Ointment for preventing and treating insect pest longicorn of poplar

Abstract

The invention discloses an ointment for preventing and treating insect pest longicorn of a poplar, belonging to the field of pesticide and preparation thereof. The ointment is prepared from the following raw materials by weight percent: 1-10% of Chlorantraniliprole, 1-50% of dichlorvos and the balance of an addition agent. The bark on the trunk of the poplar, with perpendicular distance of 0.3-1.8m from the root of the poplar, is cut off from top to bottom in a spiral ring manner, so as to form a spiral groove, the width of the spiral groove is 2-20cm, the depth of the spiral groove is the distance between the surface of the poplar to the phloem thereof, and the ointment is uniformly spread in the spiral groove. The ointment spread on the part of which the bark is peeled, on the trunk can be absorbed inside through the plant, thus having good adhesive force and long effect, and the ointment is convenient and simple to apply, improves the use ratio, lowers the environment pollution, has certain touch out action, and can prevent pests from creeping on the trunk up and down, thus greatly relieving the harm of the pests to the plant.

Description

technical field [0001] The invention relates to an ointment for preventing and controlling poplar beetle pests, and belongs to the field of pesticides and preparations thereof. Background technique [0002] Poplar longhorn beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. More than 100 species of poplar longhorn beetle have been reported in China. Due to the hidden life of poplar longhorn beetles, few types of natural enemies, and complex life history, poplar is one of the preferred tree species for afforestation in my country, such as afforestation, windbreak and sand fixation, fast growth and high yield, resulting in sufficient food resources for poplar longhorn beetles. The occurrence area is 600,000 hm 2 about. In the past 10 years, the macular beetle and bald beetle have spread rapidly and caused serious damage, which has greatly restricted the development of poplar and seriously affected the healthy development of fo...

Problems solved by technology

[0007] The difficulty faced by the above methods is that the biological control effect is not stable, and the control effect is affected by factors such as weather. Drugs, sprays and other methods, but these methods encounter great difficulties in the control effect or specific implementation operations

The poison swab method needs to find the holes of longhorn beetle larvae and adults, and the workload is too large for large-scale control; the workload of drilling and injection is too large for large-scale control, and the xylem of poplar is damaged after drilling. The self-healing ability is limited, and most of them will be rotted. Farmers have certain difficulties in accepting this method; when spraying, the dosage is large, and the droplets will drift with the wind. High-pressure spraying machinery is required, and the medicine is also difficult. Effectively reach the worm body, the utilization rate of the medicine is too low
