When to throw down the Crabgrass preventer

[deerwhacker444]

The internet says Crabgrass germinates when the soil average hits 55-65 degrees.
Current Mesonet measurements have the 2" soil average at 50-51 where I'm at, I suspect it's warmer at seed depth. With a Sunny 4 days forecast ahead, followed by rain on Monday, then some more sunny days, is it time to throw down the preventer or is it still too early?

The winter weeds/grass are probably going to get Round-up'd next week before they really take off to make room for the bermuda grass.

Thoughts.?

You're about right. I just bought some stuff at attwoods to prevent crabgrass and sand burrs. Can't remember the name right off hand. Liquid stuff to put in the 3 point sprayer. I'm thinking this weekend is going to be prime time as there is a 90% chance of rain Monday like you said, and this stuff needs at least 1/2" of rain to activate and get into the soil. Have to do it again in July.

Barricade is best pre emergent you can buy. Prodiamine is the chemical.

Its Surflan. It already has the dye in it to show where you've sprayed.
It was on 50% off at Attwoods. Don't know if it is now.
I buy it by the 2 1/2 gallon jugs for the farm.

I spray with a 15 gal. ATV sprayer. Wonder if I could mix that and Glyphosate together in the same tank, kill 2 birds with 1 stone.?

Don't know off hand without looking at the websites. Some chemicals you don't want to mix, others are just fine and do double duty.
