RR soybeans are a good deal. Hard to get all the weeds in a soybean field, & the conventional chemicals used to be very expensive. Never understood RR corn tho. There are some most excellent corn chemicals & tank mixes that are pretty cheap, and give season-long control to both broadleaves & grasses. Roundup you will probably have to spray a couple of times, as it does nothing to control new sprouts. Some conventional corn sprays give good results if sprayed before the 5th leaf appears, and some can be applied up to ~2 feet tall. Then you can get drop nozzles and spray tassled corn if you want. 24D is cheap to control broadleaves, Banvil/Clarity (similar product, different name) is very good on broadleaves, hard on taller corn. There are many pre-mixed products that also have a grass control in them. Post-spraying has become very popular, you will find more chemicals to spray after planting than before these days. Liberty Link is an alternative to RR, it was a naturally occuring corn that doesn't die to that particular chemical, while most weeds do. On a personal note I do not like signing away my soul to the company licencing the RR technology. If you read all that fine print, you find you have already admited to being guilty, & what your fines will be, at the whim of the company. Really the same thing on all the software we buy now a days - companies have found they can get around consumer protection laws & control the customer with licencing agreements instead of outright sales. My rant for the day, don't mean to turn this political, you have a good question & want facts, not rants. :) --->Paul
