Management
In all cases of the disease, thorough study of the distribution and intensity should be determined to help choose a management practice that’s cost effective. For example, if the disease is widespread in a pre-commercial stand, destroying the plantation may be the most effective measure. The area can then be replanted with immune or low-susceptible species. Aerial surveying is a viable tool available for use in areas where there are severely damaged systems. Other management tools include:
- Using up to date models to help predict the spread of the disease can help with management choice
- Susceptible species should not be planted within 100 feet of a disease center
- Remove as many infected roots and stumps as possible to avoid inoculation of healthy plants
- Cut all infected trees within the disease center and all uninfected trees within 50 ft of the disease center
- Stumping is an expensive, yet effective measure in gently sloping, high-quality sites with light soils. After an excavator removes the stump, pieces of the root are torn and fragmented so invading soil organisms deter long-term inocula.
- Push-falling is an alternative to post-harvest stumping. Whole trees are pushed over with machinery to expose diseased roots for removal. Push-falling is effective in areas with slopes less than 30 percent and soil textures that are sandy to sandy loam.
- Applications of chemical fumigation (such as chloropicrin) have been unsuccessful in dealing with Laminated root rot.

Famous quotes containing the word management:
“Why not draft executive and management brains to prepare and produce the equipment the $21-a-month draftee must use and forget this dollar-a-year tommyrot? Would we send an army into the field under a dollar-a-year General who had to be home Mondays, Wednesdays and Fridays?”
—Lyndon Baines Johnson (1908–1973)
“The management of fertility is one of the most important functions of adulthood.”
—Germaine Greer (b. 1939)
“No officer should be required or permitted to take part in the management of political organizations, caucuses, conventions, or election campaigns. Their right to vote and to express their views on public questions, either orally or through the press, is not denied, provided it does not interfere with the discharge of their official duties. No assessment for political purposes on officers or subordinates should be allowed.”
—Rutherford Birchard Hayes (1822–1893)
