Abstract

The invention discloses a density-board-based slow-release biological prevention and control agent which is prepared from density boards and entomogenous fungus spore powder. The invention further provides a preparing method for the density-board-based slow-release biological prevention and control agent. The method comprises the following steps that 1, when the laying working procedure is carried out on the density boards, the entomogenous fungus spore powder is uniformly placed between the two boards, then hot-pressing treatment is carried out, cooling is carried out to the room temperature to obtain a material a; 2, the surface of the material a obtained in the step 1 is smeared with a color to obtain a material b; 3, the material b obtained in the step 2 is cut into blocks to obtain the density-board-based biological prevention and control agent. The invention further provides application of the density-board-based slow-release biological prevention and control agent. The density boards are adopted as external wrapping materials, the stability of the spore powder in the biological prevention and control agent manufacturing and application processes is ensured, the spore powder is released slowly, and then persistence of the biological prevention and control effect is ensured; the slow-release biological prevention and control agent is remarkable in effect, low in cost, clean in process, economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of biological control agents, in particular to a density board-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 prevent...
