Problems solved by technology

Pine wood nematode disease has the characteristics of strong pathogenicity, fast host death, and fast transmission. Once it occurs, it will be difficult to control, which will not only cause huge losses to the national economy, but also destroy the natural landscape and ecological environment, and pose a serious threat to pine resources. threaten

Embodiment 1

[0016] An insecticide for preventing and controlling pine wood nematode is a pest control composition prepared from dimethoate and carbofuran as main raw materials for the occurrence and development of pine wood nematode disease; the weight percentage of its raw material components Including: Dimethoate EC 40%, Carbofuran Granules 15%, fillers make up 100%.

[0017] The use method of the insecticide for controlling pine xylophilus is to apply 50 times of the insecticide to the bark of pine trees.

Embodiment 2

[0019] An insecticide for preventing and controlling pine wood nematode is a pest control composition prepared from dimethoate and carbofuran as main raw materials for the occurrence and development of pine wood nematode disease; the weight percentage of its raw material components Including: 50% Dimethoate EC, 10% Carbofuran Granules, 100% filling.

[0020] The method for using the insecticide for preventing and controlling pine xylophilus is to punch and inject 100 times of the insecticide into pine trees.

Embodiment 3

[0022] An insecticide for preventing and controlling pine wood nematode is a pest control composition prepared from dimethoate and carbofuran as main raw materials for the occurrence and development of pine wood nematode disease; the weight percentage of its raw material components Including: 60% Dimethoate EC, 5% Carbofuran Granules, 100% filling.

[0023] The use method of the insecticide for controlling pine xylophilus is to spread 100 times of the insecticide on the soil.

Abstract

The invention belongs to the field of agricultural production and discloses an insecticide for preventing and treating pine wood nematodes and an application method of the insecticide. The insecticide is the insecticide which aims at the pine wood nematodes caused by pine wood nematode diseases and is obtained by mixing main raw materials, namely dimethoate and carbofuran; the insecticide is coated on pine tree barks or a pine tree is punched and the insecticide is injected into the pine tree, or the insecticide is scattered on soil, so that the pine wood nematodes can be effectively prevented and treated; and the insecticide has a simple formula and is convenient to use, and is applicable to the prevention and the treatment of the pine wood nematodes in a pine planting process.

Description

technical field [0001] The invention belongs to the field of agricultural production, and in particular relates to an insecticide for preventing and controlling pine wood nematode and its application method. Background technique [0002] Pine wood nematode disease, also known as pine wilt disease, is a devastating epidemic of pine trees. It is a disease of pine trees caused by the spread of pine wood nematodes in pine trees through vector insects such as monochamus. After being infected by pine wood nematode, the needle leaves are yellowish brown or reddish brown, wilting and drooping, the resin secretion stops, and the long beetle intrusion holes or traces of spawning can be observed in the trunk, and the whole plant of the diseased tree dries up and dies, and finally rots. Pine wood nematode disease has the characteristics of strong pathogenicity, fast host death, and fast transmission. Once it occurs, it will be difficult to control, which will not only cause huge losses ...
