1 Assumes crop oil added according to label.
2 Postemergence-directed only.
3 Apply only to Liberty Link hybrids.
4 Apply only to Clearfield (imidazolinone-tolerant or imidazolinone-resistant) hybrids.
5 Apply only to Poast Protected hybrids.
6 Apply only to Roundup Ready hybrids.
7 Multiple flushes of germination; one application of any herbicide will seldom be adequate.
8 With good application timing and a follow-up treatment as needed or a tank mix application, morningglory control can
  be good.
9 Sicklepod control by Lightning can be erratic.  For more consistent control, mix atrazine, Banvel, Clarity, Distinct,
  Marksman, or 2,4-D with Lightning.
Key:
E = excellent, 90% or better control
G =good, 80 to 90% control
F = fair, 50 to 80% control
P = poor, 25 to 50% control
N = none, less than 25% control
-- = insufficient data to rate
