Abstract
The invention discloses a kind of composition pesticide killing plant root-knot nematode, the active ingredient of described composition pesticide is made up of Avermectin, fosthiazate and garlic oil, the weight percentage of described Avermectin, fosthiazate and garlic oil is respectively Avermectin 0.2 ~ 5%, fosthiazate 1 ~ 20% and garlic oil 1 ~ 20%, and all the other are auxiliary agent and filler.A kind of composition pesticide preventing and treating plant root-knot nematode provided by the invention, mixed with garlic oil by Avermectin, fosthiazate, not only synergy is remarkable, improve nematicidal toxicity, delay the pesticide resistance of root-knot nematode, also because garlic oil has fumigation action, the penetrability in soil is high, is easy to play drug effect.Field information proves, the effect of composition pesticide control plant root-knot nematode provided by the invention is high, and have no adverse effect to plant growth, economic and social benefit is remarkable.
Description
Technical field
The present invention relates to pesticide field, particularly relate to a kind of composition pesticide killing plant root-knot nematode.
Background technology
Meloidogyne incognita (
meloidogyneincognita) be one of main nematode China parasitic plant, this nematode belongs to Nematoda, Tylenchida, pad sword suborder, different skin Superfamily, Heteroderidae, root knot subfamily on taxonomy.Its larva is linear, female male imago abnormity, and kiss pin is short and thin, middle oesophageal bulb is flourishing, and rear oesophageal bulb prosperity also has branch, and the front end veutro, the root-knot nematode bodily form that cover intestines are small, be invisible to the naked eye, live in soil or in plant young root, main by soil, seedling, the approach propagation such as to pour water.Its host is mainly tomato, celery, asparagus lettuce, Kidney bean, eggplant, balsam pear various vegetables, also can endanger the multiple kinds of crops such as tobacco, ginger, Chinese yam, peanut.Along with the development of China's agricultural production and rural economy; vegetable at protected field sowing area and cropping index improve constantly; and due to varieties of plant single; arable area is limited; cause crop rotation and rotation of crops difficulty, root knot nematode disease harm is on the rise, and the harm the lighter caused every year can the underproduction 10% ~ 20%; severe one more than 60% even has no harvest, and has had a strong impact on the seed output and quality of vegetables.In addition, peanut and tobacco also because of root-knot nematode harm, bring larger adverse effect to production.
Summary of the invention
The object of the invention is to propose a kind of composition pesticide preventing and treating plant root-knot nematode, to improve the control efficiency to plant root-knot nematode, delay the resistance of root-knot nematode to single medicament, reduce cost accounting.
Based on above-mentioned purpose, the active ingredient of composition pesticide provided by the invention is made up of Avermectin, fosthiazate and garlic oil, the weight percentage of described Avermectin, fosthiazate and garlic oil is respectively Avermectin 0.2 ~ 5%, fosthiazate 1 ~ 20% and garlic oil 1 ~ 20%, and all the other are auxiliary agent and filler.
Optionally, the weight ratio of described Avermectin, fosthiazate and garlic oil is 1:2.5 ~ 20:2.5 ~ 20.
Preferably, the weight ratio of described Avermectin, fosthiazate and garlic oil is 1:2.5 ~ 10:2.5 ~ 10.
Preferably, the weight ratio of described Avermectin, fosthiazate and garlic oil is 1:5:5.
Alternatively, the processing formulation of described composition pesticide is granule or water dispersible granules.
The present invention also provides a kind of purposes of composition pesticide, and described composition pesticide is for preventing and treating plant root-knot nematode.
As can be seen from above, composition pesticide provided by the invention, mixed with garlic oil by Avermectin, fosthiazate, not only increase nematicidal toxicity, because fosthiazate belongs to interior absorption medicament, be conducive to plant absorption, improve the defence capability of root to nematode; Garlic oil not only has certain nematicidal toxicity, and also can improve Avermectin and fosthiazate to the penetrability of nematode and stifling nematocidal effect, thus synergy is more remarkable, can significantly improve economic and social benefit.Meanwhile, because the mechanism of action of three is different, after mixed, the resistance of root-knot nematode to single medicament can be delayed.
