Abstract
The invention relates to a desinsection composite with synergy, which comprises chlorfenapyr and chlorfluazuron. The invention relates to a pesticide composite formed by the chlorfenapyr and the chlorfluazuron, and the composite is used for controlling agricultural pests, particularly playing a synergistic effect in the application for controlling diamond back moths and asparagus caterpillars in brassicaceous vegetables.
Description
Technical field
The composition pesticide that this invention relates to is to be active ingredient with capillary and fluorine pyridine urea, prevents and treats the insect on the agricultural.Be particularly useful for preventing and treating the brassicaceous vegetable diamond-back moth and the beet moth has the notable synergistic effect.
Technical background
Capillary (chlorfenapyr) has another name called chlorfenapyr, chemical name: 4-bromo-2-(4-chlorphenyl)-1-(ethoxyl methyl)-5-(trifluoromethyl) pyrroles-3-nitrile.Trade name: eliminate, belong to aryl substituted azole class new type disinsection miticide, do not have cross resistance with other insecticides, the mechanism of action uniqueness.Act on of the conversion of the mitochondria (ADP) of insect bodies inner cell to adenosine triphosphate (ATP).Have stomach toxicity, action of contace poison.Various brills are eaten into, sucked, chew insect and the mite class all has outstanding control efficiency.
Fluorine pyridine urea has another name called UC 62644, presses down hooligan, IKI-7899, CCAI12913, is a kind of phenyl formoxyl urea insecticide, insect based on stomach poison function, is had concurrently stronger action of contace poison, poor permeability, no systemic action.It is mainly being to suppress chitinous synthetic, hinders insect and normally casts off a skin, and makes ovum hatching, larval molting, pupa development deformity, and the emergence of adult, and laying eggs etc. is stoped and is brought into play insecticidal action.Very high to the insect activity, but speed of action is slower, can very fast death behind the larva contact medicine, but food ingestion obviously weakens.This medicine has very high activity to some insects such as multiple lepidoptera pest and orthoptera, coleoptera, Hymenoptera, dipteras, is the insecticide of comparison wide spectrum.The insect that insecticides such as organic phosphor, carbamate, pyrethroid are developed immunity to drugs has good control efficiency.Safer to natural enemy, honeybee, fish, but silkworm is had certain toxicity, be to be more satisfactory insecticide in the current integrated pest control, but quick-acting is poor, medicine valency cost is higher.
Diamond-back moth is a kind of common insect, and the main harm brassicaceous vegetable is often caused crushing disaster.Especially in the zone, south, diamond-back moth is annual takes place.In some serious zone, conventional pesticide composition such as pyrethroid, organic phosphates, carbamates etc., control efficiency is very poor separately.Beet armyworm is a polyphagous pest-insect, the harm multiple kinds of crops, and often fulminant takes place, and has a strong impact on crop yield and quality.This insect epidermis is smooth, and higher drug resistance is arranged, and easily develops immunity to drugs.General organic phosphor and chrysanthemum ester insecticide there is very high resistance.
Go up the insect that produces resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But, the development cost height of new active ingredient, the construction cycle is long, and all produces the speed of resistance forever less than insect.Other method such as crop allocation adjustment, different agricultural chemicals are rotated etc., in the process of practical operation, are difficult to really play obvious effects.
The composition of different cultivars carries out composite, is control resistant insect or the very common way of evil mite.Heterogeneity is carried out composite, according to the effect of practical application, judge certain composite be synergy, add and or antagonism.Compound synergic is well filled a prescription, owing to obviously improved actual control efficiency, reduced the usage amount of agricultural chemicals, thereby the generation of the pest resistance to insecticide that delays greatly is the important means of integrated control insect.Still nobody reported in the composite and application of capillary and fluorine pyridine urea at present.
Summary of the invention
Go up diamond-back moth and the beet armyworm that easily produces resistance in order to prevent and treat agricultural, we have carried out mutual composite synergy research with compositions such as capillary, fluorine pyridine ureas.
The diamond-back moth test medicine provides former medicine for producer, is mixed with the preparation that needs by scientific research center of Shaanxi Welch Crop Protection Co., Ltd..Test method is with reference to " the agricultural industry criteria NY/T1154 of the People's Republic of China (PRC).7-2006》。The examination worm is the pickles chrysalis of picking up from the field, after sprouting wings, indoor Chinese cabbage seedling raised for 5 generations, selected the diamond-back moth third-instar larvae of uniformity, inserted cabbage leaf (black leaf Chinese cabbage, the outermost layer blade) culture dish that diameter is 9 centimetres, every ware connects 30, and every processing connects three wares, sprays under 50PSI pressure with the PottER spray tower, ware of each spray, 3 milliliters of every ware spraying liquids.General each processing is provided with 6-7 concentration gradient.The culture dish of handling is put into 25 ℃, raises in the 12H12H illumination box, checks dead borer population, calculates lethality.Blank spray equivalent clear water.Calculate virulence equation and lethal concentration of 50 LC50 with method of least squares, calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC value) according to the abundant method of Sun Yun, the CTC value greater than 100 for synergistic effect, equal 100 the addition that is, less than 100 be antagonism.Result of the test sees Table 1.
Beet armyworm test medicine producer provides former medicine, is mixed with the preparation that needs by scientific research center of Shaanxi Welch Crop Protection Co., Ltd..Test method is with reference to " the agricultural industry criteria NY/T11544.7-2006 of the People's Republic of China (PRC) ".The examination worm, is raised in indoor artificial feeding after sprouting wings for adopting the beet exigua larvae in field, selects the beet armyworm third-instar larvae of the 5th generation growth uniformity at last.Insert the culture dish of 9 centimetres of the diameters of 10 gram feeds, every ware connects 30, and every processing connects three wares, sprays under 50PSI pressure with the PottER spray tower, sprays a ware at every turn, 3 milliliters of every ware spraying liquids.General each processing is provided with 6-7 concentration gradient.The culture dish of handling is put into 25 ℃, raises in the 12H12H illumination box, checks dead borer population, calculates lethality.Blank spray equivalent clear water.Calculate virulence equation and lethal concentration of 50 LC50 with method of least squares, calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC value) according to the abundant method of Sun Yun, the CTC value greater than 100 for synergistic effect, equal 100 the addition that is, less than 100 be antagonism.Result of the test sees Table 2.
