摘要： 1,3-Dichloropropene (1,3-D) was evaluated as a potential alternative for the widely used soil fumigant methyl bromide (MeBr) in cucumber (Cucumis sativus Linn.) crops in China. Six treatments were replicated five times in a randomized complete block design: fumigation with MeBr (400 kg.ha(-1)), three 1,3-D doses (90, 120, and 180 L.ha(-1)), an avermectin dose (7.5 L.ha(-1)), and a nontreated control. Results consistently indicated that MeBr was generally superior to the treatments involving all 1,3-D and avermectin, which in turn were superior to the control, for improving cucumber yield and to control nematode and weed. In two successive seasons, 1,3-D at a dose of 180 L.ha(-1) was as effective as MeBr in increasing plant height, vigor, and yield, as well as showed excellent nematode control efficiency, but it had relatively poor potency to control weeds. The present data support the conclusion that 1,3-D is a promising MeBr alternative for managing nematodes and weeds in cucumber crops and can be used in integrated pest management programs.
