Embodiment 1~18

[0041] Embodiment 1~18 wettable powder

[0042] The wettable powder product of the present invention can be produced by mixing imidaclofen, active ingredient B, dispersant, wetting agent and filler, mixing uniformly in a mixing tank, pulverizing with a jet mill and then mixing uniformly. See Table 1 for details.

[0043] Table 1 The components and contents of Examples 1 to 18

[0044]

Embodiment 19~33

[0045] Embodiment 19~33 water dispersible granules

[0046] Combine imidazolidin, active ingredient B, dispersant, wetting agent, disintegrating agent, binder (optional), and filler through airflow milling to obtain the required particle size and obtain the granulation material. 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 present invention discloses a fenamidone-containing sterilization composition, which comprises an active component A and an active component B, wherein the active component A is selected from fenamidone, the active component B is any one compound selected from propamocarb or a salt thereof, cymoxanil, chlorothalonil, captan and iprovalicarb, and a weight ratio of the active component A to the active component B is 1:80-60:1. The composition provides high activities for a plurality of plant diseases of a plurality of crops, and has characteristics of significant synergistic effect, bacterial killing spectrum expanding, low use amount, rainfall erosion resistance, and significant synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a 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] Propamocarb (Propamocarb) chemical name: 3-(dimethylamino) propyl carbamate, molecular formula: C 9 h 21 N 2 o 2 Cl. The salt of propamocarb can be propamocarb hydrochloride (Propamocarb hydrochloride), chemical name: propyl-3-(dimethylamino)propyl carbamate hydrochloride. Both propamocarb and its salts have local systemic effect, and can also be used as impregnation treatment ...
