Fall Armyworm Information

Fall armyworms have arrived and are marching strong.

Multiple generations of fall armyworms occur each year. The damaging life stage, larvae, live for about two weeks but this can change based on temperature. Small larvae do not each much for the first ten days of their life; the larger life stage causes almost all of the damage during the last couple of days before pupation. Smaller larvae are easier to control than larger ones.

Fall armyworms are notorious for having a broad host range, and you may find populations in home lawns, turf, field crops, and pastures. Infestations are especially common in well-managed bermudagrass. Two distinct features identify fall armyworms. The head has light markings that form an upside-down “Y” (Figure 1) while the opposite end has four black dots that form a square (Figure 2).

Scouting is the best way to determine if and how many fall armyworms you have. Grasses can be inspected by getting on your knees and looking at the top of the grass blades during cooler parts of the day and down near the soil surface during the hotter parts of the day. A soap flush in turf may also be used to detect infestations. For row crops and forages, a sweep net is an easy method to sample for armyworms.

IR-4 Survey for Specialty Crop Growers

Attention Specialty Crop Growers!

IR-4 (https://www.ir4project.org/) is conducting their biannual Specialty Crop Growers & Extension survey to assess what disease, pest, and weed problems growers have a difficult time managing because they do not have sufficient management tools.

If you aren’t familiar with IR-4, we have included a link to their website above to learn more.

The deadline to complete the survey has been extended to September 1, 2021.

If you are a specialty crop grower or an Extension Educator working with growers, please take the time to complete the survey to provide your insight and experiences. You can find the link at: https://www.ir4project.org/ehc/ehc-registration-support-research/env-hort-grower-needs-2/

Beef Cattle News

Six new articles have been posted in this week’s issue number 1254 of the Ohio BEEF Cattle letter: http://u.osu.edu/beef/

Sometimes we end up with some ‘fall calvers’ simply because they were late to calve one of the years prior. However, maybe there’s merit in actually planning to have a fall calving herd. That’s exactly what Garth Ruff explores this week.


Articles this week include:

  • Fall Calving, Is It Profitable?
  • Using Nutrient Removal Rates to Improve Forage Productivity
  • Four Never Fail Rules of Grazing
  • Incorporating stockpiled fescue into the winter-feeding program
