EPA Agrees to Ban Endocrine-Disrupting Pesticide Propazine

EPA today said it will end the use of the weedkiller propazine, reversing the Trump administration's embrace of the farm chemical shown to harm dozens of endangered species. Farmers use propazine in Texas and other states on sorghum fields, and it's sometimes used on container-grown plants. The agency didn't comment on the background behind the cancellation but said EPA had received no public comments in response to an announcement in March that it intended to take that action.

Supporting Homeowner IPM Programs, a survey

You are invited to participate in this survey about perceptions regarding pest control and integrated pest management (IPM) for home use. The study hopes to learn more about the public’s beliefs about integrated pest management and pest management practices and how they influence consumer behavior regarding pest control in the home. The survey will take approximately 10 minutes. Please share with your networks.


Are There Alternatives to Glyphosate for Weed Control in Landscapes?

People often ask about alternatives to glyphosate because of perceived concerns about health and environmental effects. Joe Neal and Andy Senesac, Extension Weed Specialists with NC State and Cornell, respectively, put together an excellent piece on alternatives to glyphosate for weed control in landscapes. This article from UMass Extension compares precautionary statements for some of these alternatives. It is the third item down.


Does vinegar kill weeds?

Montana State Extension fields many questions about alternatives to synthetic herbicides for weed control. One common question is whether vinegar, or acetic acid, works as an herbicide. The answer is, it depends!


Maine establishes the Maine Healthy Soils Program

Maine’s House of Representatives recently followed the lead of the Senate, voting unanimously to support LD 437 – An Act To Establish the Maine Healthy Soils Program. Broad bipartisan support for healthy soils indicates an increasing awareness of the critical role that agriculture must play in sequestering carbon and mitigating the effects of climate change. Maine joins 14 other states that have adopted healthy soils programs. Seventeen more states have healthy soils legislation pending.

This simple animation is a great introduction to the basic principles of sustainable livestock management and is intended to complement more detailed training materials.


IPM Practitioner, Bio-Integral Resource Center’s quarterly publication is out for April 2021, focused on Saving the Monarchs.

Over the past 20 years U.S. overwintering populations of monarch butterflies, Danaus plexippus, have been steadily declining. Since 1996, eastern populations overwintering in Mexico have declined 80-84%. But western populations that overwinter along the California coast have dropped more than 99%. Western populations have plunged from about four million in the 1980s to less than 2,000 in 2020. The western migratory monarch is on the brink of extinction.

Invasive Species

Asian longhorned beetle eradication efforts planned

In 2021, the ALB program will focus on inspecting trees in quarantined areas in Massachusetts, New York, Ohio, and South Carolina, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. Program officials will monitor for the beetle’s presence inside and around each area, respond to calls for assistance, conduct training sessions for compliance agreement holders, and perform outreach.


Insect pest eats into Lebanon’s White Gold pine nut trade

The culprit is the western conifer seed bug, native to the western United States where it is sometimes called the "stink bug", and which has spread to Eurasia, most likely by hitchhiking on timber shipments.


Invasive Pests to Worry About Before HABs Strike in Late Summer (Clean Your Boat’s Hull Before Launching)

The peak season for harmful algal blooms, or HABs, is at least two months away, but the Finger Lakes have plenty of other pests and invasive species to worry about before toxic algae takes center stage.


Undesirable Bluegrasses Poa Annua and Poa Trivialis becoming an invasive problem in lawns and landscapes

Rough bluegrass (poa trivialis) is native to Eurasia.  This makes it a non-native, invasive species here in North America.  It was likely brought to the US by early settlers for use in pastures and marshy areas. From Maryland Extension.


Climate Change Patters of Wild Blueberry Fields in Downeast, Maine over the past 40 years

The maximum, minimum, and average temperatures of the studied 26 wild blueberry fields in Downeast, Maine showed higher rates of increase than those of the entire region during the last 40 years. Fields closer to the coast showed higher rates of warming compared with the fields more distant from the coast. hese climate change patterns and associated physiological relationships, as well as threshold values, could provide important information for the planning and development of optimal management techniques for wild blueberry fields experiencing climate change


Effect of Vegetation on the Abundance of Tick Vectors in the Northeastern United States: A Review of the Literature

This literature review synthesizing research on the relationship between vegetation and tick abundance for four tick species in the northeastern United States. The blacklegged tick (I. scapularis) is associated with closed canopy forests and dense vegetation thickets. The American dog tick (D. variabilis) has little habitat overlap with I. scapularis, with abundance highest in grasses and open-canopy fields. The lone star tick (A. americanum) is a habitat generalist. The habitat associations of the recently introduced Asian longhorned tick (H. longicornis) in the United States are still unknown. 


Optimal Collection Methods for Asian Longhorned Ticks (Ixodida: Ixodidae) in the Northeast United States

They address the need for effective collection methods for host-seeking H. longicornis as an important step for accurately assessing tick abundance and potential disease risk.


Efficacy of Wolbachia-Infected Mosquito Deployments for the Control of Dengue

Distributing mosquito eggs infected with Wolbachia bacteria led to a dramatic fall in dengue cases and hospitalizations in areas that got the intervention compared with those that didn’t, researchers report. Article here.

North American Invasive Species Management Association’s (NAISMA) Online Invasive Species Management Certification Program, June 7- Aug 10, fee

Efforts to control invasive species are often piecemeal and under-funded. Compounding the problem is a lack of trained field specialists to lead/assist with control and management efforts. People seeking invasive species management positions usually have training in biology, forestry, agronomy, or related fields – but generally no training or field experience in controlling invasive species.  In response to this need, NAISMA is offering a unique college-level online professional development program to train Invasive Species Field Specialists. The program provides a comprehensive introduction to all aspects of ISM (Invasive Species Management) – including strategies and methods for Prevention, Early Detection and Rapid Response, and Control.
