[Dr. Bob Scott, Extension Weed Scientist standing in a soybean field] Liberty Link soybeans are a new technology that are available from Bayer Crop Science Company. [Sign - Liberty Link Ignite Herbicide Tolerant - Bayer] The thing that make Liberty Link soybeans unique is that they were specifically engineered to tolerate the herbicide Ignite. Ignite is a non-residual broad spectrum herbicide that controls a wide range of weeds commonly found in soybeans. [Pictures of a soybean field with weeds]
One of the most useful uses of this technology is to control glyphosate-resistant pigweed [Dr. Scott] such as this field that that we’re are standing in right here. Residual herbicides look very good with the Liberty Link technology, unlike Round-Up Ready or glyphosate tolerant soybeans where this technology is pretty much been used as a stand-alone. [Picture of a soybean field] Here in this field we’ve used Authority MTZ as well as Valor [Slide showing labels of Authority MTZ, Valor Herbicide and Ignite (for all Liberty Link crops)] in order to provide residual control and then came back with the herbicide Ignite. Right now we’re seeing excellent control with pigweed in this field.
[Dr. Scott] The optimum timing for Ignite on pigweed is when they are very small. [Slide showing picture of a pigweed 2-4 leaf and 1-2 inches tall] You want the pigweed to be somewhere in the two to four leaf stage approximately one to two inches tall. [Picture of a pigweed] If we let the pigweeds get too big we will miss them with Ignite over the top. [Dr. Scott] And again Ignite does not have any residual to the product so you need to add some residual to it. We recommend Ignite Dual if no Dual was used pre-plant it’s a good idea to follow up with an Ignite Dual early post especially in a pigweed infested field.
