Rating: 5 = excellent and consistent, 4 = good and reliable, 3 = moderate and variable, 2 = limited and/or erratic,
1 = minimal and often ineffective, 0 = ineffective, NL = not on label, ND = no data, NC = not coded in FRAC.

1 Group numbers are assigned by the Fungicide Resistance Action Committee (FRAC) according to different modes of action (for more information, see www.frac.info).
2 Efficacy rating for soil applied control of Phytophthora crown rot and leather rot of fruit.
3 Generic products may not be all listed and “etc.” indicates that other products are available that have the same active ingredient.
4 Apply at low rates since phytotoxicity (reddening of older leaves, slow growth and yield reduction) has been documented with repeated sprays.
