STRAWBERRY: FUNGICIDE EFFICACY - CONVENTIONAL

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.

* Registration pending in California.

** Not registered, label withdrawn or inactive in California.

¹ Code 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 Code number are suitable to alternate in a resistance management program. In California, make no more than one application of fungicides with mode-of-actions (MOA) with high resistance risk before rotating to a fungicide with a different MOA (Code number); for other fungicides, make no more than two consecutive applications before rotating to fungicide with a different MOA (Code number).

² To reduce the risk of resistance development, start treatments with a fungicide with a multi-site mode of action; rotate or mix fungicides with different mode of action FRAC numbers for subsequent applications, use labeled rates (preferably the upper range), and limit the total number of applications per season.

³ Foliar applications provide systemic treatment.

⁴ Ridomil Gold SL is the only formulation registered. If the GR formulation is applied to a previous crop that must be removed, it has a 0-day plantback interval.

⁵ More than 4 applications cause severe stunting.

⁶ Nonpersistent resistant populations of Botrytis cinerea to fenhexamid occur with repeated use of FRAC Code 17 fungicides.

⁷ Plant dip (nurseries) or foliar spray (field use).

⁸ Not for use in nurseries, on nursery transplants, or greenhouses (check label for details).

⁹ Bravo is registered under a 24c special local needs for nursery use only on non-bearing plants. It is used as a dip treatment of transplants.

¹⁰ Velum One is a fluopyram formulation for chemigation. Soil applications are designed for nematode management but may also suppress powdery mildew.

^R Resistant isolates documented in pathogen populations.

STRAWBERRY - FUNGICIDE EFFICACY - BIOCONTROLS AND NATURAL PRODUCTS

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.

* Registration pending in California.

** Not registered, label withdrawn or inactive in California.

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/).

² Efficacy rating determined with fungicide susceptible populations of pathogen.

³ Efficacy rating for soil applied control of Phytophthora crown rot.

⁴ Generic products may not be all listed and “etc.” indicates that other products may be available that have the same active ingredient.

⁵ More than 4 applications cause severe stunting

STRAWBERRY: TREATMENT TIMING

Note: Not all indicated timings may be necessary for disease control.

Rating: 3 = most effective, 2 = moderately effective, 1 = least effective, and 0 = ineffective

¹ Preharvest treatments include applications of fungicides before heavy fog, dews, or rain.

² Preplant fumigation includes chloropicrin, 1,3-dichloropropene/chloropicrin or chloropicrin followed by metam sodium

or metam potassium. Alternatively, make solitary applications of 1,3-dichloropropene/chloropicrin or chloropicrin.

³ To reduce risk of fungicide resistance development, use an integrated program that includes a rotation of fungicides with different modes of action.
