UP / Thumb of Michigan | Martin, we've had good weed control results in plots we used to have with rye vs no rye. Those were no-till 30" non gmo soy's. Pre merge chem's were the same across the plots, but there were 2 post sprays required as a rule w/o rye, 1 with. We ran plots for a few years set up this way, and the results were similar each year regardless of weather conditions.
With oilseed radish, we've never seen winter annuals after a good stand.
In corn, I determined a long time ago that if planting a grass into a grass, the established grass ALWAYS wins. For us, that used to be quackgrass back when glyphosate was over 50 bucks. Generally didn't seem to matter if the quack patch was dead at planting or not, corn was always bad there. If the quack was green when the corn got planted, the stand was severely reduced.
I don't know if its alleopathy or autotoxicity we've seen. I know that some folks at Michigan State were working pretty diligently a few years ago at developing covers tailored towards weed control, but I don't know where they got. Some of the work wasn't really aimed at alleopathy per se, one group was trying to determine exactly what habitat Carabid Beetles liked and what it was going to take to encourage a healthy population. | |
