Pre/Post Treatment Plant Surveys Page
This page provides a compilation of documents that have been found on the internet or provided by applicators or lake managers related to the application of the herbicide Renovate (active ingredient Triclopyr). Some of the documents are state specific application permits and others are pre/post treatment plant surveys of treated lakes. Most of the lakes are in the north east, however collection of data was specific to New York State.
  • Herbicide Information Page- general and specific information about two of the herbicides (Renovate and Sonar) that are NYS registered for the control of milfoil. MSDS, Product Labels, Environmental Impact Statements, FAQ's, etc.
  • Plant Surveys (Eagle Lake) Page- Surveys of Eagle Lake that studied either individually or in combination the location and distribution of native vegetation or the locations and distributions of the invasive Eurasian Water Milfoil.
  • Plant Identification Page- Provides resources to help with aquatic/terestrial and native/invasive plant identification.
