Problems solved by technology

[0002] The existing preparations for preventing and controlling subterranean pests are processed into microcapsule suspensions for spraying by adding capsule wall materials and emulsifying dispersants, and then combined into capsules and ripening. They are mainly used for preventing and controlling Lepidoptera pests; When coating agent, slag and seed surface roughness will appear, which is not conducive to the efficacy of the drug and mechanical sowing

Embodiment Construction

[0020] Put 10-60% by weight (example 10%, 35%, 60%) of chlorpyrifos technical, 1-20% by weight (example 1%, 10%, 20%) 500# solvent oil, 1-10% (example 1 %, 5%, 10%) by weight capsule wall material and 1-1.5% by weight (example 1%, 1.2%, 1.5%) emulsifier, 1-3% by weight (example 1%, 2%, 3%) film-forming The agent is configured as an oil phase; water (remainder), 1-3% weight dispersant (eg 1%, 2%, 3%) is configured as a water phase, and the oil phase is added to the water phase under the condition that the homogenizer is opened After the emulsion is made into an emulsion; finally, the emulsion is transferred to the aging tank and stirred for aging, and 0-0.2% by weight (for example, 0%, 0.1%, 0.2%) of an organic silicon defoamer is added during the aging process, and the aging reaction is completed get the product. The sum of the amounts of the above-mentioned components is 100%.

[0021] The capsule wall material is polymethylene polyphenylisocyanate. The film-forming agent ...

Abstract

The invention discloses a chlorpyrifos microcapsule suspension seed coating agent for controlling underground pests and a preparation method thereof. The chlorpyrifos microcapsule suspension seed coating agent comprises chlorpyrifos technical, solvent oil No.500, a capsule wall material, an emulsifying agent, a film forming agent, a dispersant, an organic silicon defoaming agent and water. The chlorpyrifos microcapsule suspension seed coating agent can release active ingredients slowly, so that the duration of the pesticide effect is effectively prolonged, the safety of the pesticide agent is increased at the same time, and particularly, an obvious effect of controlling the underground pests is achieved. The chlorpyrifos microcapsule suspension seed coating agent has seed coating film-forming property, and can uniformly coat chlorpyrifos microcapsules on the surface of a seed so as to protect the seed effectively and prevent the seed from being damaged by the underground pests.

Description

technical field [0001] The invention relates to a preparation method of a chlorpyrifos microcapsule suspension seed coating agent for preventing and controlling underground pests. Background technique [0002] The existing preparations for preventing and controlling subterranean pests are processed into microcapsule suspensions for spraying by adding capsule wall materials and emulsifying dispersants, and then combined into capsules and ripening. They are mainly used for preventing and controlling Lepidoptera pests; Phenomena such as slag dropping and seed surface roughness occur during coating, which is not conducive to drug efficacy and mechanical sowing. Contents of the invention [0003] The object of the present invention is to provide a chlorpyrifos microcapsule suspension seed coating agent for controlling underground pests, which can release active ingredients slowly, increase the duration of drug effect and drug safety, and its preparation method. [0004] Techni...
