WHAT THE EVIDENCE SAYS
Fifty Castanea sativa saplings were given fosetyl-Al by injection at different doses or a soil treatment, then challenged with Phytophthora cinnamomi. Injected groups showed shorter necrotic lesions and less root infection, but phytotoxic leaf injury increased with dose and two high-dose plants died.
WHY IT MATTERS / OUR READ
Intervention success should measure unintended tree injury alongside pathogen suppression, before moving treatments into restoration practice.
CAVEATS / UNCERTAINTY
Young saplings under semi-controlled challenge, not mature wild trees. Reported model-derived minimum doses are not field instructions.
