  • IMLVT's first harvests

    Project Update

    Date: 2.11.19

    When World Coffee Research (WCR) formed in 2012, one of the first initiatives the organization launched was the International Multilocation Variety Trial (IMLVT). Each of 24 participating country planted the same 31 varieties. Most of the trial sites were established in 2016, and earlier this month, the first coffee cherries began to arrive. Here, photos of the first harvest at one IMLVT site in Guatemala.

Such natural control exists because every organism in nature has a range of natural enemies—competitors, parasites or predators—that are capable of reducing the size of its population. In the wild, coffee leaf rust has its own range of natural enemies.

  • The correlation of shade and rust

    Project Update

    shade and rust

    Many existing approaches for controlling coffee leaf rust are one-sided: Use rust-resistant varieties, or spray with as much fungicide as you can afford. But it is increasingly evident that we need to open new fronts in the fight against coffee leaf rust.
