Pests and Disease Common to Artichoke
Grey Mold- Also known as Botrytis rot (Botrytis cinerea). The fungus that causes gray mold invades the plant and flower bracts that have been damaged by slugs ,frost, insects, or other factors. Infected plants turn brown on the outside. On the inner surface is the characteristic gray growth . The fungus survives on decaying organic matter. Botrytis rot is most common during rainy weather. Plant in well-drained areas. Remove infected plant parts and protect plant buds from damage caused by invertebrates. When storing chokes, remove infected chokes immediately.
Any fungicides registered for grey mold control must be applied before infection takes place, they won't cure an existing infestation. If you've had problems with gray mold in the past apply fungicide before the infestation gets to the plant.
- Avoid injuring the foliage. Damaged foliage from Fertilizer-burn or frost- is much more susceptible to grey mold infection.
- Avoid densely spaced seedlings growing levels by selecting a container that allows adequate spacing for seedling development. Containers can also be placed at a wider spacing to allow better air circulation during periods when seedlings are especially vulnerable.
- Follow a strict sanitation policy that includes removal and destruction of all plant debris, prompt removal of infected seedlings, and sterilization of containers ,growing area and surfaces between plants.
- Avoid excessive moisture, and allow for proper aeration to reduce the presence of moisture for more time than is actually necessary.
Curly Dwarf - plants lack vigor , growth is stunted. Leaves become distorted and have dark, localized dead spots . Infected plants produce much smaller yields . Severely affected plants die.
Rogue diseased plants. {remove and destroy}
Use only disease-free Crowns .
Artichoke curly dwarf virus is NOT seedborne, the use of artichoke seed and resulting transplants will greatly reduce the probability of the disease re-occurring in new plantings.
Artichoke Plume Moth University of California : Artichoke Plume Moth Slugs and snails are a major problem on perennial artichokes especially in winter. They feed on all parts of the plant. Slug feeding on foliage causes shot holes on the leaves. Slugs are particularly injurious to the buds when they scrape off soft tissues from the artichoke bracts. This injury later turns black and the quality of the affected produce is greatly reduced. See Controlling Snails and Slugs
