Eutypa lata

Eutypa lata is a fungal plant pathogen of grapevines.^[3][4] The fungus also attacks many other hosts such as cherry trees, most other Prunus species, as well as apples, pears and walnuts. In apricots, the fungus reveals a canker surrounding a pruning wound.^[5]

Eutypa lata was first found in Californian grapevines by English et al.1962,^[6] a few years after its discovery elsewhere.^[7] Travadon et al., 2011 finds that E. lata is an entirely or almost entirely sexual population here but asexual reproduction may be a rare occurrence.^[8]

It causes 'Eutypa dieback' in New Zealand grapevines as well.^[9]

The fungus was difficult to identify on the basis of colony morphology and could be out-competed by other fungi when isolated from wood. DNA isolated from one year old canes can be used instead.^[10]
