The MIDA men came and so did my additional guest, Giovy from Aboquete. Today those in attendance learned about the three major coffee diseases found here in the Boquete District.
Ojo de Gallo and Roya are both fungus diseases that are airborne and decimate coffee plants. We learned about how they spread and how to control them. La Broca is a boring insect which is less of a problem at high altitudes.
Ojo de Gallo
Ojo de Gallo is a disease caused by the fungus Mycena citricolor. The problem is widespread on farms here and appears in sectored lights due to climate factors, host field position and agronomic management, ventilation, among others. It occurs mainly in mountainous areas where there is high humidity (above 80%), temperature around 20 ° C, excess shade in coffee plantations and susceptible varieties. The damage it causes is that the fungus causes leaf drop, fruit, death of young shoots and cause poor performance. The fungus survives in lesions observed on old leaves, fruits sporadically in patients who were on the ground or branch diseased tissues. These lesions are whitish, dry appearance and have about an inch in diameter. This fungus survives from year to year and that is where the primary inoculum originates, or who initiates the disease. In young leaves the shape of the spot is larger and irregularly shaped.

Roya is the return of a most destructive fungus, once eradicated and now back.
These are images of a coffee plant and leaf with Roya, also known as coffee rust. The images below and much more information are available at this LINK.
In both cases the use of fungicides, whether chemical or natural is the solution. MIDA advised about both and our second speaker Giovy Rojas from Aboquete provided detailed information on their fungus eating funguses which seem to be the best environmental solution available now and eats both Roya and Ojo de Gallo funguses . Their webpage appears dated but this is a link for contact information LINK
La Broca is less of a problem here but again there is a fungus that attacks and destroy the insect available from Aboquete.
We ran out of time today and will have still another meeting focused on Roya Sept 10.
