[0046]

[0047]

Embodiment 13～24

[0048] Embodiment 13~24 water dispersible granules

[0049] Kresastrobin, active ingredient B, dispersant, wetting agent, disintegrant, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain 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 invention discloses a bactericidal composition containing dimoxystrobin and imidazole, which contains an active component A and an active component B, wherein the active component A is selected from dimoxystrobin; the active component B is selected from any one of triflumizole, prochloraz or salt thereof, thiophanate-methyl and carbendazol; and the weight ratio of the active component A to the active component B is 1:80-60:1. The composition disclosed by the invention has higher activity for multiple diseases on multiple crops, has obvious synergistic action, widens the bactericidal spectrum, and has the characteristics of small dosage, rainfall erosion resistance and obvious synergistic action.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing kresastrobin and imidazoles on crop diseases. technical background [0002] Dimoxystrobin chemical name: (E)-2-(methoxyimino)-N-methyl-2[a-(2,5-dimethylphenoxy)-o-tolyl]acetamide , molecular formula: C 19 h 22 N 2 o 3 . It is an external quinone inhibitor, which acts on the cytochrome complex bc1 to hinder electron conduction to inhibit mitochondrial respiration. It has protective, therapeutic and conductive properties, and inhibits spore germination and hyphae growth. [0003] Salts of prochloraz include prochloraz manganese salt, prochloraz copper salt, and prochloraz zinc salt. [0004] Flufenazole, prochloraz or its salts, thiophanate-methyl, and carbendazim are all imidazole fungicides, which are common fungicides and are widely used in crop diseases. [0005] In the actual process of agricultural production, th...
