Kentucky Extension and Research IPM Priorities
Corn Foliar diseases in corn-after corn are not ravaging yields but with the vastly increasing interest in fungicides on corn, this is a major issue that needs more attention.
Fungicide management and timing of applications, value of fungicides, and effective use of fungicides for disease control.

Bacterial leaf scorch of landscape trees is a growing problem and homeowners and municipatities throughout Kentucky are losing huge amounts of money, property value, carbon sequestration, and energy savings due to this scourge of urban forests. Little is known of the insect vector relatonships for this disease and it seems likely that until the insect biology in relation to bacterial leaf scorch is understood, little progress in disease management will occur.
