Abstract
The present invention relates to homogeneous composite pesticide insecticide--highly efficient 'mieshaling' for overcoming the drug resistance of pests. The insecticide is a composite preparation which is composed of two or more than two kinds of pyrethroid insecticide, synergistic agents, emulsifying agents and organic solvent. The insecticide utilizes synergistic action and the relationship of negative cross resistance among some insecticide for overcoming the biologic drug resistance of the pests for the existing various kinds of insecticide, the characteristics of high efficiency, broad spectra, low toxicity and low residue of pyrethroid are reserved, disinsection effect is enhanced, and killing ranges are expanded. Dosages can be decreased by 1/2 to 1/6, and the use cost is greatly reduced; therefore, the insecticide is more suitable for pests which generate serious resistance, the service life of the existing insecticide is extended, and the resources of the existing insecticide are protected.
Description
The present invention relates to a kind of similar composite pesticide insecticide Pesticidal combination.
As everyone knows, crop pests can produce the biomolecule resistant energy to certain chemical pesticide of long-term single use, thereby causes existing insecticide insecticidal effect extreme difference or inefficacy.Be unfavorable for protecting existing insecticide resource.According to synergistic effect between two kinds of insecticides and negative resistance relation, have two kinds of dissimilar insecticides are made composite dose of use, for example with chrysanthemum ester class ten organic phosphors (or organochlorine class or carbamates), this composite dose be widely used after, effect was better in initial 2 years, but facts have proved that through 5-6 insect has also produced serious resistance.
The objective of the invention is at the shortcoming in the above-mentioned existing complex preparation, and a kind of efficient, wide similar composite insecticidal agent formulation of insecticidal spectrum is provided, it can stop the generation of resistance, even can overcome resistance.
The object of the present invention is achieved like this:
By two kinds of pyrethroid insecticideses, be aided with synergist, emulsifier and organic solvent are formed.
The proportioning of each component is as follows: (percentage by weight):
The summation of two kinds of pyrethroid insecticideses accounts for 16-40%
Synergist 9-40%
Emulsifier 7-10%
Organic solvent 10-68%
Pyrethroid insecticides is cypermethrin and sumicidin, and the proportioning of the two is:
Cypermethrin 4-16%
Sumicidin 12-24%
Synergist can select following any: synergy phosphorus, Butacide, Octachlorodipropyl Ether, synergy spirit.
Organic solvent be following any: benzene,toluene,xylene, ethanol, benzene alcohol mixture.
Reparation technology of the present invention is as follows:
By a certain each component of ratio requirement weighing, at first pyrethroid insecticides is put in the reactor, through fully stirring, add synergist more successively, organic solvent and emulsifier are proceeded to stir the Yin Deben Pesticidal combination.Again can through press filtration packing seal.
The present invention has carried out comprehensive screening to existing chrysanthemum esters product, has selected existing fine synergistic effect, and stronger negative resistance relation is arranged again, the above-mentioned chrysanthemum ester insecticide of can also be complementary different separately desinsection scopes.Finishing on the basis of measuring the co-toxicity coefficient between two kinds of above-mentioned kinds,, compoundly produce success in conjunction with a large amount of field trials.Through insectary 2-4 for cotton bollworm test and continuous 5 years same block of soils on the uses of crops, does not still have discovery generation resistance.
Pesticidal combination of the present invention has kept fully not only that its chrysanthemum ester class is efficient, the characteristic of wide spectrum, low toxicity, but also newly-increased following advantage: 1, be difficult for producing resistance.2, the desinsection scope is wide.3, consumption is few, and use cost is low.Chrysanthemum ester insecticide is used for cotton-plant pest-insects because of the kind difference, and general consumption is 25-60 milliliter/mu, and is serious as resistance, when the mu consumption reaches the 90-120 milliliter, also has little effect.And this Pesticidal combination mu consumption promptly reaches optimum efficiency for 15 milliliters, and the highest consumption is 35 milliliters/mu.4, it has increased ovum, miticidal effect extremely, and double repellent, food refusal and fumigation effect.5, reach the health rank, can kill family, public health insect and storage pests such as mosquito, fly, flea, lice, bedbug, cockroach, casemaking clothes moth, silverfish, ant.
This Pesticidal combination series of products have been listed Hebei province's emphasis new product development in 9 years plan in, and through 200,000 mu of land for growing field crops insecticidal tests, effect is fine, is subjected to praising highly of peasant and expert.
Following table has been listed embodiments of the invention, and what provide in the table is the percentage by weight of each component.The Pesticidal combination that described embodiment produces, the desinsection scope is wide, can be used for preventing and treating all insects of crops (except the soil insect), and the worm mite is double controls, and also has ovicidal action and repellent effect.Every mu of consumption is generally the 10-35 milliliter, is the 1/2-1/6 of existing import with the insecticides consumption.
Annotate 1: synergist can select following any: synergy phosphorus, Butacide, Octachlorodipropyl Ether, synergy spirit.
Annotate 2: organic solvent be following any: benzene,toluene,xylene, ethanol, benzene alcohol mixture.
Claims (3)
