Embodiment 1

[0025] Example 1: 12.75% fluroxypyr-bicyclic sulcotrione oil suspension

[0026] The components of the pesticide composition containing fluroxypyr and bicyclic sulcotrione are: fluroxypyr 6%, bicyclic sulcotrione 6.75%, phenethylphenol polyoxyethylene ether 5%, lignin sulfonate 8% Sodium Oleate, 5% Epoxidized Soybean Oil, 5% Organic Bentonite, 100% Methyl Oleate.

[0027] After the fluroxypyr is absorbed and mixed with the filler, the other above-mentioned materials (except organic bentonite) are added into the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the ground materials are fine 98% pass through 1-5um and discharge. The material is put into a high-shear emulsification kettle together with organic bentonite dissolved in advance. After emulsification, it can be made into 12.75% fluroxypyr-bicyclosulfotrione oil suspension agent.

Embodiment 2

[0028] Example 2: 20% fluroxypyr-bicyclosulfotrione suspension concentrate

[0029] The components of the pesticide composition containing fluroxypyr and bicyclic sulcotrione are as follows: fluroxypyr 8%, bicyclic sulcotrione 12%, phenethylphenol polyoxyethylene ether 5%, lignin sulfonate Sodium phosphate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0030] After the fluroxyfen and the filler are adsorbed and mixed, the other above-mentioned materials (except xanthan gum) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the ground materials Fineness of 98% passes through 1-5um, and the material is discharged after passing through 1-5um. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 20% fluroxypyr-bicyclosulfotrione...

Embodiment 3

[0031] Example 3: 35% fluroxypyr-bicyclic sulcotrione wettable powder

[0032] The components of the pesticide composition containing fluroxypyr and bicyclic sulcotrione are: 20% of fluroxypyr, 15% of bicyclic sulcotrione, 3% of sodium butyl naphthalene sulfonate, calcium lignosulfonate 5%, silica 5%, kaolin to 100%.

[0033] After the fluroxypyr is adsorbed and mixed with the filler, it is added to the conical mixer together with other above-mentioned materials and mixed evenly, and then pulverized by the jet mill, and the pulverized material is then mixed by the conical mixer, and the mixed material is fine The 35% fluroxypyr-bicyclic sulcotrione wettable powder can be obtained by passing through a 325-mesh standard sieve with a degree of 98%.

Abstract

The invention discloses a pesticide composite comprising fluroxypyr and benzobicyclon and application of the pesticide composite in prevention of lemnaceae plants. Active ingredients of the pesticide composite include the fluroxypyr and the benzobicyclon. The mass ratio of the fluroxypyr to the benzobicyclon is (1-150): (0.5-30). 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 fluroxypyr and bicyclic sulcotrione for controlling duckweed plants. 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 will cause serious pollution to the water body. The main hazards of duck...
