Significant white mold pressure is possible in both soybeans and dry beans this season. BASF Technical Service Representative Ken Deibert gives the credit to the moisture seen this season. “Not only the subsoil moisture but we have been receiving some timely rain, heavy dews in the morning and the higher humidity that we are experiencing is certainly going to allow white mold pressure to thrive.” The fungicide application should happen when the crop is in the early R2 stage of development which coincides with row closure. Deibert also recommends the selection of a spray nozzle that will produce a medium-to-course size droplet. “They create a little bit more velocity or weight to drive those droplets into the canopy,” Deibert told RRFN. “White mold generally starts in the lowest part of the canopy when the oldest flowers start to dry down; that’s where the white mold infection enters the plant.”
