preparation Embodiment

[0019] The content of the present invention will be further described below in conjunction with the examples, and the active ingredient in the formulation examples is the weight after 100 percent.

[0020] Formulation Example 1 25% Picarbutrazox · Metalaxyl Suspension Concentrate

[0021] Weigh 15% metalaxyl, 10% Picarbutrazox, 5% sodium methylene bis-naphthalene sulfonate, 6% pull-off powder, 3% glycerol, 0.2% magnesium aluminum silicate, 0.8% organic silicon, water supplement to 100%. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 After less than 10 microns, a 25% fine metalaxyl · Picarbutrazox suspension was prepared.

Embodiment 2 2

[0022] Preparation Example 2 22% Picarbutrazox·Metalaxyl EC

[0023] Weigh 14% metalaxyl, 8% Picarbutrazox, 10% N-methylpyrrolidone, 6% phenylphenol polyoxyethyl ether, 4% alkylphenolic resin polyoxyethyl ether, and add vegetable oil to 100%. Mix active pesticide ingredients, co-solvents, emulsifiers, and solvents in proportion, and mix and stir in the preparation kettle. After completely dissolving, add the remaining solvent slowly, and get a uniform oil phase after fully stirring to make 22% Picarbutrazox · Nail Cream Cream

Abstract

The invention relates to a bactericidal composition containing Picarbutrazox and metalaxyl-M. The weight ratio of the two effective components is 1-50:50-1. The bactericide comprises 1-70% weight percentage of the effective components, preferably 5-50%, and the balance assistants and carriers allowable in pesticides. The composition provided by the invention has obvious synergistic effect, can reduce the pesticide dosage, and is friendly and safe to the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide composition containing Picarbutrazox and metalaxyl. Background technique [0002] Picarbutrazox belongs to carbamate fungicides and is an active ingredient with a new mode of action, which can be used to inhibit fungal diseases of Oomycetes, such as Peronospora sp. Is a disease. Applied crops include melon vegetables, grains, tomatoes, potatoes, turf, lettuce and other leafy vegetables. [0003] . [0004] Picarbutrazox chemical structure [0005] Metalaxyl-M is an amide fungicide developed by Syngenta, which is the R-isomer of ordinary metalaxyl, and is a highly efficient systemic fungicide. It has a good control effect on crop diseases such as vegetables, fruit trees, tobacco, oilseeds, cotton and grains caused by downy mildew, Phytophthora, and Pythium. [0006] Grape downy mildew (Plasmoparaviticola) is a worldwide disease, which has the characteristics ...
