Abstract

The invention discloses a spirotetramat and fenvalerate containing pesticide composite, which is characterized in that in the pesticide composite, the pbw (parts-by-weight) ratio of spirotetramat to fenvalerate is (1:15)-(15:1). The pesticide composite disclosed by the invention has an obvious synergistic effect, thereby reducing the dosage of pesticides, reducing the cost for pesticide application, saving manpower and material resources, and reducing the environmental pollutions caused by the pesticides; and the pesticide composite is suitable to be used for preventing and controlling pests with piercing-sucking mouth parts.

Description

A kind of composition pesticide that contains spiral shell worm ethyl ester and sumicidin
Technical field
The present invention relates to a kind of composition pesticide, specifically a kind of composition pesticide that contains spiral shell worm ethyl ester and sumicidin.
Background technology
Because the long-term single use of desinsection list agent causes the enhancing of pest resistance, control efficiency is affected, and how to guarantee that the continuity of existing agricultural chemicals is used, and reduces the pesticide producing use cost, is that the potential value of existing agricultural chemicals is a convenient way.Constantly can solve the resistance problem of insect through reasonably composite, but also can improve preventive effect agricultural chemicals.
Spiral shell worm ethyl ester, English spirotetramat by name is the tetronic acid compounds, the insecticidal/acaricidal agent spiral shell mite ester (spirodiclofen) of Bayer company and Spiromesifen (spiromesifen) belong to similar compound.Spiral shell worm ethyl ester has unique function Characteristics, is unique so far two-way interior insecticide of inhaling conductive performance that has.This compound can upwards move down in the whole plants body, arrives at blade face and bark, thereby control reaches the corticole insect of fruit as on romaine lettuce and the Chinese cabbage internal lobe.The interior absorption of this uniqueness can be protected newborn stem, leaf and root, prevents that ovum of insect and larva from causing harm.Its another characteristics are that the lasting period is long, and the effective control that reached for 8 weeks can be provided.Can effectively prevent and treat various suckings pest, like aphid, thrips, wood louse, mealybug, aleyrodid and scale insect etc.Applicable chief crop comprises cotton, soybean, oranges and tangerines, tropical fruit tree, nut, grape, lupulus, potato and vegetables etc.Research shows that it has good selectivity to important beneficial insect such as ladybug, syrphus fly and parasitic wasp.
Sumicidin, English by name fenvalerate, insecticidal spectrum is wide, to the natural enemy non-selectivity, to tag and stomach poison function is main, does not inhale and fumigation action in not having.Respond well to lepidopterous larvae.Insects such as Homoptera, orthoptera, Semiptera also there is effect preferably, but invalid to mite.Be applicable to crops such as cotton, fruit tree, vegetables, soybean, wheat.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.Through the formulation of pesticide screening, filter out rational prescription, can effectively improve actual control efficiency, reduce dosage, reduce cost, delay the generation of pest resistance to insecticide, prolong the service life of medicament, be the important means of the insect comprehensive regulation.The control sucking pest that is mixed of spiral shell worm ethyl ester and sumicidin does not still have report at present and uses.
Summary of the invention
It is long to the purpose of this invention is to provide a kind of good disinsection effect and lasting period, helps the composition pesticide that contains spiral shell worm ethyl ester and sumicidin of the insect comprehensive regulation.
For addressing the above problem, the technical scheme that the present invention adopted is: a kind of composition pesticide that contains spiral shell worm ethyl ester and sumicidin, the ratio of weight and number of spiral shell worm ethyl ester and sumicidin are 1:15~15:1.
