Problems solved by technology

At present, the dosage forms of seed coating agents popularized and used in China are mainly water-suspended. Since most of the medium of water-suspended seed treatment agents is water, it is easy to freeze in the alpine regions of Northeast China, which not only affects the physical and chemical properties of the preparation itself, but also affects the preparation. The requirements for packaging materials are also more stringent, which virtually increases the cost

Embodiment 1

[0028] Example 1 25% tefluthrin·fluxazone seed treatment dispersible powder

[0029] The formula is: 20 parts of tefluthrin, 5 parts of pyraclostrobin as the active ingredient of the pesticide; 3 parts of sodium lignosulfonate as the wetting and dispersing agent, 6 parts of formaldehyde condensate of naphthol sulfonate salt; polyvinyl alcohol as the film forming agent 2 parts, 1 part of sodium polyacrylate; 2 parts of acid scarlet as a colorant; 6.7 parts of diatomite as a filler, and 100 parts of kaolin.

[0030] The preparation method is as follows: put tefluthrin, pyraclostrobin, wetting and dispersing agent, film-forming agent, coloring agent, and filler into a mixing tank, stir for 30 minutes to make the material uniform, and then pulverize the material through an airflow pulverizer, The temperature is controlled at 30-35°C, passed through a 325-mesh sieve, and packed to obtain a crimson loose powder, which is weighed and packaged to obtain the finished seed treatment dis...

Embodiment 2

[0031] Example 2 35% tefluthrin·fluxazone seed treatment dispersible powder

[0032] The formula is: 27 parts of tefluthrin and 8 parts of pyraclostrobin as active ingredients of pesticides; 3 parts of sodium lignosulfonate as a wetting and dispersing agent, 6 parts of formaldehyde condensate of naphthol sulfonate salt; polyvinyl alcohol as a film forming agent 2 parts, 1 part of sodium polyacrylate; 2 parts of acid scarlet as a coloring agent; 5 parts of diatomite as a filler, and 100 parts of kaolin. The preparation method is the same as in Example 1.

Embodiment 3

[0033] Example 3 40% tefluthrin·fluxazone seed treatment dispersible powder

[0034] The formula is: 30 parts of tefluthrin and 10 parts of pyraclostrobin as the active ingredients of pesticides; 3 parts of sodium lignosulfonate and 6 parts of naphthol sulfonate formaldehyde condensate as wetting and dispersing agent; polyvinyl alcohol as the film forming agent 2 parts, 1 part of sodium polyacrylate; 2 parts of acid scarlet as a coloring agent; 5 parts of diatomite as a filler, and 100 parts of kaolin.

[0035] The preparation method is the same as in Example 1.

Abstract

The invention discloses a pesticide composition containing tefluthrin and sedaxane and a preparation method and application thereof. The pesticide composition comprises, by weight, 20-60% of tefluthrin and 5-15% of sedaxane. The preparation method comprises the steps of mixing tefluthrin and sedaxane to prepare seed treatment dispersible powder which has the advantages of being good in filming, uniform in coating, high in suspension rate, good in safety, low in toxicity and the like, and can be widely applied to the treatment of the seeds (yams) of wheat, corn, peanuts, potatoes and the like, the prevention of the infestation of grub, wire worm, flea beetle, leaf beetle and the like in the crops, and the blight, rot root, damping-off, loose smut, drooping disease, head smut and many other diseases in the seedling stage of the crops. Compared with the single tefluthrin and single sedaxane, the pesticide composition containing tefluthrin and sedaxane has an increased pest killing and anti-disease effects.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing tefluthrin and fenfluxam, its seed treatment dispersible powder dosage form, its preparation method and application, and belongs to the technical field of chemical pesticides. Background technique [0002] Tefluthrin is the first pyrethroid insecticide that can be used as a soil insecticide. It is highly effective against Coleoptera, Lepidoptera and Diptera insects and can be applied as granules, soil spray or seed treatment , it has good volatility and can fully migrate in the gas phase to control soil pests. The half-life in the field is about one month, so it can maintain a long residual effect on pests without causing long-term residues in the soil. [0003] Fluxazone is a new type of pyrazole amide fungicide developed in recent years, which has the functions of protection, treatment and systemic absorption. The bactericide is a succinate dehydrog...
