Plaster for preventing forestry pests poplar longicorn

Abstract

The invention discloses a plaster for preventing forestry pests poplar longicorn and relates to the field of pesticide and preparations thereof. A plaster for preventing poplar longicorn is prepared from the following raw materials in percentage by weight: 1-10% of chlorantraniliprole and 1-50% of acephate, and the remaining is assistant. The poplar bark is removed by spiral ringing from top to bottom on a poplar trunk with the vertical distance of 0.3-1.8m from the root to form a spiral groove which is 2-20cm in width. The depth of the spiral groove is from the poplar surface to a phloem thereof. The plaster is uniformly coated at the spiral groove. By being coated at the peeled bark, the plaster provided by the invention is good in adhesive force and persistence, simply and conveniently applied, thereby improving the medicament utilization ratio and reducing the environmental pollution. As the medicament can be sucked into plants through epidermis and the plaster provided by the invention has certain contact action, the pests can be prevented from crawling up and down on the trunk so as to greatly reduce harm to the plants.

Description

technical field [0001] The invention relates to an ointment for preventing and controlling forestry pest poplar beetle, 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 developme...

Problems solved by technology

[0007] 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 poplar longicorn beetle is a kind of boring pest, and biological control agents are difficult to reach the adults and larvae of longicorn beetle; 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

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
