Spray Prevention Guide for Stonefruit Trees

Pests and diseases can significantly affect the appearance of the tree and the fruit, as well as affecting the general health and vigour of the tree if badly infected. Prevention is much more effective and successful than trying to cure once infected. Spring is an important time of year to maintain the spray programme, as pests and diseases are more active and the tree is opening up through the buds.

MAJOR PESTS & DISEASES AFFECTING STONEFRUIT

Leaf curl and brown rot. 

MINIMAL SPRAY PROGRAMME

AUTUMN

Apply a strong dose of Copper oxychloride immediately after leaf fall. 

 

SPRING

Copper oxychloride at green tip and again 10 days later. If mites, scale and aphids have been a problem a spray of Conqueror oil should be applied just before swollen bud stage.
