Description

A kind of Pesticidal combination
Technical field
What a kind of Pesticidal combination of the present invention related to is a kind of Pesticidal combination containing reactive compound spiral shell mite dibasic acid esters and gamma cyhalothrin and uses thereof.
Background technology
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.In addition, the insect also having other kinds of contemporaneous affect plant growth and last output, as aphid, cotton bollworm.
Spiral shell mite dibasic acid esters molecular formula: C20H22Cl2O5, relative molecular mass: 413.29, chemical name is: 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro [4, the 5]-last of the ten Heavenly stems-3-alkene-4-base butyl carbonate.Its molecular structural formula is:
(formula (I)
Mechanism of action as acaricidal spiral shell mite dibasic acid esters mainly suppresses the Fatty synthesis in pest mite body, and without cross resistance between existing miticide, is applicable to the pest mite class for control, existing miticide being produced to resistance.This medicament kills mite and composes wide, strong adaptability, all has fine preventive effect to two spotted spider mite, yellow spider, Xiu Pi lice, yellow tea mite, Tetranychus cinnabarinus and Tetranychus urticae etc., and the mite evil that can be used for the solanaceous crops such as the fruit tree such as citrus, grape and eggplant, capsicum, tomato is administered; Ovicidal effect is excellent especially, if simultaneously to children mite also have good action of contace poison, and lasting period length can control citrus red mite (crm) harm reach 40-50 days.
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:
(formula II)
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.
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 only be used for rushing mite part-time, can not specialized acaricide be used for; And be used alone the existence of spiral shell mite dibasic acid esters in addition to one-tenth mite weak effect, the defect that quick-acting is poor.So, be used alone above-mentioned two kinds of miticides and all do not reach desirable object on miticidal effect.
The typical object occurred in field of pest control needs dose rate and the reduction of reduction control active component or avoids hostile environment or toxicological effects, still allows effective control of insect simultaneously.Also need to combine and knock down control that is active and that extend, i.e. the pest control agent of snap action and long-acting.
