Abstract: Toxicity determination of cypermethrin phoxim their mixtures and 25% cypermethrin-phoxim on Sucra jujuba Chu was performed by trace dropping method in the lab. According to LC_(50) and CTC of these pesticides,synergism of combined application was compared and control effect of 25% cypermethrin-phoxim was analyzed by ANOVA method. The results showed that 25% cypermethrin\|phoxim was not the best of all pesticides,but cypermethrin-phoxim was.
