Uneven crops and swath timing
The swath timing decision becomes more difficult in crops with plants at multiple stages of growth. Here are some tips to help with the swath decision on these fields….
Insect update: Check to be sure
Diamondback moth larvae and grasshoppers have been reported, but so far nothing of widespread significance. The photo shows what grasshoppers can do to a canola plant, but their damage is usually isolated to small patches. Bertha armyworm adult traps are coming down with very little in the way of hotspots.
Long flowering and sclerotinia risk
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 high enough to warrant a fungicide spray — given the risk was so low before and that late applications tend to have a reduced benefit for yield.

Why do reseeded crops look better this year?
Various studies and crop insurance data show that canola seeded in early May tends to yield more than canola seeded in late May. Agronomy decisions are based on these trend results. But with the unpredictability of crop production, situations often come along that buck the trend. This year may be one of those years. Why?

When spraying, stick to the pre-harvest interval unique to each product. When prepping bins, follow canola storage recommendations….
