Description
Technical field
The present invention relates to a kind of preparation preventing and treating the pesticidal preparations of Bemisia tabaci, belong to preparation technique of pesticide field.
Background technology
Bemisia tabaci (
bemisia tabaci(Gennadius)) the little Aleyrodes of Homoptera Aleyrodidae is belonged to, be found so far from 1889 on Greece tobacco, be distributed in all land, the whole world except the Antarctic Continent, host plant reaches 600 kinds, become a kind of important pests on vegetables in world wide, economic crops and landscape flower, harm increases the weight of day by day.Bemisia tabaci is one of primary pest on tobacco, it not only stings smoking leaf sap, secretion honeydew, bring out sooty mould, cause tobacco leaf nutriment direct losses, more importantly propagate various plants virus, have a strong impact on the seed output and quality of tobacco leaf, the hazard ratio thorn that Bemisia tabaci initiation virus disease causes is inhaled the harm caused and is wanted serious many.After breaking out greatly soon, the virus disease that it is propagated will with big generation for Bemisia tabaci.On the crop of multiple countries and regions, cause crushing harm by the geminivirus infection of transmission via whitefly, and have the trend increased the weight of year by year.
The conventional dose of preventing and treating now Bemisia tabaci mainly includes machine Phosphorus (as chlopyrifos, orthene etc.), carbamates (as Methomyl, carbosulfan etc.), chlorination nicotinoyl class (Imidacloprid, Acetamiprid, Nitenpyram etc.) and insect growth regulator, IGR (Buprofezin, pyriproxyfen) etc.Due to the biological property of insect itself, the blindness of frequent use chemical insecticide and medication, Bemisia tabaci worldwide creates resistant biotypes to the number of chemical agricultural chemicals comprising nicotinic insecticide, is therefore necessary to seek the insect killing substance that novel insect not easily produces resistance.
Fluorine pyridine worm amine nitrile (Sulfoxaflor) is sulfimide insecticide, and sulfimide insecticides acts on the nervous system of insect, namely acts on binding site unique in choline receptor and plays insecticidal function.Can through leaf, stem, root absorption and enter plant corpus.Be applicable to control cotton fleahopper, aphid, aleyrodid, plant hopper and scale insect etc.Have efficient, fast and the longevity of residure long, effectively can prevent and treat the suction juice class pest to nicotinoids, chrysanthemum ester class, organophosphate and carbamate pesticide generation resistance.Low to arthropods toxicity, be the preferred agents of integrated pest control.
Cycloxaprid is a kind of novel anabasine insecticide, and be the antagonist of nAChR, its activity is significantly better than Imidacloprid.All efficient to Brown Planthopper, white-backed planthopper, small brown rice planthopper, also there is good preventive effect to cabbage aphid and Cucumber blight, have to rice leaf roller anti-effect of holding concurrently preferably, Imidacloprid is significantly higher than to cotton field Bemisia tabaci activity.Be a kind of environment amenable Green Chemistry insecticide, have super-active and unique mechanism of action, extremely low cross resistance makes it produce in the insect of serious resistance traditional neonicotinoid insecticide in control and demonstrates wide application prospect.
But above fluorine pyridine worm amine nitrile preparation and the unitary agent of cycloxaprid encounter the problem of series in actual use.As fluorine pyridine worm amine nitrile preparation, in field uses, to there is production cost higher, owing to easily there is photodissociation, hydrolysis etc. in fluorine pyridine worm amine nitrile in addition in natural environment, make the drug effect of fluorine pyridine worm amine nitrile, lasting effect receives impact, certain impact is received on the control efficiency of insect.Cycloxaprid, as a kind of chemical pesticide, has good control efficiency to insect at present, but in order to improve the control efficiency of medicament to insect, peasant constantly improves the using dosage of medicament, and insect easily produces resistance to medicament in addition.
