Since it was raining I thought this would be a good opportunity to spray some Actinovate with Iron and some Azos under the leaf canopy. Cool weather in Denver today with it only getting to about 70 degrees today. Not much rain, but a fairly constant mist throughout the day.
Acinovate is a pretty interesting biological. It is one of the few that I can think of that works in the soil and on the leaves to protect the plant. Actinovate contains a patented beneficial microbe that suppresses and helps control a wide range of diseases, including black spot on roses and the late-blight that tomatoes can get. I particularly like to apply Actinovate to the leaves of my pumpkin plants around the first week of August. You will get a lot less powdery mildew if you apply at that time and at the beginning of September.
