DuPont Authentication Velpar H - 65190 - Manual (Page 10)

USE PRECAUTIONS
• Do not apply through any type of irrigation system.
• Do not apply within 90 days of harvest.
• Do not apply to flooded field with standing water.
• Application to blueberry foliage will result in crop injury.
• Since the effect of DuPont™ VELPAR® DF on
blueberries varies with soil type, plant vigor, uniformity
of applications and amount of rainfall, it is suggested that
growers limit their first use to small areas.
LOW BUSH BLUEBERRIES
VELPAR® DF may be used for the control of certain weeds
in low bush blueberries.
APPLICATION INFORMATION
VELPAR® DF may only be applied to pruned blueberry
fields in the spring before leaf emergence. Using calibrated
ground spray equipment, make the application in sufficient
water to provide thorough and uniform coverage to the
treated area (usually 20 gallons per acre). Shut off spray
booms when starting, turning, slowing or stopping, or injury
to the crop may result.

after treatment, reduce rate in future applications.
• Maintain a 50 foot buffer from any well head or water
reservoir.
