Fusarium Efficacy Summary & Literature Review – 2018

Research Summary Abstract

From 2001 to 2015, numerous products representing 32 active ingredients were evaluated in greenhouse and field trials as soil drench, soil incorporation, foliar, in-furrow, drip irrigation or tuber soak applications against several Fusarium species causing rots (crown, stem and tuber rots) and wilt on ornamentals, and wilt and root rot on vegetables. Fusarium species tested included: F. avenaceum, F. commune, F. oxysporum, F. solani and F. sp. Most trials were conducted on F. oxysporum on larkspur, lisianthus and watermelon. Although there were insufficient data for definitive conclusions, several relatively new products showed promising, though inconsistent, efficacy comparable to the standards. These include Adepidyn (pydiflumetofen), Heritage (azoxystrobin), Compass (trifloxystrobin), Hurricane (fludioxonil+mefenoxam), Insignia (pyraclostrobin), Insimmo (acibenzolar), SP2169, Tourney (metconazole) and Trinity (triticonazole). BW240/RootShield Plus (Trichoderma harzianum & T. virens), CG100 (caprylic acid), Pageant (boscalid+pyraclostrobin), Palladium (cyprodinil+fludioxonil) and SP2550 provided no to mediocre efficacy. Proline (prothioconazole) provided consistently good control of F. oxysporum in watermelon trials. The established standards 3336 and Medallion generally provided inconsistent efficacy while Terraguard was effective in one trial.
