Quadris Label Expanded to Leafy Greens, Pepper, Eggplant, Okra and Strawberry

Quadris is an effective broad spectrum fungicide whose label includes many crops and diseases. In a supplemental label dated November 29, 2001, the following new vegetable crops and diseases were added:

CropDiseasesRate
Brassica (Leafy Greens)white rust, black spot and basal stem rot caused by Rhizoctonia solani.6.2 to 15.4 fl oz of product per acre
Pepper, Eggplant and Okrapowdery mildew and anthracnose6.2 to 15.4 fl oz of product per acre
Strawberryanthracnose, powdery mildew and basal stem rot caused by Rhizoctonia solani.6.2 to 15.4 fl oz of product per acre

Quadris should be integrated into an overall disease management strategy that includes varieties with disease tolerance, proper timing of irrigation and removal of plant debris in which inoculum overwinters.

Do not apply more than two sequential sprays of Quadris before alternating with a fungicide that has a different mode of action. Do not make more than four application of Quadris per acre per crop year.

Quadris application should begin prior to disease development and continue throughout the season on a 7- to 10-day schedule, following the resistance management guidelines.

Do not apply more than 1.92 quarts of Quadris per acre per season.

Extensive work has been done with strawberries and management of anthracnose ripe fruit rot (http://www.smallfruits.org/Pestinfo/pestinf.htm). Specific recommendations are available for strawberries based on this research experience. For example, see http://ipmwww.ncsu.edu/current_ipm/palert27.html. Modified recommendations will be available in early winter for strawberry growers.
