Description

A kind of emamectin benzoate-chlorfenapyr injection agent that prevents pine nematode

Technical field

The present invention relates to a kind of injection that prevents pine nematode.

Background technology

The pine nematode that is caused by pine wood nematode is the great eqpidemic disease of pine forest.This disease at first makes the pine forest of this state withered in a large number in that Japan is popular, causes huge ecocatastrophe.China began in the Nanjing morbidity in nineteen eighty-three, and national southern forest zone takes place on a large scale now, causes great harm.For the containment pine nematode is popular, various countries' plant pathology and entomologist, all it is right to make supporting movement to cut off enemy trying every possible means, devise a stratagem for forest protection worker and government, but really weary so far specific aim prevention and treatment method.

The regularty of epidemic of pine nematode is annual spring and summer season, carrying pathogenic nematode is the vector insect (Monochamus alternatus) (hereinafter to be referred as band epidemic disease longicorn adult) of pine wood nematode, on healthy pine branch, supplement the nutrients, on branch, cause wound, or be with the epidemic disease longicorn to lay eggs and on branch and tree, cause wound, pathogenic nematode causes the pine tree morbidity withered just along the wound infection pine tree.So killing the cause of disease pine wood nematode of invading the tree body when band epidemic disease longicorn adult supplements the nutrients with medicine is elimination or alleviates the popular harm important method of pine nematode.But pine tree tree height is big, make the cause of disease pine wood nematode in the tree body touch medicine, must make medicine be distributed to each position of tree body equably.Because medicine generally can not conduct in the tree body well, so must select proper auxiliary agent to help medicine in the pine tree body, to conduct.

Though, in the Chinese patent literature storehouse, first dimension salt also there is report, as patent No. application number is that 200410066225.3 Chinese patent ＂ has and tags, the arthropodan composition ＂ of the kill harmful of stomach toxicity and ovicidal action, it is characterized in that: it contains 4 '-Biao-methylamino-4 '-compound and two kinds of active components of pyrrole propyl ether (chemical name 4-Phenoxyphenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether) of deoxidation abamectin benzoate, both weight ratios are between 1: 20 to 1: 400, preferably be not more than 1/100, more preferably no more than 1/40, and be not less than 1/30.Whether it relatively produces effect to insects such as moth, lice, stinkbugs, produce effect for killing of pine wood nematode, does not study and reports.Reason is, pine wood nematode is a kind of worm, but not arthropods, whether first dimension salt can be applied to the pine nematode prevention, and everybody is no bottom in the heart, dosage form is not suitable for killing of pine wood nematode yet, pine wood nematode is in branch, adopts spray, and medicine can not touch pine wood nematode, poor effect does not have substantive killing effect; Component is also unreasonable, does not have good solvent to cooperate with surfactant, makes it be difficult in conduction in the pine tree body, so, on the prevention pine nematode, use little; It is in 200510011428.7 the Chinese patent that similar problem also is present in number of patent application, they relatively be fit to oneself targetedly insect kill, be not suitable in the prevention of pine nematode and treatment, using.

Other looks into the patent No. is 200310117492.4 Chinese patent " a kind of pesticides controlling meloidogyne incognita of pine wood nematode ", reported Avermectin, copper sulphate, oozed Zhan Ling, water has been formed medicament, it adopts spray pattern, kill pine wood nematodes in the withered pine, and, mainly be to be used as main ingredient by copper sulphate, Avermectin is as time medicine, mainly kill longicorn, rely on and to ooze Zhan Ling and be penetrated in the branch and go, in fact, this exhibition of oozing is very limited, basically do not reach in the pine of deep layer and go, so, cause it to apply.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of emamectin benzoate-chlorfenapyr injection agent that prevents pine nematode at the above-mentioned state of the art, and its compatibility is formed rationally, and it is effective to kill pine wood nematode, easy to use.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of emamectin benzoate-chlorfenapyr injection agent that prevents pine nematode is characterized in that component includes:

First dimension salt 0.5%-2%

Tween 80 or polysorbate60 10%-15%

Diethylene glycol butyl ether 15-20%

Organic solvent 65%-72%

Be contained in the injection container, above-mentioned percentage is mass percent.

Preferably, described organic solvent is methyl alcohol, ethanol, propyl alcohol, isopropyl alcohol, n-butanol, the tert-butyl alcohol or sec-butyl alcohol.

Improve, described injection container is made up of two parts again, and main body is a plastic bottle body, the plastic bottle body oral area long conical plastics body that has been threaded.Described injection container bottom has the thin-walled position of being convenient to hole.

Preferably, described pin bottle is directly through ф 30-40mm, long 90-110mm, and plastic tube body diameter small end ф 5-7mm holds 8-10mm greatly, long 50-70mm.

Compared with prior art, the invention has the advantages that: compatibility is formed more rationally targetedly, by appropriate surfactant and auxiliary agent, increased conductivity in pine tree, first dimension salt is conducted in the pine tree body to be more prone to, thereby can kill pine wood nematode, the also reasonable more science of pharmaceutical dosage forms, easy to use and practical, added active substance, in conjunction with injection, killing effect is better, and can play preventive effect, test the pine wood nematodes that shows first dimension salt pair worm and kill also very effective.
