The compound insecticide disclosed by the invention is simple in production process and safe to use, cannot cause pollution to the environment, is low in toxicity and high in efficiency, also cannot cause harms to beneficial insects in use, can be used for expanding insecticidal spectrums, and can be used for significantly improving the fast-acting performance of medicines by virtue of the compounding of two medicaments, namely the emamectin benzoate and the diafenthiuron.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compounded pesticides containing emamectin benzoate and diafenthiuron.
Background technology
Emamectin benzoate is a kind of new and effective semisynthetic antibiotics insecticide, almost can be used for all crops, prevent and treat the very desirable medicament of the effect of nearly all insect, there is the feature of super-high-efficient, low toxicity, low-residual, the biopesticide such as nuisanceless, by strengthening the neurotic effect as glutamic acid and Y mono-aminobutyric acid (GABA), a large amount of chlorion is made to enter insect nerve cell, upset its nerve conduction, make larva that irreversible paralysis occur, and lethal.To the larva of lepidopterous insects and the activity of other many insect high, the effect having stomach toxicity concurrently and tag, does not injure beneficial insect in the process of pest control, to all plant height safety, be a kind of environment amenable low-toxin farm chemicals, be now used on a lot of cereal crops and economic crops.
Diafenthiuron belongs to Thiourea miticide, kill mite quick-acting good, at utmost drug effect can be played in several hours after the spraying of direct sunlight weather, there is interior suction, tag, stomach toxicity and fumigation action, disturb neural energy metabolism by insect, destroy neural basic function, suppress chitin synthesis, first two spotted spider mite benumbs, later just dead.If all effective to one-tenth mite, young mite mite and ovum, can be used for the mite class, aphid, aleyrodid, leafhopper, various the moth pests etc. of preventing and treating on fruit tree, cotton, vegetables, tea and ornamental plants has high anti-validity.
Although, emamectin benzoate and diafenthiuron have good pest control effect, but emamectin benzoate is easily photodissociation fast in the environment, in addition because peasant excessively uses, cause the increase of pest resistance, emamectin benzoate has become current efficient medicine from the specific drug of control Lepidoptera class pest, and control efficiency declines.There is above-mentioned shortcoming too in diafenthiuron.Although also there is part compound product, unreasonable due to composite consumption, cannot play the effect of synergy.
