Association Survey Help Combat the Invasive Mile-a-Minute Vine The Problem: Be on the lookout for the non-native and invasive Mile-a-Minute vine (polygonum perfoliatum L.) that is invading the lower Hudson Valley. It has been called the kudzu of the northeast because of its very aggressive nature. The vine can grow up to 6 inches a day and reach lengths of more than 23 feet a year! Prickly stems and leaves allow it to climb over surrounding vegetation and form dense, tangled mats that shade out the sun and choke underlying vegetation. This can lead to a decrease in biodiversity while reducing the aesthetics of the landscape. The annual vine is easily recognizable by its triangular leaves, downward facing prickles, ocrea (circular leaf surrounding the stem), and iridescent blueberry-like fruits that appear in late summer. The Solution: Government agencies and other organizations have been collaborating to launch an early detection and rapid response to this invasive in the lower Hudson Valley in order to eradicate the vine when possible and halt the it's expansion in New York State. CCE educators Dianne Olsen (Putnam) and Tolly Beck (Rockland) have been working closely on this project. Feel free to contact them for more information. Early detection and rapid response includes: detection of the vine, control of infestations, and monitoring of controlled sites for signs of recurrence. Hand pulling the vine and cooking it in the sun in black plastic bags is the best way to combat this invasive. How to Help: Volunteers are needed to survey areas and look for new infestations, control known infestations through hand pulling, and/or monitor controlled sites for signs of recurrence. To report an infestation or to volunteer please contact Kristen Fix at 845-758-7015 or kmfix@gw.dec.state.ny.us.

Gerald Nagahashi a chemist/cell biologist at ERRC, has been focusing on the events that must occur before the fungus can colonize a host plant. He developed a bioassay showing that host root components--including chemical compounds exuding from the roots, root caps and root border cells--induce fungal hyphal branching. The increase in branching creates a greater potential for the fungus to find and attach to the host root surface. Nagahashi and David D. Douds, an ERRC microbiologist, investigated how environmental factors, such as chemical compounds from host roots, blue light from the sun's spectrum, and carbon dioxide, affect AM fungal growth, either individually or together. Their techniques involved growing host roots in sterile culture and using sterile fungal spores to study various environmental factors individually or in combination. They found that these three factors--root chemicals, blue light and carbon dioxide--can all work independently to promote growth in AM fungi but are even more effective when applied together.

The system is the brainchild of a team assembled over the past three years by Charles Krause, research leader and plant pathologist in the ARS Application Technology Research Unit at Wooster. ARS is the U.S. Department of Agricultures principal scientific research agency. Although the lessons learned in the research are still experimental, they're already being adopted so rapidly by nursery operators that some in the industry expect the ARS monitoring system to be commercialized within the next few years. Nursery managers have reduced water use by 40 percent or more by applying these lessons. The system monitors plant needs year-round, currently using 30 sensors for each of three sets of 50 trees. Tests are being done at Willoway Nurseries in Avon, Ohio, on Red Sunset maple, redbud, and Chanticleer pear trees. The sensors and a weather station linked to computer data loggers take readings every minute, 24 hours a day, during the growing season of measurements such as soil temperature and moisture. The tests are being done with an increasingly popular production technique called pot-in-pot,in which potted plants are set inside holder pots permanently buried in the field. This especially lends itself to the new monitoring system, but is not the only technique that would work with it. Excess water draining from the pots is measured and evaluated for quality and levels of wasted nutrients and pesticides. The system has shown that applying water at a slower rate several times a day reduces total water use and has revealed that the trees were being over-fertilized. It also promises to be the safest way to target pesticides, pumping them through hoses to individual spray nozzles attached to stakes in each plant pot.

circulating that warns consumers about purchasing mulch containing wood
debris from Hurricane Katrina. According to Dr. Henderson, if anyone is chipping, bagging and selling mulch from southern Louisiana, it is being done illegally. The same would be true for Texas where there are also large quantities of wood from Hurricane Rita-affected areas that also have Formosan termites. Part of the email message circulating around the Internet
is accurate, at least the part about Formosan termites being found in
damaged trees and the POTENTIAL for Formosans to be transported in wood
mulch. However, the mulching process is highly destructive to termites
and the likelihood is low of transporting a viable mini-colony of Formosans
in this manner. Though there is documentation stating Formosan termites
have been known to be shipped in this manner at least once. The best way to ensure you don’t introduce unwanted
termites into your landscape is to purchase garden mulch from a reliable,
local source. Many municipalities now produce and sell mulches produced
from city yard trimmings and landscape waste. This should be a safe
source for mulch and is a great way to close the circle and encourage
recycling of a valuable resource that would otherwise end up in a landfill. index New NYS Regulations allow Nutrient Claims for Compost For more detailed information please visit: http://cwmi.css.cornell.edu . Source: CWMI Sour Mulch Source: R. Kujawski and D. Swanson, UMass Extension Changes to

of the Earthworms index http://www.news.cornell.edu/stories/Feb06/Swallow-wort.kr.html Pale and black swallow-wort -- twining vines recently classified as invasive species and members of the milkweed family -- have rapidly spread since the mid-1990s. The plants are lethal hosts for monarch butterfly larvae and alter ground cover and affect habitat for grassland birds. And, if that is not enough, the plants are growing with increasing vigor in some maize and soybean fields and are altering forest regeneration patterns.Native populations of pale swallow-wort (Vincetoxicum rossicum) in Ukraine and black swallow-wort (V. nigrum) in southwestern Europe are kept in check, though, by native natural enemies. Natural enemies to plants often include moth caterpillars, beetles, flies and diseases. "They've been here more than 100 years but have exploded in the last 10 to 15 years, and it will still be a minimum of 10 years before we can even release a natural enemy to control their growth," said Antonio DiTommaso, associate professor of weed science at Cornell. "The collaboration between Cornell and the USDA involves studies of the plants' biology to identify weak links in the life cycle that should be targeted, if possible, for biological control," said Lindsey Milbrath, a USDA-ARS research entomologist at Cornell, adding that introducing any agent will require federal approval. "Our research will help guide the selection of an effective agent." Milbrath, whose funding from USDA supports the Cornell collaboration on a three-year project, is working with researchers at a USDA facility in Montpellier, France, and other colleagues who are working in Ukraine and southwestern Europe to identify the plants' natural enemies. The plants contain strong poisons, which likely limit natural enemies. Deer and cattle do not eat them. Researchers also are finding that pale swallow-wort may be replacing milkweeds in open fields in New York state and across the Northeast coast, within the migratory range of monarch butterflies. The monarchs lay their eggs on milkweed, and their larvae eat it as a primary food. Studies have shown that when the monarchs lay their eggs on pale or black swallow-wort, the larvae die within three days. DiTommaso and his graduate students are investigating whether the plants release root chemicals that alter soil conditions. Preliminary findings suggest that communities of mycorrhizae -- soil fungi that help provide more nutrients to plant roots -- differ in species and abundance in areas surrounding swallow-worts. "It could be that swallow-worts release chemicals that make an optimal environment for certain mycorrhizal fungi," said DiTommaso. Through the altered soil, or possibly because of chemicals directly released by the swallow-worts, other plant species have a hard time establishing themselves wherever swallow-worts grow, DiTommaso said. The pink-flowered pale swallow-wort grows rapidly in both
forest understories and in open fields of undisturbed soil throughout
central and upstate New York, around the Great Lakes and in Canada.
The purple-flowered black swallow-wort prefers open areas and have a
foothold in the Hudson Valley, Long Island, southern New York and the
New England coast. New Invasive
