Brigade 2EC can be applied to soil or to foliage. The active ingredient, bifenthrin, is more stable in soil than other pyrethroids, which makes it a viable choice for soil insect control. Brigade 2EC has contact and ingestion activity. It is toxic to many kinds of insects with a relatively long duration of impact from residues on leaves. This and other pyrethroid insecticides (Group 3) should not be used mid-season because they kill predatory insects that help to keep aphids, psyllids, thrips, and spider mites in check. Brigade 2EC is not systemic or translaminar, but residues generally persist on foliage for 7-14 days. Use high water volumes with ground or aerial applications to ensure the product is well distributed in the foliage. Make only two applications, and do not make them less than 21 days apart. Similar products containing bifenthrin are available, including package mixes, but use rates vary.

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.

If early nymphs are present, it may not control the nymphs on the underside of leaves where the product is not well distributed. |
