Integrated control of Phytophthora fruit rot (Phytophthora syringae) in stored Cox apples.

An integrated min. pesticide approach to control P. syringae fruit rot on apples was developed and tested. A system of rot risk assessment prior to harvest was developed based on certain factors. These factors were orchard rot history, fruit quality, % bare ground, % of the crop <0.5 m above the ground and rainfall. Using this system, pre-harvest predictions of rot due to P. syringae in fruit from 13 orchards agreed closely with the incidence of rot recorded in Mar. It is concluded that pre-harvest assessment of Phytophthora rot risk can be used to determine the need for fungicide treatment. Orchard experiments have shown that pre-harvest sprays of captan, metalaxyl + mancozeb, selective picking or the use of a straw mulch to cover the soil surface to prevent soil splash were all effective in reducing Phytophthora fruit rot. An integrated scheme for disease management based on rot risk assessment and available control measures is proposed.
