Eastern Kansas
Chemical supplier suggested crop oil concentrate to use with Prefix and Rup post on beans. However, the UNL crop guide specifically says: "Add non-ionic surfactant at 0.25% v/v to the final spray volume. Do NOT use crop oil concentrate when applying Prefix post-emergence as these spray adjuvants may increase soybean injury."
Does anyone have any experience or recommendation either way? Thanks.
