Problems solved by technology

The reason is that pine wood nematode is a kind of worm, not an arthropod. Whether emamectin benzoate can be used to prevent pine wood nematode disease is uncertain, and the preparation form is not suitable for killing pine wood nematode. The nematodes are in the branches. With spray, the drug cannot touch the pine wood nematode, the effect is very poor, and the substantive killing effect is not achieved; the components are also unreasonable, and there is no good solvent to cooperate with the surfactant. It is difficult to conduct in the pine body, so it is not used in the prevention of pine wood nematode; similar problems also exist in the Chinese patent that the patent application number is 200510011428.7, and they are more suitable for their targeted pests. Suitable for the prevention and treatment of pine wood nematode
[0005] In addition, the patent No. is 200310117492.4 Chinese patent "A kind of insecticidal and nematicide for pine wood nematodes". It is reported that abamectin, copper sulfate, zaozhanling, and water form a medicament, and it adopts a spraying method to kill dead The pine wood nematode in pine wood mainly relies on copper sulfate as the main drug, and abamectin as the secondary drug, mainly to kill the longhorn beetle, relying on the osmosis spirit to penetrate into the branches. In fact, this osmosis is Very limited, basically can't reach the deep pine wood, so it can't be popularized and applied

Embodiment 1

[0022] Embodiment 1, reference figure 1 .

[0023] A kind of emamectin benzoin injection for preventing pine wood nematode disease, its component is:

[0024] Emamectin 1%

[0025] Tween 80 13%

[0026] Diethylene glycol butyl ether 16%

[0027] Methanol 70%

[0028] The above-mentioned percentages are percentages by mass, and are contained in injection containers.

[0029] The injection container is composed of two parts. The main body is a plastic bottle body. The mouth of the plastic bottle body is threaded with a long tapered plastic tube. , leaving no gaps, so as not to affect the infusion due to air leakage. The diameter of the needle bottle is ф35mm, the length is 100mm, the diameter of the small end of the plastic tube is ф6mm, the large end is 9mm, the length is 60mm, and the volume is 60ml. The bottom of the bottle body of the injection container has a thin-walled part that is convenient for drilling.

Embodiment 2

[0036] A kind of emamectin benzoin injection for preventing pine wood nematode disease, its component is:

[0037] Emamectin 0.5%

[0038] Tween 80 12%

[0039] Diethylene glycol butyl ether 16%

[0040] Methanol 71.5%

[0041] The above-mentioned percentages are percentages by mass, and are contained in injection containers.

[0042] Others are the same as in Example 1.

Embodiment 3

[0044] A kind of emamectin benzoin injection for preventing pine wood nematode disease, its component is:

Abstract

The invention relates to an emamectin benzoate injection to prevent pine wilt disease, which is characterized in that, the components of the invention are 0.5% to 2% emamectin benzoate, 10% to 15% tween 80 or tween 60, 15% to 20% butyl glycol ether and 65% to 72% organic solvent; the components are arranged in an injection container; the percentage is mass percentage. The emamectin benzoate injection has the advantages that, compatibility composition is more reasonable and more pertinent; through proper surface-active material and addition agent, the conduction of emamectin benzoate 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 ...
