What are the dilution rates for Yates Rosesheild Concentrate?
Lost Rose Shield concentrate leaflet of directions. Please advise dilution per litre for black spot on roses. Thanks. If you could email the leaflet that would be great.
Yates Rose Shield should be diluted at 10ml per 1 litre of water. The solution should be sprayed thoroughly including the undersides of the foliage. Begin spraying when new shoots sprout in spring or at first sign of insect pests and disease. Repeat at 14 day intervals if required.
