Hi fellow ALSers
Looking for a way to control Apple scab any recommendations for sprays, preferably something not to toxic would be great.
Thanks for any help received. 🙂
According to organic Gardening magazine use Cupric hydroxide, sulphur or activated potassium bicarbonate sprays.
This from ‘What Garden Pest or Disease?’ by Judy McMaugh (can’t recommend her book highly enough – it really is a bible of garden pests/diseases with lots of great photos and suggestions for how to control them). So, she says:
Organic/non-chemical: Rake up and bury all leaves in the autumn.
Chemical: Regular applications of fungicides are necessary. Spray with copper oxychloride or copper hydroxide, at greentip stage (early to med-September), and again 14 days later. Then spray every 14 days with mancozeb. Stop about the end of October unless the weather is wet.
** You can buy copper hydroxide as Yates Fungus Fighter – I use this on most of my fruit trees – a little goes a long way **
