Fungus

Our cherry tree was oozing sap all over and had dark dead patches on the trunk and branches. The tree service said it had a fungal root rot and we had to cut it down. Can we plant another fruit tree or a vegetable garden when that fungus is in the soil? Will it sicken us? Your tree's disease symptoms match leucostoma canker, also known as cytospora, which is not a soil fungus and doesn't affect humans. Replant with confidence. In the future, take precautions to prevent a stone fruit (cherry, peach, apricot)

My friend offered me extra plants from her yard. She said they are pretty but spread a lot. I'm a little nervous about accepting them. What do you think? Beware pass-along plants when a friend says they are indestructible, spread fast, and outcompete other plants. If you hear "Nothing kills it!" that can be a recipe for disaster. (When the plant is not native, it's a perfect description of an invasive plant.) You don't want to be fighting these plants for years to come. Many plants will spread or reproduce in the landscape when they are happy — and that's great — yet most do not get out of control.

Biologists have found what they believe is the first evidence that Maryland bats are now infected with white nose syndrome, a deadly fungal disease that has killed more than a million hibernating bats since 2006, devastating colonies from New England to Virginia. A state biologist conducting a bat survey Friday found dead and weakened bats in a cave on private property near Cumberland, the Department of Natural Resources reported Wednesday. About three-quarters of the winged mammals had the telltale white fungus on their muzzles and other exposed skin.

Q.Thank you for printing the vinegar treatment for foot fungus. My husband has had so-called jungle rot since his days as a soldier in Vietnam. It's been incurable, but now it is all but gone, with only a few soaks needed every so often to keep it from coming back. My father, an eye doctor, told an elderly patient about vinegar. She was about to have a toenail amputated by another doctor because the fungus could not be cured. She started soaking her foot and saved her toenail. A.Dermatologists groan when we write about home remedies for nail fungus.

Q. My mulched beds have small brightly colored mounds of what looks like a fungus growing on them, but they are dry. Is it a fungus and will it harm my plants? A. The odd looking organism you have discovered is a plasmodium and not a fungus. It lives on decaying organic matter, such as mulch. This type of plasmodium is relatively common and though it looks unsightly, it will not harm your plants. Because it does no harm to plants, I would suggest that you simply turn it into the mulch with a shovel.

Our old red maple fell in a storm. When we had it removed, we were told it had root fungus and we should not plant a replacement tree on the same spot. I planned to replace this tree with a tulip poplar. How close to the original spot can I safely plant a sapling? Because you are planting a different species, you can plant in the same spot, but do move the plant a few feet away from the ground-up stump. Chips from the stump mix with the soil and bind up nitrogen as they decompose. Your new tree will need soil nitrogen for growth.

It practically killed off the elm tree, caused the Irish potato famine and has been labeled the world's largest living organism.Fungus -- a life form that attacks athletes' feet and sprouts as mushrooms -- is nowhere more abundant than in the National Fungus Collections stored at Beltsville Agricultural Research Center.The collections, put together and owned jointly by the U.S. Agricultural Research Service and the Smithsonian Institution, make up the largest storehouse of fungus in the world, serving as a repository for about 1 million specimens of mushrooms, toadstools and other organisms plucked by government and private scientists over the past century.

PHILADELPHIA -- They toiled in labs for nearly a century and spent inestimable millions. They tested an arsenal of pesticides, parasites, predators and viruses. But the best brains in bug science couldn't produce the silver bullet that would bring down the gypsy moth.Through it all, the voracious insect chewed its way across the Northeast, stripping vast swaths of forest.Now, faster than you can say "Mother Nature," researchers appear to have found the solution growing right under their noses.

An Eastern Shore legislator held a news conference yesterday to call attention to a scientific study that questions whether the lesions found on dying fish on the lower Eastern Shore in 1997 were primarily caused by blooms of the toxic microbe Pfiesteria piscicida or by a fungus now attacking fish in the Eastern Pacific.A team led by Vicky S. Blazer of the U.S. Geological Survey argues in a paper scheduled for publication that the deep, bloody sores on schools of menhaden were triggered by infection with a fungus called Aphanomyces.

