<p>An antimicrobial composition is disclosed which is particularly useful in the protection of plants against microbial attack. The composition may also be used to treat plants that are infected with microorganisms. The composition comprises in colloidal form, an antimicrobially effective amount of a product formed by the reaction in water of a water soluble cupric tetra amine salt with an acid or a salt thereof selected from the group comprising hydroxy carboxylic acids, dicarboxylic acids, hydroxy di- and tri- carboxylic acids, polyhydric dicarboxylic acids, ketonic acids and mixtures and isomers thereof; the molar ratio of the water soluble Cupric tetramine salt (as copper) to the acid or salt thereof (as carboxylate groups) being from 4:1 to 1:4; and, a pectin in an amount of 0.05 to 2.00 % w/v and having a degree of esterification of 2-20 or derivatives or mixtures thereof. Optionally, a wetting agent to promote the wetting of the plant or parts thereof by the composition, a spreading agent to promote the distribution of the composition onto the plant or parts thereof, and an adherent to promote the retention of the composition onto the plant or parts thereof may be included.</p> |
