Sh­eryn’s rec­om­mended or­ganic con­trol for home or­chards

NZ Lifestyle Block - - Cover Story -

Hang moth traps in the tree as soon as blos­soms start to ap­pear. Spray with a cater­pil­lar bio­con­trol a week to 10 days af­ter traps start catch­ing adult moths or at 80% petal fall. Re­peat in 10 days. Re­fresh traps and leave out to mon­i­tor for an­other gen­er­a­tion later on in sum­mer. Early sea­son in­fec­tion of the fruit is of­ten by way of the cat­lyx and can be hard to see. How­ever the cater­pil­lar can be ac­tive in­side the fruit as in­di­cated by brown frass around the tell-tale hole. Re­mov­ing and dis­pos­ing of in­fected fruit can help con­trol num­bers.

Re­mov­ing any fruit you find with tell-tale brown ‘frass’ around the en­try hole helps to con­trol num­bers.
