Abstract
The invention relates to a combined fipronil and chlorpyrifos pesticide which adopts fipronil and chlorpyrifos as effective components, prevents brown palnthopper and belongs to the manufacture technology of frame chemical. Fipronil and chlorpyrifos are dissolved by acetone according to the weight percent of 1-3:4.75 and are emulsified and prepared into the combined fipronil and chlorpyrifos pesticide. The invention has the advantages of little chemical consumption, good prevention effect, and the like.
Description
Technical field
The composition pesticide that this invention relates to is to be active ingredient with fluorine worm nitrile and chlopyrifos, control paddy rice brown planthopper.Belong to the pesticide chemical manufacturing technology
Background technology
Fluorine worm nitrile: be a kind of phenyl pyrazoles
Insecticide, insecticidal spectrum is wide, and insect based on stomach poison function, is had concurrently and tags and certain systemic function, its mechanism of action is to hinder the control of insect γ-An Jidingsuan
ChlorideMetabolism, therefore to aphid, leafhopper, plant hopper,
LepidopteraLarva, fly class and
ColeopteraEtc. important pests very high insecticidal activity is arranged, crop is not had poisoning.
Chlopyrifos: chlopyrifos is the organic phosphates insecticidal/acaricidal agent.Its insecticidal spectrum is wide, have tag, stomach toxicity and fumigation action.Residual life on blade, is not long, but the residual life in soil is then longer.Therefore, better to the control efficiency of underground insect.Under recommended dose, most crops there is not poisoning, but to the tobacco sensitivity.Controlling object cabbage caterpillar, diamond-back moth, greenhouse whitefly, pea color dive evil mite, soil insects such as fly, lima bean pod borer, two spotted spider mite.
In the agricultural production real process, the pest control problem of easy generation is the generation of pest resistance.The paddy rice brown planthopper has much relations in the big generation in some zones with the single medicament of long-term use in recent years.Go up the insect that produces resistance for control agricultural, wherein one of most economical effective method is that the active ingredient of different kind is carried out composite.According to the actual tests effect judge certain composite be synergy, add and, or antagonism.Compound synergic is well filled a prescription, owing to obviously improved control efficiency, reduced the agricultural chemicals usage amount, thereby delayed the generation of pest resistance to insecticide greatly, and be the important means of integrated control insect.At present, the research of the composite application of fluorine worm nitrile and chlopyrifos seems very important.
Summary of the invention
Be control paddy rice brown planthopper, the present invention has carried out composite with active ingredients such as fluorine worm nitrile, chlopyrifos, develop a kind of combined fipronil, chlorpyrifos pesticide.
To achieve these goals, be 1～3: 4.75 usefulness acetone solution and emulsifications by weight percentage with fluorine worm nitrile, chlopyrifos among the present invention.
The present invention has advantages such as dosage is few, control efficiency is good.
Embodiment
Concrete grammar: test medicine is purchased from the market, adds the preparation that emulsifier is made into needs with acetone solution.Pick up from the abiogenous brown planthopper adult in field, raise 2-3 after generation indoor laying eggs, with 3 age nymph test, the employing infusion process is measured.Carry out preliminary experiment earlier, the rice seedling of no worm, ovum is cleaned, dried, it is standby to cut off some rice roots.The soup that configures is poured in long 27cm * wide 7.5cm * high 5cm stainless steel trough, then rice seedling is put into soup and soaked 30 seconds kinds, taking-up is dried, pack in the Boiling tube of 3 * 30cm, pipe is put into low amounts of water in the end, every test tube insert indoor feeding 3 age 20 of nymphs, put into 27 ± 2 ℃ of culturing room, checked the survival borer population in 48 hours, with the blank solution-treated contrast for preparing.Every concentration repeats 4 times, and the calculation correction lethality is obtained the concentration of lethality 10% and 90%.According to the preliminary experiment result, fluorine worm nitrile, chlopyrifos and compounded combination thereof are diluted to 5 series concentration respectively to paddy rice brown planthopper lethality in 10% and 90% concentration range, the same preliminary experiment of test determination method, calculate lethality and corrected mortality, calculate LC50 and 95% confidence limit with the DPSv7.05 of statistical software.Calculate co-toxicity coefficient according to the method for the abundant proposition of Sun Yun, co-toxicity coefficient is greater than 120 the synergistic effect that is, co-toxicity coefficient is a summation action between 80～120, co-toxicity coefficient less than 80 be antagonism, carry out the pharmacy effect evaluation as standard.
The different proportioning 48h of fluorine worm nitrile chlopyrifos are to the indoor virulence determination of activity result of brown plant-hopper

Draw from above laboratory test results, fluorine worm nitrile and chlopyrifos are higher to the insecticidal activity of paddy rice brown planthopper by the composite back of 1: 47.5,1.5: 47.5,2: 47.5,2.5: 47.5,3: 47.5 part by weight of active ingredient, show as obvious synergistic effect
Application example one: paddy rice brown planthopper
Press fluorine worm cyanogen 2.5%, chlopyrifos 47.5%, calcium dodecyl benzene sulfonate 3.2%, triphen ethyl phenol APEO 12.5%, alkylphenol polyoxyethylene formaldehyde condensation products 1.6%, dimethyl formamide 25%, dimethylbenzene is supplied, and makes missible oil.This prescription is by 2000 times of dilution sprayings, and 48 hours control efficiency are 98.7% behind the medicine.40.7% poisons upright stone tablet missible oil with poison and 5% fluorine worm nitrile missible oil uses after the same method, and 48 hours preventive effects are respectively 72.5% and 89.8% behind the medicine.
