Field management of avocado postharvest diseases.

Strobilurin fungicides were found to be effective in controlling postharvest diseases of 'Hass' avocado. Of the three strobilurin formulations tested in the field (in Queensland, Australia) on 'Hass', the Amistar and Flint fungicides were found to be superior to the Stroby formulation. The incidence of anthracnose (caused by Colletotrichum gloeosporioides [Glomerella cingulata]) was significantly reduced by 66 or 74% when Amistar or Flint was applied as a foliar spray. Rootstock studies conducted on 'Hass' found rootstock race had a significant impact on postharvest anthracnose susceptibility. This is the first record of such an effect for avocado. The incidence of anthracnose was on average 34-35% significantly lower for 'Hass' grafted on the Guatemalan 'Velvick' rootstock as compared with the Mexican 'Duke 6' rootstock.
