Some herbicides aren’t very effective at controlling a weed like horsetail, but when you combine two poor-performing products, they can deliver a surprising level of control.

This is supposed to maximize light interception by the crops, which in turn maximizes photosynthesis. In contrast, east-west rows have more shading and this negatively impacts yields. Is the same true… Read More
