(1987). Integrated plant disease management can be defined as a decision-based process involving coordinated use of multiple tactics for optimizing the control of pathogen in an ecologically and economically. In terms of molecular marker the variant of a DNA sequence is referred as an allele. Mostly, molecular alleles are selectively neutral. Transgenic Plant Disease Management ... Molecular Diagnostics of Plant Diseases The first and most important step in managing a plant disease is to correctly identify it. Mapping QTLs is an effective approach for studying plant disease resistance. Molecular alleles should segregate by the same Mendelian principles as phenotypic alleles. Molecular and Biotechnological Approaches in Plant Disease Management 274 Eco-friendly Innovative Approaches in Plant Disease Management methods to increase detection sensitivity. Molecular approaches in plant resistance KARTHIKEYAN, S (2015 800503) Ph.D., Scholar, Agricultural Entomology, TNAU, Coimbatore. 152-155. 9, No. 17.3.3.1 Molecular Marker-Assisted Selection for Developing Nematode-Resistant Plants. Although some diseases can be diagnosed quickly by visual examination, others require laboratory testing for diagnosis. Biotechnology for plant disease control; application of biotechnology to plant pathology. However, to develop homozygous resistant and agronomically superior cultivars, it takes about 6-7 years of rigorous multi locations disease testing at the 'Hot Spots'. Canadian Journal of Plant Pathology: Vol. An allele defined by molecular means should have exactly the same genetic properties as a phenotypically defined allele. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and pesticides. plant diseases is a very economic and easy method of plant disease management. The usefulness of certain measures depends on the specific crop-pathogen combination. 2. 2, pp. Molecular markers are being employed in pathogen detection and characterization. Infectious disease testing: molecular approaches There are many different approaches to the design of molecular diagnostic tests. In many crops, preventative measures can control diseases without the need of plant protection products. This text presents conventional methods involving markers that have been extensively used in the past. Integrated disease management in organic farming combines the use of various measures. Plant diseases need to be controlled to maintain the quality and abundance of food, feed, and fiber produced by growers around the world. disease management? Molecular approaches • Introgression of resistance genes from the wild relatives of crops(=wide hybridization), • Marker assisted selection • Genetic engineering • Gene pyramiding. R. Samiyappan, in Integrated Pest Management, 2014. However, for certain disease problems, It offers a description of genes delivery method in plants, concepts and applications in transgenic research with special reference to diseases resistance.
