Fighting Phaeomoniella in Kiwis: Symptoms, Prevention and Professional Solutions

Phaeomoniella chlamydosporum is a deadly fungus that causes a devastating fungal disease in kiwifruit crops. Attacking fruit and plant tissue, this disease, also known as kiwifruit canker, causes significant losses both in the field and in storage.

This article explores the symptoms, prevention practices, and appropriate treatments for this disease. As a trusted partner, Kiwiverse, a wholesale supplier of kiwi plants, offers professional solutions to replenish your orchards and protect your future production.

What is Kiwi Phaeomoniella?

Phaeomoniella chlamydosporum is a pathogenic fungus that thrives in humid conditions and attacks kiwifruit at various stages of development. It affects not only the fruit on the plants, but also the harvest during storage, significantly reducing its commercial lifespan.

To limit damage and replant efficiently, it is recommended to purchase robust and resistant kiwi plants from specialist suppliers such as Kiwiverse.

Symptoms of Phaeomoniella in Kiwi Crops

On fruits

• Wilted appearance: Infected fruits dry out and become covered with grayish spots.
• Internal tissues affected: A waterlogged texture and dark green colors appear, making the fruits unfit for consumption.
• Black sclerotia: Irregular black dots (up to 5 mm) develop on the surface of fruits at an advanced stage.

On crops

• Post-harvest losses: Fruits deteriorate rapidly in storage, reducing their commercial value.
• Degraded aesthetic and textural quality: Fruits become unsaleable, leading to major financial losses.

Factors Promoting the Development of the Disease

Weather conditions

• Excessive humidity: Prolonged rainfall and inadequate irrigation promote the proliferation of the fungus.
• Poor drainage: Soil that retains water increases the risk of infection.

Unsuitable cultural practices

• Infected plant debris: Contaminated leaves or fruit left on the ground serve as a reservoir for the disease.
• Plant injuries: Cuts or mechanical damage facilitate the entry of the fungus.

Prevention in Organic Agriculture

Plant debris management

• Collect and dispose of infected fruit and leaves to limit the spread of the disease.

Soil improvement

• Add organic matter, such as compost, to strengthen the plants' natural defenses.
• Ensure good drainage to avoid standing water.

Specific fungicides
