[0056]

Embodiment 18～35

[0057] Embodiment 18~35 water dispersible granules

[0058] Combine pyraclostrobin, active ingredient B, dispersant, wetting agent, binder (optional), disintegrant, and filler through airflow pulverization 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 invention discloses a sterilization composition containing ametoctradin and thiocarbamates. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from ametoctradin; the active ingredient B is selected from any one of compounds as follows: mancozeb, propineb, zineb and methyram; the weight ratio of the active ingredient A to the active ingredient B is (1: 80) to (60: 1). The composition has relatively high activity on various diseases on various crops, has a remarkable synergistic effect, expands the bacteriocidal spectrum, and has the characteristics of low dosage and rainwash resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing pyraclostrobin and thiocarbamate to crop diseases. technical background [0002] Ametoctradin chemical name: 5-Ethyl-6-octyl[1,2,4]triazolo[1,5-a]pyrimidin-7-amine, Ametoctradin class of fungicides. Inhibitor of mitochondrial respiration, acts on complex III inhibition. [0003] Mancozeb, Prozeb, Zinc and Mancozeb are some common broad-spectrum fungicides, which are effective against various diseases of fruit trees, vegetables and other crops, and are widely used in agriculture. Among them, mancozeb is often mixed with systemic fungicides to delay the emergence of resistance. Propineb contains zinc elements that are easily absorbed by crops, which is beneficial to promote crop growth and improve fruit quality. Mancozeb has Strong contact action, Daisenlian has a good control effect on various diseases caused by Oomycete f...
