Abstract
The invention belongs to the field of pesticides and particularly relates to a composition for controlling tangerine pest mites. The composition comprises flutenzine and milbemectin as effective constituents. When the flutenzine and the milbemectin as the effective constituents of the composition are mixed mutually, no conflict is generated. The composition disclosed by the invention has a very good synergistic effect within a certain range, has a control effect superior to that of a single dose and more lasting pesticide effect, delays the generation of pesticide resistance, reduces the repeat number, the consumption and the use cost of a pesticide, and is particularly effective for the tangerine pest mites. The composition disclosed by the invention can be further applied to pest mite control of other fruit trees.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of for preventing and treating the composition of pest mite of citrus.
Background technology
For preventing and treating the medicament of phytophagy evil mite, be called miticide, generally can only kill mite and can not desinsection to have acaricidal action kind concurrently more, but their main activity of miticide is desinsection, can not be called miticide, sometimes also claims that they are Insecticidal and acaricidal agent.For endangering a class agricultural chemicals for the arachnids pests such as each Plants, reserve substance, domestic animal.In miticide, some kinds are active high to Mobile Forms mite (becoming mite and young mite, weak mite), to ovum poor activity, even invalid; Some kinds are high to ovum activity, to or dynamic mite weak effect; Two kinds of some kinds can be killed.Common miticide kind has that mite is dead clean, pyridaben, hexythiazox.
Oranges and tangerines, evergreen dungarunga or shrub, high about 2m.Sprig is thinner and more delicate, without hair, and common spinosity.The long ovum shape of leaf lanceolar, long 4～8cm.Brightly yellowish white, single raw or axil that clusters.Fruit oblate spheroid, footpath 5～7cm, orange-yellow or orange red, pericarp is thin easily to be peeled off.Bloom spring, and 10～December, fruit was ripe.Property happiness warm and moist weather, cold resistance is slightly strong compared with shaddock, bitter orange, sweet orange.Citrus Rutaceae Aurantioideae is the torrid zone, subtropical evergreen fruit trees (except trifoliate orange), is used as 3 genus that have of Economical cultivation: Poncirus, Citrus and Fortunella.The oranges and tangerines of China and the cultivation of world other countries are mainly Citrus.
All kinds of harmful mite of oranges and tangerines belongs to arachnids, mainly comprises goitre mite, tetranychid and tarsonemid three sections.The common tetranychid of China has panonychus citri, oranges and tangerines beginning tetranychid, Eotetranychus sexmaculatus and oranges and tangerines Schizotetranychus.All with sucking mouth parts, suck.
The female body of panonychus citri is about 0.4 millimeter, ellipse, and back side protuberance, peony, dorsal body setae white, and is born in verruca.Staple length surpasses line spacing.Male body is about 0.35 millimeter.
Raw 15～18 generations in southern china year, generation overlap, with ovum with become mite to survive the winter at branch and blade back, warm regional winter can normal spawning.
In the evil mite onset stage, the agricultural chemicals such as miticide, kerosene emulstion, lime sulfur, galecron, plictran are used in rationally rotation; Treelet, nursery also can adopt systemics to do deep subsoil dispenser, hold concurrently and can protect natural enemy, control mite evil.
Citrus red mite, blister mite are the topmost two kinds of harmful mites in south China tangerine district, conventional organic phosphor in the past, and the chemical controls such as organic nitrogen, organochlorine, organic sulfur, due to use for years, Hai Man district produces serious pesticide resistance, and preventive effect constantly declines.Two spotted spider mite, blister mite are the important harmful mites of global Citrus, and annual control needs beat 10-20 time agricultural chemicals, particularly at fruiting period in order to reduce really rate of casting skin, improve commodity value, almost control per week once, severe contamination fruit and environment, people and animals' pesticide poisoning also happens occasionally.
The fluorine mite piperazine mechanism of action is unique, not only ovum and one-tenth mite is had to excellent activity, and makes female mite produce unsound ovum, causes destroying the evidence of mite, to natural enemy and Environmental security.Its synthetic method is, with o-chlorobenzaldehyde and 2,6-difluorobenzaldehyde, for initiation material, first o-chlorobenzaldehyde reacts with hydrazine hydrate, then with the condensation of 2,6-difluorobenzaldehyde, then chlorination, closed loop, oxidation obtain object.Its synthetic method is: take cyclopentanone dimethyl as initiation material, with dimethyl carbonate, through alkylation, decarboxylation; Generate with iodo trimethyl sulfoxide (being made by iodomethane and dimethyl sulfoxide (DMSO)) expoxy propane replacing again; Finally react with triazole, process and obtain fluorine mite piperazine.
Milbemectin is mainly used in fruit tree as various harmful mites of control such as oranges and tangerines.Active similar to Avermectin, but toxicity is low, than Avermectin safety.
