Fungicide for controlling willow pests and preparation method of fungicide

Abstract

The invention relates to a fungicide for controlling willow pests. The fungicide comprises aconite, Chinese prickly ash, fructus cinnamomi, tripterygium wilfordii, atractylodes, radix euphorbiae lantu, viola, eucommia ulmoides, quispualis indica and semen cassia. The method comprises the following steps: weighing various components according to the amount; respectively adding water and decocting, extracting effective components, cooling, and then merging an extract liquid; adding realgar and chalcanthite under a micro-heating condition; and stirring evenly to prepare a finished product. The effective components of the traditional Chinese medicines in the fungicide are matched with one another, so that willow pests such as long-horned beetle, clania variegata snellen and cleoporus varriabilis can be effectively prevented and treated; the death knockdown rate within 3 days after the fungicide is sprayed is over 93%; the willow surrounding environment is free of an obvious peculiar smell; birds are not poisoned; the environment is not polluted; and the physical health of people is not harmed.

Description

technical field [0001] The invention belongs to the technical field of willow insect pest control, in particular to a willow insect pest control agent. Background technique [0002] Willow is a large deciduous tree with slender, soft and drooping branches. It likes wetlands and grows rapidly. It can reach a height of 20-30 meters and a diameter of 50-60 centimeters. It is a native tree species in my country. It is resistant to air pollution and dust. Strong, when in full bloom, the branches spread to all directions of the willow tree, which has high ornamental value, and is often used for garden viewing, residential areas, schools, factories, hillsides, courtyards, roadsides, and in front of buildings. In the process of planting willows, in addition to scientific management of water and fertilizer, pest control and deworming must also be done. Pests and diseases that injure willow trees include star-boring longhorn beetles and bald-shouldered longhorn beetles that eat branch...

AI Technical Summary

Problems solved by technology

Pests and diseases that injure willows include star-boring beetles and bald-shouldered longhorns that eat branches and leaves, giant moths that damage branches and leaves, plum leaf beetles, willow leaf beetles, grasshoppers, etc., and green-tailed silkworm moths that attack leaves. These pests harm different parts of willow trees. In addition, dilute solutions such as trichlorfon and phoxim are traditionally used for prevention and control. However, the extensive use of chemical agents will not only increase the resistance of pests, but also pollute the surrounding environment, which is also a threat to birds and beneficial insects.
