Brown root rot disease is a major constraint on cashew plantation in Pekat District, West Nusa Tenggara. Its causal agent has not been characterized. This paper describes efforts to study the pathogen, distribution and loss. Field study was conducted in Pekat District in 2003. Laboratory  experiments to isolate and test the causal agent were conducted in the Indonesian Spices and Medicinal Crops Research Institute, Bogor.  Research results showed that the disease was found widespread in several villages in Pekat District, such as Pekat, Beringin Jaya, Sorinomo, and Nangamiro. Total number of died cashew trees was 1,075 equals to 5,106 kg kernel yield lost, worth Rp20.5 million. Infected trees showed leaf yellowing and defoliation leading to die. The lateral and taproots near collar were encrusted with gravel, earth, and brown mycelia sleeves. The fungus produced arthrospores and brown pigmentation on agar medium containing 0.05% gallic acid. An isolate of the fungus induced typical disease symptoms following inoculation on 5 month-old cashew seedlings. These results indicated that the causal agent of mass decline of cashew in Pekat District is Phellinus noxius. In field, the fungus also infects a barrier tree (Lannea coromandelica [Houtt.] Merr.) (Anacardiaceae), locally known as kedondong pagar or kayu bantenan.

Biological Effectiveness

Chickpea (Cicer arietinum L.) production is constantly compromised by a complex of pathogens which cause wilt and root rot (WRR). Therefore, biological control and organic products have regained great importance in the last few years. In this work, polyphenols were obtained from ethanolic extracts through the ultrasound-microwave assisted technique from the plant species chinese privet leaves (Ligustrum lucidum) and moringa leaves (Moringa oleifera). A qualitative analysis through reverse phase high-performance liquid chromatography electrospray ionization mass spectrometry (RP-HPLC-ESI-MS) was conducted, so that their biological effectiveness under greenhouse conditions was determined by each group of polyphenols against Fusarium oxysporum f. sp. ciceris, Fusarium solani, and Macrophomina phaseolina which comprise the wilt and root rot complex. A complete randomized block design was established with three blocks and five treatments with nine replications each. Treatments were: Polyphenols of Ligustrum lucidum, polyphenols of Moringa oleifera, the fungicide Benomyl, the inoculated check, and the untreated check. The analysis of variance was performed and mean comparison with Duncan`s multiple range test (0.05). The results indicate that all groups of polyphenol had in their chemical composition, some compounds of known microbial activity, such as hydroxycinnamic acid, flavones, anthocyanins, catechins, and alkyphenols. Under greenhouse conditions, plants that had the lowest incidence and severity of the disease, were those treated with polyphenols from L. lucidum with 66% incidence, and were statistically different to the rest of the treatments.

Wild Solanum

Five wild Solanum species were screened against dry root rot disease in glass house condition with commonly cultivated brinjal as control. The disease was scored at different day’s interval on 30th, 45th and 60th days after planting (DAP). Among the wild species screened and evaluated the species S. torvum was observed without any disease incidence i.e (0). The least per cent of disease incidence was observed in S. incanum (38.60%) which was followed by S. xanthocarpum (42.80%), S. viarum (64.20%) and CO2 (78.50 %) susceptible check at 30 DAP. Secondary metabolites were analysed from both wild and control plants. Based on the per cent disease incidence values S. torvum was graded as ‘Resistant’ against M. phaseolina and can be recommended as a best rootstock for brinjal under varying climatic condition especially where the dry climate prevails.
