Efficacy of OMRI-Approved Products for Tomato Foliar Disease Control

Abstract

Five materials approved by the Organic Materials Review Institute (OMRI) were tested for control of foliar diseases of tomato on an organic farm in western NY. Trials were conducted during the 2001 and 2001 growing seasons. Both seasons were exceptionally hot and dry, and disease pressure was light. Under these conditions, five of the treatments resulted in disease levels significantly different from the controls during at least one season.
