The cucumber beetle is still active. Remember to spray early in the morning for this pest before they are active and flying around. Crop rotation does a fair job with this critter if you are isolated from other growers. The problem has become evident during the last week to ten days. The disease gets its name from the fact that it causes a grey moldy growth on plant parts including fruit, leaves, blossoms and stems.
Leaves become necrotic.
At first glance, the fruit symptoms may be confused with blossom end rot, but the color is tan to grey and the affected area is not sunken as with blossom end rot. Botrytis is favored by moist, humid conditions. Recently, we have had a good deal of wet and cloudy weather which is conducive to this disease. Although the houses are fairly well ventilated, the dense plant canopy keeps the relative humidity high around the leaves. Moisture management is a key part of managing this disease.
