Embodiment 1

[0019] The whole plant of the succulent plant Peach Beauty is taken, washed and dried naturally, and then the juice of the Peach Beauty plant is collected by physical pressing method, and set aside. Another fluorite is crushed and passed through a 100-200 mesh sieve to obtain fluorite powder for later use.

[0020] Completely immerse the fluorite powder in a sufficient amount of peach beauty plant juice (it can be completely immersed at the beginning of immersion, and there is still liquid juice after immersion), and after fully immersing for 4-6 hours, the fluorite is Dry at low temperature (20-30°C) until the water content is lower than 5wt%, and grind to nano powder (50-200nm).

[0021] The modified fluorite nanopowder prepared above was added into ethyl linoleate in an amount of 1 wt% to fully disperse to prevent and control pine wood nematodes.

Embodiment 2

[0023] Take the whole plant of the succulent plant Komatsu japonica, wash it and dry it naturally, and then collect the plant juice of the succulent plant by means of physical pressing, and set it aside. Another fluorite is crushed and passed through a 100-200 mesh sieve to obtain fluorite powder for later use.

[0024] Completely immerse the fluorite powder in a sufficient amount of white flower Komatsu plant juice (it can be completely immersed at the beginning of immersion, and there is still liquid juice after immersion), and after fully immersing for 4-6 hours, the fluorite is Dry at low temperature (20-30°C) until the water content is lower than 5wt%, and grind to nano powder (50-200nm).

[0025] The modified fluorite nanopowder prepared above was added into ethyl linoleate in an amount of 1 wt% to fully disperse to prevent and control pine wood nematodes.

[0026] The scheme in the following application examples of the present invention is to carry out further research...

Abstract

The invention belongs to the technical field of agricultural pest control, and in particular relates to the application of ethyl linoleate in the control of pine wood nematode disease. The scheme of the present invention is based on the prevention and control scheme of pine wood nematode disease with ethyl linoleate in the prior art, and the fluorite nanometer after the juice modification treatment of selected succulent plants is further added to ethyl linoleate. Powder, can be at 0.5‑5μl / m 3 Under the situation of the low-dose ethyl linoleate application rate of pine body, further improve the diapause rate of B. xylophilus, make a large amount of B. xylophilus stop breeding, and form diffusion type B. xylophilus (comprising the third instar larvae of diffusion type (L. III ) and diffuse fourth instar larvae (L IV )) to reduce the transmission of the vector insect Monochamus alternatus during the eclosion period from January to May of the next year, which can effectively control pine wood nematode disease.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest control, and in particular relates to the application of ethyl linoleate in the control of pine wood nematode disease. Background technique [0002] Pine wood nematode disease, known as the "cancer" of pine trees, is the most dangerous forest disease in the world. It is a devastating disease of pinaceae plants. The entire pine forest can be destroyed within 5 years, which is extremely harmful. The destructiveness of pine wood nematode disease lies in: strong pathogenicity, fast host death; fast spread, and often caught off guard; once it occurs, it is difficult to control. It not only causes huge losses to the national economy, but also destroys the natural landscape and ecological environment, and poses a serious threat to my country's rich pine forest resources. At present, the control of pine wood nematode disease mainly depends on removing all diseased trees, but because of the par...
