Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to a water dispersible granule containing spirotetramat and applications thereof. The effective components of the composition are high-efficient trans-cypermethrin and spirotetramat, wherein the weight ratio of the high-efficient trans-cypermethrin to the spirotetramat is equal to 1:1 to 1:10. The water dispersible granule maximally relieves the problem of drug resistance of pests, thus reduces the using amount of pesticide and the pollution on environment, is accord with the trends of green and environment-friendliness in the future society, and achieves an optimum protective effect on crops.

Description

A kind of water dispersible granules and application that contains spiral shell worm ethyl ester
Technical field
The invention belongs to the composite technical field of agricultural chemical insecticide, be specially a kind of water dispersible granules and application that contains spiral shell worm ethyl ester.
Background technology
Beta-cypermethrin
English name: theta-cypermethrin
Molecular formula: C 22h 19c i2nO 3
Chemical name: (S) a-cyano group-3-phenoxy benzyl (1R, 3S)-3-(2,2-dichloro dialkylene)-2,2-dimethyl cyclopropane carboxylic acid ester and (R)-a-cyano group-3-phenoxy benzyl (1S, 3R)-3-(2,2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester
Chemical classes: pyrethroid
Physicochemical property: outward appearance is white or light yellow crystalline powder, without visible exogenous impurity.1.219g/m during 25 ℃ of proportions 3; Fusing point 78-81 ℃; Vapour pressure (20 ℃) 2.3 * (10 negative 7) Pa; Under normal temperature, in water, solvability is extremely low, dissolves in ketone, alcohols and aromatic hydrocarbon solvent.
Effect feature: theta-cypermethrin is to belong to third generation pyrethroid insecticides, be mainly used in the control of the domestic hygiene insects such as the agriculture and forestry injurious insects such as field crop, economic crops, vegetables, fruit tree and vegetables, mosquito class bedbug and have that virus killing is efficient, wide spectrum, to people and animals' low toxicity, effect rapidly, the feature such as holding effect is long, have and tag and stomach toxicity, ovicidal, insect is had to the effects such as antifeedant activity, but all there is no systemic action.Resistance of rainwater washing against, has special efficacy to the insect that organophosphorous pesticide has reached resistance especially.Due to use for years, in addition with the cross resistance problem of organic phosphates, carbamates, make insect generally to such medicament, produce very strong pesticide resistance, preventive effect is not equal to before.
Spiral shell worm ethyl ester
Molecular formula is: C 21h 27nO 5
Spiral shell worm ethyl ester has unique function Characteristics, is one of modern insecticide having so far two-way interior suction conductive performance.This compound can upwards move down in whole plant corpus, arrives at blade face and bark, thereby prevents and treats as on romaine lettuce and Chinese cabbage internal lobe, and the corticole insect of fruit.The interior absorption of this uniqueness can be protected newborn stem, leaf and root, prevents ovum and the larval growth of insect.Its another feature is that the lasting period is long, and the effective control that reaches 8 weeks can be provided.
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 water dispersible granules and application thereof that contains spiral shell worm ethyl ester; said composition active ingredient is beta-cypermethrin and spiral shell worm ethyl ester; wherein the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is; beta-cypermethrin: spiral shell worm ethyl ester=1:5-1:10; farthest alleviated the problem of current pest resistance to insecticide; thereby reduced the consumption of agricultural chemicals; also alleviated the impact for environment; the trend that meets future society environmental protection, composition of the present invention is received best crop protection effect.
Technical scheme of the present invention is:
A water dispersible granules that contains spiral shell worm ethyl ester, active ingredient is beta-cypermethrin and spiral shell worm ethyl ester, wherein the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is, beta-cypermethrin: spiral shell worm ethyl ester=1:1-1:10.
As preferably, the weight ratio of beta-cypermethrin and spiral shell worm ethyl ester is, beta-cypermethrin: spiral shell worm ethyl ester=1:2-1:4.
The water dispersible granules that contains spiral shell worm ethyl ester of the present invention, it consists of following component by weight percentage:
Beta-cypermethrin 1-50%,
Spiral shell worm ethyl ester 1-50%,
Agriculture breast 400# 4-7%;
Laminated crystal of sodium disilicate 1-5%;
Alkylphenol polyoxyethylene 5-10%;
Sodium carboxymethyl starch 2-20%;
Kaolin surplus.
As preferably, the water dispersible granules that contains spiral shell worm ethyl ester of the present invention, it consists of following component by weight percentage:
Beta-cypermethrin 5-10%,
Spiral shell worm ethyl ester 10-40%,
Agriculture breast 400# 4-7%;
Laminated crystal of sodium disilicate 1-5%;
Alkylphenol polyoxyethylene 5-10%;
Sodium carboxymethyl starch 2-20%;
Kaolin surplus.
Wherein, the total weight percentage of described active ingredient is 30~60%.
The water dispersible granules that contains spiral shell worm ethyl ester of the present invention, for preventing and treating mealybug, two spotted spider mite, mandarin tree scale insect, is particularly useful for preventing and treating mandarin tree scale insect.
Beneficial effect of the present invention is:
Said composition is composite water dispersible granules 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 mandarin tree scale insect, 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 the mandarin tree scale insect in field.
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 mandarin tree scale insect
Process Co-toxicity coefficient
Beta-cypermethrin 1: spiral shell worm ethyl ester 1 213.6
Beta-cypermethrin 1: spiral shell worm ethyl ester 2 298.5
