Application intervals for post-emergence dicamba applications in Xtend crops expanded

Due to weather-related difficulties this year with planting and timely herbicide applications, the Kansas Department of Agriculture (KDA) has approved a special local needs (SLN/24(c)) label to allow for expanded application intervals of Engenia, Xtendimax and FeXapan on Xtend soybeans and cotton.  Application to Xtend cotton has been expanded from 60 days after planting to 90 days after planting. Application to Xtend soybeans has been expanded from 45 days after planting to 60 days after planting or the R1 stage of soybean growth, whichever comes first.  Below is the announcement from KDA regarding the SLN labels.

A special local needs (SLN/24(c)) for use on dicamba-tolerant cotton and soybeans is now available for growers for the following products - Engenia, Xtendimax with Vapor Grip Technology and DuPont FeXapan Plus Vapor Grip Technology. The SLN labels allow for application up to 90 days after planting in DT cotton and 60days or R1 growth stage, whichever comes first, in DT soybeans. All other restrictions of the Section 3 label apply. The SLN labels are available on the KDA website (https://agriculture.ks.gov/divisions-programs/pesticide-fertilizer/pesticide-product).
