Army Worms

[Kthompson]

Good ole army worms, we have an early breakout of them here in NE TX.
I normally cut the fields to force them to leave but they caught me by surprise this time and wiped out a couple of fields.

What do you recommend to spray on them that would kill but not have a grazing restriction?

Thank you!
Kevin

If they still sell it I've always used sevinXLR, I'm about 20 minutes from Winnsboro

Is there no way to keep cattle off the affected fields? If you can remove cattle, I've used bifenthrin successfully but it does have 30 day restriction.

Here is what is labeled in Texas:
*Mustang Maxx (9.6% zeta-cypermethrin). The first pyrethroid insecticide labeled on pastures and hay fields. Applications may be made up to 0 days for forage and hay, 7 days for straw and seed screenings. Labeled for a large number of insect pests, including armyworms, grasshoppers.

*Lambda Cy Products (Lambda Cyhalothrin) - Pasture and rangeland grass, grass grown for hay and silage and grass grown for seed. Pasture and rangeland grass may be used for grazing or cut for forage 0 days after application. Do not cut grass to be dried and harvested for hay until 7 days after the last application. This product tends to be the most economical.

*Dimilin 2L (Diflubenzuron) Wait one day until harvest. Label does not list a restriction on grazing and 1 day for hay. To be effective, Dimilin must be applied before larvae reach ½ inch. Will not control larger larvae. Provides residual control for up to 2-3 weeks, as long as forage is not removed from field. Dimilin acts as an insect growth regulator.

Intrepid 2F (Methoxyfenozide) Do not harvest hay within 7 days of application. There is no pre-harvest interval for grazing. Begin applications when first signs of feeding damage appear. Use higher rates for heavier infestations. Intrepid is an insect growth regulator.

Baythroid XL (Beta-Cyfluthrin) Pasture, rangeland, grass grown for hay and seed. Labeled for control of small (1st and 2nd instar) fall army worms. Zero days to grazing or harvesting hay.

Sevin 4F, Sevin XLR, Sevin 80S & Generics (Carbaryl) When applied to pastures, there is a 14 day waiting period before grazing or harvesting for hay.

Malathion 57% and Malathion ULV. Zero days to harvest or grazing.

Prevathon (Chlorantraniliprole) Prevathon has a 0 day waiting period for harvest or grazing and is not a restricted use insecticide.

Vantacor- Same as Prevathon that is highly concentrated with lower use rates per acre.

*Besiege (Chlorantraniliprole +Lambda cyhalothrin) no grazing restrictions. 7 day pre-harvest restrictions. Tracer (Spinosad) Do not allow cattle to graze until spray has dried. Do not harvest hay or fodder for 3 days after treatment. There is no pre-harvest interval for forage. Treat when eggs hatch or when larvae are small. Use higher rates for larger larvae.

Prev-Am (Sodium Tetraborohydrate Decahydrate) no grazing or haying restrictions. It is listed as an insecticide, miticide, and Fungicide on label.

*Denotes that the pesticide is restricted use and a Texas Department of Agriculture (TDA) applicator's license to purchase product is needed.

To expand on my short Thank you from yesterday, I really appreciate the info.
This is a great example of why I love this forum , people always willing to help others.

Well the army worms have hit here now. Since they have wiped out a couple fields no need in spraying. I think they just last a couple weeks don't they?

 

[Kthompson]

Sorry for the slow reply

.
I wound up having to spray twice over 30 days to beat them down, with no rain they seem to be tougher

There is that downside, but there is an upside...... you will be ready for them when they come and will be very vigilant!

Propane and a weed burner...

And make sure it doesn't spread.

@Travlr, aside from the fact that we are trying to save the grass for the livestock to eat, your idea brought back memories of a news article I read 2-3 years ago about an individual that was afraid of spiders and got one in his house. He proceeded to get a lighter and an aerosol can of something flammable, I don't remember what it was. He then proceeded to attempt to flambe the spider. I don't know if he was successful in torching the creature, but he didn't have to worry about the spider in his house any more because he no longer has a house.

I do like your enthusiasm in going after the army worm though.
