Plant Pathology & Crop Physiology

The Department of Plant Pathology and Crop Physiology is recognized nationally and internationally for applied and basic research on economically important agricultural crops. Climactic conditions in Louisiana allow cultivation of and research on semitropical crop species such as rice, sugarcane, cotton, sweet potatoes, and soybeans. Through our extension services, we conduct research and assist Louisiana farmers in the management and control of plant disease.

Our graduate program presents students the opportunity to work with Louisiana Agricultural Experiment Station personnel who conduct investigations in areas of plant pathology, crop physiology and plant molecular biology. M.S. and Ph.D. graduates of the department are prepared for challenging careers in agricultural research at universities, governmental and private agencies.

County Extension Agent Training 2008

The LSU AgCenter extension personnel associated with the Plant Disease Diagnostic Clinic and the Nematode Advisory Service conducted a 2-day training session for county extension agents on August 19-20, 2008. Twenty-one county agents attended the training session, which, focused on various aspects of plant disease diagnosis.Dr. Lawrence Datnoff, head of the Department of Plant Pathology & Crop Physiology, and Dr. Bobby Fletcher, Jr., Assistant Director of the Louisiana Cooperative Extension

Mole Crickets

Mole crickets cause millions of dollars in turf and grass damage each year. Their burrowing in the soil breaks up the soil and causes roots to dry out. Identification, life cycle and control included.

How To Submit A Sample

Collecting material for disease diagnostic identification.

Submitting a proper sample with as much information as possible is extremely important in diagnosing disease. Collected sample should be mailed immediately to prevent drying and development of secondary pathogens.

Nematode Management in Louisiana Sweet Potato Production

Plant-parasitic nematodes can damage plants in many ways and are considered to be a serious threat to sweet potato production in Louisiana. This publication describes problematic nematode species and management strategies available for these pests.

Louisiana Plant Pathology: Southern Root-knot Nematode on Vegetables

The southern root-knot nematode (Meloidogyne incognita) is a widespread problem in Louisiana. This pest favors the soils where most vegetables are produced and has been found in about 25 percent of the vegetable gardens in our state. This nematode can be extremely damaging to some crops and causes severe losses. (PDF Format Only)
