Description
Technical field
It is more particularly to a kind of that there is the Pesticidal combination for improving performance the invention belongs to agriculture plant protection field.
Background technology
Active component spiral shell worm ethyl ester (Spirotetramat) is tetronic acid class compound, the Insecticiding-miticiding with Bayer companies
Agent Envidor and Spiromesifen belong to similar compound.Spiral shell worm ethyl ester has unique function Characteristics, is to have two-way interior suction so far
One of modern pesticides of conductive performance.The compound can upwards be moved down in whole plant, arrive at blade face and tree
Skin, so as to prevent and treat such as the insect on romaine lettuce and Chinese cabbage internal lobe, and in skin of fruit tree.This unique absorbability can protect new life
Stem, leaf and root, prevent the ovum and larval growth of insect.Its another feature is that the lasting period is long, it is possible to provide effective up to 8 weeks
Preventing and treating.Spiral shell worm ethyl ester high-efficiency broad spectrum, can effectively prevent and treat various suckings pest, such as aphid, thrips, wood louse, mealybug, aleyrodid
With scale insect etc..Applicable chief crop includes, cotton, soybean, citrus, tropical fruit tree, nut, grape, hops, potato
With vegetables etc..Research shows that it has good selectivity to important beneficial insect such as ladybug, wasp fly and parasitic wasp.
Active component fosthiazate (Fosthiazate) is organic phosphates nematicide, and main effect model is suppression root knot
The synthesis of nematode acetylcholinesterase, available for preventing and treating all kinds of root-knot nematodes, aphid etc..Achieved in China in cucumber, kind
Registration on eggplant, watermelon, can be widely applied to vegetables, banana, fruit tree, the crop such as medicinal material.
Actual agricultural chemicals experience have shown that, repeat and single-minded apply a kind of reactive compound to prevent and treat agricultural pests very
It will cause target organismses fast selective in the case of many, and prevent and treat evil usually using the mixture of different activities compound at present
Worm., can delaying drug resistance generation, reduction amount of application, reduction by the way that the reactive compound with the different mechanisms of action is combined
Cost accounting.
The content of the invention
The purpose of the present invention is to be directed to insecticide resistance and pedo relict problem in actual applications, is filtered out containing two
The insecticide for planting different desinsection principles is compounded, to improve insecticide control effect, and delaying drug resistance is produced, and reduces amount of application,
Reduce cost accounting.
It is a further object of the present invention to provide above-mentioned composition the application in having pest type is prevented and treated in agriculture field.
The purpose of the present invention can be reached by following measures：
The invention provides a kind of Pesticidal combination with synergistic effect, contain effective constituents A and B in said composition,
