Abstract：Experiments were carried out for controlling Aphis gossypii Glover of cucumber with lignite extract in greenhouse.The results show that lignite extract with dosage of 10.5-21.0 L·hm-2 which sprayed with high power electrostatic spray system every 6-8 days can significantly reduce the quantity of Aphis gossypii Glover.Lignite extract with dosage of 21.0 L·hm-2 can make the quantity of Aphis gossypii Glover maintain extremely low lever in cucumber growth period.
