Abstract
Fallow Weed Control with Preemergence Tank Mixes of Sharpen, Zidua, Sencor, Banvel, Atrazine, Balance Pro, and Corvus
Highlights
SummaryWith the exception of the tank mix of Sharpen and Sencor, all other tank mixes that provided 100% kochia control 53 days after treatment (DAT) were three-way tank mixes of atrazine herbicide plus, Banvel, and Balance Pro or Zidua
With the advent of glyphosate-resistant kochia, it has become necessary for producers to apply more complex tank mixes of preemergence herbicides in the very early spring to achieve control
Combinations of Balance Pro and Sencor were needed to provide greater than 93% control of Russian thistle 143 days after treatment (DAT)
Summary
With the exception of the tank mix of Sharpen and Sencor, all other tank mixes that provided 100% kochia control 53 days after treatment (DAT) were three-way tank mixes of atrazine herbicide plus, Banvel, and Balance Pro or Zidua. Two tank mixes provided 98% kochia control 143 DAT. These were three-way tank mixes of these chemistries. Combinations of Balance Pro and Sencor were needed to provide greater than 93% control of Russian thistle 143 DAT. No tank mix provided good control of Palmer amaranth 143 DAT. This might provide a foundation for a subsequent postemergence application in a two-pass weed control program
