Abstract
The present invention provides an effective method for controlling foliage and root fungus infection in cultivated crops. A fungicide composition in the form of an aqueous formulation which is applied to pre-harvest crops contains ingredients such as propiconazole, sodium bicarbonate, potassium bicarbonate, sodium oleate, sodium caprylate and xanthan gum. The combination of sodium oleate, sodium caprylate and xanthan gum functions as an effective spreader-sticker medium for forming an adherent coating on plant foliage surfaces, and for saturating ground soil. The coating exhibits both immediate and long duration fungicidal activities.
Claims21
A method for controlling fungal disease in cultivated plants which comprises contacting the plant matter with a fungicidally effective application of an aqueous formulation which has a content comprising (1) between about 0.1-2 weight percent of an ingredient selected from the group consisting of alkali metal and ammonium bicarbonates;
- (2) between about 0-1 weight percent of a basic ingredient selected from the group consisting of alkali metal and ammonium carbonates;
- (3) between about 0.05-2 weight percent of propiconazole;
- (4) between about 0-1 weight percent of a surfactant ingredient;
- (5) between about 0-0.25 weight percent of a hydrotrope ingredient selected from the group consisting of alkali metal and ammonium C.sub.7 -C.sub.10 fatty acid salts;
- and (6) between about 0-0.5 weight percent of a hydrophilic polymer ingredient;
- based on the formulation weight.
A fungicide composition which is a dry blend formulation comprising (1) between about 1-20 parts by weight of an ingredient selected from the group consisting of alkali metal and ammonium bicarbonates;
- (2) between about 0-10 parts by weight of an ingredient selected from the group consisting of alkali metal and ammonium carbonates;
- (3) between about 0.5-20 parts by weight of propiconazole;
- (4) between about 0-10 parts by weight of a surfactant ingredient;
- (5) between about 0-2.5 parts by weight of a hydrotrope ingredient selected from the group consisting of alkali metal and ammonium C.sub.7 -C.sub.10 fatty acid salts;
- and (6) between about 0-5 parts by weight of a hydrophilic polymer ingredient.
