\n\t\tKINGSTON, R.I. \u2013 June 5, 2013 \u2013 If it seems that every year you are battling a new pest or disease in your garden, you\u2019re not alone. According to Heather Faubert, who runs the Plant Protection Clinic at the 溏心vlog免费B站, that trend is primarily due to the rapid transportation of plants around the country and the increasing frequency of extreme weather events.<\/p>\n


\n\tTo help local gardeners, landscapers and farmers become aware of what to be on the lookout for in 2013, Faubert has provided this list of the top three plant pests and diseases of the year (along with a few honorable mentions):<\/p>\n


\n\tImpatiens downy mildew: Impatiens are the top-selling annual bedding plant in the U.S. due to their colorful flowers that bloom all summer and their ability to fill in large spaces in the landscape. But this is not the year to plant them — few garden centers even have them available \u2013 due to a fungus called impatiens downy mildew.<\/p>\n


\n\tFirst discovered in a few greenhouses in 2004, it made its way to the landscape in six states in 2011 and arrived in almost every other state in the nation last year. Its spores become windborne, making it easy for it to move from one area to the next. <\/p>\n


\n\u201cEarly symptoms are mottled, down-curled leaves and, later, white spores on the underside of the leaves,\u201d said Faubert. \u201cThen they just die. There may be a few leaves at the top, but the rest of the plant defoliates and dies.\u201d<\/p>\n


\nLittle can be done to protect impatiens from downy mildew, so Faubert suggests gardeners avoid purchasing the plants while the nursery industry searches for a variety that is resistant to the fungus. She says New Guinea impatiens, begonias, and salvias are good alternatives.<\/p>\n


\nCrypt gall wasp: Red and black oak trees with sagging leaves and a thin canopy may be struggling to combat this new invasive insect pest that appeared on Cape Cod last year and has been found in southern Rhode Island. The crypt gall wasp lays its eggs in the new growth of oaks and stunts their further growth.<\/p>\n


\nIn the 1990s, the pests built up a large population on Long Island, but didn\u2019t cause many trees to die, and the wasps declined sharply after about a decade. But landscapers on Cape Cod are concerned the infestation there is severe and many trees will be lost.<\/p>\n


\nFaubert said affected trees can be injected with an insecticide to kill the insects, but it is an expensive process and may not be worthwhile except on particularly treasured trees.<\/p>\n


\nViburnum leaf beetle: This invasive European insect was found in New York in 1996 and was discovered in Warwick, Kingston, Charlestown and Glocester last week. Faubert believes that the viburnum leaf beetle is probably in every community in Rhode Island, where it defoliates the leaves of many species of viburnum shrubs.<\/p>\n


\nThe beetle\u2019s eggs hatch in early May, whereupon they feed on viburnum leaves until early June, and the adults feed on the leaves from July until the first frost. \u201cUnlike most pest insects that feed on a plant either as larva or as an adult, this one feeds on viburnum during both stages, so it could shorten the plant\u2019s life all the more quickly,\u201d Faubert said.<\/p>\n


\nShrubs should not die after one year, but two or three years of defoliation could kill them. So Faubert suggests waiting until the fall or winter when egg masses are easily visible on branches and pruning those branches. An insecticide can also be sprayed on the leaves to kill the insects during the growing season.<\/p>\n


\nIn addition to these pests and diseases, Faubert encourages Rhode Islanders to be watchful for a fungal disease that is killing mature Colorado blue spruce trees; a scale insect whose excrement on oak trees becomes covered in black sooty mold; boxwood blight, a fungal disease that defoliates boxwood trees; and a Japanese fruit fly that lays its eggs in small wild and cultivated berries.<\/p>\n


\nThose seeking diagnosis of plant diseases and pests may deliver or mail samples to the 溏心vlog免费B站 Plant Protection Clinic at the Mallon Outreach Center, 3 East Alumni Ave., Kingston, RI 02881. Insects should be placed in a small container such as a prescription bottle and wrapped to protect it from breakage in the mail. Fresh plant specimens should be placed in a plastic bag and mailed in a padded mailer. Various stages of a plant\u2019s decline should be included (not just dead samples). A $10 fee per specimen must accompany all samples. For additional information, call 401-874-2900.<\/div>\n","protected":false},"excerpt":{"rendered":"
