ruttinbuc Posted August 18, 2007 Report Share Posted August 18, 2007 Sprayed my strips with roundup the other day and when returning last evening I found very little evidence of the result I expected. Some of the grass and leaves that the mowing didn't get were turning. Most looks like it was never touched. Was wondering if I should just turn it over and try to kill it after that.

Ravin R10 man Posted August 18, 2007 Report Share Posted August 18, 2007 It will take at least one week to 10 days before you see full die off..I would plow too after taht. Quote Link to comment Share on other sites More sharing options...
wtnhunt Posted August 18, 2007 Report Share Posted August 18, 2007 What kind of rate? Used 41 percent glyphosate here at about 1.75 ozs per gallon of water. Sprayed about a week ago, some is turning yellow, some has not turned yet but it will. As hot and dry as it is, seems like it should all be brown already, but not using the fast acting stuff it takes a little more time. Would be a good idea though after you cut it up to go on and spray again about a week later, especially if you see any new growth. Quote Link to comment Share on other sites More sharing options...
ruttinbuc Posted August 18, 2007 Author Report Share Posted August 18, 2007 I used the Weed and Grass Killer Ready-to-use Plus. Says that weeds yellow and wilt within one hour and complete die off in 1 to 2 weeks. Thinking maybe I should have parted with a few more dollars to do it right. We had a heavy rain yesterday. Was wondering what effect that may have. Quote Link to comment Share on other sites More sharing options...

Generic glysophate recommends 3 hours of no rain I believe. Quote Link to comment Share on other sites More sharing options...
ruttinbuc Posted August 18, 2007 Author Report Share Posted August 18, 2007 Says it is rain ready in 10 minutes. Crap, it is only 2.0% glysophate and 2.0% pelargonic acid. 96% other stuff. Ain't no wonder! Or isn't any wonder...sorry teach! Quote Link to comment Share on other sites More sharing options...

For premixed, that is probably about right. Dont know about rain ready in 10 minutes with glyphosate though. Quote Link to comment Share on other sites More sharing options...
Guest luckyman4 Posted August 20, 2007 Report Share Posted August 20, 2007 Sprayed my strips with roundup the other day and when returning last evening I found very little evidence of the result I expected. Some of the grass and leaves that the mowing didn't get were turning. Most looks like it was never touched. Was wondering if I should just turn it over and try to kill it after that. Glyphosate works by getting absorbed into the leaves, if you mowed first, there was less leaf area to be absorbed into. It sounds like the stuff worked fine on the plants that weren't mowed. Hot, dry weather also helps glyphosate because it works by dehydrating the plant, if I remember correctly. Rain will wash it off, but most of the new stuff claims to be absorbed quickly, so that probably isn't as big an issue as the extra moisture helping the plant live an extra day or two. You can turn the soil over and try to kill after that, but you have to let the new plants grow enough that the herbicide can be absorbed. Doing this will help decrease the number of weed seeds in the soil, and hopefully the number of weeds in your plot. Just remember that most glyphosate products recomend a minimum of 10 days between sparying and planting, so you are putting off planting time with each spraying.

ruttinbuc Posted August 20, 2007 Author Report Share Posted August 20, 2007 Thanks for the info luckyman4. Time is the issue. We are having a day of rain here and expecting more. I just may scrap the plan for this year and put in something like secret spot. I was looking for some late fall/winter forage for the late gun seasons and winter bow.

matq2gs Posted September 4, 2007 Report Share Posted September 4, 2007 The biggest problem some people make is that they don't put enough water on per acre. And also the smaller the tips in your sprayer the better your coverage on the plant will be. Also so weeds shut down when under drought stress and it will take longer to kill them.Some chemicals tell you not to spray when weeds are under stress. Check your lable and see about how many gallons per acre is recommended. Also if you buy roundup from a farm supply store it will be different than say a Lowes or home Depot. The commerical stuff will have a sticker agent helping it stick to the plant better.Good luck. Quote Link to comment Share on other sites More sharing options...
