Army worms

[cowboy43]

what insecticide do you use to spray army worms, what does it cost an acre for the insecticide ?

Mustang if you have applicator licence.
If not seven,

Thanks that chart answers all questions,

I use Lambda- Cy. I think it is listed as Karate on the chart. No grazing restrictions. Note those prices are out of date. Shop around.

I use Intrepid. Best residual of all insecticides labeled for armyworms. Baythroid mixed w/ Dimlin is cheaper but doesn't have as good of a residual. Intrepid costs around $10/AC. Baythroid/Dimlin costs around $6/AC.

Are you seeing them already?

 

[cowboy43]

I haven't seen any, but yesterday I saw a lot Of moths flying , I am not sure sure what they were, I need to research their life cycle and what the moths look like.

5 centimeters is about 2"

We've been seeing a tremendous amount of moths.. more than I can ever remember seeing
Husband says it should be about 2 to three weeks to spray time.

I'm surprised y'all got them in Texas.
I sprayed carbaryl @ 12.50 acre, 14 day grazing restriction.
Maybe my grass will grow in 2 weeks but doubt it with no rain.

 

[cowboy43]

How long after the moths appearance do you spray?

Add 2oz of Dimlin per acre it'll last till you cut.

I'm not sure what that timeframe is because I didn't notice the moths and was walking the pastures almost daily.
I got a bulletin from our county ag agent about locals having worm infestation. A friend called 2 days earlier to warn me but he's 60-70 miles away.
This is my first battle with them.
I've had a couple very experienced guys tell me that a good hard rain with drown them off....I waited a couple days but no rain from that hurricane so I sprayed.

A good hard rain supposedly only kills the juveniles. My advice is if you have army worms spray.

Thanks True Grit but I don't cut any hay, just graze mine.
Wishing I'd got a less grazing restriction formula but not much grass anyway.
I'm feeding hay and feed again.
6 of my 8 heifers calved in a week so their in milk now.

I'll need to remember that too!

A good cold rain or a night with a few hours below 50 degrees seems to stop them.
I try to wait until I start seeing the square Windows in the grass blades to spray. But you have to be ready . If something breaks down and you wait a couple days, they can graze you completely out.

I know almost nothing about them. In my life, I've only had experience with them 1 year. Summer of 2014 I believe. At first, i had no idea what was going on. By the time I figured it out, it was too late. I don't know if you guys warm season grasses bounce back from an attack or not. My fescue did not. I just assumed it would come back the next year. It seems to survive everything else nature throws at it. Ive put it off long enough, I'm going to have to rent a no till drill, and reseed every where they've been.

You would be better off easing through your field at dusk or dark with your lights on and this is when its easiest to see the moths. You'll know them.

I've had a lot of experience with them, unfortunately. Check your fields at least every other day. I walk mine. Bend over and spread the grass back. Look closely. Best to check right before dark or first thing in the morning. Treatment threshold is 3-4 worms per square foot. Another way to check them is to drag a five gallon bucket across the field with a rope but this won't tell you how many you have. Another way is to drive across the field and look at your tires. They will be greasy. But again this only tells you that you have worms. I prefer to check by walking and looking. Sometimes once you see the cattle egrets it's too late.

The chemical you use depends on your stage of production and on whether you're grazing or haying. Dimlin is very good and very inexpensive but only garauntees a 2 week residual. I've had them in hay when it was only 2 weeks after I cut it. So it depends on the situation. I get the little pests every year and usually more than once. If you have high quality heavy fertilized grass in my area they will find it.

A heavy rain will only kill the small ones. As for temps below 50, I will take fence's word for it bc we never have that here during any part of the fall hay growing season :bang:

They definitely play he'll with heavily fertilized bermuda pastures.
My pastures are mostly klien and bluestems. They don't bother them to much.
It's oats were we fight them the most. I haven't used dimlin , it seems like I recall it doesn't kill the larger worms well. Could be wrong about that. Mustang max will smoke them along with grasshoppers . and it's pretty cheap. It is very toxic to fish so I avoid it in areas that drain into my fish ponds.
We were ready to spray a pretty bad infestation last year in late September. Got a good cold rain and the next morning the fields were full of cowbirds. 1.5 inch worms layed out everywere. Didn't have to spray so at least i don't have to buy the chemicals this year. Its on the shelf in the shop. :cowboy:
I walked thorough my haygrazer a couple of days ago. More moths than I've ever seen BY FAR :shock: there's a train a coming no doubt
