| Abstract/Contents: | "Field experiments were conducted in GA on large crabgrass and TN on smooth crabgrass. Treatments in GA consisted of EH1579 (penoxsulam + pyrimisulfan inert carrier) [90 g ai ha-1, 180 g ai ha-1, and 90 g ai ha-1 followed by (fb) 90 g ai ha-1], EH1580 (penoxsulam + pyrimisulfan - fertility carrier) (90 g ai ha-1, 180 g ai ha-1, and 90 fb 90 g ai ha-1), and indaziflam at 32.7 g ai ha-1 (industry standard). Treatments were similar in TN, but industry standards consisted of prodiamine at 840 g ai ha-1 and dithiopyr at 560 g ai ha-1. EH1579 at 90 g ai ha-1 resulted in 81% large crabgrass control 85 DAIT, while EH1579 at 180 g ai ha-1lR or 90 fb 90 g ai ha-1 resulted in 73 to 80% smooth crabgrass control. EH1580 at 180 g ai ha-1 or 90 fb 90 g ai ha-1 resulted in 58 to 62% large crabgrass control and 89 to 93% smooth crabgrass control. EH1580 at 90 g ai ha-1 only resulted in = 63% crabgrass spp. control 85 DAIT. Crabgrass spp. control was = 56% 112 DAIT in response to EH1579, regardless of rate, application frequency, or trial location. EH1580 at 180 g ai ha-1 or 90 fb 90 g ai ha-1 resulted in 68 to 69% large crabgrass control in GA, while a single application of EH1580 at 90 g ai ha-1 only resulted in 41% control 112 DAIT. Smooth crabgrass control was 84% 112 DAIT in TN in response to EH1580 at 180 g ai ha-1, while control dropped to 63 and 43% in response to EH1580 at 90 fb 90 g ai ha-1 and 90 g ai ha-1, respectively. Crabgrass spp. control was 96%, 91%, and 69% 112 DAIT in response to prodiamine, dithiopyr, and indaziflam, respectively." |
