Abstract:
Copper fungicides applied via low head sprinklers, reduced brown rot (caused by Phytophthora spp.) on oranges and grapefruit. The most effective fungicide was Bordeaux mixture, which reduced the disease rate to the same level as that obtained by standard spraying with this fungicide. Copper oxychloride was moderately effective and captan was ineffective. A field method for brown rot rating was devised. © 1978, Springer Science + Business Media B.V.. All rights reserved.
