Abstract

The invention relates to the technical field of pesticide for controlling rice sheath blight diseases and false smut, in particular to a suspending agent of thifluzamide and tebuconazole composite pesticide and a preparation method of the suspending agent. The suspending agent is prepared by the following ingredients in parts by weight: 20 parts of thifluzamide, 32 parts of tebuconazole, 18 parts of emolsifier and 30 parts of solvent. The prepared suspending agent is obviously superior to products prepared according to other proportions in suspensibility, persistent foamability, wet sieving test, thermal stability and the like. Experiments verify that the cotoxicity coefficient of the suspending agent reaches 154.19, the suspending agent falls in an obvious synergistic action scope, and preparations mixed in other proportions cannot reach the obvious synergistic action scope. In addition, the actual toxicity of different proportions is not raised with theoretical toxicity, and no change law exists between the actual toxicity and the theoretical toxicity. The suspending agent of the thifluzamide and tebuconazole composite pesticide is suitable for controlling the rice sheath blight diseases and the false smut, and has good popularization and application values.

Description

technical field

[0001] The invention relates to the technical field of pesticides for the prevention and treatment of rice sheath blight and rice false smut, in particular to a suspending agent of a compound pesticide of thifuramide and tebuconazole and a preparation method thereof. Background technique

[0002] At present, the existing pesticides used to prevent and control rice sheath blight and rice false smut, for example, Chinese patent "CN102630680 A" discloses a "fungicide composition with synergistic effect and its preparation method", wherein thiofluxamide The weight ratio to tebuconazole is 15-40%: 3-30%, and it can be made into various dosage forms suitable for spraying. At the same time, the preferred weight ratio of thiafuramide and tebuconazole in the pesticide composition is 5:1, so that the synergistic effect can be optimized.

[0003] The inventor has verified through long-term experiments that the pesticide composition has the following defects:

[0004] ...
