Liberty is a new non-selective herbicide that can be sprayed post-emergence to control grass and broadleaf weeds. The soybean variety must have the gene incorporated in it to allow the use of Liberty. The results on weeds are quicker than Roundup with noticeable symptoms within 48 hours.
The results of the treatments are the average of four replications. Each rep. was 10' x 40'. The weed pressure in the field was moderate. In a harvest check the Asgrow 2704LL beans yielded 56.5 bushels per acre.
