My understanding is that moisture availability drives secondary cycles of the population. Warmer weather won't help unless it leads to drier weather. When dry weather begins to prevail, the bacterium will cease to spread but remain systemic in the tree. Thats why its such a difficult disease to manage. Lets just hope it gets drier. For us it's the wettest Spring I can remember around Chicago. We entered June about 10" ahead of normal for the year. We have had 5" in June so far. Its raining now with rain forecasted 3 of the next 5 days.
