Obvious gain effect is served after combination in terms of the insecticidal effect of insect.By experiment also demonstrate that the two with weight ratio be 1:
After 1 proportioning is combined, rhamnolipid relatively is used alone for its insecticidal effect or nimbin insecticidal effect is obviously improved, although this is matched somebody with somebody
Compare the two be used alone gain effect it is more obvious, can economically consider, because the current manufacturing cost of rhamnolipid compared with
Height, so rhamnolipid or nimbin weight ratio are with 1:The composition of 1 proportion relation production, its production cost is still higher.
But the proportioning also makes insecticidal effect more lasting, using complete said composition desinsection after, lose within nearly 27 days on plant insect growth.
Again because of rhamnolipid and the special property of medicine of nimbin, therefore the composition of the two combination production is endangered people and animals in use
It is small, harm will not be brought to the mankind or livestock because the mankind or livestock eat by mistake.
A kind of composition of embodiment 2, including rhamnolipid and nimbin, rhamnolipid and nimbin weight in composition
Than being 1：10.This proportioning is the optimal proportion in the present invention, and this ratio can ensure that the two combination is not in that antagonism is made
With, and by after experiment, experimental result also demonstrate rhamnolipid and nimbin with weight ratio be 1：10 proportion relation knot
After conjunction, on the premise of insecticidal effect is declined to a great extent, the production cost of whole composition is but substantially reduced.The present embodiment
Proportioning selection, not only reduces the production cost of composition, and the insecticidal effect of its composition also compares exclusive use, gain
Effect is obvious.Therefore this programme is the most suitable scheme of the application, and most suitable balance is have found between insecticidal effect and production cost
Point.This programme not only good disinsection effect but also low production cost.
A kind of composition of embodiment 3, including rhamnolipid and nimbin, rhamnolipid and nimbin weight in composition
Than being 1：20.This proportioning makes the production cost of composition cheaper, and this antagonism does not occur yet, the combination of the two
There is gain effect using being also relatively used alone, the insecticidal effect of comparable proportioning before will be nothing like, such as with 1：10 this
It is individual most adaptation than compare the desinsection number of the two differed to the greatest extent 1/5th, although therefore this ratio proportioning manufacturing cost
It is low, can insecticidal effect it is unsatisfactory.But the insecticidal effect of its exclusive use of rhamnolipid and nimbin more in the prior art
Or slightly improve, and its low production cost, it may have certain economic worth.
Composition in the present invention is applied to agricultural chemicals by embodiment 4, for killing the insect such as aphid, temperature that are grown on plant
Room plant hopper, diamondback moth, cabbage caterpillar, red spider and smaller green leaf hopper insect etc., its insecticidal effect is also used alone more in the prior art

Suitable disinsection method.
A kind of disinsection method of embodiment 9, plant is sprayed on after diluting 1000 times comprising composition clear water with spraying machine
On blade face, the method low production cost, though the two is used alone more in the prior art through diluting the good disinsection effect after 1000 times,
But compared to first two method, its insecticidal effect is substantially not enough.
Experimental data：In mid-July, 2015 in Shaanxi Province Yanliang District pollution-free vegetable production base, choose middle fertility,
PH value be 6.5-8.0 between, soil property be blue mud soil vegetable field, choose 667 ㎡, averagely plantation 3000 plants of wild cabbages, it is sweet at the beginning of 10 months
Blue growing way is essentially identical, proceeds by insecticide experiment.It is 1 by the weight proportion of rhamnolipid and nimbin:1、1:10、1:20
Composition carry out the dilution of same equimultiple with the medicament that rhamnolipid and exclusive use nimbin is used alone respectively, it is then right
Wild cabbage carries out sprinkling experiment.
3 areas of experiment point, each area's area is 100 ㎡, and each area is divided into 4 cells again, and random alignment, each area is carried out
The preventive effect test of various concentrations proportioning, same equimultiple is carried out by the composition and the exclusive use of the two of rhamnolipid and nimbin
Using clear water as control after dilution, tested.Quantitative plant is randomly selected before spray carries out the record of number of pest.
Aphed population, then carries out dispenser to experimental subjects in preferably several days in weather using knapsack spraying agent, and
3rd day statistics aphid survival number situation after spray.
Drug effect computational methods：Insect population goes down=(worm amount after worm amount-medicine before medicine)/medicine before worm amount × 100%
Rectifying efficacies=(each treatment region Revision insect recluced rate-clear water control Revision insect recluced rate)/(1- clear water control insect population goes down
Rate)
It is now discovered that rhamnolipid and nimbin with weight ratio be 1:10 proportion relation is prevented through 900 times of desinsections for using of dilution
Efficiencies are optimal, and the experimental data for now providing this group see the table below：
The Pesticidal combination of nimbin and rhamnolipid test result indicate that, nimbin and rhamnolipid are 1 in weight ratio:
During 10 proportioning, it is best practice to consider as the insecticidal effect and production cost of insecticide after being diluted through 900 times.Rhamnose
Fat and nimbin are used separately as insecticide, although the desinsection preventive effect all with certain insecticidal effect such as nimbin is reachable
76.55%, and the desinsection preventive effect of rhamnolipid all has certain insecticidal effect compared to clear water control treatment up to 42.97%,
And nimbin and rhamnolipid are 1:Killing rate has averagely reached 98.35% mostly close to 100% during 10 proportioning.The two
Combine the Pesticidal combination desinsection particularly to aphid in terms of desinsection with significant gain effect, nimbin and rhamnolipid
Preventive effect has also reached extremely notable compared to the two exclusive use variance analysis.Have between rhamnolipid and the combination of nimbin obvious
Gain effect, and 1:Good insecticidal effect can be ensured when 10, the production cost of composition is significantly reduced again.
