Abstract
Fosetyl-Al applied as a foliar spray and a drench, metalaxyl as a granular broadcast and drench, and Enterobacter aerogenes as a drench were evaluated for 3 yr at three sites for control of crown and root rot, caused by Phytophthora cactorum, in naturally infected apple trees. All chemical and biological treatments reduced crown and root rot disease ratings of apple trees. This indicates that these treatments have the ability to arrest further symptom development in naturally infected trees if they are treated as soon as symptoms appear. Fosetyl-Al as a drench and metalaxyl as granular broadcast significantly reduced death of trees infected with crown and root rot in orchard 1 (.)
