Harvanta 50SL works via contact and ingestion activity. It has anti-feeding activity. Translaminar, but not systemic. Thorough spray coverage is essential, and re-application may be needed to cover unprotected leaves if plants are growing rapidly. The minimum interval between treatments is 7 days. Foliar application is prohibited during flowering unless it is applied 2 hours prior to sunset until sunrise or when it is 50° F or less. Make only two consecutive applications of Group 28 insecticides before rotating to a different MOA.

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.
