NOVELTY - Treating infestation of a plant or its progeny by a phytopathogenic microorganism involves applying a metal chelate or a metal salt containing metal ions and a hydroxy analog of methionine to the plant.    USE - For treating infestation of a plant (where plant is selected from corn, cereals, barley, rye, rice, vegetables, clovers, legumes, soybeans, peas, alfalfa, wheat, sugar cane, sugar beets, tobacco, cotton, rapeseed, sunflower, safflower, and sorghum) or its progeny or plant part (where plant part selected from leaf, vascular tissue, flower, root, stem, tuber, seed, and fruit) by a phytopathogenic microorganism (such as bacteria, fungi, and yeast); for treating a foliar fungal disease of a legume plant (all claimed); for preventing microbial infestation of the seed; for treating alfalfa plant diseases such as root rot (Phytophora medicaginis and P. megasperma), rice plant diseases such as rice blast (Pyricularia oryzae), Bakanae disease (Gibberella fujikuroi), oat plant diseases such as crown rust (Puccinia coronata), barley plants diseases such as powdery mildew (Erysiphe graminis), wheat plants diseases such as powdery mildew (Erysiphe graminis), corn plants diseases such as damping-off (Pythium debaryanum), diseases of rye diseases such as purple snow mold (Fusarium nivale), potato plants diseases such as late blight (Phytophthora infestans), tobacco plants diseases such as downy mildew (Peronospora tabacina), sugar beet diseases such as leaf spot (Cercospora beticola), kidney bean diseases such as gray mold (Botrytis cinerea), broad bean diseases such as powdery mildew (Erysiphe polygoni and Sphaerotheca fuliginea) and diseases peanuts such as Ascochyta spot (Mycosphaerella arachidicola).    ADVANTAGE - ADVANTAGE u The method is environmentally safe and cost affordable; is highly effective for controlling a broad spectrum of plant microbes, such as fungi, yeast and bacteria; prevents pathogenic infestation of multitude of plants; and prevents microbial infestation of the seed.
