The objective of this study was to compare ImiFlex rates and timings for efficacy crop response in imidazolinone-tolerant grain sorghum. Volunteer corn Johnsongrass control generally best when (imazamox) applied postemergence (POST), except tank mixed with Huskie (bromoxynil/pyrasulfotole). Likewise, Palmer amaranth most consistent POST. Though all herbicides increased yields relative the weedy...

The title compound [systematic name: 3-hy-droxy-2-(4-methyl-sulfonyl-2-nitro-benzo-yl)cyclo-hex-2-enone], C14H13NO7S, is the enol form of a benzoyl-cyclo-hexa-nedione herbicide. As a result of this tautomerization, there is intra-molecular O-H⋯O hydrogen bond enclosing an S(6) ring motif. The cyclo-hexene ring has an envelope conformation, with the central CH2 C atom as the flap. Its mean plane...

Photochemical reactions involving a variety of photosensitizers contribute to the abiotic transformation of pesticides in prairie pothole lakes (PPLs). Despite the fact that triplet excited state dissolved organic matter (DOM) enhances phototransformation of pesticides by acting as a photosensitizer, it may also decrease the overall phototransformation rate through various mechanisms. In this s...
