The acaricidal composition plays a synergic effect through compounding, is wide in application range, and friendly to environment, has fast-acting property and persistence, can be used for preventing and treating a plurality of pest mites such as spider mites on a plurality of crops, such as fruit trees, vegetables, tea leaves, as well as spider mites and rust mites on oranges and tangerines, and has an excellent effect on eggs of mites, and the lasting period can be up to 30 days.
Description
Technical field
The invention belongs to the technical field of agricultural chemicals, be specifically related to a kind ofly contain Profenofos and second mite azoles carries out composite miticide composition, and the application aspect control crops evil mite.
Background technology
The bromo-2-chlorphenyl of Profenofos (Profenofos) chemical name O-ethyl-O-(4-)-S-propyl dithiocarbamate phosphate, belongs to organophosphorus insecticide.Structural formula is as follows:
Former medicine outward appearance is light yellow liquid, tool is garlicky, 100 ℃/1.80Pa of boiling point, vapour pressure 1.24 * 10^ (4) Pa (25 ℃) density 1.455 (20 ℃), KowlogP=4.44, solvability water 28mg/L (25 ℃), with most immiscible organic solvent, more stable under neutral and micro-sour condition, unstable in alkaline environment, Profenofos belongs to the asymmetric high osmosis type broad-spectrum organophosphorous pesticide of ternary, have and tag and stomach toxicity, stifling, straight osmosis, can directly permeate in blade and polypide, thoroughly kill hide in blade (back side), in paddy field, fruit neutralization pierces stalk.Profenofos is the thiophosphate insecticides that a kind of molecule contains positive rosickyite base, and its insecticidal spectrum is wide, easily biological-degradable, and antagonism insect shows high biologically active.
Second mite azoles (Etoxazole) claims to come again good fortune Lu, chemical name (the RS)-5-tert-butyl group-2-[2-(2,6-difluorophenyl)-4,5-dihydro-1.3-uh azoles-4-yl] ethoxybenzene.Structural formula is as follows:
Former medicine outward appearance is white tasteless crystal powder, molten some 101.5-102.5 ℃, proportion 1.2389kg/m3, vapour pressure (25 ℃) 7.0 * 10-6Pa, solvability (g/L, 20 ℃) water 7.04 * 10-5, acetone 309, ethyl acetate 249, normal heptane 18.7, methyl alcohol 104, dimethylbenzene 252.Belonging to 2,4-diphenyl-oxazole derivatives quasi-compound, is a kind of selectivity miticide.Be mainly the process of casting off a skin that suppresses mite class, thereby mite is had to excellent tagging property from ovum, larva to pupa different phase.Its mode of action comprises inhibition cast off a skin normally process and ovicidal activity, although can not directly kill into mite in addition, female one-tenth mite is had to good sterile effect.
Above-mentioned two kinds of medicaments are used separately due to long-term, easily cause the drug-fast generation of mite, cause drug effect obviously to decline, thereby cause dosage greatly to rise, the sprinkling cycle shortens, and result of use is poor, increased cost, the use of a large amount of agricultural chemicals, makes mite resistance more serious, also environment is affected, the medicament residue of agricultural product also increases, have influence on health and the normal existence of the mankind, animal etc., Profenofos and second mite azoles are carried out to composite use control crops acarid evil, there is not yet report both at home and abroad.
Summary of the invention
The object of the invention is to provide a kind of for the problems referred to above and carry out composite miticide composition and application thereof by Profenofos and second mite azoles, by composite, play synergistic effect, applied widely, tool quick-acting and lasting effect, environmentally friendly, can be used to prevent and treat tetranychid and the multiple harmful mite such as the tetranychid on oranges and tangerines, rust mite in the various crop such as fruit tree, vegetables and tealeaves, and mite ovum is also had to tall and erect effect, and the lasting period reaches 30 days.
In the present invention, second mite azoles, the weight of Profenofos, the weight of active ingredient etc. mentioned, all refer to the weight after folding hundred, i.e. the weight of active principle.
Bactericidal composition containing second mite azoles and Profenofos of the present invention, its active ingredient consists of second mite azoles and Profenofos, and the weight ratio of described Profenofos and second mite azoles is, Profenofos: second mite azoles=100:1～1:100.
As preferably, the weight ratio of described Profenofos and second mite azoles is, second mite azoles: Profenofos=1:2～1:10.
Wherein, in said composition, the weight percentage of active ingredient is 1%～90%.
Said composition formulation comprises wetting powder, suspension emulsion, missible oil, oil suspending agent, adds auxiliary agent and excipient, and the production technology of all knowing according to those skilled in the art can be made into required formulation.
This miticide composition can be used to prevent and treat the multiple harmful mites such as tetranychid in the various crop such as fruit tree, vegetables and tealeaves and the tetranychid on oranges and tangerines, rust mite, and mite ovum is also had to tall and erect effect, and the lasting period reaches 30 days.
Beneficial effect of the present invention is: in miticide development and application process, delaying drug resistance or cross resistance are the key factors that extends the product shelf life-span, rationally use miticide, control access times and dosage, the miticide of different mechanism of action is used alternatingly and just seems particularly important.
embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited thereto, and the formulation preparation method in embodiment is conventional method.
