Abstract

SYNOPSIS Avocado root rot caused by Phytophthora cinnamomi Rands was controlled by phosetyl-Al and phosphorous acid. Boric acid and potassium aluminium sulphate injections improved tree condition in a five-year trial, although no significant improvement could be detected in an 18-month trial. Trees injected with potassium hydroxide responded positively and less roots were infected with P. cinnamomi. Trees injected with hydrogen peroxide, hypophosphorous or dibasic-ammonium phosphate did not improve significantly.
