Embodiment 1

[0012] Embodiment 1: Suspension seed coating agent, the mass parts of components are: Clothianidin 1-50 parts; Fludioxonil 0.1-20 parts; Mefenaxyl 0.1-20 parts; Dispersant 5-20 parts; 1-5 parts of agent; 0.1-2 parts of thickener; 0.1-0.8 parts of defoamer; 0-10 parts of penetration enhancer; 0.2-5 parts of film-forming agent; parts; water, the remainder. The specific production steps of the suspending agent are as follows: first mix other additives, mix evenly through high-speed shearing, add clothianidin, fludioxonil and mefenaxyl, and grind the balls in a ball mill for 2 to 3 hours to make the granules If the diameters are all below 5mm, the suspension preparation of the composition of the present invention can be prepared.

Embodiment 2

[0013] Embodiment 2: Wettable powder, the mass parts of components are: Clothianidin 1-50 parts; Fludioxonil 0.1-20 parts; Mefenaxyl 0.1-20 parts; Dispersant 3-10 parts; Wetting agent 1 to 5 parts; filler, the balance. The specific production steps of the wettable powder are: mix clothianidin, fludioxonil, metalaxyl-fine, dispersant, wetting agent and filler according to the above formula, stir evenly in a stirring tank, and put them in the Mix evenly, then the wettable powder of the composition of the present invention can be prepared.

Embodiment 3

[0014] Embodiment 3: Water-dispersible granules, the mass parts of components are: Clothianidin 1-50 parts; Fludioxonil 0.1-20 parts; Mefenaxyl 0.1-20 parts; Wetting agent 1-10 parts; 1 to 5 parts of decomposing agent; filler, the rest. The specific production steps of the water-dispersible granules are: according to the above formula, clothianidin, fludioxonil, metalaxyl, dispersant, wetting agent, disintegrating agent and filler are uniformly mixed, and pulverized by an ultra-fine jet mill , after kneading, then put into a fluidized bed granulation dryer for granulation, drying, sieving, and after sampling and analysis, the water-dispersible granules of the composition of the present invention can be prepared.

Abstract

The invention relates to a seed treatment composition containing clothianidin. The seed treatment composition comprises the following effective components in parts by mass: 1-50 parts of clothianidin as insecticide, 0.1-20 parts of fludioxonil as bactericide and 0.1-20 parts of metalaxyl-M which are in ternary distribution, auxiliary components including 1-5 parts of a dispersant, 1-5 parts of a wetting agent and 1-5 parts of an adhesive, and the balance being filler and / or deionized water. The mass ratio of the insecticide clothianidin to the bactericide fludioxonil to the metalaxyl-M is (1-50):(0.1-20):(0.1-20); the total mass of the insecticide clothianidin, the bactericide fludioxonil and the metalaxyl-M in the preparation accounts for 1-60% of mass of the overall preparation. The dosage forms of the seed treatment composition are suspended seed coatings, wettable powder, water dispersible granules, granules, dry mixing agents and microcapsules; the seed treatment composition is applied to prevention and treatment of underground pests such as grub, wireworm and cutworm, and insect pests such as aphid, plant hopper and thrips, and is applied to prevention and treatment of diseases such as tilletia caries, banded sclerotial blight, full rot, fusarium patch, gray mold, downy mildew, phytophthora capsici and pythium diseases.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal and bactericidal seed treatment composition composed of insecticide clothianidin, fungicides fludioxonil and mefenaxyl. Background technique [0002] Clothianidin is a neonicotinoid insecticide jointly developed by Bayer and Japan’s Takeda, and its chemical name is (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl) - 3-methyl-2-2-nitroguanidine. Clothianidin is a new type of insecticide with high efficiency, safety and high selectivity. Its action is similar to that of nicotinic acetylcholine receptor, and it has contact killing, stomach poisoning and systemic activity. It is mainly used as an insecticide for preventing and controlling aphids, leafhoppers, thrips, planthoppers and other pests of Hemiptera, Coleoptera, Diptera and some Lepidoptera on rice, vegetables, fruit trees and other crops. It has the advantages of broad spectrum, less dosage, low toxici...
