Test case 1
Drug effect to aphid on embodiment 1-7 tuber of stemona capsicum insecticide progress preventing and treating citrus is tested.
Experimental field：The a certain citrus orchard in northeast, on the occasion of mid-July, orange caterpillar outburst.
Reagent agent：Aerosol bomb obtained by embodiment 1-7.
Controlling object：Orange caterpillar.
Experimental design：Set 8 groups, respectively embodiment 1-7 test group and blank control group, every group of area is about
100m2Square, containing 9 mandarin trees (3 rows × 3 row), protection row, protection behavior 3m are left between every group.Test group makes respectively
With embodiment 1-7 insecticide 10kg, even spraying, blank control group sprays 10kg water.Respectively at the 1st after dispenser, 3,7,
Residual worm amount is investigated within 14 days, prevention effect is calculated using following equation：
Insect population number × 100% before Revision insect recluced rate (%)=(insect population number after insect population number-medicine before medicine)/medicine
Concrete outcome is shown in Table 1.
Table 1：Orange caterpillar prevents and treats result table
In test case, the Revision insect recluced rate of blank control group is negative, represents insect population number in increase, does not decline.Implement
Example 1-7 is effectively reduced insect population number, especially embodiment 1, started within the 3rd day after administration, medicine using the insecticide of the present invention
Effect is obvious, and compared with embodiment 2-4, embodiment 1 has used soybean lecithin 1kg, hydrolecithin 1kg, Nekal BX
The wetting agent that 1kg is mixed, any of which wetting agent is omitted than embodiment 2-4, better, is illustrated between several wetting agents
Technique effect with Synergistic.Compared with embodiment 4-7, embodiment 1 has been used by sanguinarine 1kg, cyanidenon
The stabilizer that 1kg, bergapten 1kg are mixed, any of which stabilizer is eliminated than embodiment 5-7, better,
Illustrate the technique effect with Synergistic between several stabilizers.And the insecticide of embodiments of the invention 1 after administration
14 days, still there is a significant effect, and embodiment 5-7 insecticide the 14th day after administration, insecticidal effect has declined, may
It is relevant that drug resistance is generated with part aphid.
Test case 2
Aphid progress stability test on preventing and treating citrus is carried out to embodiment 1-7 tuber of stemona pepper spray insecticide.
After embodiment 1-7 tuber of stemona pepper spray insecticide lucifuge normal temperature sealed type storage 12 months, test to aphid
Prevention effect.
Experimental field：The a certain vegetables experimental plot in northeast, on the occasion of mid-August, vegetable aphid outburst.
Controlling object：Vegetable aphid.
Experimental design：Set 8 groups, respectively embodiment 1-7 test group and blank control group, every group of area is about 50m2
Square, containing vegetables (10 rows × 10 row).Test group uses embodiment 1-7 insecticide 6kg, even spraying, blank respectively
Control group sprays 6kg water.Respectively at the 7th after dispenser, investigate residual worm amount within 14 days, using following equation calculate prevention effect：
Insect population number × 100% before Revision insect recluced rate (%)=(insect population number after insect population number-medicine before medicine)/medicine
Concrete outcome is shown in Table 2.
Table 1：Vegetable aphid prevents and treats result table
In test case, the Revision insect recluced rate of blank control group is negative, represents insect population number in increase, does not decline.Implement
Example 1-7 is effectively reduced insect population number, especially embodiment 1, started within the 7th day after administration, medicine using the insecticide of the present invention
Effect is obvious, and compared with embodiment 2-4, embodiment 1 has used soybean lecithin 1kg, hydrolecithin 1kg, Nekal BX
The wetting agent that 1kg is mixed, any of which wetting agent is omitted than embodiment 2-4, better, is illustrated between several wetting agents
Technique effect with Synergistic.Compared with embodiment 4-7, embodiment 1 has been used by sanguinarine 1kg, cyanidenon
The stabilizer that 1kg, bergapten 1kg are mixed, any of which stabilizer is eliminated than embodiment 5-7, better,
Illustrate the technique effect with Synergistic between several stabilizers.And the insecticide of embodiments of the invention 1 after administration
14 days, still there is a significant effect, and embodiment 5-7 insecticide the 14th day after administration, insecticidal effect has declined, may
It is relevant that drug resistance is generated with part aphid.
It can be seen that, stored 1 year under the conditions of normal temperature lucifuge, tuber of stemona pepper spray insecticide of the invention still has good desinsection
Effect, stability is good.Especially embodiment 1 has used soybean lecithin, hydrolecithin, the wetting of Nekal BX compounding
Agent and sanguinarine, cyanidenon, the stabilizer of bergapten compounding, stability are more preferable.
