I am trying to cut down on some of my roto tilling. I am trying to come up with a chemical plan for the weeds in my sweet corn. Years ago I used to just buy 2 4 d and Atrazine and problems were solved. Well in Indiana, now you have to be certified to apply chemicals on the ground. Test cost 100 dollars a try, 25 a year to keep it up. Well that seems like a lot of trouble and money for a couple acres of sweet corn, that I'm going to give away. Has anyone got any suggestions??? Any easy ways to keep the weeds down in corn. My best attempt without chemicals was when I first got a little 4 cycle Honda tiller. It would get right next to the plants/rows without any harm, and would go as fast as I could walk. Made quick work of little weeds. Well the bottom end went out of that little tiller 2 years ago. I bought an Earthquake little 2 cycle tiller from Lowe's and it is a piece of junk. Won't start 3/4s of the time, and then it does not run as good as that Honda. I'm going to attempt to fix that Honda this spring, have it on a piece of cardboard in the house now in fact. I hate to have to buy a new Honda again, as they are 300 or so in price. A lot of money for 2 years use, then out goes the bottom end. I don't think they thought people would use them on 2 - 4 acre garden plots. But when they are running, they are the slickest thing out. 22 pounds of weed kill-en power. lol So lets get a discussion going on weed control.
