Last year, the TVA found water hyacinth in a slough near Scottsboro. TVA quickly partnered with the State of Alabama, bringing experts from both sides to start addressing the invasive water weed. Water hyacinth is bad news for Guntersville and other great fisheries in the Tennessee Valley. The plant can quickly outcompete other beneficial plants, often creating biological wastelands. Hartis and his team are asking the public to be on the lookout for hyacinth this summer. “If you see a [hyacinth] plant, pull it out of the water immediately and put it in the trash. We don’t want plants to float to a new area and establish a new colony.” If you find a large area of hyacinth, please report it to TVA's Public Land Information Center at (800) 882-5263 (between 8 a.m. and 6 p.m. Eastern).

This concise publication gives useful information for homeowners, master gardeners, and professional landscapers about the boxwood blight disease: its symptoms, sanitation measures when it is discovered on a property, and preventive measures.
New Hampshire Department of Agriculture, Markets, and Food.
Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.

A plant disease that presents a serious threat to the U.S. citrus industry has been detected in Alabama. Federal and state plant health officials have confirmed the identification of citrus greening (CG), also known as Huanglongbing or HLB, which is caused by the bacterial pathogen Candidatus Liberibacter asiaticus. This is the first confirmation of citrus greening in Alabama despite biannual surveys for the pathogen by the Alabama Department of Agriculture and Industries (ADAI).

Emerald Ash Borer (EAB) was found in Boulder, CO, in September 2013. As a non-native insect, EAB lacks predators to keep it in check. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). EAB is responsible for the death of millions of ash trees in the Midwest. Help protect Colorado's ash trees! Don't move firewood, and consider chemical treatments to protect high-value ash trees.

South Dakota Department of Agriculture.

The South Dakota Department of Agriculture (SDDA) has confirmed that an infestation of emerald ash borer (EAB) has been discovered in northern Sioux Falls. This is the first confirmed infestation in South Dakota. Emerald ash borer is an invasive insect that has killed tens of millions of ash trees in at least 32 states. On May 9, 2018, Secretary Mike Jaspers implemented an Emergency Plant Pest Quarantine in order to prevent or reduce the spread of the EAB. This emergency quarantine is effective immediately. For more information, see the Emerald Ash Borer in South Dakota website.
