The management of soybean rust (SBR) caused by the obligate fungus mostly relies on the use of synthetic fungicides, especially in areas where the disease inflicts serious yield losses. The reliance on synthetic fungicides to manage this disease has resulted in resistance of populations to most fungicides. In this study, bacteria isolated from diverse environments were evaluated for their biocontrol potential against using soybean detached-leaf method and on-plant in the growth chamber, greenhouse, and field.

The objective of this study was to determine the effect of selected biopesticides and their application time on reducing SBR infection. There were differences ( < 0.

Strategies to manage SBR include the use of foliar fungicides. Fungicide types, the rate of product application, and the number and timing of applications are critical components for successful rust management.

Because desert citrus production in California can occur in proximity to table grape production, it was suspected that fungi associated with grapevine cankers might also be associated with citrus branch canker and dieback decline. To determine the fungi associated with branch canker and dieback disease of citrus in the southern California desert regions, surveys were conducted from 2011 to 2013 in the major citrus-growing regions of Riverside, Imperial, and San Diego Counties.
