NEMATODE FACT FILE

Nematodes are microscopic worm-like organisms that attack the roots of plants.  Damaged roots result in a reduced uptake of nutrients and water.

 

Pome fruit is primarily attacked by root-lesion and dagger nematodes.  Root-knot nematodes, which cause the characteristic galls on roots, do not attack pome fruit.  Due to the absence of these galls it is […]

SmartFresh™: The Latest Innovation in Fruit Storage. Some preliminary results on South African pome and stone fruit.

SmartFresh™ is an exciting new breakthrough in the postharvest storage of fresh fruit and vegetables. American scientists at North Carolina University invented 1-methycyclopropene (1-MCP), an antagonist ethylene inhibitor in horticultural products. The technology, now known as SmartFresh™, has been aquired and developed for use on fresh fruit and vegetables by AgroFresh Inc, a Rohm […]

PLUM RIPENING PROTOCOL

Plums are grown in South Africa mainly for the export market. Consequently, most plums are harvested with extended cold storage periods in mind. Plums are therefore harvested mature, but not ripe and are normally ripened en route to the overseas markets. Sugar levels in these fruit are normally adequate for the plums to develop […]
