We all know that planting a soybean crop is half the battle in getting good yields, however as soon as it’s rising and the potential is there, how can growers shield soybean yield potential?
On this Soybean College episode, Ken Currah, agronomist at BASF, joins Bernard Tobin within the area at Oxford County, Ont., to speak white mould, staging, and fungicide technique.
The circumstances for illness improvement are current within the area that Currah and Tobin are in: it has a historical past of fertility; it has topography and the hollows are vulnerable to white mould, and the cover is dense resulting from slim row spacing.
“This is a field that might be a candidate for some white mould management as well as just managing for yield with soybean fungicide selection,” says Currah. (Story continues beneath video)
Even with drier environmental circumstances, with any moisture in a dense cover, the temperature is about eight to 10 levels cooler than the ambient air temperature, says Currah, and relying on the time of spore launch, the cover is primed for illness improvement — white mould particularly.
Trying on the crop’s stage, across the R1 stage, it’s time to consider managing the crop for white mould, plant well being and yield administration, or each, says Currah.
For strictly a white mould program, the place the sphere has a historical past of the illness, and fertility and the topography all favour improvement, and the range is prone, preventative administration means making use of a product between R1 and R2, when the flower on these decrease nodes is beginning to decay.
A second product will be utilized between R2 and R2.5, when there are flowers on both of the highest two nodes, or the primary flat pods are growing on the decrease nodes, particularly for these longer-season soybeans that want additional safety.
As for value, and return on funding, a single-pass program is actually coated by the bushels gained, says Currah. “Growers that manage white mould know that it’s a pretty devastating disease, and it is a disease of high yields.”
