Littleleaf Disease Management Practices
Nurseries or Seed Orchards
| Management Practices |
Littleaf Disease |
E. Use seeds or seedlings that are
resistant or less susceptible to
disease. |
Avoid planting littleleaf-susceptible pines on sites with a previous history of littleleaf disease or on high-hazard sites for the disease (Table 2). These sites should be regenerated with seed or seedlings from:
- Loblolly seed orchards, or
- Nonhost species, such as hardwoods.
|
| G. Modify fertilization practices. |
In high-value stands showing early symptoms of disease, fertilize with up to 250 pounds of inorganic nitrogen per acre (39.5 kg/ha). |
