Diagnosing Abiotic Disorders in the Greenhouse

Problems can arise in greenhouse production that may involve living (biotic) and nonliving (abiotic) factors. Oftentimes, biotic factors present themselves clearly, especially when the causal agent is an insect pest, but plant diseases are a little more difficult to identify. Abiotic factors pose difficulty in accurate diagnosis. Visual diagnosis is a popular monitoring tool; however, using a plant diagnostic lab to identify the source of nutritional problems is still the best way to ensure accurate diagnoses because many nutritional, physiological, insect and disease problems can mimic each other. This article features some of the common abiotic disorders along with a nutritional- disorder guide to assist plant producers.
