Abstract

The invention discloses a wax paper based sustain-released bio-control agent, which comprises the following raw materials: waste and old wax paper, entomogenous fungus spore powder, and an adhesive. The invention also discloses a preparation method of the sustain-released bio-control agent. The preparation method comprises the following steps: step one, grinding waste and old wax paper into fragments with a particle size of 2 to 4 mm, and then evenly mixing the fragments with inoculated fungus spore powder to obtain a material (a); step two, using an adhesive agent to artificially make the material (a) into granular materials; step three, painting pigment on the surface of the granular materials so as to obtain the sustain-released bio-control agent. The invention also discloses applications of the sustain-released bio-control agent. The bio-control agent can be evenly sprayed on farmland or forest through different modes: artificial spraying, mechanical spraying, display shell spraying, aviation spraying, and the like. The preparation method has the advantages that various biodegradable solid wastes are converted into valuable resources, the spore powder can be slowly released, and thus the bio-control effect can last for a long time.

Description

technical field [0001] The invention relates to the technical field of biological control of plant diseases, in particular to a wax paper-based slow-release biological control agent and its preparation method and application. Background technique [0002] Crop and plant diseases and insect pests can cause symptoms such as discoloration, necrosis, deformity, wilting, perforation, and early fall of plant leaves, which seriously restrict the high, stable and high-quality yield of crops, economic crops, and medicinal plants. Currently, the commonly used control technologies mainly include The chemical control method and the increasingly mature biological control method in recent years, but as people's voice for pollution-free and pollution-free green food is increasing, the chemical control method cannot be used due to the accumulation of pesticides, environmental pollution, and harm to the human body. To meet people's health requirements, biological control mainly realizes the ...
