Abstract:
A method for the control of established fungal or bacterial plant disease in or on non-dormant plant tissue without phytotoxicity to said tissue comprising applying 0.1 to 2% w/v a fatty acid, its salt or derivative, or mixture thereof, to a surface of a harvested or actively growing plant tissue that has established fungal or bacterial plant disease, the plant tissue being selected from the group consisting of citrus tissue, apple tissue, lemon tissue, pear tissue, nectarine tissue, tomato tissue, peanut tissue, grass tissue, and flower tissue, wherein the applied concentration and amount of the fatty acid, its salt or derivative are fungicidally and bactericidally effective to substantially eradicate the established fungal and/or bacterial plant disease without phytotoxicity to said plant tissue, and wherein said fatty acid, its salt or derivative conforms to the following formula: ##STR2## wherein Z=OR.sub.1 =C5 to C19 saturated or unsaturated hydrocarbonY.sub.1 =H, C.sub.1-5 hydrocarbon, or hydroxyl at any position along R.sub.1Y.sub.2 =H, C.sub.1-5 hydrocarbon, or hydroxyl at any position along R.sub.1R.sub.2 =H, K, Na, aliphatic amines which form cationic aliphatic ammonium compounds, or a C.sub.1-10 saturated or unsaturated, branched or unbranched, hydrocarbon having at least one hydroxyl group at any position on R.sub.2.
