Attentive readers may well remember a Nibble from a couple of months back announcing the “Discovery of genes for resistance to black Sigatoka in bananas”.
Rodomiro Ortiz writes on Host plant resistance genes for black Sigatoka in banana and plantain: two decades of research on the genetics and inheritance of host plant resistance to black Sigatoka in Musa. Black Sigatoka (or black leaf streak) is a major global constraint for growing one of our favorite fruits: banana and plantain (Musa spp.). The disease develops faster where humidity and rainfall are high. Yield loss to black Sigatoka ranges from 33 to 50% because this leaf spot disease affects negatively both fruit number and weight.
(Picture shows red thrip damage not Sigatoka - but a dead leaf with no fruit does not suggest banana! PHH)
