Elsinoe fawcetti and Elsinoe austealis
A fungal disease also known as Citrus scab or Verrucosis that causes raised warty lesions to appear on fruit and leaves, often causing the leaves to buckle. While the disease doesn’t cause major problems it should still be treated as it negatively affects the health and vigour of the tree, making trees more susceptible to other problems.
Fruit is still edible, though less attractive.
Spores of the fungus are spread during wet weather and are dispersed by rain splash and wind. They live in the corky growths on the fruit and leaves, fruit remain susceptible for up to 3 months after petal fall.
To reduce the risk of your trees being affected by this fungus, ensure they are planted in full sun, in free-draining soil rich in organic matter. When pruning your trees prune to open up the center of the tree to allow better air flow.
When watering, water well and deeply so that the water reaches the roots and does not run off the top of the soil. Well watered plants are less likely to come under attack then plants suffering from moisture stress.
In addition a regular spray program will help prevent and keep Verrucosis under control.
Spray with Grosafe FreeFlo Copper Fruit and Vegies before and after blossom fall.
Spray with Yates Copper Oxychloride before flowering and again at 3-4 weekly intervals up until harvest.
Remember prevention is better than cure. Therefore regular spraying is important.
When using sprays and chemicals always read the label and follow instructions carefully. Spray in the evening to avoid harming beneficial insects.
