Stone Fruit Regulations, W J. Hart

Journal of the Department of Agriculture, Western Australia, Series 4

Stone fruit grading regulations were introduced for the first time recently to keep small, green or badly blemished fruit off the market. This type of fruit is always in poor demand and can spoil the prices obtained for better lines of fruit by creating the impression of heavy supplies.

Shothole Of Stone Fruit, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Shothole disease is most damaging on almonds and early-flowering peaches and apricots but can also affect nectarines, plums and cherries.

The causal fungus IStigmina carpophila) survives the summer in infected buds and twig cankers.

The autumn rains then stimulate production of spores which infect other twigs, buds and subsequently the new spring growth.
