Some fields have already established good stands of wheat this fall. However, there are also some pretty well established fields of volunteer wheat (see pic provided courtesy of Jay Wisby). There have been reports of armyworms and grasshoppers causing concern in some wheat fields that are struggling because of lack of moisture, but the recent cold weather should control both armyworm and grasshopper feeding.

Pea aphids (see pic) are and have been returning, or at least increasing in numbers, to many alfalfa fields throughout north central Kansas. These are primarily cool weather aphids and are usually the last ones still feeding in the fall on alfalfa and the 1st ones in the spring. However, with the advent of cool/cold weather this late fall feeding should be negligible. Potato leafhoppers (see pic), for the most part, have emigrated, or at least are not present in easily detectable numbers, so “hopper burn” (see pic) and its consequences, should not be problematic this fall/winter.

Green cloverworm adults (see pic) have been very common in soybean and alfalfa fields the last couple of weeks, and this has caused concern about potential green cloverworm infestations next year. However, green cloverworm adults are, or have been, migrating to the southern US for overwintering. Thus, since they do not overwinter in Kansas, infestations next year will depend on wherever the adults come back to, so predicting future infestations after overwintering adults return from the southern US are not possible.
