First time with army worms

[JDGreen]

2 nights ago noticed the odd stripped pod, but couldnt find what was eating them. Tonight 30-50% of plants have the top 3-6 pods stripped. Couldn't find the bastards but waded in 75 feet or so and there they were. Never seen them before and have been growing canola since 1992. Ugly brownie black worms bout 1.5 inches long slithering and chewing on pods. Saw maybe 15-20 of them within a 8 foot radius of where i was standing. No planes available for tomorrow so will go in with the tridekon crop dividers with Lorsban?? What rate?? Do they only come up to feed in the evening?? So many questions.

Spray, Just remember to go opposite of
what you swath if its thick!

[seabass]

Evening is the best or spray all night. 25 ac a jug will kill the buggers. Don't wait any longer. Big ones like that can eat alot. In my experience spraying Lorsban during the day will still kill them just don't go out there for 3 days. Good luck and wear a respirator when filling.

[SASKFARMER3]

We have one guy fill and wear the suit.
Sprayer driver doesnt fill. If their
eating pods and moved up from the leaves
kill the little buggers they will do
damage.
Some who find realize that if you still
have leaves they will eat their before
moving up. so dont spray to soon.

Ok thx guys but now have local agrologist telling me decis or matador works better than lorsban? What u say? Also what water rate would you use in a thick crop?

[groundspeed]

Had lots of experience with worms. All the chemicals work ok if their up on the plants, however if your spraying later in the morning use a chemical that has residule. Lorsban has 2 modes of action.

[JDGreen]

Using lorsban. Is the rate of 400ml necessary??
They are only 5-6 in a square meter but can they
ever chew up pods in a hurry.

[SASKFARMER3]

25 acres per 10 liter jug.
2 mode action kills them dead. Not contact.

Gracias senor SF3....

Preharvest interval for Lorsban - 21 days, Decis 7 days. Harvest is considered swathing not combining.

I usually use matador, it's cheaper and
less likely to kill you.
