Biopesticide composition for preventing and controlling ectropis oblique

The invention belongs to the technical field of pesticide, in particular to a biopesticide composition for preventing and controlling ectropis oblique. The biopesticide composition is characterized inthat the effective component is prepared from propylene glycol alginate and azadirachtin according to a weight ratio of (1:30) to (30:1). The biopesticide composition for preventing and controlling the ectropis oblique has remarkable synergistic effect and persistent effect; the dosage of the pesticide is lowered; residue of the pesticide on the crop is lowered; environment pollution is lowered;the biopesticide is safe to human beings and livestock, is high in environment compatibility, and is not easy to produce pesticide resistance. 本发明属于农药技术领域，具体涉及种防治茶尺蠖的生物农药组合物。种防治茶尺蠖的生物农药组合物，其特征在于：有效成分包含藻酸丙二醇酯和印楝素，所述的藻酸丙二醇酯和印楝素的重量比是1:30-30:1。本发明的防治茶尺蠖的生物农药组合物具有明显增效和持效作用；减少了农药的用药量，降低了农药在作物上的残留量，减轻了环境污染；对人畜安全，环境相容性好，不易产生抗药性。
