Abstract:

Peanut leaf spot disease is a major disease severely restricting the healthy development of the peanut industry in China, and its effective prevention and control is crucial for the sustainable development of the industry. This paper systematically elaborated on the symptomatic characteristics of various leaf spot diseases, including Cercospora arachidicola, Cercosporium personatuma, Phoma arachidicola, and Leptosphaerulina crassiasca, caused by different pathogens. It introduced the disease-promoting conditions from aspects such as continuous mono-cropping, temperature and humidity conditions, and variety resistance. Furthermore, the occurrence patterns of peanut leaf spot disease were analyzed based on factors including the pathogenic conditions, the infection process, and the disease cycle. Based on the infection process and field epidemiology, the comprehensive prevention and control strategy of peanut leaf spot disease was expounded. Main agricultural prevention and control measures of peanut leaf spot disease were introduced from the aspects of removing diseased residues, reasonable rotation, strengthening field management, and selecting disease-resistant varieties; the main research progress of peanut leaf spot disease in the field of biological control was expounded from the aspects of the competitive mechanism of biological control bacteria, antimicrobial metabolites and induced resistance; the main research progress of peanut leaf spot disease in the field of chemical control was introduced from the aspects of the high efficiency and safety of chemical agents. The principles of reducing dosage and increasing efficiency, precise rotation, and green agent types were proposed. We believe that the prevention and control of peanut leaf spot disease should adhere to the basis of agricultural control, combined with biological control and chemical control, and establish a comprehensive technical model to ensure the sustainable development of China's peanut industry.

Key words: peanut leaf spot diseases, pathogenic fungi, epidemic regulation, comprehensive prevention and control, disease-resistant breeding, research progress
