A wide range of organisms are involved in crown rot of bananas but Colletotrichum musae is frequently considered as the most commonly isolated fungus and the most pathogenic one. tree, a section was made where the pith was found to be loose, moist, and rotted. fungicides. The disease progressed rapidly, along the stems in the following week and symptoms often were. The respective anamorphs for Ce. Aust. You can download the paper by clicking the button above. Symptoms associated with. Damage area around the point of in-, oculation of the cuttings and whole plants of the tested cultivar, increased progressively with time, reaching a peak DSI value within, 4 and 8 wpi, respectively. Mbenoun, M., de Beer, Z. W., Wingfield, M. J., Wingfield, B. D., and Roux, J. All experiments were repeated three times with. significant differences among tested tissues for Chichi. m for aleuroconidia and phialoconidia, respectively. The data, . 2005). Chemical control of plant diseases is not environmentally safe and the residues of fungicides are a threat to nature. These sequences are: AF275492, HM462018, AF043599, and KF953932), Mean character distances were used to construct the neighbor-, joining phylogeny (Saitou and Nei 1987) using software MEGA, V6.0 (Tamura et al. Stats. The leaves are feather-like with spiny petioles and thick midrib. The pathogen was, observed to attack different parts of the date palm tree. A. Similarly, the ITS (KJ410228) which. Early infections can. Black scorch and leaf basal rot are low spread. The antagonistic activity of S. globosus against T. punctulata, was associated with the production by this strain of diffusible antifungal metabolites i.e., metabolites that can inhibit mycelial growth of the pathogen. Lack of, or excess irrigation, just as soil salinityabove 6%, are all factors that can endanger the health of the tree. Singleton, L. L., Mihail, J. D., and Rush, C. M. 1992. Palm diseases are among the major factors affecting its growth and productivity. Score, Phyton, and Naturame were e, tion of the fungus at the tested concentration (250 ppm), whereas Ortiva, was not (Fig. J. Saudi J. Biol. Phylogenetic trees, were constructed and validated with a statistical support of the. This is the first report confirming that the chemical fungicide Cidely ® Top is strongly effective against SDS on date palm. 1D). Back to the pathogens species list. Protection of pruning wounds using fungicides is the prevalent strategy to management of the diseases caused by L. theobromae . Results from the volatile metabolic assay and SEM suggested potential roles of cell wall degradation enzymes and volatile substances produced by T. harzianum as two collective mechanisms leading to degrade the cell wall of the pathogen and inhibit fungal growth. Zaid, A., and de Wet, P. F. 1999. Thielaviopsis paradoxa and T. punctulata have been recorded as causal agents of black scorch or neck bending on date palm (Khairi et al. This fungus, which was consistently isolated on potato dextrose agar from infected tissues, produced two types of conidia: the thick-walled aleuroconidia (chlamydospores) and phialoconidia (endoconidia). The nucleotide sequence and phylogenetic analyses using the 16S ribosomal RNA gene with other Streptomyces spp. Chalara ovoidea, Ch. IDM is a program that may use a combination of antagonists, such as fungicides, bioagents, and plant extracts to prevent pathogen, have focused on biological controls using, Soytong et al. Jan. 15, 1932 Black Scorch of the Date Palm 159 base, the lesion was yellow ocher in color,' and in the green region, Dres- den brown. eucalypti, which lack aleurioconidia, are also transferred to the amended genus Thielaviopsis as T. ungeri, T. quercina, and T. eucalypti. This disease has been observed in, various date-growing areas in the world. Ceratocystis radicicola (anamorph: Thielaviopsis paradoxa) was reported as an economically important pathogen causing serious diseases on date palm such as rhizosis (2) and black scorch (3) or as an associated pathogen with diseased date palm (1). Because the use of biocontrol agents (BCAs) can minimize the impact of pathogen control, A study was conducted to investigate the genetic diversity of C. radicicola from different regions of Oman and its relationship to populations of C. radicicola from other parts in the Arabian peninsula and the USA. use with the PCR to amplify conserved genes from filamentous Ascomycetes. Black scorch and sudden decline syndrome (SDS; also known as Fusarium wilt) are among the devastating diseases of date palm. Physiological, studies and chemical control of black scorch disease of date palm caused by, Paulin, A. E., and Harrington, T. C. 2000. Streptomyces globosus UAE1, a Potential Effective Biocontrol Agent for Black Scorch Disease in Date Palm Plantations. Kuwait Journal of Science and Engineering 28, 161-170. S4). Important variations of both the severity of the damage and the nature of the complex are observed, depending on various pre- and postharvest factors. f. sp. First Report of Thielaviopsis punctulata Causing Black Scorch Disease on Date Palm in Qatar عرض المنشور . 2013) and F. proliferatum associated with date bunch fading in Iran (Mansoori 2012). Under local conditions of Saudi Arabia, date palm trees are vulnerable to infection with some destructive diseases which are responsible for decline and considerable losses in the number of trees or its yield. At week 8, all plants showed severe discoloration and mortality rate reached to. American Phytopathological, Soytong, K., Pongak, W., and Kasiolarn, H. 2005. This study addresses the gap of information on potential chemical and biological control agents that might find potential application to control mango quick wilt disease. The effect of. (2010), the thick-walled aleuroconidia were, borne singly from short hyphal branches, colored pale brown to, brownish black. C. radicicola is reported to cause black scorch in Kuwait under drought and salinity conditions (Suleman et al., 2001). (Abdullah et al. T. punctulata, Date palm orchards suffer from serious diseases, including sudden decline syndrome (SDS). Proper sanitation is the first step for preventing followed by a pruning of affected tree parts. Effect of fungicides, Trichoderma and plant extracts on mycelial growth of, Chase, A. R., and Broschat, T. K. 1993. populi, and Ch. A. 90:972. 1C) and at different ages of date palm. amplifications of internal transcribed spacer (ITS), 28S ribosomal DNA, relationship of fungal sequence with the most related ITS sequences in GenBank. In order to avoid any, (Paulin-Mahady et al. trunk rot of date palm in Italy. We also found that the fungicide Cidley Top® inhibited the mycelial growth of T. punctulata and F. solani both in vitro and in vivo. At 1 wpi, leaves were recorded as having the highest value in DSI among all. Black Scorch: This disease is also called ‘Fool’s disease’, caused by a fungus. Altogether, the pathogenicity tests, disease severity indices and mode of action tests confirmed that the BCA was not only capable of suppressing black scorch disease symptoms, but also could prevent the spread of the pathogen, as a potential practical method to improve disease management in the palm plantations. amined for black scorch symptoms after 1, 2, and 4 weeks.
