I had heard if Round-UP is applied 30 minutes before a rain that it will work but never tested it by intent but did unplanned about three weeks ago.

The sprayer had been filled (15 gallon/golf cart rig) and it started coming up a cloud and I was going to be out of town so I did not want the mix to set for a week or two so I sprayed it out and within 30 minutes it came a flood as in a hard down pour over time.

The kill on weeds and briars was good. The burning back of leaves on bushes effect was less it seemed after inspecting the road and fence areas but overall I was impressed with the kill three weeks later since hard rain came within 30 minutes of application.

I did the same thing a few years ago, but you could see where the water ran off the fenceline and into the yard. OOPS.

I will look more in detail tomorrow afternoon but were I sprayed was not critical areas. No sure why but sometimes with the same mix ration I get a much better kill than at other times.

Me too. I have never sprayed when it was going to rain. I knew about the time window between spraying and rain but I have been able to spray with no rain in the forecast. Nice to know the time window is correct and long enough to kill the plants.

Later,
Dan
