General Properties of Fungicides Used in Kiwifruit

(Reviewed 4/13, updated 4/13)

In this Guideline:

Common name
(trade name)		 Chemical class Activity Mode of action
(FRAC number)1		 Resistance potential
cyprodinil (Vangard) anilinopyrimidine mostly contact, slightly systemic single-site (9) high
fenhexamid (Judge) 2 hydroxyanilide contact single-site (17) high
fludioxonil (Scholar) 2 phenylpyrrole contact few to multi-site (12) low
1  Group numbers are assigned by the Fungicide Resistance Action Committee (FRAC) according to different modes of actions (for more information, see http://www.frac.info/). Fungicides with a different group number are suitable to alternate in a resistance management program. In California, make no more than one application of fungicides with mode-of-action Group numbers 1, 4, 9, 11, or 17 before rotating to a fungicide with a different mode-of-action Group number; for fungicides with other Group numbers, make no more than two consecutive applications before rotating to fungicide with a different mode-of-action Group number
2 Judge and Scholar are for postharvest use only.
