Miticide/insecticide for control of spider mites and leafminers. Toxic to fish and wildlife; highly toxic to bees. For foliar sprays addition of low rates of oil or other adjuvant, where advisable, may improve penetration and residual control. Performance will generally be best on tender, young foliage. Watch overspraying: ferns and some Shasta daisy cultivars have been injured by Avid sprays. Do not use or store near heat or open flame.

1Trunk injection for trees at least 2” diameter; labeled for control of elm leaf beetle only. Store at 45°F – 74°F. Do not freeze. 2Trunk injection; labeled for control of spider mites, leafminers, elm leaf beetle, sycamore lace bug, fall webworm, and pine nematodes; see labels for others. For post-bloom use only and (Mauget products) for trees at least 2” diameter. 3Also contains fungicide; not labeled for pine nematodes. 4Trunk injection for control of various mites and other pests on woody ornamentals and of pine wilt nematode on pines. For post-bloom use only and for trees at least 4” diameter.
