Abstract
The invention discloses a pesticide composition. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A adopts afidopyropen; the active ingredient B is selected from one of paichongding, cycloxaprid and cycolxylidin; the weight ratio of the active ingredient A to the active ingredient B is (1:80) to (80:1). The pesticide composition is used for controlling and preventing various injurious insects, such as plant hoppers and thrips, has an excellent synergistic interaction effect, and can improve the controlling and preventing effect, and reduce the usage amount of pesticide and the use cost of farmers.
Description
Technical field
The invention belongs to agricultural insecticide field, relate to particularly Pesticidal combination and application thereof that a class contains afidopyropen.
Background technology
Afidopyropen (test code number ME5343) is a kind of novel pesticide of Japanese Meiji Pharmaceutial Ltd. and the joint research exploitation of Japanese Kitasato Kenkyusho (JP) 9-1, Shirokane 5-chome, Minato-ku, Tokyo 108, Japan.This product is a kind of brand-new structure and has brand-new mechanism of action, can prevent and treat suction type mouthpart insect as aphid, plant hopper, scale insect and leafhopper etc. for vegetables, fruit tree, vine, intertillage crop and ornamental plants etc.
The pyridine of piperazine worm is new and effective, wide spectrum, low toxicity nicotinic insecticide, mode of action uniqueness, and the aixs cylinder that acts on insect nerve conduction is touched acceptor, and block nerves conduction, shows as strong feeding deterrent.There is stronger interior suction conduction, can be absorbed rapidly by crop, rice fulgorid, tea lesser leafhopper etc. are had to good control efficiency.
Cycloxaprid (Cycloxapyrid) is a kind of novel nicotinamide insecticide, is formulated by East China University of Science.This compound has interior suction, stomach toxicity and action of contace poison, can be used for preventing and treating Homoptera, coleopteran pest on crops, without cross resistance, also effective to lepidoptera pest with Imidacloprid, Acetamiprid, epoxy insect quinoline etc.This product using dosage is low, environmentally safe, to beneficial organism without harm or endanger minimum.Aphid to crops such as wheat, cotton, paddy rice, fruit tree, vegetables, aleyrodid, plant hopper, flea beetle, cotton bollworm, diamond-back moth, prodenia litura, armyworm etc. have higher insecticidal activity.
Epoxy insect quinoline (Cycloxylidin) belongs to anabasine insecticide, is formulated by Wuhan Engineering Univ.This compound has interior suction, stomach toxicity and action of contace poison, and structure approaches with Imidacloprid, but active in Imidacloprid, and the sucking pest such as aphid, aleyrodid is had to higher activity.
The technical scheme being used in combination about afidopyropen and the pyridine of piperazine worm or cycloxaprid or epoxy insect quinoline at present has no report.

Two, biological activity determination and test of pesticide effectiveness example
The combination of active principles of different agricultural chemicals is made to agricultural chemicals, is effectively and the efficiently mode of one of the upper resistant insect of current development novel pesticide and control agricultural.The agricultural chemicals of different cultivars shows three kinds of type of action: summation action, synergistic effect and antagonism after mixing conventionally.But be specially which kind of effect, unpredictable, only have by lot of experiments and could determine.
Inventor is by a large amount of screening tests, find that afidopyropen and the pyridine of piperazine worm or cycloxaprid or the combination of epoxy insect quinoline have obvious synergistic function to the sucking pest such as plant hopper, thrips, thus, the embodiment of the present invention also provides the application of above-mentioned Pesticidal combination suckings pest such as control Brown Planthopper, Frankliniella occidentalis.Control efficiency is not only the simple addition of two kinds of medicaments, is specifically illustrated with following biologicall test example.
One) the composite joint toxicity measuring to Brown Planthopper of biologicall test example: afidopyropen and the pyridine of piperazine worm or cycloxaprid or epoxy insect quinoline
For examination object: Brown Planthopper (Nilaparvata lugens (Stdl)), resource environment institute of Agricultural University Of South China Pesticide Science be the sensitive population providing, and use pot rice indoor culture, picking consistent 3 age nymph be used for test.
Test method: with reference to farm-chemical indoor determination test rule insecticidal n Y/T1154.11-2008, adopt rice stem infusion process.
Mode of application is judged co-toxicity coefficient (CTC) method that adopts.The computing formula of co-toxicity coefficient is as follows:
Actual measurement toxicity index (ATI)=(standard medicament LC
50/ reagent agent LC
50) × 100
The percentage composition of B in percentage composition+B medicament ATI × mixture of A in theoretical toxicity index (TTI)=A medicament ATI × mixture
Co-toxicity coefficient (CTC)=[the theoretical toxicity index of mixture actual measurement toxicity index (ATI)/mixture (TTI)] × 100
When CTC≤80, composition performance is for antagonism, and as 80 < CTC < 120, composition performance is for summation action, and when CTC >=120, composition performance is synergistic effect.
Result of the test: afidopyropen and the pyridine of piperazine worm, afidopyropen and cycloxaprid, afidopyropen and epoxy insect quinoline, the composite rear joint toxicity measuring to Brown Planthopper the results are shown in Table 1-3 respectively.
