Crop rotation and seed decisions are improved when growers and agronomists have a good handle on the disease situation.

Buying used equipment from a clubroot area can create an unexpected transfer of the disease. We heard this week of a grower from northern Alberta who bought a used combine from a known clubroot area.

Improved moisture in some regions has extended flowering. Some fields have been at “full flower” for what seems like weeks. Highly variable crops may also be at full flower or their “most yellow” — other terms for 50% flower — for longer than typically expected. This does extend the sclerotinia stem rot risk. But that "risk" may still not be…
