The UNL Plant and Pest Diagnostic Clinic in Lincoln offers crop-related services in the following areas:

Plant Pathology — Services for any type of plant, including field crops, turfgrass, fruits, ornamentals, trees, vegetables and others. Diseases are caused by biotic or living agents such as bacteria, fungi, nematodes, and viruses. Diseases are also caused by abiotic, or non-living factors such as nutrient deficiencies, temperature stress, water stress or a combination of several of these factors.

Entomology — Identification and information on insects, mites, spiders, and other related arthropods. Samples may be submitted from a variety of indoor and outdoor sources, including field and horticulture crops, ornamentals, structural and aquatic environments, as well as human, livestock and pets.

Agronomy (Weed Science) — Dependable diagnostic information for weed identification and herbicide injury. Herbicide injury is determined solely on a visual inspection of the plant sample provided; no chemical analysis is performed. Chemical and cultural control practices accompany weed identifications. In addition, information can be provided on herbicide use and symptoms of herbicide injury.
