Abstract
The said insecticide is prepared by recompounding pyrethrin, organophosphorus and carbamate insecticides and high-infiltration potentiate. It is developed for solving the problem of insecticide resistance of bollworm and other cotton pest. With the killing mechanism of contact, inhalation and sterility, the said insecticide is used in killing bollworm and other crop pest with effect superior to cyhalothrin.
Description
This patent relates to a kind of by insecticides such as chrysanthemum ester class, organic phosphates, carbamates and specificity insect growth regulator, IGRs, the insecticide---the prescription and the manufacture method of tetrachlorvinphos that are mixed with solvent, emulsifier, high osmosis synergist etc.
This patent is primarily aimed at the insect of cotton-plant pest-insects such as cotton bollworm and other crops, this insecticides is produced because of accepting single insecticide for a long time serious drug-fast problem develops.
The cotton bollworm cotton of causing harm causes a large amount of underproduction of cotton.The insecticide of control cotton bollworm is existing multiple both at home and abroad at present, but or because of insecticidal mechanism single, or because of certain insecticides drug effect low, or because of long-term heavy dose of single variety insecticide that uses, so that insects such as cotton bollworm produce serious pesticide resistance, especially two, the pesticide resistance of three generations cotton bollworm more very, cause the insecticide effect of certain class single variety to reduce, even lose insecticidal action.According to the peasant in recent years the investigation result of use of insecticide type recognize that because the peasant often selects the insecticide of certain class single variety for use, and increases amount of application for a long time year by year, and conversion insecticide type often not, so that insect has produced pesticide resistance.Based on this reason, the underproduction year by year of Cotton in China output, cotton grower's economic loss is serious, and country is to the purchase volume of cotton also wretched insufficiency.
This patent is in order to solve problems such as above-mentioned crop pests develops immunity to drugs, use the integrated control principle, adopt insecticide compatibilities such as contact killing type, internal-suction type, specificity insect growth regulator, IGR, and be equipped with efficient infiltration synergist development cost insecticide---tetrachlorvinphos.
This patent product tetrachlorvinphos, effect because of contained high-efficient penetrant, make medicine strengthen action of contace poison because of systemic action infiltration insect skin, because of infiltrating the plant cauline leaf, soup increases the stomach toxicity insecticidal effect simultaneously, can avoid cotton sandfly worm to pierce not reaching soup in the cotton boll and can not be poisoned to death, owing to adopted the specificity insect growth regulator, IGR can destroy the synthetic of insect chitin, can cause insect to become moth and irreproducible offspring by pupa.
In view of the comprehensive insecticidal mechanism of this patent product tetrachlorvinphos, can improve disposable killing rate to insect, the speed of knocking down is fast, and the death time is short, and the insect that survives escapes to fall the reserve insecticidal action of specificity insect growth regulator, IGR yet, causes the insect division of history into periods.
The effective ingredient of the used various independent insecticides of this patent is far below the using dosage of single insecticide, so cause desinsection very little to the probability that each insecticides all develops immunity to drugs, simultaneously break off offspring's insecticidal mechanism because of it, the gene of blocking-up pest resistance to insecticide go down to posterity, therefore, the possibility of appearance " omnipotent pesticide resistance insect " is minimum.
The high-efficient penetrant that this patent is used not only has the insecticidal synergistic effect, itself is again the volume increase agent of cotton and other crops.
This patent formula for a product has been determined two kinds of prescriptions through repeatedly screening, and promptly No. 2, No. 1, tetrachlorvinphos and tetrachlorvinphos.
Tetrachlorvinphos No. 1 (high poison) is is mainly prevented and treated the insect on cotton and other the non-edible crops, as cotton bollworm, forestry pest etc.Composition and the proportioning thereof that No. 1, tetrachlorvinphos are as follows:
Composition title quality %
Fenpropathrin 1-5
Parathion-methyl 15-30
Methomyl 4-8
The special 3-10 of farming dream
Emulsifier 3-5
Infiltration synergist 0.3-0.5
The solvent surplus
Tetrachlorvinphos No. 2 (low toxicity) is is mainly prevented and treated the insect of vegetables, grain, fruit tree kind crop.Composition and the proportioning thereof that No. 2, tetrachlorvinphos are as follows:
Composition title quality %
Efficient cypermethrin 1-3
Malathion 10-20
Methomyl 4-8
The special 3-10 of farming dream
Emulsifier 3-5
Infiltration synergist 0.3-0.5
The solvent surplus
No. 1, tetrachlorvinphos and No. 2 used solvents of tetrachlorvinphos are dimethylbenzene, dimethylbenzene-diesel fuel mixtures or diesel oil; Emulsifier is an oil-in-water emulsifiers; Efficient infiltration synergist is the sodium salt mixt of nitrophenols and derivative thereof.
The preparation that No. 2, No. 1, tetrachlorvinphos and tetrachlorvinphos
With raw materials used all good standby by preparation quantity and ratio requirement weighing.Earlier solvent is added in the mixer, in each composition that adds successively under the stirring except that the infiltration synergist.Add various materials and continued again to stir 30 minutes, stop to stir the discharging packing.
Tetrachlorvinphos emulsion dilutes with 1000-2000 times of water, and adding infiltration synergist sprays.
Embodiment
1, test method and processing
3 repetitions have been adopted in this test, each repeats 14 square metres, 8 processing promptly: No. 1 1000 times (water), 1500 times (water) of tetrachlorvinphos, 2000 times (water), No. 2 1000 times (water), 1500 times (water) of tetrachlorvinphos, 2000 times (water), 1000 times of cyhalothrins (water), the clear water contrast.With the three generations cotton bollworm is controlling object, and 20 investigation of strain borer population is decided in each sub-district.
