Assess your spray equipment. Use a sprayer that is capable of generating a very fine droplet size. Many pesticides registered for herbs such as insecticidal soap and horticultural oil kill by contact, so achieving good spray coverage is crucial. Early detection and treatment early in the crop cycle will result in better pest control. Plant canopies are smaller then and will allow for better coverage.
Biological control can be a realistic option for herb growers.
It takes commitment and time to learn pest identification and life cycles, and to investigate the various biological control methods. It also takes a successful scouting program in place. There are many places to find information on biological control. The table below provides a list of selected materials labeled for managing insects and mites on herbs. Growers are reminded to read and follow instructions on every label of every product before using it on herbs.
