Practice for reducing losses from plant diseases. Infectious diseases may be carried on tomato seed. It is critical to start with disease-free transplants because many Cultural practices are aimed at avoiding disease or delaying cultural practices,ĭisease resistant varieties, and use of chemicals) are integrated into an overall Laboratory for an accurate diagnosis, particularly when a new disease is encountered.Ĭontrol of tomato diseases is best if all available methods (i.e. To submit samples of diseased plants to the OSU Plant Disease and Insect Diagnostic Often, symptoms of diseases are non-typical or confusing.

Thisįact Sheet is intended to aid vegetable producers in recognizing the symptoms of common Such as blossom-end rot, is a wasted expense that will not correct the problem. For example, use of a fungicide to control a non-infectious disease, It is critical for effective disease control to recognize the difference between infectiousĪnd non-infectious diseases, and the type of microorganism causing an infectious diseaseīe determined. The distribution of the disease may be quite uniform and extensive if an entire planting Non-infectious diseases cannot spread from plant to plant however, The second group includes those caused by non-infectious physical or chemicalįactors, such as adverse environmental factors, nutritional or physiological disordersĪnd herbicide injury. These diseases are contagious and can spreadįrom plant to plant in a field, often very rapidly when environmental conditions areįavorable. The first are those caused by infectious microorganisms that includeįungi, bacteria, viruses and nematodes. Diseases are a major limiting factor for tomato production.
