The collection of digital images is provided as a service to Arkansas agriculture. These images represent symptoms of both pathological (infectious) and non-pathological (physiological/environmental) disorders of agronomic row crops and horticultural crops that grow in Arkansas. These photos are useful as an identification tool to growers of the crops listed.

To address mounting concerns over invasive plants and the role NHDOT activities play in the spread of these plants along roadsides, Best Management Practices (BMPs) have been developed with input from Maintenance Districts, the Roadside Development Section, the Bureau of Construction, and the NH Department of Agriculture. Implementation of these BMPs will help prevent the spread of invasive plants caused by maintenance and construction activities.

Quagga mussel larvae, or veligers, were first confirmed in Lake Powell in late 2012 after routine water monitoring tests discovered mussel DNA in water samples taken from the vicinity of Antelope Point and the Glen Canyon Dam. As of early 2016, thousands of adult quagga mussels have been found in Lake Powell, attached to canyon walls, the Glen Canyon Dam, boats, and other underwater structures, especially in the southern portions of the lake. It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures.
