Abstract
The invention relates a pesticide composite which consists of ingredient A and ingredient B, wherein, the ingredient A is Tebufenpyrad, the ingredient B is selected from one of diafenthiuron and fenisobromolate. The formulation screening test proves that Tebufenpyrad, diafenthiuron, and Tebufenpyrad, fenisobromolate are compounded together according to a certain proportion, so that remarkable synergy acts on citrus red mite. The pesticide composite can be prepared into missible oil, aqueous emulsion, microemulsion, suspending agent, water dispersible granule and wettable powder. The composite overcomes and defers the drug fastness of pests, expands controlling spectrum, kills acarids quickly, reduces pesticide cost and alleviates toxicity. The pesticide composite is especially applicable to controlling resistant red and white spiders, and the effect is obviously better than that of using siple dosage.
Description
Technical field
The present invention relates to a kind of acaricide composition and uses thereof, especially a kind of synergic acaricide composition and application thereof that contains tebufenpyrad and butyl ether urea or fenisobromolate.
Technical background
Tebufenpyrad belongs to the amide-type miticide, and its effect is to suppress the electronics transmission.The evil mite based on action of contace poison, is had permeability to plant tissue, but absorption in not having.All effective each breeding time to the mite class, can be used for fruit tree, tea tree, cotton, vegetables control tetranychid, rust mite, tarsonemid, palpus mite, aphid, aleyrodid also there are certain effect.Lasting period can reach more than 40 days.
The butyl ether urea, be a kind of Thiourea Insecticidal and acaricidal agent, can be used for preventing and treating insects such as mite class nearly all on the various crops such as cotton, fruit tree, vegetables, ornamental plants, soybean, aleyrodid, diamond-back moth, cabbage caterpillar, aphid, leafhopper, leaf miner, scale insect, evil mite etc.Inhale and fumigation action in having, under ultraviolet light, change material into, should use at fine day with insecticidal activity.Can use with most of insecticidal bactericides.Facts have proved that this composition not only control efficiency is outstanding, and environmentally friendly.
Fenisobromolate, chemical name be 4,4 '-dibromo diphenylglycollic acid isopropyl ester, be the miticide of a kind of low toxicity, efficient, wide spectrum, tagging property is strong, and the lasting period is long, and to becoming, as if mite and ovum action of contace poison is preferably arranged all, variations in temperature is little to the influence of drug effect.Be widely used on fruit tree, vegetables, tealeaves, cotton and the field-crop, be used to prevent and treat evil mites such as various tetranychids, goitre mite, palpus mite, line mite.Because its particular mechanism of fenisobromolate product, its usage amount progressively enlarge.
The synergistic complex of agricultural chemicals is the expanding prevention spectrum, reduces the effective measures of application cost and raising preventive effect, still finds no the acaricide composition and the application on control fruit tree, cotton red spider thereof of closing tebufenpyrad and butyl ether urea or fenisobromolate up to now.
Summary of the invention
The objective of the invention is to propose a kind of composition that contains tebufenpyrad, said composition has obvious synergistic effect.
A kind of synergic acaricide composition that contains tebufenpyrad and butyl ether urea or fenisobromolate is characterized in that it is made up of effective ingredient tebufenpyrad and butyl ether urea or fenisobromolate, and its parts by weight are respectively 1～80 part and 1～60 part.
Described active ingredient is present in the composition with the synergy composition.
The optimum weight umber of effective ingredient tebufenpyrad is 5～50 parts; The optimum weight umber of active ingredient butyl ether urea is 15～70 parts; The optimum weight umber of active ingredient fenisobromolate is 0.1～30 part.
The Synergistic mite killing composition that contains tebufenpyrad and butyl ether urea or fenisobromolate of the present invention is based on effective ingredient tebufenpyrad and butyl ether urea or fenisobromolate, is equipped with insecticides adjuvant, excipients is mixed with missible oil, aqueous emulsion, microemulsion, suspending agent, water dispersible granules, wetting powder.
The present invention contains the acaricide composition of tebufenpyrad and butyl ether urea or fenisobromolate can be anti-tetranychid, must mite etc. control in the popularization of resistance two spotted spider mite and used.
For achieving the above object, the present invention makes full use of both mutual supplement with each other's advantages by the network analysis to tebufenpyrad and butyl ether urea or fenisobromolate acaricidal properties.Tebufenpyrad and butyl ether urea or fenisobromolate is composite according to certain ratio, obtain a kind of new and effective multi-functional miticide composition.The multiple harmful mite that this miticide antagonism tetranychid, palpus mite etc. are easy to generate resistance has good preventive effect; And inhibition reduces drug cost to the drug-fast generation of unitary agent (tebufenpyrad or butyl ether urea or fenisobromolate).
Beneficial effect of the present invention:
Acaricide composition of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and said composition antagonism evil mite if tree tetranychid, palpus mite etc. have tangible synergy, have significantly improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat young mite simultaneously, if mite, become each attitude evil mite such as mite, reduce control recruitment cost; (3) alternative high-toxic pesticide; (4) possess quick-acting and long-acting two big characteristics; (5) compare with tebufenpyrad or butyl ether urea or the agent of fenisobromolate list, produce and use cost reduces greatly; (6) enhancing of evil mite resistances such as inhibition tetranychid, palpus mite; (7) reduction is to the toxicity of warm blooded animal.
