Weed Control in Pickling Cucumber Bernard Zandstra Michigan
Weed Control in Pickling Cucumber Bernard Zandstra Michigan State University Great Lakes Expo Grand Rapids, MI December 4, 2018
Objectives for 2018 1. Determine whether tillage before planting makes a difference in weed control and cucumber yield. 2. Obtain data to support a Reflex label on cucumber. 3. Test bicyclopyrone for safety on cucumber.
Experiment HF 2018 Tilling 1: May 25 (Half the field) Tilling 2: June 4 (Whole field) Planting: June 6 (Whole field) Harvest: July 20 (44 days after planting)

Summary 1. Two tillings (12 days and 2 days before planting) had slightly better com. ragweed control and slightly less wild radish control. Other weed control was similar. 2. Two tillings had more yield than one tilling 3. Highest yield from Curbit + Command + Reflex and Curbit + Command + Sandea treatments.
Other Herbicide News 1. Command – reduction of PHI to 30 days is under review at EPA 2. Command label – maximum of 0. 25 lb/a (0. 67 pt) 3. EPA may require 1, 200 foot buffer for all use of clomazone, including Strategy, which currently does not have the 1, 200 foot restriction. 4. EPA will require coarse droplet nozzles for all clomazone use.
