We’re moving into prime white mould season — mid-summer and into August. While conditions were very favourable for disease development through June (wet and cool), mid-to-late July’s heat and dry conditions could have slowed progress of the disease.
While you won’t be able to gauge infection levels in soybeans without scouting (hint: go do that now and every few days), there are some longer term factors at play when getting a handle on this disease as a year-over-year threat.
In this latest edition of the Agronomy Geeks Ontario podcast, RealAgriculture’s Bern Tobin asks Horst Bohner, Ontario’s provincial soybean specialist what big corn yields, a cold winter and zero-tillage all have to do with white mould’s occurrence, development and suppression.
Does zero-till mean higher or lower levels of white mould? What does the long-term trend to 200, 250 or even 300 bushels per acre of corn mean for soybean planting? Are we passed the point of a one-pass fungicide application and squarely in to a two-pass cycle? A discussion on that, plus answers, in the interview below.
