Embodiment 1

[0023] Example 1: 32% bispyribac-diflufenamide oil suspension concentrate

[0024] Bispyribac 2%, diflufenican 30%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0025] Put the above materials (except organic bentonite) into the reaction kettle mixer together, stir evenly, inject the materials into the multi-stage sand mill for grinding, the fineness of the ground materials is 98% and pass through 1-5um, and then the materials are discharged, and the materials are mixed with The pre-dissolved organic bentonite is put into a high-shear emulsification kettle together, and after emulsification, a 32% bispyribac-diflufenamide oil suspension concentrate can be made.

Embodiment 2

[0026] Example 2: 42% Bispyribac-Diflufenamide Suspension Concentrate

[0027] Bispyribac 2%, diflufenican 40%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5 %, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0028] Put the above materials (except xanthan gum) into the reaction kettle mixer together, stir evenly, inject the materials into the multi-stage sand mill for grinding, the fineness of the ground materials is 98% and pass through 1-5um, and then the materials are discharged. Put it into a high-shear emulsification kettle together with the pre-dissolved xanthan gum, and after emulsification, it can be made into a 42% bispyribac-diflufenamide suspension.

Embodiment 3

[0029] Example 3: 52% bispyribac-diflufenamide wettable powder

[0030] Bispyribac 2%, Diflufenamide 50%, Sodium Lauryl Sulfate 2%, Sodium Butyl Naphthalene Sulfonate 3%, Calcium Lignosulfonate 5%, White Carbon Black 5%, Kaolin to 100% .

[0031] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill. The pulverized materials are then mixed through the conical mixer. Water-dispersible granules of bispyribac-diflufenamide.

Abstract

The invention discloses a pesticide combination containing bispyribac-sodium and diflufenican and application of the pesticide combination. The bispyribac-sodium and the diflufenican serve as effective components of the pesticide combination; the mass ratio of the bispyribac-sodium to the diflufenican is 1:30-30:1. The pesticide combination achieves an obvious synergism effect within a certain proportion range, the using amount of pesticides, drug use frequency, and the drug use cost are lowered, and an adverse effect of the pesticides on an ecological environment is also alleviated. The weed control spectrum is expanded; due to one-time drug use, various weed problems are solved, and shortcomings and the limitation caused by the use of a single dosage are overcome. The service life of the pesticide combination is prolonged, and the pesticide combination has a great significance for comprehensive treatment of the resistance of weeds. The pesticide effect can be achieved quickly; the lasting period is long; the use cost is low; the pesticide combination can be used for preventing and treating barnyard grasses in rice seedling beds with seedlings transplanted by a rice seeder and other graminaceous weeds as well as treating most broad-leaved weeds and some cyperaceae weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing bispyribac and diflufenamide for controlling weeds in machine-transplanted rice fields. Background technique [0002] The use of pesticides plays an important role in increasing world food production and improving people's living standards. According to statistics, the world's grain production loses 14% every year due to diseases, insects, and weeds, and the loss caused by weeds is about 11%. It can be seen that the damage of weeds has become an important factor affecting crop yield. The use of chemical herbicides can not only save a large amount of labor and increase labor productivity, but also remove weeds between seedlings that are difficult to remove by general machinery, further improve mechanization, and improve traditional cultivation methods. Therefore, the research and application of chemical herbicides has been paid mo...
