barryb Posted June 23, 2020 Share Posted June 23, 2020 Ok Hesi, despite spraying stacks of copper oxy on my Apples I still get black spot, help. Quote Link to comment Share on other sites More sharing options...
Hesi Posted June 23, 2020 Author Share Posted June 23, 2020 Copper is a contact fungicide, been used in Bordeaux mixture probably since before even you were around, that forms a protectant barrier against fungal spores, instead try a commonly available systemic one such as https://www.bunnings.co.nz/yates-fungus-fighter-200ml_p0707454 Fungal probs are usually a sign of poor air movement, so make sure your trees are well pruned to allow plenty of air movement through the trees Quote Link to comment Share on other sites More sharing options...

Hesi Posted June 23, 2020 Author Share Posted June 23, 2020 Everything is dormant now, so give the trees a spray with lime sulphur, kills everything, gets the populations of all the nasty diseases and bugs down, then once all your new foliage has come through in the Spring, and hardened up, that's when to use the systemic fungicide Apple fritters to go with the whitebait Quote Link to comment Share on other sites More sharing options...
