Phytophthora is a long-established, well known and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from at least twice. Since, cladistically, this renders ‘paraphyletic’, it been proposed evolutionary clades be split into multiple genera (Runge et al. 2011; Crous 2021; Thines 2023; 2024). In letter, we review arguments for retention generic name with broad circumscription made by Brasier...
Aspergillus spp. has been widely found as useful microorganism in biotechnology. They have a high ability the production of secondary metabolites. Therefore, isolates were isolated from healthy rice field located Selangor State/Malaysia. The obtained strain (UPMZ01) was conducted against Pyricularia oryzea by applying dual culture and filtrate technique. antagonism UPMZ01 81.326% inhibition percentage P. oryzae given optimum inhibitory 100% at all concentration metabolites aged 14 days....
Abstract The core findings of this study revealed that physicochemical properties fluctuate with soil texture and class. Sandy showed inconsistent variation geographical directions. Bulk density, lime content, EC pH decreases topography elevation while these parameters increased from surface to subsurface within a profile. Nitrogen, phosphorus, potassium micronutrient increase in elevation. All decreased soil. Water holding capacity saturation percentage elevation, Based on the critical...
Black pod, caused by Phytophthora spp., occurs worldwide and is a major problem for cocoa farmers in Malaysia. Limited studies addressed causal agents of black pod disease Malaysia as well their genetic diversity. Therefore, this study was initiated to isolate identify from the main plantations infected using sequence analyses ITS rDNA, EF-1α, COX1 gene regions. A total 36 isolates were obtained five states 2016 14 2013. Six durian crop, “the king fruit”, 2013 also used study. Results...
Gray mold disease is caused by Botrytis cinerea and it the most significant devastating affecting tomato cultivation worldwide. This was recently reported infecting fruits in Cameroon Highland, Pahang. Biocontrol agents have been proven to be effective towards many phytopathogens. In this study, 43 bacterial isolates were screened against B. in-vitro. Five with more than 65% inhibition of radial growth (PIRG) selected for subsequent experiments. Findings dual culture assay revealed that BM11...
Black pod caused by Phytophthora palmivora causes major losses on cocoa (Theobroma cacao) in Malaysia and worldwide.In this study, morphological molecular characterization as well pathogenicity of 14 isolates P. palmivora, obtained from main producing states Peninsular including Perak Pahang, were determined.In general, the results indicated that divided into two groups based their geographical origins isolates.According to characteristics, although some overlap was observed among states,...
Coconut (Cocos nucifera) is a high economic value cash crop in Malaysia. In December 2021, irregular spots with dotted rust-like appearance were observed mainly on the tip of leaves MATAG variety coconut seedlings at nursery Perak state. More than 90% surveyed infected leaf spot symptoms. These symptoms could bring huge losses due to downgrade seedlings. 15 symptomatic obtained from nursery, 10 mm2 cut disinfected 10% sodium hypochlorite for minutes and rinsed sterile distilled water before...
