Aphids that colonize many leafy vegetables are often named for crops that they frequently infest. Confusion may arise when different common names are used to identify a particular pest species. Incorrect identification may result in the use of less effective pesticides designed for a specific target pest. In Maricopa County, growers and crop consultants can get a pest identified by bringing a sample to this office.
Weeds are more easily identifiable if they have flowered.
A fresh sample is best but if delayed for several hours or days, especially during the summer, place the plant between paper towels and press it in the thick Phoenix telephone book to preserve it. Moths and butterflies should be kept dry to preserve the scales on the wings. Some live insects may be collected on the infested plant in a re-sealable plastic bag and kept cool in an ice chest if they can be brought to the office immediately after collection. For suspected plant diseases, collect root samples in a re-sealable plastic bag and include moist soil with the roots but do not add water. Fresh foliage samples usually travel best in a re-sealable plastic bag, but do not add water.
