Abstract
A coating composition for application to tree wounds, such as pruning wounds of living trees is provided. The composition is non-phytotoxic and provides extended protection against fungal pathogens. The coating composition comprises a liquid carrier together with a fatty acid metal salt active ingredient. Exemplary fatty acid metal salts include those prepared from alpha monocarboxylic acids having from 4 to 18 carbon atoms and a compound containing a metal selected from the group consisting of calcium, copper, iron, magnesium, and zinc. Various additives can be included within the composition, including gum-like substances and binders suitable to facilitate the adhesion of the active ingredient to the tree surface, as well as defoaming agents and other formulation enhancing agents.
Claims3
A non-phytotoxic fungicidal coating composition for application to wounds on living trees, consisting essentially of:
- 0.5 to 10% by weight of a fatty acid metal salt ingredient selected from the group consisting of
- calcium salt of an alpha monocarboxylic aliphatic C.sub.8-12 acid,
- iron salt of an alpha monocarboxylic aliphatic C.sub.8-12 acid,
- copper salt of an alpha monocarboxylic aliphatic C.sub.8-12 acid,
- zinc salt of an alpha monocarboxylic aliphatic C.sub.8-12 acid, and
- mixtures thereof, the fatty acid metal salt ingredient being substantially insoluble in the composition and remaining suspended in the composition;
- 0. 1 to 2% by weight of a thickening agent, selected from the group consisting of guar gum, xanthan gum, cellulose-based gum, Elemi tree gum, acacia gum, Bentonite clay, magnesium aluminum silicate, gelatin, agar, and mixtures thereof;
- and
- water;
- wherein the coating composition has a pH in the range of about 4 to 10, and is in the form of a non-phytotoxic liquid suspension or a non-phytotoxic spreadable paste.
