  Control of Postharvest Anthracnose of Mango Fruits by Luna Sensation and Nativo YE Zi, SU Chulian, SUN Yu, LIU Xiaomei, PU Jinji, ZHANG He, HUANG Hai Journal of Agriculture    2022, 12 (7): 21-25.   DOI: 10.11923/j.issn.2095-4050.cjas2020-0239 Abstract + (671)    HTML (7)    PDF (1275KB) (170)       Knowledge map    In order to explore the methods of controlling postharvest anthracnose by using fungicide in mango flowering and fruiting stage, Luna Sensation and Nativo fungicides were selected to carry out the experiment of postharvest anthracnose control. A total of 6 treatments were designed, including two application dose gradients of each fungicide, a prochloraz test area and a blank test, to compare the disease index among the treatments. The results showed that the fungicides used in this experiment did not harm the young leaves, flowers and young fruits of mango at flowering and fruiting stage, nor did they affect the ripening of mango. 7 days after harvest, the control effect of Luna Sensation sprayed with 1500 times of concentration was equivalent to that of prochloraz, and the control efficiency reached 72.73%, the shelf life could be maintained for 7 days. The control effect of Nativo sprayed with 750 times of concentration was the second, its control of mango anthracnose during the postharvest storage period was effective, and the shelf life and storage period of mango were prolonged obviously. The presence of a new succinate dehydrogenase inhibitor in Luna Sensation, named fluopyram, could work by inhibiting the activity of succinate dehydrogenase. Succinate dehydrogenase inhibitors impede the mitochondrial function by interfering with four subunits of complex II, inhibiting the production of energy and the growth of pathogenic bacteria. The fungicides in this study are consistent with prochloraz in treatment and have a certain value of popularization and application.
