Asparagus – Summer foliar diseases in Asparagus have been reported. With the cooler weather and all the rain we’ve have been experiencing on and off all summer disease pressure in asparagus is higher than normal. See article from 9/4/13 for more information.
Basil downy mildew remains active – All basil growers should scout on a daily basis and should add a labeled downy mildew specific fungicide to their weekly fungicide program. Phosphite fungicides (FRAC code 33), such as Prophyt, K-Phite, and Rampart have shown the best efficacy in trials at RAREC. Actinovate (OMRI- approved) is also labeled for downy mildew control. Please remember, all abandoned basil fields should be worked under immediately after last harvest to kill the foliage! Abandoned fields left unattended after use will only serve as a source of inoculum for other fields.
