Embodiment 1

[0020] Firstly weigh each raw material according to the following weight percentage: 2% imidacloprid, 0.3% prochloraz, 3% emulsifier, 2% dispersant, 4% film former, 2% antifreeze, 0.2% thickener, 0.2% warning color , defoamer 0.1%, water 86.2%; then imidacloprid, prochloraz, emulsifier, dispersant, film former, antifreeze, thickener, warning color and water were dropped into sand mill and ground respectively for 1.5 hours; finally added The defoamer defoams, and after the defoaming is completed, the material is discharged, and the analysis is qualified and packaged.

[0021] When the ratio of pesticide to species is 1:30-80, the control effect on rice bakanae disease is above 77.7%, and the control effect on seedling pests is above 81.9%. The test results are shown in the following table. The above-mentioned formulations were used to test the inhibitory effect and toxicity of prochloraz and imidacloprid on the spore germination of Bakanae oryzae spore germination by using the ...

Embodiment 2

[0024] First weigh the raw materials according to the following weight percentages: 5% imidacloprid, 2% prochloraz, 5% emulsifier, 4% dispersant, 4% film former, 4% antifreeze, 0.2% thickener, 0.2% warning color , defoamer 0.1%, water 75.5%; then imidacloprid, prochloraz, emulsifier, dispersant, film former, antifreeze, thickener, warning color and water were dropped into sand mill and ground respectively for 2 hours; finally added The defoamer defoams, and after the defoaming is completed, the material is discharged, and the analysis is qualified and packaged.

[0025] When the ratio of pesticide to species is 1:30-80, the control effect on rice bakanae disease is over 80.5%, and the control effect on seedling pests is over 89.5%. The test results are shown in the table below. The above-mentioned formulations were used to test the inhibitory effect and toxicity of prochloraz and imidacloprid on the spore germination of Bakanae oryzae spore germination by using the PDA plate ...

Embodiment 3

[0028] Firstly weigh each raw material according to the following weight percentage: imidacloprid 10%, prochloraz 5%, emulsifier 5%, dispersant 5%, film former 8%, antifreeze agent 5%, thickener 3%, warning color 0.5% , defoamer 0.2%, water 58.3%; then imidacloprid, prochloraz, emulsifier, dispersant, film-forming agent, antifreeze, thickener, warning color and water were dropped into sand mill and ground respectively for 2.5 hours; finally added The defoamer defoams, and after the defoaming is completed, the material is discharged, and the analysis is qualified and packaged.

[0029] When the ratio of pesticide to species is 1:30-80, the control effect on rice bakanae disease is over 78.9%, and the control effect on seedling pests is 87.5%. The test results are shown in the table below. The above-mentioned formulations were used to test the inhibitory effect and toxicity of prochloraz and imidacloprid on the spore germination of Bakanae oryzae spore germination by using the ...

Its raw material composition includes (by wt%) 2-10% of imidaclopride, 0.3-5% of prochloraz, 3-5% of emulsifying agent, 2-5% of dispersion agent, 4-8% of film-forming agent, 2-5% of anti-freezing agent, 0.2-3% of thickening agent, 0.2-0.5% of assertive colours, 0.1-0.2% of defoaming agent and 58.3-86.2% of water. Said invention also provides the concrete operation steps of its preparation method.

Description

technical field [0001] The invention relates to a seed coating agent and a preparation method thereof, in particular to a suspension type rice seed coating agent mainly composed of imidacloprid and prochloraz and a preparation method thereof. Background technique: [0002] Imidacloprid is a nitromethylene systemic insecticide, which is the action body of the nicotinic acid acetylcholinesterase receptor, and is used to control piercing and sucking oral pests. It is effective against Coleoptera, Diptera and Lepidoptera. efficient. It is especially suitable for seed treatment; prochloraz is a broad-spectrum agricultural fungicide, which has obvious control effect on diseases caused by Ascomycetes and Deuteromycetes in various crops, and can also be used with most fungicides, insecticides, Mixed use of herbicides has good control effect. It can treat and eradicate various diseases on field crops, fruits and vegetables, turf and ornamental plants. The two kinds of medicaments ...
