In-vitro RESPONSE OF DIFFERENT FUNGICIDES AGAINST Mauginiella scaettae CAUSING DATE PALM INFLORES...

Inflorescence rot is a highly deadly cryptogamic disease that affects all phoeniculture regions and results in significant economic losses. The identification and characterization of the causative agent is a critical step in combating this disease, but such research is lacking in Morocco. During the years 2020-2021, researchers worked in the Darâa Tafilalet region of south-east Morocco to isolate and identify the fungi that cause date palm inflorescence rot and to try to battle the disease using various fungicides. We gathered 48 infected samples from various date palm kinds. At all of the sites investigated, the isolation results revealed that Mauginiella scaettae is the primary cause of date palm inflorescence rot. We tested seven fungicides (difenoconazole, boscalid-pyraclostrobin combination, thiophanate-methyl, copper oxychloride, tribasic copper sulphate, copper sulphate, copper sulphate, and wettable sulphur) in vitro for antifungal efficacy against M. scaettae. Data on the effects of these fungicides on pathogen mycelial growth, spore germination, and sporulation show that difenoconazole, the Boscalid-Pyraclostrobin combination, and Thiophanate-methyl completely controlled M. scaettae at only 25% of the recommended dose, whereas Copper Oxychloride, Tribasic Copper Sulfate, and Copper Sulfate all had a significant inhibitory effect on all The least effective was wettable sulphur.
