Seeding Rate:
Mono (lbs./acre): 15-20
Broadcast (lbs/acre): 20-25
Forage (lbs./acre): 25-30
Seeding Info:
Seeding Depth (in./with drill): 1/2-3/4
Aerial Application Rate: NR
Considerations:
Sorghum x Sudangrass presents the opportunity for prussic acid toxicity, especially after fall frosts. Nitrogen applications are highly recommended if the goal is to maximize forage production; however, those same fertility supplements can pose an increased threat of elevated nitrates in sorghum x sudangrass after plants are stressed.
Termination:
A frost will terminate sorghum x sudangrass, millet, sunflowers, cowpeas, and sunn hemp. Brassica species will terminate with multiple nights in the teens. If any brassicas overwinter, glyphosate and 2,4-D provide adequate control.
