Screening As Part of Insect and Disease Management in the Greenhouse


Screening Insect and Disease Management in the Greenhouse


Robb and Parrella (1988) described a greenhouse screening experiment in California in which they were able to grow a crop of chrysanthemums without a single application of pesticides. This article describes some of our efforts with screening materials for excluding greenhouse pests inspired by those workers. Most of our emphasis has been with the western flower thrips, a vector of the tomato spotted wilt virus. We also used the sweetpotato whitefly. These two relatively new pests are remarkably resistant to pesticides and cause considerable damage to greenhouse ornamentals.
