Embodiment 1

[0034] Example 1: Preparation of 20% trifluoropyrim-metconazole seed treatment suspension

[0035] The specific formula is: trifluoropyrimidine 15%, metconazole 5%, polymer of polyvinyl acetate and polyvinyl alcohol 5%, polyvinyl alcohol 5%, basic rhodamine 5%, magnesium aluminum silicate 1% , 1% ethylene glycol, 0.5% potassium benzoate, 0.5% organic ketones, and make up the balance with distilled water.

[0036] The specific preparation method is as follows: mix the above-mentioned components in proportion, stir them evenly, put them into a sand mill and grind them for 3-4 hours, and the particle size can be obtained after testing if the diameter is below 5 μm.

Embodiment 2

[0037] Embodiment 2: Preparation of 15% trifluoropyrim-metconazole seed treatment suspension

Abstract

The invention discloses a pesticide composition containing trifluorobenzene pyrimidine and a preparation method and application thereof. Effective components of the composition disclosed by the invention comprise the trifluoro-benzene pyrimidine and the metconazole. A seed treatment suspending agent prepared from the composition can effectively control rice bakanae disease through one-time seed treatment; harm of rice planthoppers in the early stage and the middle stage of rice can be effectively controlled through one-time seed treatment; and the method obviously reduces the use amount and use frequency of pesticides, reduces environmental pollution and agricultural product residues, effectively saves field labor cost, and can be widely applied to the field of rice seed treatment.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemicals, and in particular relates to a pesticide composition containing trifluoropyrimidine, a preparation method and an application. Background technique [0002] In modern agricultural production, using seed treatment agents to treat seeds is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. Compared with conventional spraying, dusting and soil treatment, seed treatment technology is the most economical and effective method in the control of plant diseases and insect pests. Seed treatment can not only reduce the amount of pesticide use, but also reduce the frequency of pesticide use during the crop growth period. [0003] As we all know, rice plant diseases and insect pests during the growing season are the main threats to the safe production of rice, and rice planthopper and rice bakanae are the main ...
