Abstract
A systemic fungicide and method of application to trees subject to the Dutch elm disease fungus and other fungus diseases wherein the fungicide material used is a water-soluble derivative of methyl-2-benzimidazole carbamate (BCM) and the method of introduction is a positive pressure root injection method. Examples of the water-soluble derivatives are chloride, sulphate, phosphate, nitrate, and sodio derivatives of BCM. The injection method is achieved by severing one or more roots below ground level and applying the fungicide solution to the severed root end under pressure via suitable tubulation.
