Who am I?

Anthracnose is the name of a common fungal disease; some species are host specific and others have multiple hosts. Besides causing damages to crops in the field, anthracnose is an important postharvest disease that favors periods of extended cool and wet weather.

Symptoms of anthracnose vary depending on the host, and the infected plant part. Symptoms include: mild and irregular, brown to black spots on leaves and fruits, blighting, and dieback of twigs and branches.

Control measures

Cultural

The sooner the better: It’s easier and more cost effective to overcome infestation and control anthracnose during the initial stage of infestation. Make it a routine to monitor the field regularly and search plants for the presence of anthracnose on a weekly basis.

Sanitation: Sanitation measures are important: Keep your fields’ close surroundings clean from weeds and old plant debris.

Pruning: When possible, take out infected plant parts.

Conventional (chemical)

Organic

Copper-based fungicides

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides and Herbicides). It is the grower’s sole responsibility to keep track after the legal uses and permissions with respect to the laws in their country and destination markets. Always read the Instructions written on the label and in any case of contradiction work with accordance to the product label. Keep in mind that information written on the label usually apply only to local markets. Pests control products intended for organic farming are generally considered to be less effective in comparison to conventional product. And so one must keep in mind that when dealing with organic, biologic and, to some extent, small number of conventional chemical products, a complete eradication of a pest or a disease will often require several iterations of a specific treatment or combination of treatments.
