Problems solved by technology

After research by the inventors, it was found that compounding the Polygonum cuspidatum extract with ethephon, paclobutrazol, uniconazole, naphthaleneacetic acid, dimethylglutaric acid, trinexapac-ethyl or mepiperium has a good increase in a certain range. However, there are no related reports about the compounding of Polygonum cuspidatum extract with ethephon, paclobutrazol, uniconazole, naphthaleneacetic acid, dimethylglutaric acid, trinexapac-ethyl or mepiperium

Abstract

The invention discloses a high-effective pesticide composition containing a polygonum cuspidatum extract. The composition includes an active component A and an active component B as effective active components, wherein the active component A is the polygonum cuspidatum extract, and the active component B is one selected from the following components: ethrel, paclobutrazol, uniconazole, naphthylacetic acid, dimethyl glutaric acid, trinexapac-ethyl or mepiquat chloride. The weight ratio of the active component A to the active component B is 1:300-500:1. The composition is high in activity in prevention and treatment of bacterial and fungal diseases of various crops, and also has the effects of stimulating root growth of crops, promoting growth of crops, increasing yield and improving crop quality.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a high-efficiency pesticide composition containing Polygonum cuspidatum extract on crop diseases. technical background [0002] Polygonum cuspidatum extract is a traditional Chinese medicine in my country. The 7th issue of "Pesticide" magazine in 2007 reported the effect of Polygonum cuspidatum extract and its isolated tissue on cucumber powdery mildew. and therapeutic effect. [0003] In the actual process of agricultural production, the most likely problem in disease control is the emergence of disease resistance. Combination of ingredients from different varieties is a common method for controlling resistant diseases. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases, the compounding effects of pesticides are additive effects...
