“Beautiful” might be the last word a grower would use to describe powdery mildew. BUT it’s a fitting description for these electron photos from Dr. Zamir Punja’s presentation at CannMed 2018 about cannabis diseases.
Great talk… wish I was there to hear the entire presentation. At MJ BIz there was a company that was doing radiation remediation. Ben, did he mention anything about that? Just curious?
Powdery mildew is very easy to control with Oxine WT. Dose on a regularly scheduled basis into your greenhouse irrigation system as well as treat the incoming water to your humidifiers.
