Technical Field

The invention relates to the technical field of pesticides, and particularly relates to a microcapsule suspending agent for preventing and treating red pine tip mottled borer and application thereof.

Background

Korean pine is the main tree species of mixed forest with needle leaves and broad leaves in cold and warm areas, and is a precious wood. In recent years, the development of the Korean pine industry and the growth of forests are seriously influenced by Korean pine tree pests. With the increase of the planting area of the red pine and the interference of the red pine cone pinworm disease, the damage to the cones and the twigs of the red pine is more and more serious. The damage rate of cones and twigs of the Korean pine can reach about 40 percent, the seed loss rate can reach 25 percent, and the method has serious threat to forest ecological environment and forestry economic development. The fruit tip spotted borer (Diorytriaphyrii Ragonit) belongs to the family of Lepidoptera (Lepidotera) borer (Pyralidae), is a borer and also an important pest damaging the fruit of Pinus Koraiensis (Pinus Koraiensis). In recent years, the method is applied to seed gardens of Korean pine, natural Korean pine mother forests and artificial Korean pine forests. The worm damages the cones and young shoots of the Korean pine by boring with larvae, and the cones are bent and deformed, dried and withered when damaged, thereby affecting the yield and quality of seeds and causing economic loss; the growth of the tree is inhibited after the tender tips are damaged, and the normal growth of the tree is influenced.

At present, organophosphorus and organochlorine pesticides with high toxicity and pyrethroid pesticides with high toxicity to beneficial insects and birds are generally adopted in China for prevention and treatment, but because of the boring property of the fruit tip spotted borer and the long hazard period of the fruit tip spotted borer, the pesticide and the prevention and treatment method are difficult to control the generation of the fruit tip spotted borer. Due to repeated application, not only the drug resistance is generated, but also the ecological environment is destroyed.

In recent years, new insecticides such as emamectin benzoate, deltamethrin, matrine, chlorbenzuron, abamectin and the like are continuously developed, but the insecticides also have the problems of insecticide resistance and poor pesticide effect after being singly used for a long time, and the current pesticide requirements for preventing and controlling the fruit tip striped rice borer are difficult to meet. Therefore, the development of a novel pesticide for effectively controlling the red pine tip striped rice borer is urgently needed.
