Description

A kind of composition for preventing and treating tea lesser leafhopper
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, being specially a kind of composition for preventing and treating tea lesser leafhopper.
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's esters
Chemical classes: pyrethroid
Physicochemical property: outward appearance is white or light yellow crystalline powder, without visible exogenous impurity.1.219g/m during proportion 25 DEG C 3; Fusing point 78-81 DEG C; Vapour pressure (20 DEG C) 2.3 × (10 negative 7) Pa; Under normal temperature, in water, solvability is extremely low, dissolves in ketone, alcohols and aromatic hydrocarbon solvent.
Action character: theta-cypermethrin belongs to third generation pyrethroid insecticides, be mainly used in the control of the agriculture and forestry injurious insects such as field crop, economic crops, vegetables, fruit tree and the domestic hygiene insect such as 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 produce very strong pesticide resistance to such medicament, preventive effect is not equal to before.
carbaryl
Chemical name: 1 naphthyl N methyl carbamate, has another name called sevin.
Type: insecticide
Physicochemical property: colourless to light brown crystals, fusing point 142 DEG C.In water, solvability (20 DEG C) 120mg/L, is soluble in polar organic solvent dimethyl formamide.25 DEG C of solvability: acetone 200 ~ 300g/L, cyclohexanone 200-250g/L, isopropyl alcohol lOOg/L, dimethylbenzene l00g/L.Stable in neutrality and weak acid environment, stable under light and heat condition.Carbaryl is first mass-produced kind in carbamate insecticide.Nineteen fifty-three is very synthesized by the J.A. cloth made of orchid thunder of U.S. combinating carbide company, Development and Production in 1956.
Carbaryl has tags and stomach poison function, and the neural cholinesterase of insect can be suppressed to make it lethal.But along with large-scale medication, after its application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of composition for preventing and treating tea lesser leafhopper; said composition active ingredient is beta-cypermethrin and carbaryl; wherein the weight ratio of beta-cypermethrin and carbaryl is; beta-cypermethrin: carbaryl=1:1-30:1; thus decrease the consumption of agricultural chemicals; also alleviate the impact for environment, 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:
For preventing and treating a composition for tea lesser leafhopper, active ingredient is beta-cypermethrin and carbaryl, and wherein the weight ratio of beta-cypermethrin and carbaryl is, beta-cypermethrin: carbaryl=1:1-30:1.
