background technology
Chemical control is an important means of agriculturally prevention and corntrol insect.But current, due to kind, the living nature of insect etc., the reasons such as the weak effect that living environment etc. cause, repellence are flourishing can not effectively be prevented and kill off sometimes.Particularly for the pest of Lepidoptera, coleoptera, diptera, Homoptera, Semiptera, Hymenoptera, thrips, arachnids and Nematoda etc., utilize conventional dose to carry out prevention and control and just become increasingly difficult.Therefore, in order to can effectively prevent and kill off can not prevent and kill off or prevent and kill off difficulty pest and seek a kind of new means and method.
Mite class is commonly called as two spotted spider mite, belongs to arachnoide pest, and be one of the important pests of the various crop such as fruit tree, cotton, Solanaceae, vegetables and ornamental flower of causing harm, common harmful mite belongs to Acariformes and Acarina more.Mite class mainly causes harm the leaf of plant, stem and flower etc., and thorn inhales the cauline leaf of plant, and there is the yellowish-brown point of a large amount of needle point size chlorosis in initial stage leaf front, and anaphase blade starts chlorosis from the bottom up and crispaturas, even comes off.Sometimes occur from blade in the middle part of plant, blade turns yellow gradually, come off.Harmful mite occurs many from generation to generation, and fertility is strong, and under suitable temperature and humidity conditions, energy mite population within a short period of time can be doubled and redoubled rapidly, causes very large harm to crops.Evil mite easily develops immunity to drugs to acaricide agent, if do not prevented and not treated in time when serious generation, the blade of the crop that is injured can chlorosis turn white, and withers and falls in advance.Under the torrid zone and greenhouse experiment, the whole year all can occur.The height of temperature determines the number of the growth cycle of each worm state of mite class, reproduction speed and egg laying amount.The weather conditions of extreme arid torrid climate often cause its large generation.
Because mite class generating capacity is large, the breeding cycle is short, hidden, and resistance rises fast, is difficult to control, so use chemical pesticide preparation to remain the main method of mite evil in control agricultural production.
Gamma cyhalothrin (Lambda-cyhalothrin), chemical name: 3-(2-chloro-3,3,3 ,-trifluoropropene base)-2,2-dimethyl cyclopropane carboxylic acid's alpha-cyano-3-phenoxybenzyl ester, its molecular structural formula is:
Gamma cyhalothrin is pyrethroid Insecticidal and acaricidal agent; To tag and stomach poison function; Mechanism of action is the conduction by suppressing insect neural axon position, insect is had to the effect of walking quickly and keeping away, knock down and killing, and insecticidal spectrum is wide, and activity is higher, and drug effect is rapid, resistance of rainwater washing against after spraying; To various pests and other insects such as the Lepidopteras such as wheat, corn, fruit tree, cotton, brassicaceous vegetable, coleoptera and Semipteras, and tetranychid, rust mite, goitre mite, tarsonemid etc. have good result, can doublely control when worm, mite are concurrent.Pink bollworm and cotton bollworm, cabbage caterpillar, turnip aphid, tea geometrid, tea caterpillar, pink tea rust mite, leaf goitre mite, oranges and tangerines leaf moth, tangerine aphid and oranges and tangerines tetranychid, rust mite, peach fruit borer and oriental fruit moth etc. can be prevented and treated, also can be used to prevent and treat multiple earth's surface and public health insect.As prevented and treated pink bollworm, cotton bollworm, second and third in generation ovum contain phase, spray with 2.5% missible oil, 1000 ~ 2000 times of liquid, doublely control two spotted spider mite, bridging worm, cotton leaf bug; Control cabbage caterpillar, vegetable aphid are respectively with 6 ~ 10mg/L, the spraying of 6.25 ~ 12.5mg/L concentration; Control phyllocnistis citrella stainton is sprayed with 4.2 ~ 6.2mg/L concentration.Have certain preventive effect to the insect of sucking mouth parts and evil mite, the mechanism of action and sumicidin, flucythrinate are identical, have good inhibitory action unlike it to acarid.
Cyflumetofen (English common name: Cyflumetofen), chemical name is: the acid of (RS)-2-(4-t-butyl-phenyl) 2-cyano group-3-oxo-3-(the fluoro-o-methyl-benzene of α, α, α-three) propionic acid-2-methoxyethyl.Its molecular structural formula is:
Cyflumetofen is the novel acyl acetonitrile class miticide developed by Japanese great Zhong chemical company, and with existing insecticide without cross resistance, in soil and water, rapid metabolization, decomposition, environmentally friendly.Within 2007, getting permission to register in Japan first and sell, for preventing and treating all kinds of harmful mite on the crops such as fruit tree, vegetables, tea tree and flowers, all having very high activity to the harmful mite of each vegetative stage, if more remarkable to the activity of mite; To diseases such as the insects such as diamond-back moth, prodenia litura, striped rice borer, rice fulgorid, black peach aphid and rice blast, powdery mildew, downy mildew, also there is certain preventive and therapeutic effect simultaneously; To each Plants all without poisoning, all fool proof to non-target organisms such as mammal and aquatile, beneficial organism, natural enemies.
At present, gamma cyhalothrin is used alone mostly, although it can suppress mite class quantity to rise when mite class initial stage of origination uses, quick-acting is better; But when mite class occurs in a large number, just lose control of its quantity, therefore lasting effect is not good, easily produces resistance, can not be used for specialized acaricide; And be used alone cyflumetofen control evil mite time dosage larger, on market, cyflumetofen unit price is too high, therefore cost is higher, and reuses this single miticide and make insect easily produce resistance, and cyflumetofen quick-acting is poor, cannot realize controlling preferably at the beginning of insect pest outburst.So, be used alone above-mentioned two kinds of miticides and all do not reach desirable object on miticidal effect.

biological test example
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is collaborative desinsection and acaricidal action.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (see S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) calculate as follows: if
X is the kill ratio when using the reactive compound A that consumption is m ppm for m g/ha or concentration, is expressed as the percentage accounting for untreated control,
Y is the kill ratio when using the reactive compound B that consumption is nppm for n g/ha or concentration, is expressed as the percentage accounting for untreated control,
E is when using consumption for kill ratio during m and n g/ha or the concentration reactive compound A and B that is m and n ppm, being expressed as the percentage accounting for untreated control,
So
If the desinsection lethality rate of reality exceedes calculated value, then the lethal effect of composition be super add and, namely there is synergy.In this case, the kill ratio actually observed must be over the value of the expection kill ratio value (E) using above-mentioned formulae discovery.
