Embodiment 1

[0025] Example 1: 17.8% bicyclic sulcotrione·dicamba oil suspension concentrate

[0026] The components of the pesticide composition containing bicyclic sulcotrione and dicamba are: 1.8% bicyclic sulcotrione, 16% dicamba, 5% phenethylphenol polyoxyethylene ether, 8% sodium lignosulfonate, cyclic Oxygenated soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0027] After absorbing and mixing dicamba and fillers, add the other above-mentioned materials (except organic bentonite) into the reactor mixer, stir evenly, and inject the materials into a multi-stage sand mill for grinding. The fineness of the ground materials is 98% After passing through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, a 13.75% bicyclic sulcotrione·dicamba oil suspension can be prepared.

Embodiment 2

[0028] Example 2: 27.5% Bicyclic Sulfotrione·Dicamba Suspension Concentrate

[0029] The components of the pesticide composition containing bicyclic sulcotrione and dicamba are: 3.5% bicyclic sulcotrione, 24% dicamba, 5% phenethylphenol polyoxyethylene ether, 8% sodium lignosulfonate, ethyl Glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0030] After absorbing and mixing dicamba with the filler, add other above-mentioned materials (except xanthan gum) into the reactor mixer together, stir evenly, inject the materials into a multi-stage sand mill for grinding, and the fineness of the ground materials is 98 % After passing through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, a 36% bicyclic sulcotrione·dicamba suspension can be made.

Embodiment 3

[0031] Example 3: 36% bicyclic sulcotrione · dicamba wettable powder

[0032] The components of the pesticide composition containing bicyclic sulcotrione and dicamba are: 4% bicyclic sulcotrione, 32% dicamba, 3% sodium butylnaphthalene sulfonate, 5% calcium lignosulfonate, white carbon black 5%, kaolin to 100%.

[0033] After absorbing and mixing dicamba and filler, put it into a conical mixer together with other above-mentioned materials and mix evenly, and then pulverize through a jet mill, and then mix the pulverized material through a conical mixer, and the fineness of the mixed material is 98% A 44% bicyclic sulcotrione·dicamba wettable powder was obtained by passing through a 325-mesh standard sieve.

Abstract

The invention discloses a pesticide composite comprising benzobicyclon and dicamba and application of the pesticide composite in prevention of lemnaceae plants. Active ingredients of the pesticide composite include the benzobicyclon and the dicamba. The mass ratio of the benzobicyclon to the dicamba is (0.5-80): (10-300). The pesticide composite has the advantages that obvious synergism is achieved within the matching range, pesticide dosage, dosage frequency and dosage cost are reduced, and adverse effects of pesticides on biological environments are also reduced; weeding spectrums are widened, the problem of harm of various lemnaceae plants is solved by one-time dosage, and defects and limitations in single dosage are overcome; service life of chemicals is prolonged, and the pesticide composite has a significance in comprehensive treatment of herbicide resistance of weeds; the pesticide composite takes effect quickly, pesticide effect lasts long, application cost is low, and the pesticide composite can be applied to prevention and removal of the lemnaceae plants.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing bicyclic sulcotrione and dicamba for preventing and controlling duckweed plants in river courses, ditches, reservoirs, lakes and farmland. Background technique [0002] In recent years, with the sustained and rapid development of the national economy, the environmental pollution of water areas has become increasingly serious, and the occurrence and spread of duckweed plants has accelerated. In some areas, rivers, lakes, and reservoirs have been flooded with duckweed, seriously endangering the ecological balance. Duckweed plants mainly include Ziping, Qingping and Wuping, etc., which are collectively referred to as duckweed. The growth of duckweed needs to consume nutrients such as nitrogen and phosphorus in the water body, and a small amount of duckweed can purify water quality. However, if it grows wildly in a large area, it wil...
