Description
Technical field
The invention belongs to rice pest prevention and control field.Specifically related to a kind of pesticide combination containing cartap and hexaconazole
Thing.
Background technology
Paddy rice rice leaf roller, is the insect of harm most serious in growth period duration of rice.Rice leaf roller
[Cnaphalocrocis medinalis (Guenee)] is a kind of migratory pest, and in China, each rice region has generation, and it is dashed forward
Hair property is strong, and hazard area is wide, is one of Insect Pests in Rice, the paddy rice underproduction is caused throughout the year.Rice sheath blight disease is water all the time
Important disease in rice breeding time, causes heavy losses throughout the year.
Cartap belongs to nereistoxin and similar bionic insecticide, and its mechanism of action is：Cartap intrusion insect nerve cell
Joint portion, blocks the acetylcholine secreted by previous nerve cell and conveys to latter nerve cell, so that nerve cell is blocked
Contact, makes insect neural paralysis, it is impossible to nibble food, it is impossible to take action, and stops development, so that dead.Cartap is used as insecticide, has
Efficiently, the advantages of wide spectrum, low toxicity, low-residual, in addition to interior suction, stomach toxicity, a variety of effects such as tag, also with food refusal, ovicidal
Deng effect.Cartap is knocked down soon to insect, and the lasting period is long, desinsection wide spectrum.
Cartap has special efficacy to lepidoptera pest, it is adaptable to the various crop such as paddy rice, corn, vegetables, sugarcane, can prevent harnessing the river
Chilo suppressalis, yellow rice borer, rice leaf roller, pink rice borer, rice plant skipper, paddy stem maggot, ricestem-fly, corn borer, article sugarcane borer and vegetables
150 various pests such as cabbage caterpillar, pickles butterfly, fruit tree oriental fruit months, small heart-eating peach worm, citrus leaf-miner.Cartap is to birds
Low toxicity, it is nontoxic to pest natural enemies such as spiders, it is small to environmental organism lethality.
Hexaconazole is the triazole of new generation researched and developed after triazolone, olefin conversion, Tebuconazole, Difenoconazole, propiconazole
Class efficient germicide.The bioactivity of hexaconazole is similar to triazolone, Triadimenol to sterilization mechanism, wide with antimicrobial spectrum, infiltration
Property and uptake and translocation it is strong, the features such as prevention and treatment effect is good, the mechanism of action is destruction and prevents germ ergosterol biological
Synthesis, causes germ cell membrane to be formed, and finally makes germ dead.Hexaconazole medicament can effectively prevent and treat sac fungus, basidiomycetes
With disease caused by Fungi Imperfecti, especially to disease caused by basidiomycetes and sac fungus for example powdery mildew, rust, scab, brown spot,
Anthracnose, banded sclerotial blight, false smut etc. have preferable preventive and therapeutic action.Applied by recommended dose in suitable for crop, to ring
Border is friendly, to crop safety.
Cartap and hexaconazole are low-toxin farm chemicals, and cartap and hexaconazole respectively have advantage and disadvantage when being each used alone, such as
Cartap quick-acting is good, but lasting effect is poor.
The content of the invention
It is an object of the invention to provide it is a kind of can desinsection again can diseases prevention, lasting effect length, quick-acting fast, low toxicity, environmental protection,
Efficient pesticide-germicide agriculture chemical compounding agent.It is specifically related to the agricultural chemicals of cartap and hexaconazole for active ingredient.
The purpose of the present invention can be reached by following measures：
A kind of composition pesticide containing cartap and hexaconazole, said composition contains active component cartap and hexaconazole,
Wherein the weight ratio of cartap and hexaconazole is 60:1~1:60.
The proportioning of cartap and hexaconazole in the present composition can in the reasonable scope be entered according to specific using situation
Row adjustment, preferably the weight ratio of both cartap and hexaconazole are 50:1~1:50, more preferably 40:1~1:20, further preferably
30:1~1:1, still more preferably 20:1~5:1.
In the present composition mass content of active ingredient cartap and hexaconazole can for 20~70%, preferably 30~
60%.
The composition of the present invention can be equipped with insecticides adjuvant, with skill in the art using cartap and hexaconazole as active ingredient
Method known to art personnel, is made acceptable formulation on agricultural chemicals, such as wettable powder, aqueous emulsion, water dispersible granules, suspension
Agent or solvable pulvis etc..
The composition of the present invention be can be applied to prevent and treat diseases and pests of agronomic crop, and rice leaf roller, water are particularly prevented and treated at the same time
The sheath and culm blight of rice is to the application in terms of murrain.
Composition pesticide of the present invention containing cartap and hexaconazole has the advantage that and beneficial effect：1) it is of the invention
Cartap and hexaconazole composite insecticidal bactericide, emphasis using the disease such as the insects such as rice leaf roller and rice sheath blight disease as preventing and treating
Object, expands the preventing and treating spectrum of harmful organism, having accomplished to control a medicine more, it is simultaneous control a variety of pest and disease damages, reduce spraying times, that is, realize
Dispenser, it is simultaneous to control insect pest, the purpose of disease, the dispenser cost of crop PCO can be effectively reduced, peasant household pair is reduced
The selection difficulty of agricultural chemicals；2) it is environmentally friendly, to farmland beneficial organism and Environmental security, improve the biological Pest control efficacy of natural enemy
While, the ecological environment for also protecting farmland good；3) can emphasis realize for paddy rice middle and later periods most disease and pest preventing and treating；4)
The lasting period is extended, usage amount is reduced.
Embodiment
It is with synergistic effect, summation action or antagonism, the application to confirm cartap and hexaconazole mixture
People has carried out Toxicity Determination using both compositions to paddy rice rice leaf roller and rice sheath blight disease, and synergy uses grandson
Yun Peifa calculates co-toxicity coefficient (CTC) to evaluate mixed effect.
Embodiment 1：Cartap is tested the Toxicity Determination of paddy rice rice leaf roller with hexaconazole mixture.
The method of indoor biometricses is：Using capillary micro intravenous drip method, capillary micro intravenous drip device volume is 1.0 μ L.With
Micro intravenous drip device by decoction by head drop in the back side of the instar larvae of rice leaf roller 3, each concentration handles the larva of 30 or so,
Every 5 larvas are put into a diameter of 9cm culture dish, and a small amount of feed is another to use acetone 30 larvas of drop for taking food built in ware
It is used as control.Larva after processing is still placed in receptacle, and the death rate is checked after 48h.Data are handled with SPSS software statistics.
Toxicity regression formula, the lethal concentration of 50, coefficient correlation etc. are obtained, and co-toxicity coefficient is obtained with the abundant methods of Sun Yun.
The co-toxicity of mixture preparation is represented using Sun Yunpei co-toxicity coefficient method：
Actual measurement toxicity index (ATI)=standard agent LC of mixture50/ reagent agent LC50*100
Theoretical toxicity index (TTI)=Σ (medicine effective ingredients of the toxicity index ATI of certain medicine × in mixture of mixture
Percentage).
Co-toxicity coefficient CTC=mixtures actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI) * 100 of mixture
Synergistic effect criterion after two kinds of effective ingredient compoundings：
It is synergistic effect when CTC is more than 120, is antagonism during less than 80, is addition when 80~120.
