When it comes to plant development and yield potential, Ontario’s corn crop is all over the map.
With pollination quickly approaching, many growers are now wrestling with fungicide strategies for a highly variable crop.
In this episode of RealAgriculture Corn School, BASF agronomist Ken Currah reviews the struggles of the 2017 crop and discusses where, when and what fungicides fit best on corn acres across the province. Currah notes that the earliest corn was planted in late April and growers continued to plant up until about June 10, or whenever there was a opportunity during the cool, wet spring to get planters into the field.
Currah says early-planted corn generally has the highest yield potential and fungicides have consistently shown the best return on these acres. However, he notes that some of the later fields that were planted under better conditions have some of the nicest stands. In these cases, “the foundation is set for yield so why not protect it,” says Currah.
Depending on location and crop development, Currah says growers really have to determine what they need from their fungicide to protect yield.
In this video, Currah reviews application timing and product choices for growers who are focusing on plant health and standability in what could be a late-harvest season; whether there’s a need to protect crops against western bean cutworm; or whether there’s concern for high vomitoxin levels and a need to protect grain quality. Through this lens Currah also offers insight on what fields growers should spray first and also discusses the value of combining late nitrogen application with a fungicide pass.
