2007 Evaluation of One and Two Fall Applications of Various Herbicides for the Control of English Daisy (Bellis perennis) in Lawns
Preliminary Report
02/28/2008
Purpose
The purpose of this trial is to evaluate one and two applications of various herbicides for the control of English Daisy (Bellis perennis) growing in lawns.
Materials & Methods
Roundup Tolerant Tall Fescue/Perennial Ryegrass Trial
Introduction:
Previous work reported by Crystal Fricker at Pure Seed Testing Inc. demonstrated that it is possible to develop tall fescues and fine fescues that have relatively good tolerance to low rates of glyphosate. This trial is part of an ongoing effort to evaluate tolerance of tall fescues and other grasses to glyphosate at rates that are effective in controlling annual bluegrass.
Fertilizing Lawns
Explains how to optimize a fertilization program for a home lawn. Discusses how to select and use fertilizers, the roles of various elements (nitrogen, phosphorus, potassium, sulfur, pH, calcium, magnesium, and iron) in lawn fertilization, and the value of soil tests for each element. Provides sample calendars of necessary and optimal times for fertilizer applications for western, central, and eastern Oregon.
