Abstract:
Plant pathology is the study of plant diseases and provides farmers with advice on how to control those diseases. It improves disease management strategies to ensure global food security and safety. The combined effects of illnesses, insects, and weeds are predicted to prevent the production of all crops grown worldwide each year. The losses are typically higher in developing nations, or nations with the greatest food needs, and lower in more developed nations. According to estimates, diseases account for 13.7% of the 35% average total losses, insects for 11.3%, and weeds for 13.5%. The basic concepts of plant pathology are generalizations that apply to a wide range of plant diseases that have certain fundamental things in common, such the fact that they are all brought on by microbes. The severe variances between pathogens, such as those between fungi and viruses, frequently necessitate some modification of the principles, though. The enormous variety of occurrences that precede plant diseases is still unified by some true statements provided by the principles of plant pathology. In addition, there are areas with a lot of variation, such as internal transcribed spacer regions. For any fungus, oomycetes, or bacteria, the conserved areas can be utilized to construct universal primers for the group detection of microorganisms within a taxon, while the existence of variable regions enables the identification of differences between races, strains, and isolates. Beta-tubulin genes, which are linked to fungicide resistance, are another set of target sequences employed for the detection of fungi. The target fragments are typically derived from pathogenicity-associated genes and bacterial plasmid DNAs. Fungi that cause disease get their energy from the plants they feed on. They cause a lot of harm and are distinguished by wilting, scabs, mouldy coats, rusts, and blotches, as well as rotten tissue.
