Follow-up

Survival
End of 1st growing season ?
End of the 2nd growing season?
Once height growth initiates ?
Follow-up

Survival
 Free -to Grow
 Competition
Survival
 Minimum number ?
 250 -300 per acre
 landowner objectives
 Distribution
 evenly distributed?
 Replanting - interplant pro’s and con’s
Competition
• Vegetative Competition
• Grasses a problem early
• Woody species later on
• Hardwoods
• Loblolly
Competition Control

Herbicides
Prescribed Burn
Mechanical
Herbicides
• The best time to treat competitive
vegetation is prior to planting
Herbicides
• Herbicide rates are higher on clay sites
and sites with high organic matter.
Higher rates needed for effective control
may be toxic to young LL seedlings
• pH increases the efficacy of OUST
TM.
Decrease to 1oz. Per acre if pH is > 6.0
Herbicides
• High quality sites, especially those with
grass component, will require one maybe
two release treatments
Herbicides
• Herbicides are generally less effective in
drought conditions
• Stressed LL seedlings more susceptible to
toxic effects (Don’t apply unless 3-4 inches of
new root growth is present)
• Fall planted seedlings may be less susceptible
• Application timing is critical
Prescribed Burn
• LL fire -resistant in the grass stage
• minimum 1/2 RCD
• Susceptibility increases after height
initiation
• Fire resistance increases for trees greater
than 4 feet high and greater than 3” ground
line diameter
• Low-intensity fire
Prescribed Burn
• Loblolly susceptible up to sapling size
• Repeated prescribed burns needed to control
hardwoods
• Growing season burns more effective
• Good for Wildlife, good ecologically
• Repeated burns will effect growth and thus
yield
Mechanical
•
•
•
•
Drum Chopper- between the rows
Chainsaws, brush saws, machetes, etc
Labor intensive
environmental friendly
Pest Control
 Less susceptible than other SYP
 Fusiform rust - rarely a problem
 Pitch Canker - locally somewhat
 Brown spot needle blight - major disease, not
as severe in NC
 SPB- does not infest severely
 Ips Beetle -after lightning
 Turpentine Beetle following fire
 Pales Weevil
Brown Spot Needle Blight
• Effects Needles and slows growth
• Prolongs grass-stage
• Continued severe infestation causes
mortality
• Controlled by prescribed burn
Pales weevil damage
on Longleaf seedling
• Web worm damage to
a three year old LL
sapling
