In the San Joaquin Valley, the warm weather has stimulated quite a bit of fall flush. Citrus leafminer loves these new leaves and is attacking all varieities of citrus vigorously. While the damage is unsightly, most varieties of mature trees can take this damage and continue to grow at a normal rate. Nursery trees, new plantings, limes, and lemons with multiple crops in coastal California need insecticides to reduce the damage.
