Abstract
The invention relates to phytochemical pesticide synergistic agent. The pesticide synergistic agent takes compositae ill weeds eupatorium adenophorum as raw material. The eupatorium adenophorum is dipped in definite organic solvents for 7 to 10 days, and then is squeezed to get extract which contains 'euparin'. The euparin is added in to chemical pesticides by volume percent of 1-95%, has obvious synergies. When the control efficiency is same, the phytochemical pesticide synergistic agent can reduce the use of pesticides by 30-60 %, reduce the negative effects of pesticides on environment, reduce the use cost of pesticides, and reduce the burden of farmers. The ill weeds eupatorium adenophorum is used as raw material, which controls ill weeds eupatorium adenophorum and changes waste to valuable, thus increasing the income of hill farmers.
Description
Technical field
The present invention relates to agricultural insecticide, particularly relate to a kind of plant insecticide synergist that can improve the known insecticides drug effect.
Background technology
The Application and Development of plant insecticide synergist can be botanical pesticide research both at home and abroad in the future and opens up another approach, also can be between botanical pesticide and the excellent chemical agricultural chemicals and learns from other's strong points to offset one's weaknesses mutually, searches out the doulbe-sides' victory approach of science.New plant resource active matter and high-efficient low toxicity insecticide are used product with, after obtaining the Pesticidal products registration, can be widely used in the control of insect of vegetables, fruit, tea and cereal crops,
In order to reduce the pollution of chemical insecticide to environment, various countries all drop into the insecticide of the new high activity of huge fund: A. exploitation, low toxicity, low-residual in pesticide manufacturing; B. develop biological source insecticide; C. develop insecticidal synergist.With regard to insecticidal synergist exploitation, make progress these years limited, and developed synergist itself with high costs, can only in the laboratory, use, can't the large-scale application popularization.
Summary of the invention
The object of the present invention is to provide a kind of raw material sources wide, both administered the malignant weed Eupatorium adenophorum, can turn waste into wealth again and increase income for hill farmer.Preparation is easy, and effective, cost is low, multiple insecticide is had the plant resource broad spectrum pesticide synergist of synergistic effect.
The present invention achieves the above object by the following technical programs: a kind of plant insecticide synergist, with composite family malignant weed Eupatorium adenophorum is raw material, after soaking 7-10 days with certain organic solvent, contained the extract of " euparin " through squeezing, should " euparin " be the plant insecticide synergist.
With composite family malignant weed Eupatorium adenophorum is raw material, and after it was pulverized, after 7-10 days, the extract through squeezing obtains was " euparin " with certain organic solvent immersion.
With after the raw material pulverizing with after 95～99% alcohol immersion 7-10 days, the extract through squeezing is obtained is " euparin ".
Described " euparin " using method: the ratio of percentage 1～95% by volume joins described " euparin " in the chemical insecticide.
With this extract by volume the ratio of percentage 30～60% to join in the chemical insecticide synergistic effect the most obvious.
Chemical insecticide of the present invention should be hydrophilic compound, and promptly formulation should be aqua, aqueous emulsion or suspending agent.
" euparin " of the present invention is meant the general name of the cauline leaf that the intense stimulus smell the is arranged extract after alcohol immersion that obtains from the overground part branch of Eupatorium adenophorum plant.According to Eupatorium adenophorum be the analysis showed that, there is the intense stimulus odoring substance that kind more than 100 is arranged on the Eupatorium adenophorum, mainly contain right-cymol, sequiterpene and derivative compound thereof, monoterpene and derivative compound thereof, triterpenes, steroidal, flavonoids, nopinene and citrene etc.
When the present invention adopts the ethanol equal solvent to extract " euparin ", be after the Eupatorium adenophorum plant of field acquisition is pulverized, add 1～3 times solvent, soak and frequent the stirring, after 7-10 days, promptly get the extract that contains " euparin " with draining the method squeezing.Should " euparin " be plant insecticide synergist of the present invention.
Outstanding effect of the present invention is:
When " euparin " adds in certain insecticide, under equal control efficiency, can reduce this insecticide consumption 30～70%, and the cost of " euparin " is the part slightly higher than the cost of organic solvent, accounts for 20～30% of insecticidal total cost.Therefore, adopt the present invention both can effectively administer this unmanageable malignant weed of Eupatorium adenophorum, turn bane into boon, can reach again and reduce the agricultural chemicals use cost, reduce the purpose of chemical pesticide consumption.
Of the present invention applying can be reduced on a certain crop chemical pesticide consumption more than 30%.Thereby significantly reduce the input amount of insecticide, thereby alleviate the extent of injury of insecticide environment.
