Presentation by Kurtis L. Schroeder, Cropping Systems Agronomist & Plant Pathologist, on Soilborne Diseases of Cereals: Identification and Management for the Integrated Pest Management Website hosted by Umatilla County Extension Service.
A species of bacterium common in soil and water called "Burkholderia cepacia" (B. cepacia) is being championed by agricultural scientists as a non-chemical means of fighting plant infections.
Wireworms are among the most destructive of soil insect pests. This publication explains the wireworm life cycle and describes a program for monitoring and risk assessment. Nonchemical management methods are suggested, including crop rotation, soil drying, flooding, cultivation, resistant varieties, soil amendments, early harvest, trap crops, and biological control. Includes photos for pest identification.
Topics covered include the life cycle of entomopathogenic nematodes; how they control insect pests; obtaining, using, and storing; soil conditions necessary; application preparation, equipment, and rates; pesticide safety; and websites that provide more specific information.
Scotch thistle was introduced to the United States in the 1800s as an ornamental plant from the Mediterranean region. It is a noxious weed in Idaho, Oregon, and Washington. Scotch thistle can form dense, virtually impenetrable stands in low- to high-fertility soils. This publication provides information for identification, management, and control.
Reviews Russian thistle biology as it relates to management, including seed dormancy and longevity in soil, seed distribution, seed germination and emergence, plant growth after establishment, crop competition, and resistance to herbicides. Outlines key considerations for managing for 3 crop years and 1 fallow year. Describes results from a residue management experiment designed to determine how to reduce tillage while maintaining winter wheat production.
Explains how simple and creeping perennial weeds reproduce and spread. Covers weed seedbanks, seed dormancy in soil, and factors that influence seed germination. Describes the typical root structure of perennial weeds and the various ways perennial weeds compete with crop plants for water, nutrients, and light. Discusses the advantages and disadvantages of various methods to control ...
A look at integrated pest management in "Concepts from Start to Finish".
Integrated pest management (IPM) is an ecologically-based pest control strategy that relies heavily on natural mortality factors such as natural enemies and weather, and seeks out control tactics that disrupt these factors as little as possible. IPM uses pesticides, but only after systematic monitoring of pest populations and natural control factors indicates a need. Ideally, an ...
