Attachment 3 - Phragmites Control Chart - 08.20.2026.pdf

This document is an excerpt from a technical guidance document on phragmite management, specifically presenting Table 3 which illustrates three integrated, multiyear approaches for managing phragmites across a three-year period.

The table outlines three distinct management approaches, each spanning three years with monthly breakdowns. Approach 1 emphasizes herbicide treatment with imazapyr during July of Year 1, followed by herbicide treatment with glyphosate or an imazapyr/glyphosate combination in September. Approach 2 implements a prescribed burn during February-March of Year 2, with subsequent spot treatments using imazapyr (if necessary) in July and glyphosate or imazapyr/glyphosate combination in September. Year 3 under Approach 2 includes mechanical treatment in October through December. Approach 3 primarily relies on spot treatments with imazapyr (if necessary) in July and glyphosate or imazapyr/glyphosate combination in September across multiple years, with treatment intensity potentially varying based on management outcomes. All three approaches present optional ("OR") treatment alternatives, allowing for flexibility in implementation based on site-specific conditions and resource availability. This document serves as a reference guide for land managers or environmental professionals implementing phragmite control strategies.
