Use and Care Manual

reducing systems may be utilized if they control spray drift as well as Nalco-Trol or
the above mentioned booms. If a spray thickening agent is used, follow all recom-
mendations and precautions on the product label. Do not use a thickening agent
with the Microfoil or Thru-Valve booms or other systems that cannot accommodate
thick sprays.
Dormant Stem Applications
To control susceptible woody species such as multiora rose and blackberry, mix 1
to 4 gallons of this product in diesel oil, No. 1 or No. 2 fuel oil or kerosene to make
100 gallons of spray and apply to thoroughly wet upper and lower stems including
the root collar and any ground sprouts. Treat at any time when the brush is dormant
and the bark is dry. Best results have been obtained with late winter to early spring
applications. Do not treat when snow or water prevent spraying to the ground line.
For the most susceptible woody species such as blackberries, substitute other dilu-
ents or oils only in accordance to manufacturer's recommendations. Apply mixture
to thoroughly wet upper and lower stems as described above. The more tolerant
species may require total oil carrier for better control. Brush over 8 feet in height is
difcult to treat efciently. Basal or mechanical methods may be better suited for
control of large trees.
Conventional Basal Bark and Stump Applications
For control of susceptible woody plants and to prevent or control regrowth from cut
stumps, mix 4 gallons of this product in diesel oil, No. 1 or No. 2 fuel oil or kerosene
to make 100 gallons of spray mixture. Spray the basal parts of brush or trees to a
height of 15 to 20 inches from the ground. Thoroughly wet all the basal bark area
including crown buds and ground sprouts. Spray runoff should visibly wet the ground
at the base of the stems or trunks. Basal and cut stump applications can be made at
any time of the year except when snow or water prevent spraying to the ground line.
Best results have been obtained with winter to early spring applications. Basal treat-
ments are less effective on trees with diameters larger than 6 to 8 inches. For better
regrowth control, cut the larger trees and treat the stumps. Treat stumps the same as
the trunks and also treat the freshly cut surface. The cambium layer just inside the
bark is the most important area of the cut surface to treat.
