“…Chemical control has not been effective and long lasting, even though in vitro screening has identified several chemicals that are effective against Ganoderma (Hashim, 1990;Teh, 1996). Numerous studies attempting to control BSR in the field by the use of systemic fungicides have been unsuccessful (Loh, 1976;Jollands, 1983). The effective use of chemical control for treatment of Ganoderma-infected palms is limited by the fact that both visibly infected and subclinical palms may harbour established infections by the time treatment is applied.…”

This chapter presents the results of a study on the effects of calcium nitrate as a prophylactic measure against basal stem rot (BSR; Ganoderma) on oil palm seedlings. Treatments comprised: 5.0 or 7.5 g CaNO3/seedling starting at either one month before inoculation or one day after inoculation, control, and 60-g preparation of Trichoderma applied one day after inoculation. Calcium nitrate applications were continued at monthly intervals over a period of 6 months, while the antagonistic fungus was applied only once. The BSR incidence in pot-grown oil palms was suppressed significantly upon treatment with calcium nitrate one month prior to inoculation. Soil augmentation with Trichoderma one day after inoculation did not control the BSR incidence significantly. The role of calcium in reducing BSR incidence is hypothesized as that of stabilizing and strengthening the cell walls of the oil palm seedlings and stimulating the proliferation of antagonistic fungi that will compete for space and nutrients.

“…The use of systemic fungicides, combined with an appropriate technique, may provide an effective solution against disease-causing pathogens. In vitro screening of several fungicidessuch as cycloheximide and drazoxolon (Ramasamy 1972 ); benomyl, bilaxazol, triadimefon, triadimenol, caroboxin, carbendazim, methfuroxam, and cycloheximide (Jollands 1983 ); cyproconazole, hexaconazole, and triadimenol (Khairudin 1990 ); penconazole, triadimenol, and tridemorph (Lim et al 1990 )-has shown strong inhibitory action against Ganoderma . Turner ( 1981 ) reported that organic mercury formulations have proven effective against Ganoderma under fi eld conditions but became unacceptable for commercial use because of the residues it left.…”

“…Turner ( 1981 ) reported that organic mercury formulations have proven effective against Ganoderma under fi eld conditions but became unacceptable for commercial use because of the residues it left. Attempts have been made to control BSR in fi eld conditions using systemic fungicides through trunk injection, soil drenching, or combinations of both and utilizing pressure injection apparatus (Jollands 1983 ;Khairudin 1990 ). These techniques showed promising results for the suppression of Ganoderma infection in fi elds where the systemic fungicide bromoconazole was used (Ariffi n and Idris 1997 ).…”

“…The usual method of controlling BSR in oil palm plantations is the use of chemical fungicides. Many fungicides, such as azoxystrobin, benomyl, carbendazim, carboxin, cycloheximide, cyproconazole, drazoxolone, hexaconazole, methfuroxam, nystatin, penconazole, thiram, triadimefon, triadimenol, tridemorph, and quintozene, could inhibit the growth of Ganoderma [6][7][8][9][10]. However, the fungicides cannot actually cure infected palm trees; they can only delay the spreading of the disease [9].…”

New Antimicrobial Phenyl Alkenoic Acids Isolated from an Oil Palm Rhizosphere-Associated Actinomycete, Streptomyces palmae CMU-AB204T

Basal stem rot (BSR), or Ganoderma rot disease, is the most serious disease associated with the oil palm plant of Southeast Asian countries. A basidiomycetous fungus, Ganoderma boninense, is the causative microbe of this disease. To control BSR in oil palm plantations, biological control agents are gaining attention as a major alternative to chemical fungicides. In the course of searching for effective actinomycetes as potential biological control agents for BSR, Streptomyces palmae CMU-AB204T was isolated from oil palm rhizosphere soil collected on the campus of Chiang Mai University. The culture broth of this strain showed significant antimicrobial activities against several bacteria and phytopathogenic fungi including G. boninense. Antifungal and antibacterial compounds were isolated by antimicrobial activity-guided purification using chromatographic methods. Their structures were elucidated by spectroscopic techniques, including Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS), Ultraviolet (UV), and Infrared (IR) analyses. The current study isolated new phenyl alkenoic acids 1–6 and three known compounds, anguinomycin A (7), leptomycin A (8), and actinopyrone A (9) as antimicrobial agents. Compounds 1 and 2 displayed broad antifungal activity, though they did not show antibacterial activity. Compounds 3 and 4 revealed a strong antibacterial activity against both Gram-positive and Gram-negative bacteria including the phytopathogenic strain Xanthomonas campestris pv. oryzae. Compounds 7–9 displayed antifungal activity against Ganoderma. Thus, the antifungal compounds obtained in this study may play a role in protecting oil palm plants from Ganoderma infection with the strain S. palmae CMU-AB204T.
