Spraying RR beans when “dewey”…

Assume a guy has zero time during the day (or wind conditions aren’t right, or whatever and he can’t spray during “optimal” conditions…)

How much less effective would spraying RR beans/corn be if spraying early in the morning on very wet, dew covered crops/weeds? (Not rain conditions, just dew conditions)

Will it still work, or is it a waste of time/$$?

Wondering if anyone has had experience with this.

It’ll work fine. I spray test plots all the time in the am before the wind picks up. If it didn’t work – the coop guys would never get caught up.

I sprayed mine in the am with heavy dew, after I finished it started to rain…1 week later all the weeds and grasses were dead.

x3 on it works

What are you guys using for application rates,I got a new sprayer and am having a bear of a time dialing it in

I have a small 15 gallon sprayer…used 3 oz of roundup per gallon and worked great.

Right around 3 oz (of 41% Glyphosate) per gallon gets the job done for spraying RR ready stuff. Thats about a 2% solution. A 4% solution will make the ground between your rows looking like the moon, haha. Depending on speed and application rate from your sprayer, id say that if your getting about 2 pints of Gly applied per 1/2 acre your going to have good results. I guess I don’t worry about over application too much as I would rather hit it hard once and be done than have to come back. So basically if you put 32 oz in just over 10 gallons, put it all on a half acre you’ll be sitting pretty. Hope that helps

Just be careful by “hitting it hard”. Label rate is 22 oz RoundUp per acre for RR alfalfa – similar for beans. You’re putting a 3x rate on and this may burn/stunt the beans. More isn’t always better. At labeled rates all weeds will be burned down within a week if you have any precip. In dry conditions may take a little longer.

Thanks guys. I sprayed the end of last week, and already am seeing more beans and less weeds. Weeds are dying off nicely.

Thanks!

I appreciate the heads up. I am spraying Cornerstone Plus (41%). I used to use less, and fully understand that a little goes a long way with Glyphosate. I initially began to increase my application rate when I began digging under some clover and alfalfa plots and planting corn, and in one instance beans. I had a heck of a time getting the volunteer clover and alfalfa under control. Thats when I went back to the label to see what the upper limit of the application recommendation was.

Label states- “Soybeans with the Roundup Ready Gene — In general, an initial application of 1 quart per acre on 2 to 8 inch tall weeds is recommended. Weeds will generally be 2 to 8 inches tall, 2 to 5 weeks after planting. If the initial application is delayed and weeds are larger, apply a higher rate of this product. This product may be used up to 2 quarts per acre in any single in-crop application for control of annual weeds and where heavy weed densities exist.”

Upped my application rate and solved my problem. Furthermore, it cured my issue with field edges getting filled in by creeping weeds (specifically large cocklebur plants) from the woods, as well as those years where I just don’t have time to get out and spray when all the weeds are young and short.

I couldn’t tell you what any of Monsanto’s actual Roundup trademark brand labels say, I just know they are different concentrations and formulations. I was just going under the auspice that 41% Glyphosate is 41%, and stated what works for me based off the labeled information I used.
