Abstract : Copper application with the pulsFog® was compared to copper application with conventional hand guns. Copper count N (copper ammonium carbonate) was the copper source. Trees were sprayed (solution: 300 ml Copper count N/100 litres water + 6 ml/100 litres Agral 90) or fogged (solution: 2.5 litres Copper count N + 2.5 litres Dillad oil + 5 litres water) every 28 days from Oct. 1, 1997 until Feb. 19, 1998. Dense Heidi mango trees, and Kent mango trees spaced at 3 × 3 m, were used. Fogging was as effective as conventional hand-gun spraying in controlling disease (anthracnose [Glomerella cingulata] and soft brown rot [Nattrassia mangiferae]). The pulsFog is considered to have specific application in high density orchards, trees with exceptionally dense canopies, and trees situated on terrain which is inaccessible to conventional spraying equipment.
