Current Status of Grain Discoloration Disease of Rice In Pakistan And Its Management

Rice is an essential export and a staple food in Pakistan, but it also meets numerous challenges from diseases, such as rice grain discoloration, which is made worse by climate change. This situation challenges economic stability by affecting yield and quality due to a variety of biotic and abiotic causes. Temperature fluctuations, extreme humidity, and microbial diseases are all linked to discoloration. Effective management techniques have been investigated, emphasizing the contribution of silicon to improving plant resistance. These techniques include cultural practices, biological control, and chemical treatments. Inducing physiological changes and functioning as a mechanical barrier, silicon reduces the severity of disease. Additionally, the development of disease-resistant rice varieties is made possible by developments in molecular breeding and biotechnology, such as marker-assisted selection. The comprehensive review emphasizes the necessity of ongoing studies to lessen the effects of grain discoloration and enhance Pakistani rice production.
