David Grays PHOS INJECT 200 1 litre
I have a one litre container of David Grays PHOS INJECT 200 Fungicide. I have used 15ml only, it is virtually new. This is 200g per litre (g/L) concentration of Phosphorous as Phosphonic acid
Online prices vary from $35 to over $50 depending on postage or not. So $20 is good value in my opinion. I bought this for some conifers with die-back but only used 15ml as a diluted foliar spray. Now not required.
Description from David Gray site:
Phos Inject 200 is a systemic fungicide used for the control of root rot in avocado, root rot and foliage die back in ornamentals. Also used for citrus, root rot in subteranean clover caused by Phytophthora Fungi and for the control of downey mildew in grapes.
Phosphite (phosphonate), is a biodegradable fungicide that can help fortify and protect some plants against the Phytophthora dieback. Phosphite works by boosting the plant's own natural defences and by assisting susceptible plants to survive die-back.
