As can be seen from Table 8, product of the present invention has good preventive effect to prodenia litura, and better, visible than the control efficiency of single purslane extract and aconite extract, has synergistic function between product compositions of the present invention.And the preventive effect of the product adopting common extracting method to make is apparently higher than extracting separately rear blended product, visible common extraction contributes to improving dissolution rate, raising insecticide efficiency.In addition, have no during dispenser and have poisoning to show to crop.
Test example 4 the present invention contains the efficiency test of the composition pesticide cabbage pieris of kitchen garden and aconite extract
Product MW-01 ~ MW-12 of the present invention is used for preventing and treating cabbage pieris.This test 12 medicaments, 2 single doses, 1 blank, repeats for three times, Gong45Ge community.Minizone and surrounding all leave isolation strip, plot area 10m 2, community respectively processes randomized arrangement.
Be 50ppm by reagent agent thin up to activity component concentration, spray application to plant blade face, so that water membrane to appear in blade face, not lower of liquid is advisable.
Be fixed the cabbage caterpillar quantity statistics alive of blade before the test and listing mark.Within 5 days after dispenser, investigate and record the dark greyish green borer population alive on each blade.Calculate Revision insect recluced rate and preventive effect, calculate and adopt following formula:
Ta: the individual amount of survival after treatment region control; Tb: the individual amount of survival before treatment region control
Ca: the individual amount of survival after the control of check plot; Cb: the individual amount of survival before the control of check plot
Each group is repeated meter of averaging, and calculate Revision insect recluced rate and preventive effect, its result is as shown in table 9.
