Description
Technical field
This is the bright pesticide field that belongs to, and relates to the preparation and the application technology scheme of Firponil compounded pesticide.
Technical background
Fluorine worm nitrile (Fipronil) is a kind of Phenylpyrazole insecticides, and its insecticidal spectrum broad based on stomach poison function, has concurrently and tags and systemic action, and quick-acting is good, belongs to the moderate toxicity agricultural chemicals.Be mainly used in the control of insect of various crop such as paddy rice, corn, cotton, banana, vegetables, potato, peanut, beet, tobacco, soybean, Semiptera, Lepidoptera, coleoptera, thrips insect are had high preventive effect.In addition, there is not cross resistance between fluorine worm nitrile and the most of insecticides tested, and the insecticidal activity height, the insect that organic phosphor, carbamate, pyrethroid insectide is produced resistance can effectively be controlled.
Fluorine bell urea, diflubenzuron, desinsection swell, go out young urea, Teflubenzuron belongs to benzoyl urea insecticide; mainly be stomach toxicity and action of contace poison; by suppressing the synthetic of insect chitin, make larva when peeling, can not form new epidermis and cause worm death, the food speed that can also suppress insect that has.So it is be characterized in that the low toxicity lasting period is long, good to Lepidoptera, Diptera pest preventive effect.
In addition, diamond-back moth more popular now and refractory is too strong to chrysanthemum ester class and organophosphorus insecticide resistance, and preventive effect is very poor, and biological species agricultural chemicals effect is come too slowly, and the peasant can not accept.Fluorine bell urea is the reasonable medicament of a kind of control Lepidoptera Noctuidae, fluorine worm nitrile is that diamond-back moth is also had preventive effect, but the price of fluorine worm nitrile is too high, and in the diamond-back moth hotspot resistance is arranged, so both compositely improve preventive effect, have saved cost, reduce crop resistance.
This Recompounded pesticide is to vegetables diamond-back moth, cabbage caterpillar, cotton cotton bollworm, wheat mythimna separata, rice leaf roller, and reaching noctuidae pests such as gypsymoth, dysychira abietis, beet armyworm, prodenia litura, the real noctuid of paddy all has good effect.Utilize tagging and stomach poison function of fluorine worm nitrile, be poisoned to death after making diamond-back moth touch medicament and get food, utilize the interior absorption of fluorine worm nitrile and fluorine bell urea etc. to come the control of progress line time simultaneously, mainly be at that a part of insect that is not poisoned to death, other insects in the control field of can holding concurrently simultaneously.
The object of the invention is to overcome the deficiency that last two insecticides use separately, by combination, utilizes its advantage separately, and the technical scheme of the satisfied insecticides of a kind of result of use is provided.
Summary of the invention
The insecticides of described a kind of fluorine-containing worm nitrile, mainly grand or go out young urea or Teflubenzuron are formed by fluorine worm nitrile and fluorine bell urea or diflubenzuron or desinsection, its percentage by weight is: fluorine worm nitrile 0.1-10%, fluorine bell urea or diflubenzuron or desinsection grand or go out young urea or Teflubenzuron 5-75%.
The insecticides of described fluorine-containing worm nitrile, the best 0.5-8% of fluorine worm nitrile content.Other surplus is auxiliary agent or filler, and said auxiliary agent or filler all are that the technical field of pesticide those of ordinary skill is known.
This insecticides is gathered the advantage of each component in one, and overcome simultaneously and the shortcoming when using separately separately, and have that insecticidal spectrum is wide, the lasting period is long, quick-acting is good, cost is low, the excellent characteristics of preventive effect, be a kind of comparatively desirable insecticides.
