- In regions with regular killing frost:
- Dense stands
Apply Milestone™ (5 to 7 fl. oz/A) or Forefront™ (2 to 2.6 pt/A) in the late spring or early summer after all perennial
plants have emerged from winter dormancy and before fruit development. Monitor the treated area beginning in the late summer
for escaped plants and be prepared to spot-spray with Milestone (10 ml per 2.5 gal)1, Forefront (50 ml per 2.5 gal)1,
or Remedy™ (50 ml per 2.5 gal), plus surfactant and color marker, in the fall as needed. Continue to monitor this site for
at least 1 year to determine if additional spot-spraying is sufficient, or if the entire area should receive another broadcast
application of Milestone or Forefront.
- Sparse stands
Spot spray in the spring with Milestone (10 ml per 2.5 gal), Forefront (50 ml per 2.5 gal) or Remedy (50 ml per 2.5 gal),
plus surfactant and color marker, and monitor every 45-60 days to determine if additional spot-spraying is necessary.
- In regions without killing frost:
- Dense stands
Apply Milestone (5 to 7 fl. oz/A) or Forefront (2 to 2.6 pt/A) in the late fall or early winter after plants have fully recovered
from the summer stress, but prior to fruit production. It is possible that mowing TSA plants will be necessary to prevent
significant fruit development before herbicide application. Monitor the treated area in the late spring or early summer for
escaped plants and be prepared to spot-spray with Milestone (10 ml per 2.5 gal)1, Forefront (50 ml per 2.5 gal)1, or
Remedy (50 ml per 2.5 gal), plus surfactant and color marker, in the fall as needed. After spot-spraying, monitor this site
every 45-60 days to control TSA plants before fruit is produced. Be prepared to broadcast Milestone or Forefront again the
following December to control TSA seedlings have escaped the initial broadcast application and the subsequent spot-sprays.
- Sparse stands
Begin monitoring fields in October after TSA plants have recovered from the summer stress and resumed active growth. Spot-spray in
November/December with Milestone (10 ml per 2.5 gal), Forefront (50 ml per 2.5 gal), or Remedy (50 ml per 2.5 gal), plus surfactant
and color marker, as needed. Continue monitoring every 45-60 days and spot-spraying as necessary so TSA fruit is not produced.
