What is HydroSeeding?

Every year in the United States, there are at least 20,000 confirmed cases of Lyme disease, a painful but treatable tick-borne illness.But now, experts are warning of a faster-acting, untreatable and potentially fatal sickness called Powassan virus that is most commonly found in the same tick that hosts Lyme disease.

Within two to three hours of being bitten by a tick infected with Powassan virus, a person may develop headaches, nausea, vomiting, muscle weakness, memory loss and speech difficulty. While people with Lyme disease develop lesions and a rash, those who get Powassan virus do not. In severe cases, the Powassan virus can infiltrate the central nervous system, causing inflammation in the brain and spine, and leading to encephalitis meningitis, said Dr. Theodore Andreadis, director of The Connecticut Agricultural Experiment.

“It’s (Powassan virus) not something pleasant,” Andreadis, whose organization is a Connecticut State-run agricultural research agency, told FoxNews.com. “We’re not putting any major alarm out there, but we’re saying we need to be aware of this because we do appear to be seeing a re-emergence of it.”

The virus is found in about 2 to 3 percent of the ixodes scapularis, the primary tick that hosts Lyme disease and the Powassan virus, while Lyme disease is found in 30 to 40 percent of them, Andreadis said. But unlike Lyme disease, which can take a couple of days to infect the person bitten after the tick latches onto his or her skin, the Powassan virus can transmit in a fraction of that time.

“The point being, if you find a tick feeding on you and you have the opportunity to get it off you within a few days, and it’s Lyme disease, you might be OK,” Andreadis told FoxNews.com. “With the Powassan virus, ticks will inject the virus within a matter of hours.”

 
Also, unlike Lyme disease and another tick-borne illness— such as the malaria-like Babesiosis, which stems from a microscopic protozoa called Babesia— Powassan virus cannot be treated by antibiotics. People who become infected with the virus have only supportive care available. It is thought to be fatal 10 percent of the time, Andreadis said.

Spotting these specific ticks can prove challenging, as their nymph stage is about the size of a poppyseed, according to the Centers for Disease Control and Prevention (CDC). The reason why Andreadis and his colleagues worry over a rise in cases this year is the virus’ favorite host, the white-tailed deer, are growing in population in Connecticut, where Andreadis’ team is based, and in the Northeast.

“With the increased forestation in the state and in the Northeast, the deer herd have increased exponentially, then the ticks have increased, and now the virus,” he said.

These specific tick-borne illnesses appear to crop up the most in the northeastern United States: In 2013, 95 percent of the confirmed Lyme disease cases were reported in this part of the country.

That year, the most recent data available, there were 12 confirmed human Powassan virus in the U.S., compared to seven in 2012 and 12 in 2011, according to the CDC. The Powassan virus was first identified in 1958, and ever since there have been 70 human cases reported, Andreadis said.

Durland Fish, professor of epidemiology at Yale University, who has spent his career studying Powassan virus and other tick-borne illnesses, said the number of actual human Powassan viruses is likely higher. That’s because many public health agencies haven’t developed tests for the virus and may mistake it as Lyme disease, or not spot the virus in people who may have both Lyme disease and Powassan virus. He added that in some regions of the U.S., the virus has been found in anywhere from 5 to 10 percent of ixodes scapularis ticks.

“We’re seeing some [Powassan] cases and some deaths, but not in proportion to what we’d expect to see considering how many ticks are infected,” Fish told FoxNews.com. “These ticks transmit five other kinds of diseases that we know about, so here’s another one. We know people are getting Lyme disease and Babesiosis because there’s tests for them, so there’s no reason to expect people aren’t getting this virus.”

Andreadis advised hikers and campers, or anyone going into a wooded area with low-lying brush— conditions that support tick populations— to wear long pants and tuck them into their socks, which can make spotting ticks easier.

“Examine yourself closely when you leave the area because these ticks will attach and begin to feed very quickly,” he said. “They like to attach around the waist, behind your knees, and even below your hairline. You want to check yourself quite closely.”

HydroSeeding which is sometimes also called hydraulic mulch seeding, hydro-mulching, or hydraseeding) is a planting process in which a slurry containing seed, hydro seeding mulch, fertilizer and a tackifier (bonding agent) is sprayed onto the ground. The slurry is transported in a truck or trailer mounted tank to the job site and sprayed over prepared ground in a uniform layer. In remote areas hydro seeding is sometimes also done using helicopter. Hydro seeding offers many advantages to the traditional process of broadcasting or sowing dry seed. It promotes quick germination and inhibits soil erosion. It is also a very cost effective alternative to sod and offers a significant cost savings as well as many other benefits.
Virtually any grass or erosion control seed that can be planted by seed can be hydro seeded. This includes any sun or shade lawn seed, athletic field mixes, pasture mixes, native grasses, wildflowers, roadside mixes and erosion control mixes. The nutrient rich slurry helps promote fast germination. The hydro seeding mulch helps keep the soil moist to enable the seed to germinate quickly and unlike straw or hay contains no weed seed. The tackifer in the mix acts like a glue to hold the mulch in place and to help prevent washout in the case of heavy rains.
How HydroSeeding Works
Advantages Of HydroSeeding Over Broadcast (Dry) Seeding
Quicker Germination
Better moisture retention
Better seed to soil contact
Better results at a similar cost
No straw or netting to remove
One step and very uniform application
Holds soil in place better than dry seeding
Areas such as hillsides and narrow areas that are difficult or impossible to dry seed can be done easily
Hydro seeding mulch contains no weed seed unlike straw or hay
Advantages Of HydroSeeding Over Sod


• You can have a sod quality lawn in a few weeks for less than 1/3 the cost of sod
Both hydro seeding and sod require watering but the watering requirements for hydro seeding are less
Hydro seeding grows the lawn on your soil and is not a different soil that is transplanted
• The problem of sod not “taking” is eliminated.
• With sod the roots are cut very short and the sod goes through some shock during shipment and installation

HydroSeeding In Place Of Erosion Control Blankets
With some of the newer hydro seeding materials that have come on the market it is now possible to save time and money by seeding difficult areas that formerly required labor intensive erosion control blankets.
    Products such as BFM (Bonded Fiber Matrix) and FGM (Flexible Growth Media) will provide superior erosion control and fast turf establishment with up to 8 times less labor than erosion control blankets. Unlike blankets these erosion control products bond directly to the soil surface and both hold better and require less surface preparation. On less demanding applications standard hydro seeding materials do an excellent job.
