Abstract
The invention relates to an insecticidal combination containing benclothiaz and ethiprole. Active components in the insecticidal combination are benclothiaz and ethiprole, and the remaining is auxiliary ingredients for preparing pesticide formulations, wherein the weight part ratio of the active component benclothiaz to ethiprole is (1-30):(40-1). The pesticide formulations capable of being formed by the insecticidal combination are wettable powder, a suspending agent, soluble liquid, emulsion in water and water dispersible granules. The active components benclothiaz and ethiprole account for 1-40% of the total weight parts of the pesticide formulations. The two effective active components of the insecticidal combination have obvious synergistic effects, the insecticidal spectrum is expanded, the pesticide amount is reduced, the preventing effect is improved, residue is less, and the insecticidal combination is long in duration and favorable for delaying pesticide resistance of pests and environmental protection.
Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing benclothiaz and second worm nitrile.
Background technology
Benclothiaz is considered to nematocide usually, thinks the highest to nematode activity, and since compound structure is announced, seldom see the activity research to other field or other insects, the more rare application in agriculture chemical compounding field, its chemical structural formula is as follows:
。
Ethiprole insecticidal wide spectrum, to insect based on stomach poison function, have concurrently and tag and certain systemic action, its insecticidal mechanism is the chloride metabolism hindering insect γ-aminobutyric acid to control, therefore very high insecticidal activity is had, to crop without poisoning to important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleopteras.This medicament can impose on soil, also can foliar spray.Imposing on soil can chrysomelid, the wireworm of control of maize root and cutworm effectively.During foliage spray, all have high-level preventive effect to diamond-back moth, imported cabbageworm, rice thrips etc., and the lasting period is long.
By the impact of Phenylpyrazole insecticides Long-Time Service, the pesticide resistance of current second worm nitrile in many insects is more and more serious, and the lasting period is shorter, medicament lasting period one mistake, and insect again can amount reproduction, continues damage to crops.Therefore in order to better pest control, peasant have to frequently dispenser, and cause dosage significantly to increase, add cost, add residual, increase and destroy the pollution of environment, preventive effect is unsatisfactory.And the insecticide that Long-Time Service is single, insect is easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field is more single.And research and develop the agricultural chemical compound that seems, then the R&D cycle is long, and screening compounds arrangement works is very numerous and diverse, and non-general research and development institution can bear.But the different mechanism of action and without the insecticide rational mixture by a certain percentage of cross resistance, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.
Summary of the invention
In order to solve produced problem in above agricultural production, make full use of synergistic effect that two kinds of active component mixtures produce, improve preventive effect, reduce agricultural cost and delay the generation of pest resistance to insecticide, present applicant proposes a kind of Pesticidal combination containing benclothiaz and second worm nitrile, in this Pesticidal combination, active component is benclothiaz and second worm nitrile, all the other are the auxiliary element of the preparation formulations of pesticide, and wherein the ratio of weight and number of active component benclothiaz and second worm nitrile is 1 ~ 30: 40 ~ 1.
