摘　　要：通过福美双、百菌清、甲基硫菌灵、代森锰锌、多菌灵等5种农药对橡胶树基腐病病原腹状镰刀菌(Fusarium venfricosum)的毒力测定结果:参试的5种药剂在产品规范的使用浓度内都有明显的抑菌效果,其中,多菌灵的抑菌效果极显著地(P﹤0.01)优于其他4种农药,其有效浓度梯度实验结果表明,在500倍至1 200倍浓度之间,抑菌效果差异不显著。Five pesticides were tested against Hevea rubber collar rot caused by Fusariumvenfricosum. There are obviously anti-bacterial effect of all tested pesticides on this disease at their normal concentration, of which carbendazim is greatly superi-or to the other ones（P﹤0.01）, and there is no obvious difference for this chemical at any concentration of 500 times to 1 200 times according to gradient experiment.
