Abstract

The invention relates to a gel capable of preventing and treating decayed dry pests. The gel is prepared from the following components: 20-30g of an agent A, 40-60mL of an agent B, 10-20mL of an agentC, 30-50mL of an agent D, 1-1.5g of an agent E and water supplemented till the total volume reaches 1000mL, wherein the agent A is selected from one or several of xanthan gum, sodium alginate and locust bean gum; the agent B is selected from one of 1,3-propylene glycol or sorbitol; the agent C is absolute ethyl alcohol; the agent D is selected from one of 25% chlorbenzuron suspensoid, 1.2% nicotine sophocarpidine emulsion, 1% celastrus angulatu emulsion in water or 0.5% veratrine soluble liquid agent; the agent E is selected from one of 50% carbendazol wettable powder or 70% thiophanate-methyl wettable powder. The invention also relates to application of the gel to prevention and treatment of the decayed dry pests. The gel is excellent in effect of preventing and treating the decayed drypests, is non-toxic and tasteless, and is safe to natural enemies and environment of the decayed dry pests.

Description

technical field [0001] The invention relates to a gel for preventing and controlling dry borers and its application. Background technique [0002] Trunk borer pests mainly eat the trunk, branches and other parts of trees, and live secretly as larvae in the tree for a long time, causing the tree to be riddled with holes, destroying the transporting tissue, hindering the transportation of nutrients and water, causing poor growth, The leaves turn yellow and the branches are dry, which affects the quality of wood and fruit yield, reduces the ornamental value, and causes tree death in severe cases. The branches of the affected trees are easy to break, and pedestrians and vehicles are injured. [0003] Dry borer pests mainly include longhorn beetles, wood beetle moths, orbital elephants, etc. Adults lay their eggs in the bark, and after hatching, the larvae gradually bore into the phloem, cambium, and xylem to cause damage. Because it is less affected by environmental conditions ...

AI Technical Summary

Problems solved by technology

Using natural enemies such as swollen leg wasps, beauveria bassiana, pathogenic nematodes, etc. to control borer pests is the most environmentally friendly method, but the production, transportation, storage, reproduction, and release of natural enemies require certain environmental conditions, the technology is difficult, and the application effect is not good. not ideal

The test found that root irrigation or burying medicine, trunk punching medicine injection or hanging medicine bag, inserting medicine bottle, the control effect on dry borer pests is not ideal.

Injecting liquid medicine into boreholes or defecation holes has a better control effect on borer pests that eat downwards; for borers that eat upwards or have multiple defecation holes, the liquid is very easy to lose , the anti-efficacy is significantly reduced

[0004] In 2010, Qiao Jianguo published "A Paste for Preventing Boring Pests", and obtained the invention patent authorization in 2013, the patent number is ZL 2010 1 0592873.8. The paste has certain fluidity and moderate viscosity, and can solve It solves the problem that the liquid medicine is easy to lose, and has a good control effect on dry-boring pests of one worm, such as longhorn beetle, star beetle, rust-colored beetle, and mulberry beetle. And the species with more defecation holes, such as the small horned wood beetle, the control effect is not ideal
