CRITICAL COMMENTS
RATE OF APPLICATION Boom Spraying: Apply TEEDAL in 200 litres of water
per hectare. The rate of application will vary according to district
and the density of
the barley grass infestation.Use 7 kg/ha on close grazed pastures
(less than 5cm) or in the drier regions having an annual average
rainfall of less than 760mm.
Use 9 kg/ha in areas with a higher rainfall e.g. Waikato, Taranaki,
Coastal Otago and Southland, or when treating dense infestations
around stock camps, along
fence lines or where pasture is not closely grazed (greater than 5cm)
e.g. dairy pastures, or where treatment is delayed until August.
Gun Spraying as a spot treatment: (non crop areas), mix 900g of TEEDAL
per 100 litres water and apply as a wetting spray. (Avoid spray runoff
and excessive soil
contamination). Use No.4 tip at 350-700 kPa pressure and lightly but
evenly wet all the foliage.
METHOD OF APPLICATION Boom Spraying: Broadcast Treatment: To obtain
maximum control of barley grass in pasture with minimum pasture damage
the
application of the recommended rate of TEEDAL must be precise and
thorough without excessive overlapping. The spray equipment should be
completely free of
foreign matter which could cause a blockage. Correctly calibrated
vehicle mounted spray equipment is necessary for accurate broadcast
application. All nozzles
should be checked with water for an even distribution of the spray
pattern before mixing TEEDAL THE BOOM SHOULD BE SET AT THE CORRECT
HEIGHT
ABOVE THE PASTURE TO AVOID STRIPPING EFFECTS. For treating along
fencelines, around water troughs and under trees, the use of a boom
extension
nozzle such as a Teejet OC 12 off centre tip is recommended.
SPRAY ADDITIVES: DO NOT mix any other weed killers or surfactants with
TEEDAL spray solution as this may cause a serious loss in selectivity
to the desirable
pasture species.
