This course explores the biology and control of diseases and insects in turf grasses, shade trees and shrubs. It concentrates on the nature and type of agents that cause ornamental plant diseases and insect pest problems. It includes the cultural control of ornamental plant pests through an understanding of the conditions that promote or lead to the problems. It also focuses on the groups of important pests of conifers, broadleaf landscape plants and turfgrasses.
Landscape practitioners and gardeners wishing to gain plant protection skills.
