Monitor Canola Fields for False Chinch Bug Activity

While scouting canola this week, I came across a field that had plants along the edge that looked like they were suffering from drought stress, but given the recent rain I doubted that to be the case. Closer inspection of the stressed plants indicated that they were covered in false chinch bugs. Although false chinch bugs are not normally an issue in canola, very large populations do have the potential to reduce yield.

Flea Beetles Still Feeding in Canola

Flea beetle adults are still causing trouble in canola this week. In one field we scouted, populations were very large and were causing large amounts of defoliation on emerging late-planted canola. It is important to continue monitoring fields to ensure that populations have been successfully managed and defoliation isn’t occurring.

Flea Beetles Defoliating Canola in South Dakota

This year flea beetle emergence is behind schedule, but so is a lot of the canola emergence. We are observing very large flea beetle populations on late-planted canola that is just emerging. As a result, much of this canola is being heavily defoliated and will likely require foliar insecticide management.
