There are weeds that have producers moving from a glyphosate weed control program to a glufosinate weed control program. Glufosinate is the active ingredient in Liberty® herbicide. This switch has been forced by the spread of glyphosate resistant weeds due to continual and repetitive use of only glyphosate across wide geographies of the United States. Among the most common and yield damaging weed species are Palmer amaranth, waterhemp, marestail, common ragweed and giant ragweed. Cost to control these weeds can exceed $100 per acre. It should be noted that many of these glyphosate resistant weeds are also resistant to ALS herbicides, PPO herbicides among others.
Liberty herbicide is very effective in controlling annual weed species in LibertyLink® cropping systems. Currently it is the only nonselective herbicide that is effective on these hard-to-control grasses and weeds. It is fast acting and results are visual within days of the application. There is no known resistance to Liberty herbicide.
A successful herbicide program utilizing Liberty has to include a comprehensive program of pre-plant options, pre-emergence residual herbicides and Liberty applications to be fully effective, and reduce the risk of developing additional weed resistance and protect the long-term sustainability of the Liberty technology.
Do Not Plant “green”
Utilize Residual herbicides
Post-emergence applications of Liberty
Removing weeds when small prevents competition with the crop being produced, and also prevents the potential of yield losses. The economic rationale for removing all weeds in a herbicide weed control system is the protection against eventual weed resistance.
