Abstract
The invention discloses a pesticide composition containing flupyradifurone and fluopyram. Active ingredients are flupyradifurone and fluopyram, and weight ratio of flupyradifurone to fluopyram is 10:1-1:10. It shows through a lot of indoor and outdoor tests that the pesticide composition has a remarkable synergistic effect, has a more obviously excellent effect of controlling crop nematodes than flupyradifurone or fluopyram and has good fast-acting property and long duration. Meanwhile, application amount of the pesticide is minimized, residual quantity of the pesticide on plants is reduced, pollution to the environment is mitigated, and generation of drug resistance of nematodes is delayed.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of composition pesticide that is active ingredient with fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides, is mainly used in the control of Plant nematode.
Background technology
Fluorine pyrrole furanone (flupyradifurone), belongs to novel nicotinamide insecticide, acts on the central nervous system of insect, is the antagonist of insect nAChR.Be mainly used in preventing and kill off sucking pest in vegetables, fruit tree, nut, grape and some field crops as aphid, leafhopper, thrips, aleyrodid, scale insect etc.
Fluorine pyrrole bacterium acid amides (fluopyram) is a kind of pyridine ethyl benzamide series bactericidal agent, suppresses mitochondrial respiratory by hindering the electro transfer of succinate dehydrogenase in respiratory chain.Can be used for preventing and kill off the multiple diseases such as gray mold, powdery mildew, stalk break comprised in 70 various crop of grape, pears and drupe, vegetables and field crop etc.
Plant nematode is the very harmful pathogenic microorganism of a class, it has a very wide distribution, of a great variety, adaptive capacity to environment is strong, can colonize in the root system of plant, stem, leaf, seed, young shoot and fruit, by feeding activity, mechanical damage is caused to host plant, and rob the nutrition of host plant, especially its esophageal gland secretion can cause host plant that a series of pathology occurs, and also jointly can infect host plant with other pathogenic microorganism, cause compound disease, cause production loss.In the world, the agricultural losses that plant nematode is caused every year, up to more than 1,000 hundred million dollars, seriously constrain the development of agricultural economy.At present, the medicament of control Plant nematode mainly contains Avermectin, fosthiazate etc., of less types, due to these medicaments for a long time, in a large number, single continuously use, caused increasing Plant nematode to create pesticide resistance, actual control efficiency is not satisfactory.
By the screening of different pesticide species compounded formula, filter out rational formula, effectively can improve the actual control efficiency to pests such as weeds, insect and germs, reduce dosage, reduce costs, delaying the drug-fast generation of pest, is the important means of the agriculturally disease pest and weed comprehensive regulation.The present inventor is in the process furtheing investigate fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides compounded formula, surprisingly fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides carry out composite, within the scope of certain compound proportion, to Plant nematode, there is significant synergistic function, after further study, the present invention is completed.
Summary of the invention
The object of this invention is to provide a kind of composition pesticide containing fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides, be mainly used in the control of crops nematode.
Technical scheme of the present invention: a kind of composition pesticide containing fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides, active ingredient is fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides, the weight ratio of fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides is 10:1 ~ 1:10, preferably than being 5:1 ~ 1:5, fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides gross weight percentage composition are in the composition 0.5 ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described auxiliary element is solvent, emulsifier, wetting agent, dispersant, stabilizing agent, antifreezing agent, thickener, binding agent, disintegrant, defoamer, bleeding agent, macromolecule cyst material, synergist, preservative and filler etc., it is all composition that is conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Nematicidal composition of the present invention can be prepared into the multiple application forms being applicable to agriculturally using, and reasonable formulation has microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, granule and missible oil.
The production technology of the various application forms of described nematicidal composition all belongs to existing known technology, does not repeat them here.
Compared with prior art, the invention has the advantages that:
1, fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides is composite has significant synergistic function, is used alone the control efficiency significantly improved nematode than single dose.
2, fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides two kinds of active components composite, decrease Pesticide use amount, reduce use cost, alleviate the pollution to environment.
3, fluorine pyrrole furanone and fluorine pyrrole bacterium acid amides two kinds of active components composite, the mechanism of action is different, action site increase, delayed the drug-fast generation of nematode, added the service life of agricultural chemicals.

Carry out statistical analysis with DPS statistical analysis software, calculate the LC of each medicament
50, and co-toxicity coefficient (the CTC value of mixture is calculated according to the abundant method of Sun Yun.)
Actual measurement toxicity index (ATI)=(standard agent LC
50/ reagent agent LC
50) × 100
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80 < co-toxicity coefficient (CTC) < 120 show as summation action.