My grass has tiny orange raised bumps on the blades. It started about the beginning of fall. It seems worst where there is more shade and the ground stays moist longer. Will it kill the grass? Numerous blades are completely covered. I fertilize a few times a year, using the recommended amount for my bluegrass. Kentucky bluegrass and perennial ryegrass are the grasses most susceptible to rust, a fungal disease. Rust disease is favored by low nitrogen fertility, but this is probably not your cause.

White nose syndrome, a fungus deadly to hibernating bats, has been identified in an abandoned mine complex in Washington County. It is the second place in Maryland where hibernating bats have been found to be infected. "Hibernacula surveys are still underway," said Dan Feller, a biologist with the Maryland Department of Natural Resources. Affected bats have been found in four of the 10 mines in the Washington County complex, which is considered a single site. "We have adjacent counties in both West Virginia and Pennsylvania that are affected, so we knew we would have additional sites this year," he said.

Working for a decade, almost entirely out of public view, staffers at the Maryland Zoo in Baltimore have made the institution the nation's largest breeder and shipper of the endangered Panamanian golden frog. On Tuesday, 25 of the tiny, yellow-and-black amphibians were packed with wet paper towels in 13 pint-sized deli cups. The cups were set into a comfy nest of crumpled newspapers inside a Styrofoam box labeled "Live Amphibians!" The frogs were then driven to BWI-Marshall Airport for a 10-hour trip to the Fort Worth Zoo, in two hops on Delta Airlines jets.

Cool, wet summer promotes fungus growth Maryland agriculture officials say the cool, wet summer is leaving the state's grain crops vulnerable to fungus damage. Agriculture Department spokeswoman Sue DuPont says farmers noticed a problem with the crops about a month ago. The University of Maryland agriculture extension office says the state chemist's office has been distributing test kits to farmers across Maryland. Testing has found increased levels of a fungus known as vomitoxin across the state with the bulk reported in Southern Maryland.

Maryland farmers are on the lookout for a contagious fungal disease that could devastate future harvests across the state. The disease, called soybean rust, or Asian soybean rust, has been steadily creeping toward Maryland from the Deep South since it was discovered in Louisiana a little more than a year ago. In other parts of the world, including southern Africa and South America, it has reduced soybean yields by as much as 80 percent when left untreated....

A devastating fungus is sweeping the planet, wiping out entire populations of amphibians at such a rate that biologists are helping pull together a huge "Noah's Ark" project to capture frogs, toads and salamanders and put them in safe places. Various factors already have combined to cause more than 120 amphibian species to vanish since 1980, in what one biologist has called "one of the largest extinction spasms for vertebrates in history." A third of the world's nearly 6,000 amphibian species are threatened - their populations weak and susceptible to disease.

White-nose syndrome, a deadly fungal infection that has devastated bat populations in New York and New England in the past two years, has now spread to three states on Maryland's borders - and seems poised to strike here next, biologists say. "We are surrounded on all sides," said Aimee Haskew, a faculty research assistant at the University of Maryland's Appalachian Lab in Frostburg. "It's like a guillotine hanging above your neck." An outbreak here could destroy one of the largest hibernating populations surviving in the East of the globally rare Eastern small-footed myotis and gradually wipe out larger bat populations that help to control Maryland's insect pests.

When I needed treatment for toenail fungus, my doctor suggested I soak my toes in Listerine for 30 minutes a night for 30 days. I sent my husband to Costco for a giant jug of Listerine. He returned with the mint one. It's blue, but I figured that wouldn't really make a difference. It did. My feet turned blue, and no amount of scrubbing could take the color off. After switching to the regular (amber) Listerine, my toenail fungus did clear up, but the nails themselves were very dry. The herbal oils in Listerine, such as thymol and eucalyptol, have antifungal activity.
