I will be starting to work ground and possibly plant some of the g.r.o educational plot this weekend. Here is my observations. We have seen very cool and wet conditions. The weeds were growing well early and as a result we were seeing heading out of these weeds. We always want to spray weeks before they get 6" tall as the taller weeds get, the harder they are to kill. Once they seed out, they are even harder to kill. Sure you might stunt them but your setting yourself up for roundup weed resistance.
We will have various varieties of alfalfa to compare. We will have alsike clover, white dutch clover, ladino clover, medium red clover, 3 annual clovers, oats, triticale, barley and wheat in the plot. We will be challenges this year by mother nature but this tells us more versus when everything is perfect.
