Abstract
A compound insecticide for controlling the pests of cotton, vegetables, paddy rice and fruit tree is prepared from imidacloprid, BPMC, emulsifier and solvent through stirring at 20-40 deg.C for 40-60 min, and features high safety and effect, low residue and distinct synergistic action to kill plant hopper.
Description
The present invention relates to chemical insecticide, specifically is a kind of chemical insecticide that is mixed by principal component.
Rice fulgorid is to migrate in a kind of big zone, has fulminant and paroxysmal insect, be the area maximum takes place in the many insect pests of China paddy rice, and the heaviest insect of causing harm, when it broke out, non-chemically control could not.In China, isoprocarb once was the first-selected agricultural chemicals that many peasants prevent and treat this worm, but the isoprocarb lasting period short (3～5 days), a dispenser can not be controlled causing harm of whole rice fulgorid in season.The Buprofezin of promoting the use of in recent years (buprofezin) hold imitate and preventive effect all good, but drug effect is slow, dispenser 3～7 talent's demonstration control efficiency, and adult do not had direct killing power.Owing to use Buprofezin continuously, rice fulgorid has produced low the grade to the medium level resistance to it.
The object of the present invention is to provide a kind of chemical insecticide composition that can effectively prevent and treat the resistant rice plant hopper with and preparation method thereof.
In agricultural insecticide, selectively with two or more pesticide compositional or be mixed, be the control resistant insect, enlarge insecticidal spectrum, improve effective way of preventive effect and one of levy.Two or more insecticides are used with, synergy, addition and three kinds of results of antagonism may occur, and the discrimination standard of synergistic effect are that co-toxicity coefficient is obviously greater than 100.
The scheme that the object of the invention is implemented, use above-mentioned theory just, adopt mixture screening technique---the co-toxicity coefficient determination method of generally acknowledging both at home and abroad, indoor rice fulgorid is carried out the screening of mixture prescription after, draw a kind of novel pesticide that mixes in proportion by Imidacloprid and Bassa.
The molecular structural formula of Imidacloprid of the present invention is as follows:
Molecular formula: C
9H
10ClN
5O
2
Molecular weight: 255.7
The molecular structural formula of Bassa of the present invention is as follows:
Molecular formula: C
12H
17NO
2
Molecular weight: 207.3
Insecticide of the present invention also can contain emulsifier and solvent, the preferred toluene of described solvent.
Preferred following each component (weight, part) assembly in proportion of insecticides of the present invention: Imidacloprid 0.1～10, Bassa 5～40, emulsifier 8～15, solvent 35～86.9.
Method for producing insecticide of the present invention is: be metered into Imidacloprid, Bassa, emulsifier and solvent respectively in retort (or blender), fully stirred 40～60 minutes under 20～40C condition, promptly make insecticide of the present invention.
In the component that the present invention selects for use, Imidacloprid cost height, the virulence height, the lasting period is long; The Bassa insecticidal action is fast, holds to imitate weak point, and cost is low.After assembly, both can learn from other's strong points to offset one's weaknesses, and make that insecticide has both synergy, the longevity of residure is long, virulence is high, can reduce the person poultry toxicity again, characteristics such as reduce cost.Through adopting co-toxicity coefficient determination method measurement result to show that co-toxicity coefficient of the present invention is 188, has extremely significant synergistic effect.Insecticide of the present invention except to rice fulgorid effectively, also can be used for killing other insect.
Insecticide of the present invention is owing to have obvious synergistic effect, therefore the consumption of each component is starkly lower than the consumption of two compositions when using separately in the composition, can obviously reduce selection pressure to each composition, help delaying drug resistance, rice fulgorid is slowed down greatly to the speed that above-mentioned two kinds of compositions produce multiresistance.
The present invention is further described below in conjunction with embodiment, but do not limit the present invention.
Embodiment 1:
In blender, add 690 parts of toluene successively, 10 parts of Imidacloprids, 200 parts of Bassas, 100 parts in agricultural emulsifier 0204C and 2201 mixture.After stirring 50 minutes under 30 ℃, get product.
Embodiment 2:
In blender, add 630 parts of toluene successively, 50 parts of Imidacloprids, 200 parts of Bassas, 120 parts in agricultural emulsifier 0204C and 2201 mixture are put into hold-up tank at 40 ℃ after stirring 40 minutes down, and the metering packing makes 1000 parts of finished products.
Embodiment 3:
In blender, add 350 parts of toluene successively, 100 parts of Imidacloprids, 50 parts of Bassas, 80 parts in agricultural emulsifier 0204C and 2201 mixture are put into hold-up tank at 20 ℃ after stirring 60 minutes down and are got product.
Embodiment 4:
In blender, add 800 parts of toluene successively, 1 part of Imidacloprid, 400 parts of Bassas, 150 parts in agricultural emulsifier 0204C and 2201 mixture are put into hold-up tank at 35 ℃ after stirring 5 minutes down and are got product.
Embodiment 5:
In blender, add 550 parts of toluene successively, 300 parts of Imidacloprids, 20 parts of Bassas, 130 parts in agricultural emulsifier 0204C and 2201 mixture are put into hold-up tank at 30 ℃ after stirring 50 minutes down and are got product.
