If you haven’t already applied a fungicide to your soybean acres, it may be time to consider it, as white mould and septoria are already surfacing in fields across the country. And proper timing is essential.
“What we’ve seen for the most economical yield response is at that R2.5 stage, or at that early pin bean stage,” says BASF’s Rob Miller, on timing fungicide applications for septoria. “So once you see a pod about 1/2″ in length, anywhere on the soybean plant — that is the optimal timing when you want to target those fields that don’t have a history of white mold.”
Besides managing disease threats, some fungicides may also provide a bit of a yield bump. In this episode of the Soybean School, Bernard Tobin talks to Miller about the critical timing for white mold and septoria, the importance of proper coverage and groundspeeds and that Priaxor yield bump we’ve heard so much about.
