Description

Features

For introductory courses in weed science.

This introduction to weed sciences text prepares students to analyze real-life weed control problems and to develop integrated, practical approaches to solving them. Comprehensive in coverage and unique in presentation, it blends basic information on plant systems, soil systems, control methods, and management systems, and discusses various plants and herbicides by groups to provide an integrated framework from which to extend information to many different situations.

Hallmark Features

• Coverage of the characteristics, biology, and importance of weeds includes:
• Critical period of weed control.
• Seed banks.
• Seed dormancy – primary/secondary dormancy, innate/enforced/induced dormancy, and after-ripening.
• Economic losses caused by weeds.
• Invasions by exotic weed species.

• Coverage of weed life cycles to include a description of the location of growing points and their implication for regeneration of new plants after control measures have been applied.

• Material on methods of weed control – e.g. cover crops, allelopathy, and bioherbicides.

• Material on human health and environmental concerns regarding herbicide use, including groundwater issues, and how herbicides are evaluated for safety and registered with the EPA.

• Coverage of plant herbicide interactions includes sections on:
• Plant metabolic processes that aid in understanding herbicide modes-of-action.
• Modes-of-action of all herbicide groups.

• A detailed section on herbicide movement and persistence in the soil.

• In-depth coverage of herbicide groups with significant foliar use.
• Foliar herbicides grouped into three categories: translocated herbicides showing initial symptoms on new growth, translocated herbicides showing initial symptoms on old growth, non-translocated herbicides showing initial localized injury.
• Lists for each herbicide group and herbicide: Trade names/manufacturers, chemistry, available formulations, response in soils, sensitive species, major uses, special problems, and whether or not weed resistance has been documented.

• Coverage of herbicide groups applied almost exclusively to the soil.

• Section on weed control in conservation tillage systems.

• Sections on stage of crop and weed development for annual crops and turf.

• Stresses the grouping of information (rather than the listing of information) to provide a strong framework from which to extend information to many different situations, e.g.:
• Groups plants according to characteristics and life cycles.
• Groups weed control strategies for individual crops by crop life cycles and management systems (e.g., annual crops, herbaceous perennial crops, woody plants, etc.).
• Groups herbicides by mode of action and chemistry and presents the groups against a framework of how they are used and how plants respond to them.

New To This Edition

This edition is thoroughly updated to include

• Increased coverage of competition, resource allocation, seed banks, and other ecological principles. This helps professors and students consider how to utilize ecological principles in the development of integrated weed management programs.
• Increased coverage of herbicide resistance among weeds and the methods by which the incidence of such resistance can be decreased. This helps students understand the problems of herbicide resistance and how to counteract it.
• Two new chapters focus on invasive plant ecology, including the mechanisms of invasion. Students will benefit from an understanding of invasive plant ecology and how to manage invasive plant species, which influence public lands (such as parks and forests).
