Armyworms...

[Doelman]

If this terrible weather with constant rain in the south wasn't enough, it appears my tomatoes have come down with a serious case of southern armyworms. I've never had to deal with these buggers before, what do you guys suggest? I've been killing every one I can find, but every day I find a new horde munching away, will Neem oil help?

Neem will not help. Use a Bt (Bacillus thuringensis) product. Any nursery will have it under a bunch of different trade names. I will kill them all within a day and they will stop feeding within 4 hours. It is a safe organic product that kills only caterpillars
