Application test
According to《People's Republic of China's agricultural industry criteria》The 14th part of insecticide:Leaf dipping method(NY/T1154.14-2008),
The insecticidal effect of embodiment of the present invention 1-8 and matched group 1-3 aqueous emulsions to diamondback moth is determined using leaf dipping method, is made of hot water molten
Agent, 800 times of embodiment of the present invention 1-8 and matched group 1-3 water and milk dilution agent are gathered not in contact with any medicament, without worm's ovum
Fresh cabbage leaves, are cut into diameter 3cm leaf disks, take out and dry, be then put in and be lined with filter paper after putting into the liquid immersion 10s
Culture dish(φ9cm)In, 3 are put into per ware, each leaf disk faces up placement, chooses the diamondback moth 3 basically identical into size
Instar larvae, per 15, ware, is repeated 4 times, is put into wet cotton mass moisturizing, then closes the lid, and set distilled water as blank
(CK), being placed in 25 ± 2 DEG C of constant incubators and cultivating, the death condition of test worm is observed and is recorded after 24h, worm is stirred with brush pen
Body, it is then death that polypide is motionless, and measurement result is shown in Table 1.
Mortality rate=dead borer population/test worm number × 100%;
Corrected mortality=[(Treatment group mortality rate-matched group mortality rate)/(1- matched group mortality rates)] ×100%.
Plant compound pesticide insecticidal effect testing result of 1 embodiment of the present invention 1-8 of table containing jervine
As shown in Table 1, the plant compound pesticide killing rate of embodiment of the present invention 1-8 jervine is up to more than 70%, embodiment 6
Plant compound pesticide containing jervine increases Oleum Caryophylli, enhances insecticide anthelminthic effect, and, up to 100%, contrast is real for killing rate
Apply example 1,2 and 3 and eliminate jervine, almond oil and nimbin, plant of the insecticidal effect significantly lower than the present invention containing jervine respectively
Thing compounded pesticides, therefore, plant compound pesticide formula of the present invention containing jervine rationally, make by each raw material performance Synergistic
With.
