摘要
The mycelium growth and sporulation in different temperature,pH value and light conditions were detected by using the crossing and haemocytometer method. The toxicity of five fungicides to Fusarium oxysporum was tested by mycelia growth method, so as to provide the reference for prevention and control against F. oxysporum. The optimum temperature and pH value of F. oxysporum to grow and spore were 28 ℃ and 6-7. Alternating light and darkness promoted growth and sporulation of bacterial colony. As for five fungicides,the EC50of tebuconazole was 10. 02 mg·L- 1,92. 50 times as much as carbendazim. The EC50of myclobutanil and Fuxing was 91. 23,96. 68 mg · L- 1,respectively. Tebuconazole showed the most tremendous inhibitory effect and control efficiency on F. oxysporum.
