COMMON SCAB PROJECT BREAKDOWNGoyer says theyve looked at how growing certain crops before potatoes can help hold soil moisture in to reduce common Research teamscab incidence. However, theyve had trouble establishing theo Claudia Goyer with AAFC in Fredericton, N.B. nurse crops.

They tried the biopesticide Serenade Soil in Frederictono Manitobaand saw good results for several years. In Manitoba, it reducedo New Brunswickcommon scab severity by 40 per cent compared to an untreatedo Prince Edward Islandcontrol. The best results were seen with an auxin product, 2,4-D, which is basically an herbicide Goyer says. Used in miniscule amounts applied as a fine mist in Manitoba, it reduced common scab severity and produced 69 per cent marketable tubers compared to less than five per cent in the untreated control.Were now evaluating if we need to tweak how much 2,4-D to put in or maybe we need to apply it at a different time dependingFor more stories on research work being done by the Canadian on the cultivars, Goyer explains.
