Weed control with penoxsulam/oxvfluorfen for season long weed control in almonds

摘要

A study was conducted near Firebaugh, CA to evaluate dormant-season applications of penoxsulam/oxyfluorfen for season long weed control in almond orchards. Plots were 10 by 22 ft arranged in a randomized complete block design with four replications. Treatments were applied with a C02 pressurized backpack sprayer calibrated to deliver 20 gallons per acre with three flat fan XR8002 nozzles spaced 20 inches apart (Table 1). Environmental conditions during applications are presented in table 2. At the time of application, few shepherd's purse and fleabane seedlings were present. Weed control/densities were determined on March 10, April 12, June 3, and July 26, 2011.
