Abstract

This paper adopts growth rate method to launch indoor measurement on the inhibitory effect of 8 kinds of bactericide on Hylocereus undulatus Britt scab original bacteria. The results show that: these 8 kinds of bactericide have relatively good antibacterial effect in high concentrations. The best effect is found in 40% flusilazole and 20% difenoconazole and the others are 25% prochloraz, 50% propiconazole, 80% carbendazim, 50% iprodione, 12.5% myclobutanil and 20% kresoxim-methy in order. The EC50 is 0.07, 0.07,0.10, 0.15, 0.28, 0.42, 0.78 and 12.30ppm in order.
