PLANTING DELAY AFTER
USE OF BURNDOWN HERBICIDES
A common practice in conservation-till systems is use of
‘burndown’ herbicides for preplant weed control. Remember that time
restrictions with crop planting after herbicide application may exist. The
following are examples of label restrictions for several preplant burndown
herbicides:
*Landmaster BW - “Do not plant any crop other than
wheat, barley, corn, oat, rye, or sorghum (grain or forage) for 3 months after
treatment or until this product has disappeared from the soil”.
*Fallow Master BroadSpectrum - “Delay planting of
wheat, barley, oat, or sorghum (grain or forage) for 15 days after applications
of this product. Do not plant any crop other than corn, wheat, barley, oat,
rye, or sorghum (grain or forage) for 3 months after application or until this
product has disappeared from the soil”.
*Aim - Corn, grain sorghum, wheat, barley, oat,
buckwheat, pearl millet, and proso millet may be planted any time following an
application of Aim. All other crops may be planted after 30 days following an
application of Aim. Follow rotation restrictions on tank mix products if they
are more restrictive.
*2,4-D (4 lb/gal concentrate) burndown for soybean -
Days before seeding: 0.75-1 pint/A ester = 7 or more, 0.75-1 pint/A amine = 15
or more, 1-2 pint/A ester or amine = 30 or more. Seed soybean at least 1.5 to 2
inches deep to ensure separation from the herbicide.
Always read and follow herbicide label directions.
