The relative humidity of the air and the closing rate of the leaves of the ferns is an inverse relationship. The greater the humidity, the slower the leaves close because of prolonged exposure to moisture in the air. [5] Pleopeltis polypodioides can severely desiccate and lose almost all of its water. Experiments have shown it can lose up to 97 ...

The USDA’s Animal and Plant Health Inspection Service, or APHIS, has allocated more than $108,000 for a research project studying the risks of beech leaf disease in several states.
Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
