The Most Effective and Economical way to Prevent Powdery Mildew

Powdery Mildew is one of the most common and widespread distributed diseases of plants for indoor and outdoor production. This disease is responsible for significant economic losses in many floricultural and vegetable crops. More recently, powdery mildew has been found to be a serious threat to Cannabis production. Although infections usually do not result in plant death, they reduce the crop consistency, yield, aesthetics, and value. In many cases, infected plants will have to be destroyed. For an indoor Cannabis grower, powdery mildew tends to be more problematic in the spring and fall when day-night temperatures favor high relative humidity, but it can develop at any time during any production cycle. An understanding of the disease cycle, organisms involved, and factors that favor disease development will contribute to successful management of this disease. Experience has proven that adequate air filtration combined with high intensity UV-C germicidal air disinfection within the grow facility is a powerful new way to prevent Powdery Mildew outbreaks.
