Landscape, Nursery, and Turf - Comparisons of Neonicotinoid Insecticides
Neonicotinoid insecticides have been important tools for controlling tough insects in ornamental plants such as aphids, whiteflies, mealybugs, and scales. The following are comparisons of the different products on the market. Click on table for a larger image in a new window.

Nursery and Landscape - Newer Insecticides and Their Use.
Over the last 4-5 years, many new insecticides have been registered for use in horticultural applications. The following are some of these as well as informtion on some new uses for older insecticides.
Tristar (acetamiprid). This is a neonicotinoid insecticide available as a foliar spray for control of aphids, mealybugs, caterpillars, scales, whiteflies, thrips, leaf-eating beetles and leafminers. Nursery and landscape.
Safari (dinotefuran). A neonicotinoid insecticide used as a foliar spray or soil drench for control of whiteflies, aphids, scales, leafminers, mealybugs and other insects. Nursery and Landscape.
Celero (clothianidin). A new neonicotinoid insecticide for aphids, whiteflies and mealybugs in ornamental crops. The same active ingredient is labeled as Arena for use in turfgrass. Arena provided great control of grubs in turf, even surpassing Merit in our trials last year. Nursery and Landscape.
Discus (imidacloprid + cyfluthrin). Soil directed sprays in late June or July should be lightly covered with soil or watered-in immediately after application for optimum control of grubs. Discus is also excellent for aphid control and will help suppress scale insects and mealybugs. Allow four weeks after soil application for uptake by roots and movement into the leaves. Foliar sprays will control a wide spectrum of insects because of the cyfluthrin. Nurseries.
Flagship (thiamethoxam). Soil-directed sprays in June followed by rain or irrigation will control Fletcher scale and other scale insects and aphids. This insecticide seems to work better for soft scale insects than imidacloprid. June applications will also provide grub control, although July is the optimum timing for grubs. Nurseries
Distance (pyriproxyfen). Although not a new product, recent research tests in Indiana showed that Distance gave the highest level of control of euonymus scale of any product tested. This means it should also work well as a crawler spray for pine needle scale, oystershell scale and any armored scale insects. Nursery or landscape.

Landscape - Neonicotinoid Insecticides for Systemic Insect Control in the Landscape
The neonicotinoid insecticides have been extremely useful for control of hard to kill insects in the landscape such as scales, adelgids, leaf miners, and mealybugs. The following are some slides on the use of these insecticides as systemic treatments in the landscape.
