Basil1

Leaf Spot (Colletotrichum sp.)

Symptoms: Dark spots form on leaves and the
dead tissue within leaf spots may drop out, causing a
shot-hole symptom. The disease can cause
defoliation, tip dieback, stem lesions, and sometimes
loss of entire plants. Spores are water-splashed from
diseased tissue.

Cultural Controls: Sow seeds in sterile
containers in sterile soil. Since wet conditions favor
disease development, reduce leaf wetness periods by
reducing humidity and increase plant spacing to
increase air movement. Avoid overhead irrigation.
Remove disease plants to reduce inoculum levels.

Bacterial Leaf Spot (Pseudomonas
cichorii)

Symptoms: Spots on leaves are water-soaked,
dark, and may be both angular and delineated by
small veins in the leaves or show as irregular leaf
spots. A wet stem rot may occur. Bacterium is
reported to be seed-borne. The disease is favored by
wet, humid conditions and is disseminated by


splashing water or by handling and spreading
infected tissue.

Cultural Controls: Decrease moisture on plants
with low humidity and sufficient plant spacing for
adequate movement to reduce leaf wetness periods.
Use disease-free seed and transplants. Remove
diseased leaves and plants to reduce inoculum levels.
Avoid overhead irrigation. Use clean, sterile
equipment and do not move between infected and
healthy plants.

Fusarium Wilt (Fusarium oxysporum)

Symptoms: Initial disease symptoms are
yellowing of the shoots, distorted young leaves, and
internal vascular discoloration of stems. As the
disease advances, plants wilt and die. The pathogen is
seed-borne and survives in the soil for many years.

Cultural Controls: Use disease-free seed in
sterilized soil. Seed may be disinfested. Rotate fields
away from basil. Some resistant cultivars are
reported.
