Would it be appropriate to use this product as a soil drench for Boxwood Blight that is spreading through a bed that also contains Little Gem Magnolias. The boxwoods are turning brown and some Magnolias leaves have black spots, others are yellowing, turning brown, and falling off. Are there other products you would recommend to save my landscaping? Thank you.
Agrisel BioPhos Pro Systemic Fungicide should be used both as a soil drench in water applied to the root zone and as a foliar spray to run-off on listed plants. For root treatment, use 2 Tbs per gallon of water. For foliar spray, use 4 Tbs per gallon of water and apply to runoff. Both boxwoods and magnolias are listed as tolerant species on the product label of this fungicide. We do recommend identifying the specific issues with your plants for best results so that you have a complete treatment plan.
