Giant ragweed is a giant problem, especially for organic farmers. Not only does giant ragweed decimate any potential yields, it spreads like wildfire and if left untouched, can ruin a farms yields for years.
Let’s take that back. If left untouched, giant ragweed will 100% ruin yields. For obvious reasons, getting a giant ragweed problem under control is critical. The plant is so tall and so tough that it can actually dramatically affect the harvest of your crop. In small grains, or any other crop that finishes early to mid season, harvesting while ragweed is still growing will jam the combine. On the corn and beans side, you’ll have to wait for a frost to kill off the ragweed.
How does giant ragweed spread?
The downfall is, on corn and beans, by that time if you’ve got ragweed in your field, the seeds that the ragweed makes are now viable and get spread all over your field. Eventually, you’ll move to the next field and the seeds that are in your combine travel with you and get spread to the next field. The same thing holds true for every weed that you harvest during the fall. For farmers just transitioning to organic, learning how to control weeds in organic farming is one of the most important things you’ll need to learn.
Giant ragweed is difficult to control because of the speed at which it grows and the height the plant reaches. According to the
