Disease Management in Enclosed Spaces

Disease management in an enclosed space poses a unique set of issues that must be addressed when controlling pests and disease. Safety for personnel is a key issue as well, as exposure to pesticides is increased. This course teaches the basics of pest and disease management in this unique space, and the different tools and techniques needed to successfully control the environment.

After completing this chapter participants will be able to:

  • Gain an understanding of the issues involved in controlling pests and disease in an enclosed space.
  • Tailor a management strategy that addresses the unique needs of an enclosed space environment.

Integrated Pest and Resistance Management

Integrated Pest Management. Integrated pest management, or “IPM” for short, is an environmentally sound approach to controlling a pest population through common sense methods. Each control method will be addressed and defined in this presentation. IPM is a strategy focusing on the long-term prevention of pests or their damage through the use of multiple techniques.

Basics of Sampling for Plant Pathogens. Pathogens are often the root cause of plant failure. Implementing an effective strategy using chemicals to target an identified pathogen is an essential element of agricultural stewardship. This course teaches the basics of sampling, and the different tools and techniques needed to accurately identify crop pathogens.

Insect Identification. Insects are a major part of our daily lives. Whether we realize it or not, there are millions of insects around us at all times. This presentation is a brief overview of basic identification of insects that we commonly come in contact with. At the end of this presentation, I hope that you have a better understanding of how to identify insects that you might encounter in work or in your day-to-day activities.

Pesticide Calibration. Calibration ensures that your equipment delivers the correct amount of pesticide uniformly across your field or target area and if done incorrectly or not at all has major consequences. It can mean the difference between control or failure of a pesticide. This course ensures you will be able to accurately calibrate using many types of application methods: broadcast application, banded application, multiple nozzles per row, and in-furrow applications.

After completing this chapter participants will be able to:

  • Monitor and control pests through cultural, biological, mechanical, chemical, genetic, and host plant resistance methods.
  • Describe resistance, how it develops, and integrative ways it can be managed.
  • Identify the characteristic differences between arthropods and insects, and the stages of metamorphosis.
  • Describe the different calibration types and why it is so important to calibrate before pesticide application occurs.
  • Become familiar with specific details and mathematical instructions on how to perform broadcast applications, banded applications, multiple nozzles per row, and in-furrow applications.
