Abstract
The invention discloses a compound insecticidal composition containing flonicamid and isoprocarb, and an application thereof. The synergistic insecticidal composition employs flonicamid and isoprocarb as main effective components, wherein a weight ratio of flonicamid to isoprocarb is 0.1-80 : 0.5-80. The insecticidal composition can produce a relatively high synergistic interaction effect, overcomes or delays pest resistance, has fast insecticidal speed and long efficacy duration, reduces pesticide cost and has a prevention effect obviously higher than that of a single dosage. The insecticidal composition can be used for preventing homoptera pests generated on crops, and is particularly suitable for preventing rice hopper and aphid, with an effect obviously higher than that of the single dosage.
Description
Technical field
The invention belongs to pesticide field, be specifically related to compound pesticide compositions of a kind of fluorine-containing pyridine insect amide and Mobucin and uses thereof.
Background technology
Flonicamid (flonicamid, flunicotamid), chemical name: N-cyanogen methyl. (trifluoromethyl) vitamin PP.
Flonicamid belongs to the lower toxicity insecticide variety.This agent is effective to various suckings pest, and has good osmosis.It can be from root to stem, the infiltration of leaf section, but by leaf section to stem, root osmosis relatively a little less than.
This medicament causes effect by hindering the insect act of sucking.Insect stops to suck after taking in medicament very soon, and is last hungry and dead.
Insect according to electronics sucks behavior (EMIII) parsing, and this agent can make the lancet tissue of the sucking insects such as aphid can't insert plant tissue and cause effect.10% water dispersible granules, every 667m when the insects such as vegetable aphid such as control cucumber
2Use 10% water dispersible granules 30-50g that water is sprayed.When for fruit aphids such as control apples, add water 2500-5000 with 10% water dispersible granules and doubly spray.Use proof through test and land for growing field crops, flonicamid is to various aphids, plant hopper, aleyrodid, leafhopper, fruit bat, wireworm, thrips, ant class, leaf miner, and the first-class sucking pest of springtail has special efficacy, and pests with chewing mouthparts is also had good control efficiency.
Mobucin, chemical name: methylamino formic acid-2-isopropyl phenyl ester, molecular formula: C
11H
15NO
2, structural formula is:
Mobucin is the insecticide that a kind of tagging property has the carbamate of systemic action concurrently.Quick-acting, but the drug effect phase is very short.Be mainly used in preventing and treating rice leafhopper, cotton leafhopper and rice fulgorid etc., and can doublely control thrips, also can prevent and treat other pests with chewing mouthparts.Very little on the Natural Spider Enemies impact, the lasting period is shorter.Harmful to honeybee.Under general concentration, to crop safety, but taro there is poisoning.Should not execute with alkaline agricultural chemicals is mixed, can not use simultaneously with Stam F-34, but use more than 10 days at the interval.
But the insect such as rice fulgorid, aphid is under the condition of present long-term prescription, and resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of insect.The inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant flonicamid and Mobucin.
Summary of the invention
The compound pesticide compositions that the purpose of this invention is to provide a kind of fluorine-containing pyridine insect amide and Mobucin, this Pesticidal combination are the multifunctional insecticide compositions of control homoptera pest.
Another object of the present invention provides this Pesticidal combination and prevents and treats application on the insecticidal materials of resistance homoptera pest in preparation, particularly the application on the insecticidal materials of preparation control plant hopper, aphid.
The objective of the invention is to be achieved through the following technical solutions:
The compound pesticide compositions of a kind of fluorine-containing pyridine insect amide and Mobucin, this Pesticidal combination is take flonicamid and Mobucin as main active ingredient, and wherein, the weight ratio of flonicamid and Mobucin is 0.1~80: 0.5~80.Be preferably 0.5~50: 2~50, more preferably 0.5~10: 4~30, most preferably be 1~10: 1~10.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of flonicamid and Mobucin is 3%~80%.Be preferably 5%~55%, most preferably 10%~40%." % " of the present invention is mass percent.
Compound pesticide compositions of the present invention take flonicamid and Mobucin as main active ingredient and insecticides adjuvant and excipient be mixed with any one formulation that allows on the agricultural chemicals, the preferred emulsion of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion and water dispersion granule.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, emulsifier 600 #, polyoxyethylene polyoxy third rare block compound (such as farming breast 33
#), polyoxyethylene nonylphenol ether etc., excipient comprises solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and usefulness.
Compound pesticide compositions of the present invention has good preventive effect to the multiple homoptera pest that rice fulgorid and snout moth's larva etc. easily produce resistance; And suppress insect to the pesticide resistance generation of unitary agent (flonicamid or Mobucin are arbitrary).
Above-mentioned compound pesticide compositions is prevented and treated application on the resistance homoptera pest insecticidal materials in preparation, and especially the effect on preparation control plant hopper or aphid insecticidal materials is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism homoptera pest such as rice fulgorid, aphid etc. have obvious synergistic function, overcome and have delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the Mobucin single dose with flonicamid, produce and the use cost reduction; (6) suppress homoptera pest to the resistance enhancing of agricultural chemicals, its successful is higher than its single dose to be used.
