A kind of ointment for preventing and treating longicorns with systemic conduction and its application method

Abstract

The invention discloses an ointment for preventing and treating longicorns with systemic conduction function, which belongs to the field of pesticides and preparations thereof, and is prepared by mixing trifluoropyrim, quinthion and auxiliary agents, wherein trifluoropyrim, quinthio The percentage by weight of phosphorus accounting for the total weight of the ointment is 0.1-20%, 0.1-20%, and the rest are auxiliary agents. The auxiliaries include solvents, adhesives and fillers, wherein the weight percentages of the solvents, adhesives and fillers in the total weight of the ointment are 0.1-80.0%, 0.1-80.0%, and 0.1-80.0%, respectively. The invention also discloses a method for using the above-mentioned ointment: the ointment of the invention is applied to the peeled bark, which has good adhesion and long-lasting effect, is easy to apply, improves the utilization rate of the medicament, and reduces environmental pollution. The ointment can be sucked into the plant through the plant epidermis, and the ointment of the invention has a certain contact killing effect, which can prevent pests from crawling up and down the trunk, thereby greatly reducing the damage to the plant.

Description

technical field [0001] The invention relates to an ointment for preventing and treating longicorn beetle with systemic conduction function and a using method thereof, and belongs to the field of pesticides and preparations thereof. Background technique [0002] Beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. There are more than 100 kinds of beetles reported in China. Due to the secluded life of longicorn beetles, few types of natural enemies, and complex life history, poplar and willow are 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 longicorn beetles and serious harm to longicorn beetles in my country. , with an annual area of ​​600,000 hm 2 about. In the past 10 years, the macular beetle and the bare-shouldered beetle have spread rapidly and caused serious damage, which has gr...

Problems solved by technology

(2) The generational differentiation of longhorn beetles is relatively complicated, and the general generation is long, with a life cycle of more than one year. Due to the huge differences in the niches in which individuals live, their life history is changeable and complicated, which has caused great harm to the control work of longhorn beetles. great difficulty

[0004] The difficult problem that above each method faces is that the biological control effect is unstable, and the control effect is affected by factors such as weather, and longicorn beetle is a kind of boring pest, and biological control agent is difficult to reach the adult and larva of longicorn longicorn; Chemical control methods are used in large areas, such as poison swabs, drilling injections, burying drugs, spraying, etc., but these methods encounter great difficulties in the control effect or specific implementation

When spraying, the amount of medicine is large, and the droplets will drift with the wind. It is necessary to use high-pressure spraying machinery, and it is difficult for the medicine to reach the insect body effectively, and the utilization rate of the medicine is too low

The poison swab method needs to find the openings 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 the tree is damaged after drilling, and the self-healing of the tree The capacity is limited, and most of them will be rotten. Farmers have certain difficulties in accepting this method
