Clemson University researchers are armed with close to $7 million to design protocols for managing invasive guava root-knot nematodes. This nematode is considered to be one of the most damaging in the world because of its wide host range, aggressiveness and ability to overcome the resistance that has been developed against root-knot nematodes in many crops.
Clemson University’s main campus covers some 17,000 acres, but the Tiger paw also adorns dozens of satellite campuses and research centers placed across the entire expanse of South Carolina. One of those orange dots on the map is the Plant and Pest Diagnostic Clinic in Pendleton, which is where you’ll find diagnostician and manager Meg […]
Fig buttercup's bright, shiny yellow petals poke upward from heart-shaped, dark green leaves that carpet several Carolina riverbanks. At the same time, the invasive species also smothers out the native plants that once called the bottomlands home. Surveys conducted by the Department of Plant Industry at Clemson University, a state regulatory agency charged with protecting South Carolina from foreign plant predators, show that colonies of fig buttercup have established themselves along tributaries of the Reedy River in Greenville and the Catawba River in Rock Hill.
Clemson University’s Department of Plant Industry (DPI) has issued updated quarantine information related to two crop pests: sweet potato weevil and Benghal dayflower. The agency expanded a longstanding quarantine due to sweet potato weevils in Charleston and Beaufort counties to include Jasper, Colleton and Berkeley counties. The agency also increased an area of quarantine in Aiken County due to Benghal dayflower. The original quarantine was implemented in November 2016. The area now includes a section forming a triangle from north latitude 33.380, east to U.S. Highway 1, south to U.S. Highway 125 and north back to north latitude 33.380.
A new pest detected in two farm fields in Darlington County has resulted in a quarantine of South Carolina sweet potatoes by Louisiana and Mississippi. Guava root-knot nematode was detected in the Darlington County fields during a routine survey by Clemson University’s Department of Plant Industry (DPI) in September 2017 and confirmed by the U.S. Department of Agriculture in January 2018.
Mosquitoes are breeding in abundance in floodwaters left behind by Hurricane Florence, prompting officials throughout the Pee Dee region to step up pesticide treatments to control them. Experts with the Clemson University Extension Service and Regulatory Services units are advising beekeepers to be aware of increased sprayings and prepare to cover their hives if necessary while sprayings are in progress.
A serious pest of sweet potatoes has been confirmed in three more South Carolina counties by the Clemson University Department of Plant Industry (DPI). The discovery of the sweet potato weevil Cylas formicarius in Jasper, Colleton and Berkeley counties likely means that a quarantine already in place in nearby Charleston and Beaufort counties will be extended to them
Just as the weather warms, they pop their ugly heads out of hiding. But thank goodness they do, because now is the best time to find them so they can be destroyed. The flowers of cogongrass are in bloom now, helping the invasive weed resume its aggressive spread to new fields and forests. Left unchecked, cogongrass will form dense stands over large areas and choke out native plants, doing untold damage to local ecology and to farmers' fields.
Seemingly innocent holiday wreaths sold across the Palmetto State have been found to carry a devastating plant disease. Boxwood blight, a fungal disease that can be deadly to the familiar boxwood shrub, was confirmed on wreaths containing boxwood cuttings from a single North Carolina nursery.
Eight thousand nine hundred and seven samples later, the verdict is in: There's no hint of plum pox in South Carolina. Reaching the conclusion wasn't easy, but the search was essential. Plum pox is the most devastating viral disease of stone fruit in the world — and a potential disaster for South Carolina's important peach business.
CLEMSON – New requirements aimed at reducing pesticide poisoning and injury risks are coming in January 2018 and the Clemson Cooperative Extension Service wants all South Carolina agricultural workers to be prepared. A workshop designed to teach workers how to comply with new requirements coming to the Environmental Protection Agency’s Agricultural Worker Protection Standard (WPS) […]
South Carolina officials have declared a statewide emergency quarantine of some wood products due the Emerald Ash Borer (EAB), an invasive insect pest that inhabits and destroys native ash trees.
The Department of Plant Industry (DPI) at Clemson University will hold a public hearing Friday, Sept. 29, regarding an emergency statewide quarantine for wood and wood products affected by the Emerald Ash Borer (EAB), an invasive insect pest that inhabits and destroys native ash trees.
An invasive Asian beetle responsible for killing hundreds of millions of ash trees in North America has been found in Spartanburg, Greenville and Oconee counties, according to investigators with the Clemson University Department of Plant Industry. This is the first confirmed detection of the beetle known as Emerald Ash Borer in South Carolina.
Clemson University Cooperative Extension is organizing a series of daylong workshops throughout the state to help professional landscapers properly apply weed control and fertilizer.
