Description

A kind of Synergistic insecticidal composition and application
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially a kind of Synergistic insecticidal composition and application.
Background technology
sandworm toxin insecticide
According to the chemical constitution of nereistoxin, a series of analog making agricultural insecticide of bio-mimetic syntheses, as cartap, dimehypo, Cupric sulfate, thiocyclam etc., being referred to as sandworm toxin insecticide, is also human development successful first kind animal sources insecticide.
To insect, there is very strong tagging and stomach poison function, also there is certain interior suction and fumigation action, lethality is had to adult, larva, ovum, its site of action is cholinergic synapse, check neural normal delivery and make the nerve of insect not produce reaction to external irritant, when contacting pests or after taking food medicament, polypide is drowse, paralysis very soon, until dead, but polypide poisoning after there is no spasm or overwrought symptom.But its action effect is also very single, after large-scale application, resistance risk is also very high.
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.
