Description

Insecticidal composition for wood-boring insect containing trupentine as an active ingredient and use according to the present invention.

The present invention relates to a composition for puncture pest control of trees containing turpentin as an active ingredient and its use, and more particularly, it contains turpentin as an active ingredient and further contains beeswax or paraffin, gum rosin and ethyl alcohol. Or it relates to a composition for controlling puncture pests of trees which further contain vegetable oil, and a method of using the composition for the purpose of preventing penetration of puncture pests of trees into the stem or trunk of the trees.

Trees are damaged by various pests, depending on the type of insect pests, leafy pests that infuse leaves, absorptive pests that absorb sap from leaves or branches, and punctures that puncture holes by applying water (branches, stems). In addition, the insects can be divided into worm-forming insects that make insect lumps on leaves and stems, and seeds and coniferous pests that inflict seeds or conifers. Among them, perforated pests are damaged by puncturing the branches and stems of trees. Adds tissue to impede the movement of sap, degrades the value of wood, and creates pupils in water weakness or even tree death or even wood, causing loss of value as a landscape tree or shortening the life of the tree. .

In recent years, damage to wood-based pests has been increasing, but no pesticides have been officially registered for the control of wood-borne pests. Although the spraying method is used, most of these pesticides are mainly sprayed in areas close to human life such as landscape water, park water, and roadside trees, and are highly toxic pesticides, causing concern about environmental pollution and human toxicity due to the spraying.

Due to the excessive use of chemical pesticides, environmental problems such as pollution of soil and water and disturbance of ecosystems due to soil microorganisms and natural enemies are emerging as major social issues.

Chemical pesticides, which have been used for decades, are resistant to pests and can only be controlled by using more pesticides or more lethal pesticides over time. I'm making it serious. Accordingly, research on low-toxic, non-toxic, pollution-free biological pesticides to replace chemical pesticides is being actively conducted.

Biological pesticides include microbial pesticides, biochemical pesticides and pesticides using natural enemies. Microbial pesticides refer to agricultural microbial control agents that use living microorganisms such as fungi, bacteria, viruses, and protozoa. Biochemical pesticides use natural compounds produced in nature or biocommunication materials by non-toxic mechanisms. Substance or herbal remedies.

On the other hand, biochemical pesticides include natural product pesticides composed of natural ingredients such as animals and plants, pheromones, enzymes and minerals, and pesticides produced in plants by genes introduced into plants. Such biopesticides can be used as a substitute for chemical pesticides because they are non-residual and have no impact on humans and the environment.

However, in the case of such environmentally friendly pesticides, the handling of raw materials is generally not easy, and the control value is lower than that of chemical pesticides, which is a commercial obstacle and there is a limitation in generalization. In addition, most biopesticides and natural pesticides are economically and ineffective due to their high price, have a weak control effect or extremely limited effects, and have a problem that the drug efficacy is not rapid but full effect. It has not been well received and has not succeeded as a substitute for chemical pesticides.

Therefore, there is an urgent need for the development of wood-penetrating pest control agents that are harmless to humans and animals and plants, are environmentally friendly, easy to handle, low in production price, easy to supply raw materials, and high in control.

The inventors of the present invention while conducting research for the development of such a puncture pest control agent of the tree, the environment-friendly material turpentine (turpentine) excellent insecticidal effect against the puncture pest of the tree and the puncture pests of the tree or The present invention was completed by finding out that there is an effect that can prevent invasion of water.
