Abstract

The invention belongs to the technical field of pesticide compounding, and concretely relates to a chlorfenapyr-containing missible oil and its application. The effective components of the chlorfenapyr-containing missible oil comprise chlorfenapyr and methidathion, wherein a weight ratio of methidathion to chlorfenapyr is 20:1-1:1. The chlorfenapyr-containing missible oil has a good prevention and control effect especially on tea lesser leafhopper under the synergistic effect of the above components.

Description

The missible oil that contains chlorfenapyr and application
Technical field
The invention belongs to the composite technical field of agricultural chemical insecticide, be specially a kind of missible oil that contains chlorfenapyr and application.
Background technology
Methidathion
One of English name is Methidathion, CAS 950-37-8, molecular formula C 6h 11n 2o 4pS 3, molecular weight 302.3313.

Content: 98.00-99.50%
The pyroles Insecticidal and acaricidal agent of structure novel, has good preventive effect to boring moth, thorn suction and chewing type insect and mite class.This medicament has following characteristics: broad spectrum insecticide, miticide; Have stomach toxicity and action of contace poison concurrently; With other insecticides without cross resistance; On crop, there is medium residual activity; In nutrient solution through the selective systemic activity of Root Absorption; It is high that this class has selectivity, and the mechanism of action is unique, and toxicity is low waits good characteristic, but its action effect is also very single, and 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 missible oil that contains chlorfenapyr and application, active ingredient is chlorfenapyr and methidathion, wherein the weight ratio of chlorfenapyr and methidathion is, methidathion: chlorfenapyr=10:1-1:10, especially good to control tea lesser leafhopper, be mainly by the result of the synergistic function between each component.
Technical scheme of the present invention is:
A missible oil that contains chlorfenapyr, active ingredient is chlorfenapyr and methidathion, wherein the weight ratio of chlorfenapyr and methidathion is, methidathion: chlorfenapyr=10:1-1:10.
As preferably, the weight ratio of chlorfenapyr and methidathion is, methidathion: chlorfenapyr=5:1-1:1.
The missible oil that contains chlorfenapyr of the present invention, it consists of following component by weight percentage:
Methidathion 1-50%,
Chlorfenapyr 1-50%,
Agriculture breast 500#15-40%,
Isooctanol 10-25%,
Kerosene 5-25%.
As preferably, the missible oil that contains chlorfenapyr of the present invention, it consists of following component by weight percentage:
Methidathion 10-50%,
Chlorfenapyr 5-10%,
Agriculture breast 500#15-40%,
Isooctanol 10-25%,
Kerosene 5-25%.
Wherein, the total weight percentage of described active ingredient is 30~60%.
As further preferred, the missible oil that contains chlorfenapyr of the present invention, it consists of following component by weight percentage:
Methidathion 50%,
Chlorfenapyr 10%,
Agriculture breast 500#20%
Isooctanol 10%
Kerosene 10%.
The missible oil that contains chlorfenapyr of the present invention, for preventing and treating liriomyza bryoniae, large trypetid, tea lesser leafhopper, is particularly useful for preventing and treating tea lesser leafhopper.
Beneficial effect of the present invention is:
Said composition is compounded cream composition, compare with single product, the feature with binary composition, strengthened significantly effect, delay the generation of pest resistance to insecticide, and expanded effective active control spectrum, and thering is 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 alleviated the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment, met the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control tea lesser leafhopper, is mainly by the result of the synergistic function between each component.
To the compound synergic research of composition of the present invention, test adopts tea lesser leafhopper for test.
Concrete grammar is: according to the abundant method of Sun Yun, calculate the toxicity index of medicament and mixed co-toxicity coefficient (CTC value).
The toxicity test result of the different proportion relations of table 1 to tea lesser leafhopper
Process Co-toxicity coefficient
Methidathion 10: chlorfenapyr 1 135.7
Methidathion 5: chlorfenapyr 1 207.5
Methidathion 1: chlorfenapyr 1 210.3
