The efficacy of several methods of fosetyl-Al application to control avocado stem canker disease, caused by Phytophthora citricola, was evaluated under greenhouse conditions. Fosetyl-Al wasw applied to the canker area as paint alone (0.4 g a.i. fosetyl-Al + 1.0 ml water), combined with Tree Seal (0.4 g a.i. fosetyl-Al + 0.5 ml water), or applied alone followed by Tree Seal on either scraped bark or bark cut in a fish-scale-like pattern (30 cm along the stem). The use of fosetyl-Al as a soil drench (3.2 g a.i. fosetyl-Al per liter) was also evaluated. The most effective method was either using the fosetyl-Al: Tree Seal:water formulation on heavily scraped areas of the stem of applying fosetyl-Al alone on the bark cut in a fish-scale-like pattern. Applying fosetyl-Al as a soil drench was also effective in controlling stem canker disease, but to a lesser degree than the paint application method. Phosphonate, the anionic metaboliter of fosetyl-Al in plants, was quantified in the bark, leaves, and roots of treated avocado plants by high-performance liquid chromatography following the different application methods of fosetyl-Al. Application of the fosetyl-Al: Tree Seal:water formulation on heavily scraped stem areas resulted in the highest level of phosphonate residue in the canker area and was the most efficacious in controlling the stem canker pathogen. Phosphonate residue in the plant inhibited infection by P. citricola for about 6 months after its application. |
