Legislative Action

The below bill is being considered by the Agriculture, Conservation and Forestry Committee

LD 1770 – “An Act to Improve Pesticides Sales and Use Data Collection and Accessibility by the State”

  • The bill directs the Board of Pesticides Control, to create an online database for pesticide product dealers, certified applicators and commercial agricultural producers to report the type and amount of pesticides sold, distributed or applied in the State and other information as required. The bill specifies a certified applicator or commercial agricultural producer to report the names of all pesticide product dealers from which pesticides were purchased, the address where the pesticides were applied, the names of the pesticides, the quantity purchased and applied, the date the pesticides were applied and the EPA registration number. The bill specifies that information submitted is public information but allows a pesticide dealer, commercial applicator or commercial agricultural producer to request that the board designate proprietary information as confidential.

      A public work session is scheduled for May 10, 2023, at 11:00 AM

  • UMaine Extension Tick Lab adds Powassan virus and Heartland virus to tick testing service. The University of Maine Cooperative Extension Tick Lab is adding two new pathogens to its tick testing panels. The Tick Lab will now be screening ticks for Powassan virus and Heartland virus in addition to testing for the pathogens that cause Lyme disease, anaplasmosis, babesiosis, Rocky Mountain spotted fever, ehrlichiosis and tularemia. Powassan virus is a rare but serious pathogen that can be transmitted by infected deer ticks, woodchuck ticks or squirrel ticks; Heartland virus has been linked to the bite of a lone star tick. Powassan virus can cause severe neurological symptoms and is a potentially fatal illness. 

Integrated Pest Management (IPM)

The BPC promotes the principles and implementation of IPM and other science-based technology to minimize reliance on pesticides while recognizing that outbreaks of disease, insects and other pests will necessitate fluctuations in pesticide use.

  • As we all know too well, tick season is upon us. There are important Integrated Pest Management principles that can help you navigate through this challenging season.
