Abstract
The invention discloses a pesticide composition with flufiprole and benzoylurea insecticide. The effective components are flufiprole and benzoylurea insecticide, the benzoylurea insecticide is one of chlorbenzuron, hexaflumuron and chlorfluazuron, the weight ratio of the flufiprole to benzoylurea insecticide is (1:20)-(20:1), the weight percentage of the weight summation of the flufiprole and the benzoylurea insecticide in the composition is 2-80%. The pesticide composition disclosed by the invention is used for preventing and controlling vegetable plutella xylostella. The preventing and controlling effect of the pesticide composition is obviously improved in comparison with that of a single agent, the use dosage of the pesticide is lowered, the influence on the environment caused by the pesticide is reduced, and the drug use cost is lowered.
Description
Technical field
The present invention relates to a kind of composition pesticide, is take Tintinnid nitrile and process for preparation of benzoylurea compounds as active ingredient, is used for control vegetables diamond-back moth.
Background technology
The resistance problem of pest is a global problem, is agricultural science and technology worker outline problem always.Along with the continuity year in year out of Chemical Control of Harmful Insects, increase and the non-science of agricultural chemicals usage amount are used agricultural chemicals, pest resistance is day by day serious, and the pest species that produces resistance is on the increase.Simultaneously, high-intensity use agricultural chemicals causes that Practice for Pesticide Residue in Agricultural Products exceeds standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, the pesticide of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage more short and sweet, the present invention describes with following specific embodiment, but the present invention only limits to absolutely not these embodiment.The following stated is only the present invention embodiment preferably, only is used for describing the present invention, can not be interpreted as the restriction to scope of the present invention.Should be pointed out that all any modifications of making within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Content described in embodiment all is weight percentage.
Embodiment one: Tintinnid nitrile and the young urea that goes out are mixed to the indoor joint toxicity measuring of diamond-back moth.
Test medicine adopts the 96% former medicine of Tintinnid nitrile, 95% benzoylphenyl urea original medicine.
The diamondback moth larvae that the field gathers is put into off-the-shelf Chinese cabbage seedling, after larvae pupation, pupa is collected in the culture dish that is lined with moisturizing filter paper, putting into the cage of laying eggs sprouts wings by it, then the Chinese cabbage seedling of whole dish being put into the cage of laying eggs allows diamondback moth larvae lay eggs, every dish Chinese cabbage seedling falls the ovum amount when reaching 500 left and right, takes out Chinese cabbage seedling dish, is placed on [temperature: 24-26 ℃ of climatic cabinate; Relative moisture 70%-80%; Illumination: 14 (L): 10 (D)] in allow ovum hatching, raise to 3 instar larvaes.
Adopt the malicious blade method of folder to measure: to beat with the card punch of diameter 1cm and get leaf butterfly, put into culture dish, moisturizing.With the capillary dropper from low concentration, every leaf butterfly drop 1ul liquid, after solvent evaporates and another sheet scribble that the leaf butterfly of gelatinized corn starch is involutory makes the malicious leaf butterfly of folder, make in the complete hole that is put in 12 hole tissue culturing plates.Every processing 4 times repeats, and often repeats to be no less than 12 malicious leaf butterflies of folder, and the processing of establishing the corresponding organic solvent that does not contain medicament in contrast.Connect 1 examination worm in each hole of tissue culturing plate, be placed in normal condition and cultivate.After meeting worm 2-4h, after trying worm and having taken food the pastille leaf butterfly, add the cleaning feed to continue to raise to investigation in cultivating plate hole, eliminate the examination worm that has not eaten a complete leaf butterfly.Each dosage is processed 80 of examination borer populations.After processing, 48h investigation examination worm death condition, record total borer population and dead borer population.
According to survey data, calculate the corrected mortality that each is processed.And according to co-toxicity coefficient (the CTC value of grandson in abundant method calculating mixture.If) contrast lethality＜5%, do not proofread and correct; The contrast lethality is proofreaied and correct between 5%-20%; Contrast lethality＞20%, test need be reformed.Be independent variable x according to the logarithm value of drug concentration (mg/L), take the probit value of corrected mortality as dependent variable y, set up respectively the virulence regression equation formula, adopt DPS software to calculate the LC of single dose and each proportioning mixture
50And mixture co-toxicity coefficient.
Table 1, Tintinnid nitrile and the young urea that goes out are mixed to the toxicity test of diamond-back moth table as a result.
As can be seen from Table 1, Tintinnid nitrile and the young urea that goes out are mixed to diamond-back moth CTC value as 137.60,142.83,176.42,141.39,165.76 take the ratio of 20:1,10:1,1:1,1:10,1:20 respectively, illustrates that the Tintinnid nitrile makes up with the young urea that goes out synergistic effect is arranged.
