Embodiment 1

[0026] Example 1: 8% dinotefuran difenoconazole suspension seed coating

[0027] The content of each component (by weight) is: dinotefuran technical 5%, difenoconazole technical 3%, agricultural milk 6022%, SP-SC32804%, quinone 2%, xanthan gum 0.2% , n-octanol 1%, urea 2%, basic rhodamine 0.5%, add water to make up to 100%. After mixing, grind in a sand mill for 3 to 4 hours, so that the particle size is all below 5 μm.

Embodiment 2

[0028] Embodiment 2: 15% dinotefuran · difenoconazole suspension seed coating

[0029] Each component content (by weight) is: dinotefuran former medicine 10%, difenoconazole former medicine 5%, agricultural milk 6022%, phosphoric acid ester (YUS-FS3000) 4% and polycarboxylate ( YUS-WG5) 2%, hydroquinone 2%, xanthan gum 0.5%, silicone oil 1%, urea 2%, basic rhodamine 0.5%, add water to make up to 100%. After mixing, grind in a sand mill for 3 to 4 hours, so that the particle size is all below 5 μm.

Embodiment 3

[0030] Example 3: 25% dinotefuran difenoconazole suspension seed coating

[0031] The content of each component (by weight) is: dinotefuran technical 15%, difenoconazole technical 10%, agricultural milk 6022%, sodium dodecylsulfonate 10%, quinone 2%, Carboxymethylcellulose 3%, n-octanol 1%, ethylene glycol 2%, basic rhodamine 0.5%, add water to make up to 100%. After mixing, grind in a sand mill for 3 to 4 hours, so that the particle size is all below 5 μm.

Abstract

The invention discloses a suspension seed coating agent prepared with a dinotefuran and difenoconazole compound as active ingredients and with addition of other auxiliary materials. The preparation has the characteristics of high suspension rate, good film-forming performance, uniform seed coatings, high efficiency and low toxicity and the like. While in use, the suspension seed coating agent has good utilization rate, can reduce the amount of drug agents, and effectively reduces environmental pollutions. Compared with a dinotefuran single agent and a difenoconazole single agent, the suspension seed coating agent allows prevention and curing effects of diseases and pests to be significantly improved and has compatible curing effect, and besides, has the effect of promoting seed germination. The suspension seed coating agent is applicable to treatment of seeds of rice, wheat, corn, soybean, peanut and other crops, can be not only mechanically operated but also artificially dressed the seeds during seed treatment, and can meet the needs of different production levels.

Description

technical field [0001] The invention relates to a suspension seed coating agent which takes dinotefuran and difenoconazole as active ingredients and belongs to the field of pesticides. Background technique [0002] Dinotefuran (dinotefuran) is a nicotinic acetylcholine receptor inhibitor, which mainly acts on synapses in the central nervous system of insects. It is mainly contact killing and stomach poisoning to pests and has systemic activity. After application, the plant absorbs and distributes to the top , suitable for the control of piercing-sucking mouthparts pests, with quick-acting, high-efficiency and long-lasting characteristics, mainly used to control thrips, planthoppers, leafhoppers, aphids on rice, wheat, corn, soybeans, peanuts and other crops , whiteflies and their resistant strains, and have efficient killing effects on Coleoptera, Diptera, Lepidoptera, Diptera, Beetles and Homoptera and other pests. Currently, such preparations are powders. [0003] Difenoc...
