Biological pesticide

Abstract

The invention relates to the field of preventing and controlling agricultural pests, in particular to a biological pesticide which has the functions of killing pests and fertilizing and is used for killing great cloudy scarab beetles, so as to solve the problems of causing harm to the environment and the human body health because the existing process of preventing and controlling the great cloudy scarab beetles depends on highly toxic pesticides excessively. A processing method comprises the following steps: any part of a castor-oil plant is taken as a raw material and is ground into powder as well as is filtered through a fine screen with 50-60 meshes, and 1-3.5% of zinc, 0.2-0.4% of boron, 0.2-0.4% of molybdenum, 2-2.7% of manganese, 0.3-1% of iron, 0.3-3% of copper and 0.3-3% of sulfur which are weighed according to the mass of the castor-oil plant are added to be taken as potentiating agents and are mixed evenly. In the process of preventing and controlling the great cloudy scarab beetles, the biological pesticide provided by the invention can eliminate the highly toxic pesticides, reduce the repeated investment of manpower, material resources and financial resources, facilitate energy conservation, recycling, environment protection and utilization of renewable resources, and meet new requirements of saving energy, recycling and protecting the environment.

Description

technical field [0001] The invention relates to the field of prevention and control of agricultural diseases and insect pests, in particular to a biopesticide which can kill the beetle of the giant cloud spot and has the functions of killing insects and fertilizers. Background technique [0002] The large cloud-spotted beetle beetle (larvae have another name called grub), was originally a subterranean pest that harmed forest and fruit trees. Since the 1980s, the scope of damage has shifted and expanded. The crops that are endangered in agricultural production include cereals, vegetables, beans and other crops, as well as seedlings, etc. The food habits are very mixed, and it has become a rare hazard range. Widespread and serious underground pests. The population density of the damaged plots of the large cloud spot beetle is more than 2 larvae per square meter on average, more than 11 larvae per square meter in serious plots, and more than 25 larvae per square meter in sever...
