I have just received my first report of Fall Armyworms this year. Last year we experienced a couple areas that had some damage but wasn’t very wide spread. So to keep us prepared the link below goes to information about armyworm control that I put together last year.
Keep a look out for fall armyworms. A couple of reports have been around the Derby, KS area and have already caused some damage to tall fescue turf. These armyworms were already 1 to 1.5″ long.

Just yesterday I was out on an extension visit and came across more fall armyworm (FAW) damage. Pulled the turf back and found some small FAW. To get more information on what FAW look like, check out one of the latest blog posts about identification, cultural control, and a little bit about chemical controls for home owners.
With the amounts of sightings increasing I thought I would throw a list of chemical controls for turfgrass professionals for FAW.
FAW and all caterpillar pests are best controlled with insecticides when they are still small. When the caterpillars grow you will have to use a higher rate to achieve control.
Tempo SC Ultra (landscape turf only) – RUP, Tempo 20 WP (Golf course only)
deltamethrin
DeltaGuard GC 5SC
RUP
halofenozide
Mach 2 2SC
lambda-cyhalothrin
Scimitar CS (landscape turf only
RUP
spinosad
Conserve 1SC
trichlorfon
Dylox 80 T&O
Always remember to READ THE LABEL for the correct rate, turfgrass tolerance, and specific instructions before application!!!
