Problems solved by technology

The wheat seed dressings currently on the market can only act on a single pest or disease, and a single seed dressing cannot achieve a good control effect
[0006] In order to solve the problems of soil-borne diseases and insect pests and plant disease-prone insect pests in the seedling stage, the effect of medication in the later stage is not obvious, and repeated medication causes high cost of use and serious pollution. Combination seed dressing formula

Embodiment 1

[0045] Embodiment 1 45% thiamethoxam+5% clothianidin suspension seed coating

[0046] Thiamethoxam 45%, Thiofuramide 5%, Polyethylene glycol 5%, Styrene polyoxyethylene ether ammonium sulfate 5%, Sodium lauryl sulfate 3%, Sodium lauroyl sarcosinate 2%, Ethylene glycol Alcohol 0.5%, hydroxymethyl cellulose 0.5%, silicone oil 0.5%, basic rhodamine 0.5%, and water make up 100%.

[0047] The preparation method is as follows: polyethylene glycol, styrene polyoxyethylene ether ammonium sulfate, sodium lauryl sulfate, sodium lauroyl sarcosinate, ethylene glycol, hydroxymethyl cellulose, silicone oil and water are subjected to high-speed shearing Cut and mix evenly, then add thiamethoxam and thiafluxamide to a sand mill and grind for 2.5 hours, so that the particle size is all below 5 μm, and finally add alkaline rhodamine, mix evenly, and then make a suspension seed coating agent.

Embodiment 2

[0048] Example 2 36% thiamethoxam+6% clothianidin suspension seed coating

[0049] Thiamethoxam 36%, Thiofuramide 6%, Modified Starch 7%, Alkylphenol Polyoxyethylene Tetraether (OP-4) 3%, Alkyl Naphthalene Formaldehyde Condensate Sodium Sulfonate 6%, Dodecane Sodium Hydroxysulfate 0.5%, Propylene Glycol 0.8%, Hydroxyethyl Cellulose 0.8%, Silicone 0.5%, Basic Rhodamine 1%, Water Make Up 100%.

[0050] The preparation method is: first mix modified starch, alkylphenol polyoxyethylene tetraether (OP-4), sodium alkylnaphthalene formaldehyde condensate sulfonate, sodium lauryl sulfate, propylene glycol, hydroxyethyl cellulose, silicon Ketone and water are mixed evenly by high-speed shearing, then add thiamethoxam and thiafuramide and grind them in a sand mill for 3 hours, so that the particle size is all below 5 μm, and finally add rhodamine alkaline, mix evenly, and then make a suspension Seed coating agent.

Embodiment 3

[0051] Example 3 20% thiamethoxam + 10% clothianidin suspension seed coating

[0052] Thiamethoxam 20%, Thiofuramide 10%, Polyvinylpyrrolidone 4%, Styrene Polyoxyethylene Ether Ammonium Sulfate 4%, Sodium Oleate 3%, Sodium Dodecylbenzene Sulfonate 6%, Glycerol 0.3 %, xanthan gum 0.8%, silicone oil 1%, basic rhodamine 0.8%, water make up 100%.

[0053] The preparation method is as follows: first mix polyvinylpyrrolidone, styrene polyoxyethylene ether ammonium sulfate, sodium oleate, sodium dodecylbenzenesulfonate, glycerol, xanthan gum, silicone oil and water through high-speed shearing, Then add thiamethoxam and thiafluxamide and grind in a sand mill for 2 hours, so that the particle size is all below 5 μm, and finally add rhodamine basic, mix evenly, and then make a suspension seed coating agent.

Abstract

The invention relates to a wheat seed coating agent which comprises the following active components: thiamethoxam and thifluzamide in the mass ratio of (2:1) to (20:1), preferably (6:1) to (9:1), wherein the weight percents of the active components, namely thiamethoxam and thifluzamide are 10%-90% of total weight, preferably 10%-70%. The invention further relates to application of the wheat seed coating agent for preventing and treating wheat pests and / or wheat diseases.

Description

【Technical field】 [0001] The invention relates to a wheat seed coating agent, which belongs to the field of agriculture, in particular to a wheat seed coating agent of thiamethoxam and thiafluxamide. 【Background technique】 [0002] In agricultural production, due to the pathogens carried by the seeds themselves, the pathogens in the soil, the airborne pathogens and insect pests at the seedling stage, they often cause crop diseases and insect pests, and even the grains fail in severe cases, which has become an important limiting factor in agricultural production. In the past, in order to protect the seedlings, people adopted the method of increasing the amount of sowing, which wasted seeds and could not eliminate pests and diseases. Faced with these problems, seed treatment agent technology emerged as the times require, showing unique advantages. Using bactericidal and insecticidal pesticides to compound seed dressings is a common method for treating seeds to prevent pests a...
