Welcome to the second issue of the 1999 growing season.
Spring is an active time of growth for plants and pests.
Weather is playing a big role in that it has been unusually wet and cool for this time of year. While the cool conditions slow down pest development, the wet conditions foster a number of foliage diseases. Continue applications of fungicides for control of this fungal disease. Treatment is rarely necessary and may actually be too late already this season as trees have fully leafed out in most areas. Typical symptoms include small brown dots on infected foliage and leaf drop , often followed by larger irregular dark blotches on leaves .
