Air filtration and germicidal UV keeps powdery mildew at bay

Powdery mildew is probably one of the most common and widely distributed diseases of plants in greenhouse production. This disease is responsible for significant economic losses in many greenhouse floricultural and vegetable crops.

More recently, powdery mildew has been found to be a serious threat to Marijuana production. Although infections usually do not result in plant death, they reduce the yield as well as crop aesthetics and value.

In the greenhouse, 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 UV germicidal disinfection of the airand surfaces within the greenhouse is a powerful newway to eliminate powdery mildew outbreaks.
