How To Identify and Control Cercospora on Cannabis Plants

How To Identify and Control Cercospora on Cannabis Plants Professor DeBacco Cercospora Identification Starts as small yellow flecks, developing into lesions which turned to light tan or white, with yellow halos, and in severe cases developing chlorosis, leading to defoliation. The infections began on older leaves and moved through the canopy. General Conditions the Fungus Pathogen survives mainly in plant debris as desiccation-resistant pseudostromata, but can also survive as conidia in debris or seeds. When moisture is sufficient, new conidia are formed and spread via rain-splash or wind to new leaves or plants. Optimum conditions are 77° to 95° F with night temperatures above 61° F, and a relative humidity of 90-95%. Infection is greatly reduced or nonexistent at temperatures less than 59° F or during periods of leaf wetness less than 11 hours.
