Embodiment 17~32

[0052] Embodiment 17~32 water dispersible granules

[0053] Combine imidazolidin, active ingredient B, dispersant, wetting agent, disintegrating agent, and filler through airflow pulverization to obtain the required particle size, and then add binder (optional) and other additives to obtain granulation Materials. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

Abstract

The invention discloses an efficient bactericidal composition comprising fenamidone, the efficient bactericidal composition comprises an active component A and an active component B, the active component A is selected from the fenamidone, the active component B is selected from any of the following compounds: cyprodinil, pyrimethanil, diethofencarb, iprodione or procymidone, and the weight ratio of the active component A to the active component B is 1:80-60:1. The bactericidal composition of the invention has high activity against a variety of diseases of various crops, has an obvious synergistic effect and an expanded bactericidal spectrum, and has the characteristics of small drug use amount, rain drop erosion resistance and obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency bactericidal composition containing imidazolidin on crop diseases. technical background [0002] Fenamidone molecular formula: C 17 h 17 N 3 OS, chemical names: (S)-1-anilino-4-methyl-2-methylthio-4-phenylimidazolidin-5-one, imidazolidin and oxaflumedone and methoxyacrylate The mechanism of action of fungicides is similar, inhibiting liner respiration by blocking electron transfer at the hydrogenation enzyme Q-cytochrome C radon level. (R)-enantiomer is much higher. [0003] Cyprodinil chemical name: 4-cyclopropyl-6-methyl-N-phenylpyrimidin-2-amine, molecular formula: C 14 h 15 N 3 . It can inhibit the biosynthesis of methionine and inhibit the secretion of hydrolase. Absorbed quickly by leaves in plants, more than 30% penetrates into tissues, the protected sediment is stored in leaves, transported in xylem, and also transported betw...
