Mauget’s Tree Injection ArborFos is a phosphite formuled fungicide that inhibits fungal growth through stimulation of the plant’s own natural defense systems. Its mode of action is not completely understood but researchers indicate that it may elicit a type of Systemic Acquired Resistance response. Although it imparts no actual phosphorous nutrition, trees tend to develop healthier leaves, roots and stems. ArborFos is for use on conifers, ornamental, forest and certain crop trees for diseases such as Sudden Oak Death (P. ramorum) and has recently shown excellent results in Sycamore Anthracnose management programs.
