[0039]

Embodiment 9～16

[0040] Examples 9-16 Water dispersible granules

[0041] The Polygonum cuspidatum extract, active ingredient B, dispersant, wetting agent, disintegrant, filler, etc. are crushed together to obtain the required particle size, and then other additives such as binder (with or without addition) are added to obtain granulation Materials. After the material is quantitatively fed into the fluidized bed granulating dryer and granulated and dried, the water-dispersible granule product of the present invention can be prepared, as shown in Table 2.

Abstract

The invention discloses a bactericidal composition containing giant knotweed extract and ZJ0712 or pyraoxystrobin. The bactericidal composition comprises an active component A and an active component B, wherein the active component A is giant knotweed extract, the active component B is any compound selected from the group consisting of ZJ0712 and pyraoxystrobin, and a weight ratio of the active component A to the active component B is 1: 80 to 60: 1. The bactericidal composition provided by the invention exerts a synergistic effect on a plurality of diseases harming agricultural production, reduces the dosage of pesticides, decreases the residual quantity of pesticides on crops, mitigates environmental pollution, is safe to human beings and livestock, has good environmental compatibility and enables diseases not to easily generate resistance.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a bactericidal composition containing Polygonum cuspidatum extract and fenoxystrobin or pyraclostrobin on crop diseases. Background technique [0002] Polygonum cuspidatum extract mainly contains emodin and emodin methyl ether. It is in a viscous state and is generally easy to be made into liquid preparations. However, liquid preparations usually contain organic solvents and are prone to phytotoxicity and can be used to prevent and control cucumber powdery mildew. [0003] Diphenoxystrobin and pyraclostrobin are both methoxy acrylate fungicides and are widely used in crop diseases. [0004] However, in the actual process of agricultural production, the most likely problem to prevent disease is the emergence of disease resistance. The compounding of ingredients of different varieties is a very common method to prevent and control resistant diseases. Different ingredie...
