Problems solved by technology

[0002] In the compound seed coating agents currently on the market for seed coating, the active ingredients that play an insecticidal role are mostly highly toxic pesticides such as carbofuran and phorate, which bring many safety hazards to farmers. It has a serious impact on the environment and cannot meet the needs of modern agricultural development.
At the same time, in the compound seed coating agents currently on the market for preventing and treating corn head smut, most of the active ingredients that play a bactericidal role are single fungicides, and the bactericidal effect is not ideal.

Embodiment 1

[0018] Mix 10kg of thiram, 0.5kg of tebuconazole, 1kg of bentonite, 1kg of emulsifier and 75kg of water for 1 hour and stir evenly. Send the above-mentioned homogeneous mixed solution into a horizontal sand mill for grinding in series by three sets, and grind for 2-3 hours to obtain the mixed solution after grinding. Put the ground mixed solution into a blending kettle, add 5 kg of carbosulfan, 5 kg of film-forming agent, 1 kg of thickener, 1 kg of antifreeze and 0.3 kg of rhodamine in sequence, and mix and blend for 2-3 hours to prepare Obtain seed coating agent of the present invention.

Embodiment 2

[0020] Mix 12kg of thiram, 0.7kg of tebuconazole, 3kg of bentonite, 3kg of emulsifier and 60kg of water for 1 hour, and stir evenly. Send the above-mentioned homogeneous mixed solution into a horizontal sand mill for grinding in series by three sets, and grind for 2-3 hours to obtain the mixed solution after grinding. Put the ground mixed solution into a blending kettle, add 7kg of carbosulfan, 8kg of film-forming agent, 3kg of thickener, 3kg of antifreeze and 0.6kg of rhodamine in sequence, and mix and blend for 2-3 hours to prepare Obtain seed coating agent of the present invention.

Embodiment 3

Abstract

The invention discloses compound seed coating agent and the preparation method thereof. The compound seed coating agent is manufactured with 5 to 10 kg of carbosulfan, 10 to 15kg of fernasan, 0.4 to 1kg of tebuconazole, 5 to 10kg of film former, 1 to 5kg of bentonite, 1 to 5kg of thickener, 1 to 5kg of emulsifier, 0.2 to 1kg of rhodamine, 1 to 5kg of antifreeze and 40 to 80kg of water. The invention has the characteristics of high efficiency and low toxicity. The toxicity of the invention is 20 to 30 times lower than that of the seed coating agent made from the carbofuran and thimet etc.; due to the mixture of the fernasan and tebuconazole, the sterilizing effect of the seed coating agent on the head smut in maize is 8 times higher than that of the single bactericide.

Description

technical field [0001] The invention relates to a new pesticide dosage form, in particular to a compound seed coating agent and a preparation method thereof. Background technique [0002] In the compound seed coating agents currently on the market for seed coating, the active ingredients that play an insecticidal role are mostly highly toxic pesticides such as carbofuran and phorate, which bring many safety hazards to farmers. It has a serious impact on the environment and cannot meet the needs of modern agricultural development. At the same time, in the compound seed coating agents currently on the market for preventing and treating corn head smut, most of the active ingredients that play a bactericidal role are single fungicides, and the bactericidal effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide a new type of seed coating product with high efficiency, low toxicity and remarkable effect of preventing and treatin...
