EPG-Admin: add "brush control" link to 822.10 Maintenance Planning Guidelines for Brush Cutting

2008-03-10T15:06:06Z

add "brush control" link to 822.10 Maintenance Planning Guidelines for Brush Cutting

New page

[[image:821.20.jpg|right|280px]]
'''Definition:''' The control of undesirable trees, shrubs, sprouts and tree limbs. Also referred to as [[822.10 Maintenance Planning Guidelines for Brush Cutting|brush control]].

'''Why:'''

1. Reduces need for frequent mechanical removal

2. Efficient way to control spread of undesirable woody plants

'''Primary Targets:'''

1. Cut stump – sprout regrowth

2. Areas containing invasive woody growth

3. Areas where woody vegetation is creating a sight distance hazard

4. Highway sign clearance

5. Clear zone – same definition as vegetation policy

6. Side trimming to reduce shading

'''Methods:'''

'''A.''' Calibration

Most products applied with handgun or backpack sprayer (see section on calibration of handgun sprayers)

'''B.''' Recommended products and rates

'''C.''' P.P.E.

Follow manufacturer’s label recommendations

'''D.''' When to apply

:a. Krenite should be applied from mid through late summer (before fall color change)

:b. Other foliar applied chemicals can be applied throughout the growing season however high temperatures and drought can reduce effectiveness

:c. Basal bark applications can be effectively applied as a dormant season treatment

:d. Cut stump treatments need to be applied shortly after cuts are made (within 15 to 30 minutes) to be effective and only to the outer edge of the cut surface

'''Special Recommendations:'''
[[image:821.20 Do not mow.gif|right|225px|thumb|<center>'''Do not mow vegetation treated with Krenite for one year after application'''</center>]]
'''A.''' Read the label

'''B.''' Location Concern

:a. No applications over rivers, streams, or ponds

:b. Avoid treatments near desirable woody vegetation

:c. Avoid treatments near crops

:d. Do not mow or trim vegetation treated with Krenite for one year after application

'''C.''' Weather

:a. Since applications sometimes are made up into tall vegetation, spraying during very low wind conditions is essential

:b. High temperatures and drought conditions can lessen effectiveness

:c. 2,4-D products are not to be applied in temperatures above 700

'''D.''' Clean-up and Disposal

:a. Follow label recommendations for disposal of unused product

:b. Escort requires constant agitation; no mixed product should be left in the tank

'''E.''' Mode of Action

:a. Systemic herbicides (2,4-D) are absorbed through leaf tissue and translocated through the plant

:b. Non-systemic herbicides (Krenite) control the vegetation only where applied

:c. Basal bark treatments are absorbed through the bark. They are only effective on thin barked, mostly young trees

:d. Cut stump treatments are carried through the exposed vascular system into the roots
