A schematic description of the possible role of Trichoderma asperellum strainT34 and potassium phosphite solution KPHI against P. cubensis, the causal agent of cucumber downy mildew disease. Briefly, the foliar application with T34 and KPHI reduce the disease development of cucumber downy mildew disease under greenhouse conditions. This might be due to the activation of enzymatic antioxidant mechanisms (CAT, POX, and PPO) of infected cucumber plants. In addition, decrease the % electrolyte leakage and collapse the sporangiophores of P. cubensis. Finally, T34 and KPHI might promote the growth of P. cubensis-infected cucumber plants and enhance their yield parameters because of reduced disease severity. Elevated levels are indicated by an up arrow and lowered levels by a down arrow. Go to the main text for more information.
