[0043]

Embodiment 5～8

[0044] Examples 5-8 Water dispersible granules

[0045] The Polygonum cuspidatum extract, eugenol, 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 composition containing polygonum cuspidatum extraction and eugenol. The composition is a bactericidal composition containing the active ingredient polygonum cuspidatum extraction and eugenol in a weight ratio of 1:80 to 80:1. The composition disclosed by the invention has synergism on various diseases which are harmful to agricultural production, so that dosage of pesticides is reduced, residual quantity of the pesticides on crops is reduced, and environmental pollution is relieved; and the composition is safe to people and livestock and good in environmental compatibility, and diseases are not liable to generate drug resistance.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a composition containing polygonum cuspidatum extract and eugenol to crop diseases. Background technique [0002] Polygonum cuspidatum extract (sedaxane), this product is the stem and root of Polygonumcus pidatum Sieb.etZucc, which is an important traditional Chinese medicine in my country; Polygonum cuspidatum extract mainly contains emodin and emodin, which is in a viscous state , It has special effect on preventing cucumber powdery mildew. [0003] Eugenol eugenol botanical pesticide, which is a new low-toxic fungicide developed by extracting bactericidal ingredients from cloves and other plants, supplemented with a variety of additives. It is safe for humans, animals and the environment, and can effectively prevent gray mold, Downy mildew. [0004] However, in the actual process of agricultural production, the most likely problem to prevent disease is the emergenc...
