After farmers reported seeing target spot in their cotton in northeast Arkansas and southeast Missouri in 2015, BASF’s John Schultz and Ryan Bane asked several growers if they could set up demonstrations in their fields in 2016.
One of the producers who agreed was Arkansas’ Greg Womack. Schultz and Bane picked out three 10-acre blocks in one of Womack’s fields ndear Lake City, Ark., sprayed two of them with 4 ounces of Priaxor in the second week of bloom; and one again with 4 ounces of Priaxor at the fifth week of bloom. The third block was left untreated.
"The block that received two applications of Priaxor averaged about 100 pounds more lint than the untreated," said Schultz, a BASF technical service representative in Sherwood, Ark. Schultz was interviewed at the field during harvest.
"We've heard that some growers experienced significant yield reductions due to the disease in 2016, so we'll be following up on this and on other fields in 2017. We have a number of questions, including some about height management by target spot and what percentage of the defoliation caused by the disease helped us and how much of it hurst us."
Schultz is scheduled to speak on the trial at the Beltwide Cotton Conferences in Dallas, Texas, Wednesday.
