Coffee leaf rust is the most debilitating and widespread disease affecting coffee growers. It causes an estimated $1 billion in damage to coffee crops each year. Despite the significance and urgency, solutions are not well-known, and the ones that are well-known are not accessible to most farmers and tend to be ineffective in the long run. In response to the first rampant outbreak of rust in Latin America, rust-resistant coffee varieties were developed, promising farmers a future free of rust. Honduras aggressively adopted a rust-resistant variety called Lempira, replanting 42% of the country’s coffee lands with the lauded hybrid. Shortly thereafter, the supposed rust-resistant coffee trees were hit with an outbreak of rust. It turns out coffee leaf rust mutates rapidly and can evade genetic resistance and chemical controls. There are now 40 strains of rust and counting. Still, to this day, the majority of research, development, funding, attention, and credence goes towards the development of hybrids that will “ensure the future of coffee.” Coffee breeding is slow and expensive. It takes up to 15 years to produce a stable variety. Meanwhile, soil health, crop nutrition, and integrated management have all been overlooked, and often completely ignored. I’ve worked with several coffee farms to reduce coffee rust well below the threshold of economic damage by providing the trees with complete and timely nutrition, bringing the soil back to life, and using biological controls. In one case, rust incidence decreased from 20-40% down to 5% in a single season without the use of chemical fungicides. This isn’t to say that breeding is not important or needed – it is. However, it's not always going to be the most sustainable intervention, and a plant’s full genetic potential depends on adequate nutrition and healthy soil.

One of the best parts of teaching is working with bright graduate students like @botanyandbeans, who wrote her MA thesis on the recovery of Puerto Rico's coffee industry after Hurricane Maria. She summarizes this research in a recent post on @IICA news. Way to go, Justina!
Justina WM (she/her)@botanyandbeans

I wrote a blog article that was just published by @IICAnews! blog.iica.int/en/blog/coffee… (Based on my MA research conducted under supervision of @stuartmccook and @Silviasarapura1 and updated to reflect current situation)

@agecprof This never happens. You will never feel this. That’s a utopian fantasy.

@ViridianaHF @DJMontao1 That was a fantastic presentation, Viridiana! Aprendi mucho, y veo muchos paralelos entre el cultivo del aguacate, del café, y del cacao. Tenemos que conversar!

@BrownKnowser Happy New Year, buddy! Our day sounds pretty similar. Some writing, putting around the house, and being happily lazy and unproductive.
