2 4 d and tempature

[Bigfoot]

I finally got a "little rain". It seems to have only helped the weeds, and not the grass. Infact I am pretty sure most of my fescue is dead. I sprayed 2 4 d to control the weeds. One tank full any way to see what it would do in warm weather. It doesn't seem to have done much of anything. I've always heard that 2 4 d doesn't work well in warm weather. If it was the warm weather what can I spray for broad leafs. I don't want to use graze on. I didn't bush hog, and let the fescue go to seed. I think I might be relying on the seed bank to have grass next year. Any suggestions.

Give the 2,4-d a chance, but if the weeds aren;t really actively growing well nothing is going to affect it. Grazon is 2,4-d and picloram, the picloram is the residual. Fescue is pretty much dormant when the temp is in the high 80s so don;t expect much from it till this fall but only if you continue to get rain.

IF it is cooler in the latter part of the day, you may have better luck with it. In extreme temps--that is the heat of the hottest part of the day, lots of plants including weeds furl their leaves and foilage.
I've seen goatweed and other weeds curl their leaves in the mid afternoon and open them later when the sun got lower.

Here in Texas I sprayed 2, 4d on a pasture full of weeds that was way overgrown in spring and didn't see much results. I bushhogged the weeds then sprayed 2,4d after they started popping up again and that has done the job. Pasture looks better than it has in years. I think the key is not letting the weeds get too high or nothing will kill them.

What was your application rate of 2,4-d? Did you use a surfactant?

At this time of the year, if your fescue has finished seeding out, I'd recommend Chaparral at 3.3 oz. per acre. Next spring, when whatever weeds are left are 3 or 4 inches tall, go over it with 2,4-d at 2 qts. per acre w/fertilizer.

 

[Bigfoot]

About 3 pints to the acre. I squirted a little dish soap in it. Not really what you would call a surfactant. I usually put this same application on twice in the spring. The weeds I'm spraying just came up. Most are really small. I've seen it not kill the mature weeds, never the small stuff. I'm sure if I mowed it close, and sprayed again they would die, but grass is at a premium now for me. I don't want to mow any blade down. Is chaparral expensive?

I don;t recall off hand what temp it is, but at some point 2,4-d has a tendency to volatize more and spread to adjacent areas from where it's applied. They warn against using it in conditions of high temps (not specified what high is) and low humidity (not speciefied what low humidity is).
I typically don;t use it over 85 degrees.

I did the same thing==sprayed early with poor results. Then sprayed a different pasture about a month later and had great results--using exactly the same mix and spray rate I had earlier. I figured the weeds just were there, but not yet actively growing so the Remedy didn't do it's best on what I sprayed in early spring.
Chapparal isn't for use on Bahia so I don't use it, but I found this ad in a quick search.

It's a dry granual product. You can probably beat that price but

Ouch!

It is not so much the price of the product as the price per acre.
I have been using Cimarron Plus at 90 something bucks for 10 oz. But it will do up to 30 acres.
You cannot use this on Bahia either unless you want to get rid of it.

long as grass is growing the temp don't matter. If its a drought, don't waste your spray. If it's too cold for grass growth dont' waste spray

Yep--"actively growing non stressed" is the key phrase on any specimen label instructions.

I've had some luck applying it in the heat down here but in was either mid morning or late evening using a surfactant and the application rate was about 1 oz per gallon of water. The heat can actually work to your benefit if you can apply when the temp hasn't risen to the high point yet.
