1 Integrated Vegetable Disease anagement Successful management of vegetable diseases requires a disease management program that integrates the use of resistant varieties, balanced soil fertility, irrigation water management, use of good cultural practices, weed and insect control, biocontrol, and chemical control. Development and implementation of a disease management plan and good record keeping will increase the overall yield and success of the vegetable crop. Start with clean seed and/or certified disease-free transplants. any vegetable disease problems originate with the seed or transplants. Seed should be purchased from reputable commercial seed companies and if seed has not been previously treated it should be treated following the seed treatment recommendations provided in Section IV. Select resistant varieties. The use of resistant varieties is one of the best management strategies in an integrated pest management program as they are inexpensive compared to the cost of fungicides and bactericides and they provide seasonal management. Select resistant varieties based on the disease profile for your production region and soil. Use good cultural practices. Cultural practices are defined as a broad set of techniques that are used to manipulate the environment to improve crop production. Examples of cultural practices that should be considered in an integrated disease management plan are provided below. Select land suitable for vegetable production. Start by selecting a site that is well drained, has good air movement, gets at least 6 hours of sunlight each day, and does not have a history of problems with soilborne diseases. Avoid land surrounded by large established trees. Tree roots that extend well beyond the extent of the limbs can exhaust water and nutrient resources that would otherwise be available to the vegetable crop. Some tree roots also produce a toxin (juglone) that causes toxicity in toxin-sensitive vegetables such as tomatoes, peppers, eggplant, potatoes, asparagus, cabbage and broccoli. Have your soil tested. any pathogens that cause disease on plants live and survive for long periods of time in the soil. Soil temperature, moisture, ph and fertility all influence a pathogens ability to survive and colonize plants. Have your soil tested annually to determine the ph, salts, nutrients and organic matter levels, and water holding capacity. For more information on how to sample, test and assess the quality of your soil contact the LSU AgCenter Soil Testing & Plant Analysis Laboratory. Tests are also available that can determine the population levels of some pathogens in the soil. Contact the LSU AgCenter Plant Disease Diagnostic Center for more information on available pathogen tests.

2 Use high quality water for irrigation and other agricultural uses. Untreated surface waters can harbor both plant and human pathogens. If practical, and economical, potable water should be used to irrigate vegetable crops, especially when crops are irrigated using overhead (sprinkler) irrigation systems. Water treatment and filtration practices should be adopted if surface water is the primary source of irrigation water. The timing and frequency of irrigation should also be considered to minimize the risk of disease development. Avoid overwatering and overhead irrigation. Water early in the day so that plants have an adequate amount of time to dry. Consider raised beds to reduce the amount of standing water in the rows. Develop a four-year crop rotation cycle. Crop rotations are an important component of an IP program because they interrupt the life cycle of pathogens by placing the pathogens in a nonhost environment. Through this interruption the pathogens are unable to accumulate to levels that could cause significant levels of disease and crop losses. Over a four-year period plant plants from a different plant family. Use plastic and organic mulch. ulch serves as a barrier between the soil and plant tissue and reduces the amount of pathogen that can be splashed onto leaves, stems and fruit. Lightreflective plastic mulches can deter insects that transmit important viral diseases from landing on plants. Do not reuse plastic mulches. Organic mulches help to retain moisture in the soil and improve soil quality. Use good sanitation practices. By putting a strong emphasis on sanitation practices disease development can be significantly reduced resulting in less disease and ultimately less chemical usage. A good sanitation practice is any technique that eliminates a desirable place for the pathogen to survive and spread. Removal and destruction of crop debris, weeds and infected plants, and cleaning and disinfection of production tools and equipment are examples of good sanitation practices. Use registered biorational products. Biorational products (products composed of beneficial microorganisms or their products) are viable alternatives to synthetic chemicals for managing diseases in many vegetable production systems. As with chemical pesticides, biorational products can t be used if they are not registered with the Environmental Protection Agency (EPA). Always read the label and follow all safety precautions provided in the label. Do not use biorationals on a non-labeled crop. A list of biopesticides and fungicide alternatives for vegetables is provided in Table 6. Use registered chemicals. Fungicides, bactericides, and nematicides are important tools for managing diseases and their efficacy and efficiency can be enhanced when incorporated into an integrated disease management program. Pesticides should be used in a manner that minimizes the risk of a pathogen becoming resistant to a pesticide. Always applying mixtures of pesticides or alternate fungicides that have different modes of action to help reduce pesticide resistance development by the pathogen. ore information on pesticide resistance management strategies is provided in Section I-D of this guide. A list of fungicide mode of actions for fungicide resistance management in vegetables is provided in Table. Always read the label and follow all safety precautions provided in the label. Do not use pesticides on a nonlabeled crop. A list of selected pesticides with known efficacy to various pathogens that can cause disease on vegetables in Louisiana can be found in Table.
