Actara(thiamethoxam)

General Information

Actara has contact and ingestion activity. Translaminar and foliar systemic (moves to new leaves, but not downward). A spray adjuvant may improve coverage for ground or aerial application. Don’t use stickers. Chemigation may be best when the canopy is dense; use 0.2-inch water or less and the highest allowed rate. Don’t apply Actara or other neonicotinoid insecticides (Group 4A) if one was applied at planting or at hilling. Make only two consecutive in-season, foliar applications of Actara.

1Mode of action. NC = not classified..
2 Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
3 Rate per acre per application. Refer to the product label for maximum use rate per season.
4 Reentry interval.
5The minimum pre-harvest interval. Some products do not list PHI.
Note: always read and follow the directions on the pesticide label.
