Abstract:

Mango Sudden Death Syndrome (MSDS) reported from Brazil, Oman and Pakistan has gained much importance in Pakistan. A lot of research has been done on fungi associated with MSDS but the role of nematodes has been sparsely studied. This particular study was done to observe the trend of Mango Sudden Death Syndrome (MSDS) in relation to fungal microflora and nematodes fauna in selected four districts of Punjab, Pakistan. It was observed that the maximum disease incidence 28% and severity rating 4 (31-50%) was recorded in Multan where combination of different fungi was present and thus there was an increased population of fungal eater nematodes. Following Multan disease incidence (20%) was found in Bahawalpur, Faisalabad (18%) and Jhang (10%) with disease severity 3 (21-30%), 2 (11-20%) and 1 (1-10%), respectively. It is very interesting to note that the disease incidence and severity has similar trend and are directly proportional to each other in the observed locations. The fungus Ceratocystis fimbriata alone as well as in combination contribute towards the disease incidence as in Multan and Bahawalpur. However fungi such as Fusarium solani and Nattrassia mangiferae seem to contribute much low towards the disease incidence. Nematodes such as Xiphinema sp., Hoplolaimus sp., Longidorus sp. and Hemicriconemoides sp. are present in combinations at every location wherever there are fungi in combination. This study opens the way forward that why nematodes population are higher where there is high fungal frequency! Do they contribute towards the disease development or they try to feed on fungal population and act as natural enemies.
