevention effect is better than that of a single agent, and has a synergistic effect. The herbicidal effect of the prepared dispersible oil suspension concentrate is obviously better than other formulations. It has a good control effect on various broad-leaved weeds in the wheat field, can reduce the cost of control, has good safety for crops, and meets the safety requirements of pesticide preparations .

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...
