ZUO Yu-Hu1,2 HOU Ju-Mei2 KANG Zhen-Sheng1 CHEN Chang-Qing1 HUANG Li-Li (1College of Plant Protection, Northwest Agriculture & Forestry University, Yangling Shaanxi 712100; 2College of Plant Science and Technology, Heilongjiang August First Land Reclamation University, Daqing 163319)  
Phytophthora sojae developed the resistance to metalaxyl easily. The metalaxyl-resistant isolate (Mtr) of P. sojae was found in the wild-type isolates of P. sojae after treatment with metalaxyl. The resistance level of the metalaxyl-resistant isolate was over 870 times higher than that of the single zoospore progeny isolates of the wild-type parent isolate. The resistance to metalaxyl of Mtr isolate was inherited stably, and they did not show variation from the first zoospore progeny to the third zoospore progeny. The maintenance character of Mtr was not depended on metalaxyl. The resistance to metalaxyl of Mtr single zoospore isolate was not reduced and their zoospore progeny were not varied after 22-30 days growth on the metalaxyl free carrot agar medium (CA).
