Avoid the Introduction and Spread of Invasive Plant Pest and Disease

Apr 03, 2024

April is Invasive Plant Pest and Disease Awareness Month, and the Virginia Department of Agriculture and Consumer Services (VDACS) encourages the public to help reduce the threat that invasive plant pests and diseases pose to the Commonwealth’s agricultural and natural resources.

Non-native, destructive insects, plant diseases and harmful weeds are a tremendous threat to the Commonwealth’s crops and forests, and can seriously harm the economy, environment, and even human health. Once invasive pests become established, they can grow and spread rapidly, often because they have no natural predators in their new environment and limited management options.

Invasive species, such as the Asian Longhorned Beetle, Spongy Moth, Imported Fire Ant, Spotted Lanternfly, Boxwood Blight, Vascular Streak Dieback, Thousand Cankers Disease, Wavyleaf Basketgrass, and Purple Loosestrife can wreak havoc on the environment, displace or destroy native plants and insects, severely damage crops and potentially cause the closure of foreign markets to U.S. products that originated from infested areas.

Taking steps to prevent their introduction is the most effective method of reducing both the risk of invasive species infestations and the cost to control and mitigate those infestations. The following are a few simple steps to help avoid and stop the spread of invasive pests:

Don’t move firewood over long distances as it can be a carrier of invasive insects and diseases. Use firewood that originates from the area where it will be burned. Spotted Lanternfly and Spongy Moth eggs can hitch a ride on firewood and start infestations in new areas.
Before leaving a work or recreational site, look for and remove any insects, seeds and other plant parts that might be attached to your equipment, boots, gear, and vehicle.
Consult with your local nursery or master gardener to select plants that are not invasive for landscaping and gardening projects. A wide variety of beautiful native plants that thrive in your local environment are available at local nurseries and garden centers.
Don’t plant seeds of invasive plants in wildlife food plots.
Always declare any plant material brought into the United States when returning from a trip abroad.

Anyone suspecting an invasive plant pest or disease in their area should contact VDACS’s Office of Plant Industry Services at ReportAPest@vdacs.virginia.gov, USDA’s Animal and Plant Health Inspection Service at 804.226.5262 or their local Virginia Cooperative Extension Service agent.

Video: Spring 2026 weather outlook for Wisconsin; What an early-arriving El Niño could mean

Northeast Wisconsin is a small corner of the world, but our weather is still affected by what happens across the globe.

That includes in the equatorial Pacific, where changes between El Niño and La Niña play a role in the weather here -- and boy, have there been some abrupt changes as of late.

El Niño and La Niña are the two phases of what is collectively known as the El Niño Southern Oscillation, or ENSO for short. These are the swings back and forth from unusually warm to unusually cold sea surface temperatures in the Pacific Ocean along the equator.

Since this past September, we have been in a weak La Niña, which means water temperatures near the Eastern Pacific equator have been cooler than usual. That's where we're at right now.

Even last fall, the long-term outlook suggested a return to neutral conditions by spring and potentially El Niño conditions by summer.

But there are some signs this may be happening faster than usual, which could accelerate the onset of El Niño.

Over the last few weeks, unusually strong bursts of westerly winds farther west in the Pacific -- where sea surface temperatures are warmer than average -- have been observed. There is a chance that this could accelerate the warming of those eastern Pacific waters and potentially push us into El Niño sooner than usual.

If we do enter El Nino by spring -- which we'll define as the period of March, April and May -- there are some long-term correlations with our weather here in Northeast Wisconsin.

Looking at a map of anomalously warm weather, most of the upper Great Lakes doesn't show a strong correlation, but in general, the northern tiers of the United States do tend to lean to that direction.

The stronger correlation is with precipitation. El Niño conditions in spring have historically come with a higher risk of very dry weather over that time frame, so this will definitely be a transition we'll have to watch closely as we move out of winter.
