Many landscape maintenance professionals have grown reliant on glyphosate for weed control. Landscape weed control without glyphosate is certainly possible but will require more planning, careful consideration of alternative treatments, more frequent site visits, and higher costs. This publication discusses alternative treatments, their properties, uses and limitations.
This factsheet covers the identification, distribution, and control of Mugwort (also known as chrysanthemum weed), an aggressive, perennial weed that spreads by persistent rhizomes.
This pesticide factsheet covers the use and characteristics of Reward (diquat dibromide).
This pest control guide was a project of the Southern Nursery IPM Working Group (SNIPM) and collaborators. It is intended to provide up to date information about pest control products used in nursery crops and ornamental landscape plantings, and as a supplement to the more comprehensive integrated pest management (IPM) manuals for trees and shrubs. Recommendations for the use of agricultural chemicals are included in this publication as a convenience to the reader.
This publication details how to achieve accurate and uniform application of herbicides using hand-held applicators in container nursery settings.
This pesticide factsheet covers the use and characteristics of StriCore (pethoxamid).
This publication discusses the impacts of yellow nutsedge on sweetpotato crops and includes information on weed identification and management.
This pesticide factsheet covers the use and characteristics of Gemini (isoxaben + prodiamine).
Color guide to identification of weeds common in container nursery crop production. Also includes a table of preemergence herbicide efficacy on these species.
This publication discusses best practices for managing and controlling weeds in container nurseries and greenhouses, focusing on woody plant propagation and containerized liner production.
Efficacy of preemergence herbicides labeled for use in nursery crops and landscape plantings
Even the best herbicides will not provide effective weed control if they're not applied accurately and uniformly. This publication describes the steps required to calibrate hand-held spreaders commonly used in container nurseries.
This pesticide factsheet covers the use and characteristics of Gallery (isoxaben).
Preemergence herbicide efficacy summary chart, Ranking the efficacy of preemergence herbicides on most weeds of nursery and landscape plantings.
This publication provides guidance to Extension agents on how to design and conduct trials and demonstrations on alternative products for plant and soil health and pest and disease control purposes. It provides standardized experimental design criteria and best practices for planning and executing trials for these products.
Palmer amaranth is the most common and most troublesome weed in North Carolina sweetpotato. This publication discusses Palmer amaranth identification, reproduction and growth habit, impacts on sweetpotato yield and quality, and weed management options.
How often are you weeding? Is it frequently enough to prevent the next generation of weeds? Many of the most common weeds of container nurseries flower and produce seeds within 30 days. Our research suggests that you should be removing emerged weeds every 2 to 3 weeks. This publication offers information on some common container weeds.
Sanitation is an under-utilized component of container nursery weed management. Nursery sanitation is a commitment to weed prevention and management throughout the nursery and throughout the production cycle. This publication describes strategies to prevent weeds from spreading into and within container nurseries.
Various mulches, including fabric or organic disks, plastic pot-toppers, and organic mulches, have been investigated for weed control in containers. Advantages, disadvantages, and cost estimates, of using mulches in container nursery crops are presented.
A few weed species in North Carolina have become pervasive across the state and are frequently found in different crops. They form dense populations and reduce yields, making production more challenging. This publication discusses herbicide-resistant biotypes in agronomic and vegetable crops in North Carolina and reviews herbicide resistance management recommendations.
