In a demonstration conducted by Crop Production Services (CPS) in Galesburg, Illinois, Extract PBA was sprayed in fall 2017 on a corn field post-harvest. In spring of 2018, stalks were pulled and split to examine the differences in residue breakdown between treated and untreated parts of the field. As seen in the photo, the Extract-treated stalks were in a more advanced stage of decomposition than untreated stalks by early spring.
Extract PBA was sprayed on Nov. 29, 2017. This photo shows corn stalks from treated and untreated parts of the field that were pulled and split on March 23, 2018.
