Description
Technical field
The invention belongs to pesticide field, and in particular to a kind of desinsection using propargite with silicon ethofenprox as principle active component
Composition and its application.
Background technology
Propargite (Propargite), molecular formula：C19H26O4S, chemical name：2- (4- tert-butyl benzene oxies) cyclohexyl third
Alkynes -2- base sulfites.Structural formula is：
Propargite is broad spectrum activity, efficiently, less toxic acaricide, have and tag and stomach poison function, no infiltration and systemic action.It is right
Children mite and good into mite effect, ovicidal effect is poor.Can effectively preventing and treating apple-tree, cotton, cucumber, grape, corn and soybean, kind
Tetranychid class pest on eggplant and vegetables.
Silicon ethofenprox (Silafluofen), structural formula：
Silicon ethofenprox is siliceous pyrethroid insecticides, and effect is close to ethofenprox, available for rice, cotton-plant pest-insects
Prevention.Effect is rapid, and insecticidal spectrum is wide, and ichthyotoxin is very low, is expected to use in paddy field.It is right suitable for prevention rice, vegetables, on cotton
Homoptera Delphacidae special efficacy, while to various pests such as Lepidoptera, Semiptera, Orthoptera, coleoptera, Diptera and Isopteras
There is good effect.It is especially notable to the prevention effect of rice hoppers.
Insecticide variety containing single component often existing defects in pesticide control of insect：Continuous use easily produces anti-
Pharmacological property, insecticidal spectrum are narrow, it is impossible to provide comprehensive protection, peasant's drug cost height etc. for crop.It is various by two kinds or the coming year
The combination of active ingredient can overcome disadvantages mentioned above to a certain extent to a certain extent.Two kinds or two with synergistic effect
The combination mixture of kind above active ingredient, can improve preventive effect, and dosage, cost-effective with reducing active ingredient, slows down pest
Resistance, which occurs simultaneously can expand to prevent, composes, and plays that more worms are simultaneous to be controlled, reduces the use cost of peasant.
The content of the invention
It is an object of the invention to for above-mentioned various problems, in order to overcome and delay the resistance to the action of a drug to existing pesticide, expand
Big insecticidal spectrum, enhancing drug effect, reduce drug cost, so as to provide a kind of prevention various crop Homoptera, Lepidoptera, mite class disease pest
Harmful Pesticidal combination.
It is a still further object of the present invention to provide the purposes of the Pesticidal combination.
The measure of the present invention is realized by following measures.
A kind of Synergistic insecticidal compositions containing propargite Yu silicon ethofenprox, the Synergistic insecticidal compositions are with propargite and silicon ether
Chrysanthemum ester is principle active component, wherein, the weight ratio of propargite and silicon ethofenprox is 1:60~60:1.
The more excellent weight ratio of the Pesticidal combination, wherein propargite and silicon ethofenprox is 1:50~30:1.Further
It is preferred that the weight ratio of propargite and silicon ethofenprox is 1:20~20:1, still further preferably propargite and the weight ratio of silicon ethofenprox
For 1:1~10, the weight ratio of most preferably propargite and silicon ethofenprox is 1:5~10.The weight ratio of propargite and silicon ethofenprox is also
Can be 1：10、1：5、1：10、1：2、1：3、1：1.
The weight ratio of preparation shared by the two kinds of active principle accumulations of the Pesticidal combination, wherein propargite and silicon ethofenprox
For 0.5%~90%, preferably 1~60%.
The Pesticidal combination, using propargite and silicon ethofenprox as principle active component (active ingredient) and auxiliary agent and/
Or excipient is processed into any one formulation allowed on pesticide.The formulation that can be processed into is missible oil, suspending agent, aqueous emulsion, micro-
Emulsion, pulvis, wettable powder, dispersible oil-suspending agent and water dispersible granules etc..The auxiliary agent can use detergent alkylate
Sulfoacid calcium, alkylphenol polyoxyethylene ether, polyoxyethylene polyoxy propylene block compound (such as agriculture breast 33#), Nonyl pheno
Ether etc., excipient include cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water.Above auxiliary agent,
Excipient and other agriculturally known auxiliary materials can be alone or be used in combination.
The Synergistic insecticidal compositions containing propargite and silicon ethofenprox are being prepared for preventing cereal crop, fruit
Tree, flowers, cotton, tea tree, the Homoptera on vegetables, Lepidoptera, mite pest insecticide in apply.
The lepidoptera pest is bollworm, leaf miner, and homoptera pest is plant hopper, and mite pest is red spider, sweet tea
Dish noctuid, tetranychid, Panonychus citri.
The present invention Synergistic insecticidal compositions antagonism mite pest have significant preventive effect, particularly with tetranychid, red spider,
The various pests that Panonychus citri etc. easily produces resistance have good preventive effect；And suppress pest to unitary agent (propargite
Or silicon ethofenprox) the resistance to the action of a drug produce and at the same time can prevent bollworm etc..
The Pesticidal combination of the present invention compared with prior art, produces following beneficial effect：(1) compared with single dose, the group
Prevention of the compound to pest has notable synergistic, and prevention effect significantly improves；(2) one medicines more control, a dispenser can at the same time anti-Zhiduo County
Kind pest, reduces prevention recruitment cost；The desinsection prepared by the Synergistic insecticidal compositions containing propargite and silicon ethofenprox
Medicine is preventing mite class at the same time, and can prevent Homoptera, lepidoptera pest, especially to cotton boll worm, small brown rice planthopper and beet night
Moth has good preventive effect, reaches the effect that a medicine is controlled more.(3) alternative high-toxic pesticide, and field dosage is greatly reduced, have
Effect reduces environmental pollution and pesticide residue；(4) have concurrently quick-acting and long-acting；(5) compared with propargite single dose, production and application cost
Reduce；(6) suppressing pest strengthens the resistance of pesticide.
