Phosphorus, nitrogen and potassium nutrition on Calonectria leaf blight in eucalypt plants

Forest Pathology, 2019
AbstractCalonectria pteridis causes Calonectria leaf blight (CLB), and consequently severe defoliation in eucalypt plantations, which results in losses in wood volume. To reduce the negative impacts of this disease in eucalypt, this study aimed to assess the application of different doses and combinations of the macronutrients N, P and K on the ...
