How to Manage Pests

UC Pest Management Guidelines


Kiwifruit

General Properties of Fungicides Used in Kiwifruit

(Reviewed 3/07, updated 3/07)

In this Guideline:


Common name
(trade name)
Chemical class Activity Mode of action
(FRAC number)1
Resistance
potential
fenhexamid (Judge) 2 hydroxyanilide contact single-site (17) high
fludioxonil (Scholar) 2 phenylpyrrole contact few to multi-site (12) low

1 Alternating pesticides with different modes of action is important in preventing the development of resistance. Rotate chemicals with those that have a different mode-of-action Group number, and do not use products with the same mode-of-action Group number more than twice per season. Group numbers are assigned by the Fungicide Resistance Action Committee (FRAC). For more information, see http://www.frac.info/.
2 Judge and Scholar are for postharvest use only.
