Through the field test and indoor research for about 3 years, it was found that the occurrence of cotton Fusarium wilt had close relationship with the climate condition in Xinjiang. when temperature was about 20℃, disease index developed very quickly. when temperature was above 24℃, disease index would reduce. With temperature dropping by the end of July and at the beginning of August, disease index would raise again.

通过田间试验和室内研究发现，新疆棉花枯萎病的发生与气候有十分密切的关系，在地膜植棉的情况下，当气温达20℃左右病指上升最快，气温达24℃以上则很快进入高温隐症期；7月下旬或8月上旬随温度下降，病情又有回升，故枯萎病在新疆也有两个明显的高峰期，只不过因地膜植棉发病期明显提前而已。
