Problems solved by technology

[0004] In addition, the patent No. is 200310117492.4 Chinese patent "A kind of insecticidal and nematicide for pine wood nematodes". It is reported that avermectin, copper sulfate, zaozhanling, and water form a medicament, and it adopts a spraying method to kill dead Pine wood nematodes in pine wood, because the preparation form is not suitable for killing pine wood nematodes, pine wood nematodes are in the branches, using sprays, it is impossible for the medicine to come into contact with pine wood nematodes, the effect is very poor, and it cannot effectively kill pine wood nematodes However, it cannot prevent healthy pine trees from pine wood nematodes. Moreover, copper sulfate is mainly used as the main drug, and avermectin is used as the secondary drug to kill Monochamus alternatus. In fact, this kind of penetration is very limited, the composition is unreasonable, there is no good solvent and surfactant to cooperate, so it is difficult to conduct in the pine tree, and basically cannot reach the deep pine wood. , therefore, causing it to be unable to promote the application

Embodiment 1

[0021] Embodiment 1, reference figure 1 .

[0022] A kind of abamectin injection for preventing pine wood nematode disease, its component is:

[0023] Abamectin 3%

[0024] Tween 80 or Tween 6012%

[0025] Diethylene glycol butyl ether 16%

[0026] Organic solvent 69%

[0027] The above-mentioned percentages are percentages by mass, and are contained in injection containers.

[0028] The injection container is composed of two parts, the main body is a plastic bottle body, and the mouth of the plastic bottle body is threaded with a long cone

[0029] Shaped plastic pipe body, there should be no leakage at the threaded connection, and the long tapered plastic pipe body can be precisely combined after being inserted into the tree body without leaving any gaps, so as to avoid air leakage affecting the infusion. The needle bottle has a diameter of φ35mm and a length of 100mm. The diameter of the small end of the plastic tube is φ6mm, the large end is 9mm, the length is 60mm, ...

[0034] A kind of abamectin injection for preventing pine wood nematode disease, its component is:

[0035] Abamectin 2%

[0036] Tween 8012%

[0037] Diethylene glycol butyl ether 18%

[0038] Organic solvent 68%

[0039] The above-mentioned percentages are percentages by mass, and are contained in injection containers.

[0040] Others are the same as in Example 1.

Abstract

The invention relates to an abamectin injection to prevent pine wilt disease, which is characterized in that, the components of the invention are 2% to 4% abamectin, 10% to 15% tween 80 or tween 60, 15% to 20% butyl glycol ether and 68% to 72% organic solvent; the components are arranged in an injection container; the percentage is mass percentage. The abamectin injection has the advantages that, compatibility composition is more reasonable and more pertinent; through proper surface-active material and addition agent, the conduction of abamectin in pines is easier, therefore pine wood nematode can be eliminated; the form of the pharmaceutical preparation is more reasonable and more scientific; the invention has convenient use and practicality; active substance is added; combined with injection, the invention has better killing effect.

Description

technical field [0001] The invention relates to an injection for preventing pine wood nematode disease. Background technique [0002] Pine xylophilus disease caused by pine xylophilus is a major disease of pine forests. The disease first became popular in Japan, causing a large number of pine forests in the country to die, causing a huge ecological disaster. my country began to develop the disease in Nanjing in 1983, and now it occurs on a large scale in the southern forest areas of the country, causing great harm. In order to curb the prevalence of pine wood nematode disease, plant pathologists and entomologists, forest protection workers and governments in various countries are trying to find ways to deal with it, but so far there is no targeted control method. [0003] The epidemic law of pine wood nematode disease is that in spring and summer every year, the vector insect (Pine Beetle) carrying the pathogenic nematode pine wood nematode (hereinafter referred to as the ...
