General Information

Quali-Pro Lambda GC-O Insecticide is for use on turf and ornamentals in indoor and outdoor areas such as residential landscapes and nonresidential landscapes around institutional, public, commercial, and industrial buildings, parks, recreational areas, golf courses, and athletic fields.

Quali-Pro Lambda GC-O Insecticide may be applied to ornamentals grown in commercial greenhouses, shadehouses, and nurseries, and turf grown on sod farms or for commercial seed production.

Quali-Pro Lambda GC-O Insecticide may also be used for applications to golf course fairways, greens, greens aprons, and tee areas.


- Do not apply to flowering plants when pollinating insects are present. Make applications during the early morning or late evening hours.

- Do not apply this product through any type of irrigation system.

- Do not apply this product to edible crops or crops grown for food/feed.

- Do not apply this product by aerial application.


Quali-Pro Lambda GC-O Insecticide may be mixed with water and applied in all types of application equipment. Mix product with the required amount of water and apply as a dilute application to the point of runoff. Apply as a coarse spray using appropriate equipment. To avoid small droplets, do not use excessive spray pressure, and use the correct nozzle. For hard-to-wet foliage such as holly, pine, or ivy, use a spreader-sticker to increase knockdown and residual activity. If concentrate or mist-type application equipment is used, use the equivalent amount of product for concentrate or mist-type application equipment as would be used in a dilute application.

Note: Testing has been carried out on a wide range of ornamental plants under various environmental conditions, and no phytotoxicity has been observed; certain cultivars may still be sensitive to the final spray solution. Before treating large areas, prespray a selection of ornamental plants and observe them for 7-10 days if local use data is not available.

Limitations, Restrictions, and Exceptions



- Do not apply when turfgrass is waterlogged or when soils are saturated with water (i.e., will not accept irrigation).

- Keep children and pets off treated areas until spray has dried following the application.

Application Instructions

Make application to turf before high insect populations and turf damage is evident. Reapply at 7-day intervals if necessary to maintain control. Use higher rates when pest pressure increases.

Surface Insect Control (armyworm, cutworms, fleas, etc.): For best results, apply Quali-Pro Lambda GC-O Insecticide at recommended rates in 2-5 gals. of water per 1,000 sq. ft. If high rainfall amounts are forecast, the addition of a spreader-sticker may be helpful. For normal conditions for surface insect control on turf, the addition of adjuvants is not necessary. For best control of target pests, do not water or mow for 12-24 hours.

Fire Ant Control: Use 0.5 fl. oz. of Quali-Pro Lambda GC-O Insecticide per 2.5 gals. of water. Use a watering can to treat individual mounds as a drench application. Thoroughly soak each mound and a 3 ft. diameter circle around each mound. In order to avoid disturbing the mound, gently apply the mixture. Disturbing the mound may cause the ants to migrate and reduce the effectiveness of the treatment. For best results, apply in early morning or late evening hours. Make additional treatments as needed, but not more than every 7 days.
