Screening Insect and Disease Management in the Greenhouse
Resistance to pesticides has made control of insect and mite pests increasingly difficult in the greenhouse.

However, with aphids or western flower thrips, the number of pesticides which are effective and labeled for use in the greenhouse is uncomfortably small.
