Abstract
The invention belongs to the technical field of pesticide compounding, and particularly relates to a suspension emulsion of theta-cypermethrin and pyridaben and the application of the suspension emulsion. The active ingredients of the compound include theta-cypermethrin and pyridaben, and the weight ratio of theta-cypermethrin to pyridaben is 5-20 to 1. The suspension emulsion of theta-cypermethrin and pyridaben maximally alleviates the problem of pest resistance to insecticide in the prior art, so as to reduce the pesticide consumption and the influence on the environment, and coincide with the trend for a green future society. The compound provided by the invention achieves the optimal crop protection effects.
Description
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially suspension emulsion and the application of a kind of beta-cypermethrin and pyridaben.

Pyridaben is wide spectrum, contact acaricide, can be used for preventing and treating multiple food vegetalitas evil mite.If to whole vegetative period of mite and ovum, young mite mite with become mite and have good effect, obvious speed is had to kill effect equally to the one-tenth mite of mobile phase.This medicine is not acted upon by temperature changes, and no matter uses in early spring or autumn, all can reach promising result.
But its action effect is also very single, after large-scale application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of suspension emulsion and the application thereof that have beta-cypermethrin and pyridaben; said composition active ingredient is beta-cypermethrin and pyridaben; wherein the weight ratio of beta-cypermethrin and pyridaben is; beta-cypermethrin: pyridaben=5:1-20:1; farthest alleviate the problem of current pest resistance to insecticide; thus decrease the consumption of agricultural chemicals; also the impact for environment is alleviated; meet the trend of future society environmental protection, composition of the present invention receives best crop protection effect.
Technical scheme of the present invention is:
A suspension emulsion for beta-cypermethrin and pyridaben, active ingredient is beta-cypermethrin and pyridaben, and wherein the weight ratio of beta-cypermethrin and pyridaben is, beta-cypermethrin: pyridaben=5:1-20:1.
As preferably, the weight ratio of beta-cypermethrin and pyridaben is, beta-cypermethrin: pyridaben=10:1-15:1.
The suspension emulsion of beta-cypermethrin of the present invention and pyridaben, it consists of following component by weight percentage:
Beta-cypermethrin 10-30%,
Pyridaben 1-5%,
Solvent 5-10%
Wetting agent 1-3%
Emulsifier 4-8%
Antifreezing agent 6-7%
Dispersant 2-5%
Defoamer 0.1-2%

The suspension emulsion of beta-cypermethrin of the present invention and pyridaben, for preventing and treating citrus, apple, pears, hawthorn, cotton, tobacco, the insect of vegetables and ornamental plants and mite class, is particularly useful for control citrus and European red mite.
Beneficial effect of the present invention is:
Said composition is compound suspend emulsion composition, compared with single product, there is the feature of binary composition, significantly enhance effect, delay the generation of pest resistance to insecticide, and expand effective active control spectrum, have speed fast, the lasting period is long, consumption is low, eco-friendly feature, the more important thing is, this compounded combination has effectively resisted the problem that pest resistance produces, farthest alleviate the problem of current pest resistance to insecticide, thus decrease the consumption of agricultural chemicals, also alleviate the impact for environment, meet the trend of future society environmental protection.The control efficiency of composition of the present invention to control citrus and European red mite especially good, mainly by the result of the synergistic function between each component.
Study the compound synergic of composition of the present invention, test adopts European red mite to be used for test.
Concrete grammar is: calculate virulence equation and lethal concentration of 50 LC50 by method of least squares, calculates toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament according to the abundant method of Sun Yun.
Table 1 different ratio relation is to the toxicity test result of European red mite
| Process | LC50（PPM） | Co-toxicity coefficient |
| Beta-cypermethrin 5: pyridaben 1 | 0.883 | 542.6 |
| Beta-cypermethrin 10: pyridaben 1 | 0.715 | 723.9 |
| Beta-cypermethrin 15: pyridaben 1 | 0.66 | 829.5 |
| Beta-cypermethrin 20: pyridaben 1 | 0.739 | 620.0 |
| Beta-cypermethrin | 20.78 | ? |
| Pyridaben | 0.579 | ? |
As can be seen from Table 1, beta-cypermethrin and pyridaben composite, have very high synergistic effect, especially beta-cypermethrin: during pyridaben=10:1-15:1, synergistic effect is more obvious, and especially detailed to the effect of European red mite.
