番茄叶霉病菌分生孢子萌发的最适温度为２５℃，最适ｐＨ值为４０～５０。相对湿度小于８６％时孢子不萌发，病菌在ＰＳＡ培养基上产孢量最大。分生孢子的致死温度为４５℃５ｍｉｎ，孢子可在地表或浅土层中的病残体上越冬。
The optimum temperature for the conidia germination of Fusarium solani was 25 ℃ and the optimum pH value was 4 0 ~ 5 0. The spores did not germinate when the relative humidity was less than 86%, and the spores germinated the most on the PSA medium. The lethal temperature of conidia is 45 ℃ for 5 minutes. The spores can overwinter on the sick or dead in the surface or shallow soil.
