Abstract

The invention discloses a biopesticide suitable for cucumber downy mildew and a preparation method thereof. By aiming at the characteristic of cucumber downy mildew and the mechanism of action of various biological agents and herbal medicine extracts, biological agents like maltophilia, catechinic acid, bacillus subtilis, kasugamycin, a licorice extract, a xanthium sibiricum extract and a solanum nigrum extract which have different efficacies and characteristics are compounded through reasonable screening. The invention further discloses an effective preparation method, the prepared biopesticide not only has a good action effect on cucumber downy mildew, but also can effectively avoid the reduction of output of cucumbers, is non-toxic, harmless, ecological and environment-friendly, can greatly reduce the dosage, pesticide application times and the cost of the biopesticide, and besides, the biopesticide is convenient in preparation, long in storage time and has a strong practical value.

Description

technical field [0001] The invention relates to cucumber planting techniques, in particular to a biological pesticide suitable for cucumber downy mildew and a preparation method thereof. Background technique [0002] Cucumber downy mildew is one of the important diseases in the process of cucumber planting. It occurs in more than 70 countries in the world. Prevention and control is more difficult. Since the 1990s, the scale of vegetable production has been increasing day by day, and its occurrence and damage have been increasing year by year, resulting in a substantial reduction in cucumber production and seriously threatening farmers' crop income. [0003] At present, chemical agents are still one of the most effective measures to prevent and control cucumber downy mildew. However, with the long-term use of a large number of systemic fungicides, some fungicide varieties have successively developed resistance, and frequent control times have caused pesticide residues to exce...
