Hydroxylation of (+)-menthol byMacrophomina phaseolina

Biocatalysis and Biotransformation, 2011
AbstractBiotransformation of (+)-menthol with Macrophomina phaseolina led to hydroxylations at C-1, C-2, C-6, C-7, C-8 and C-9, with the C-8 position being preferentially oxidized. The resulting metabolites were identified as 8-hydroxymenthol (2), 6R-hydroxymenthol (3), 1R-hydroxymenthol (4), 9-hydroxymenthol (5), 2R,8-dihydroxymenthol (6), 8S,9 ...

Effect of herbicides on survival of Macrophomina phaseolina in soil

Transactions of the British Mycological Society, 1980
The effect of five herbicides, EPTC, dinoseb, alachlor, fluorodifen and fluometuron, on the inoculum density of Macrophomina phaseolina (Tassi) Goid. was tested in two field soils. The herbicides were applied at commercially recommended rates. All herbicides tested incited a significant drop in the population of M. phaseolina.

Macrophomina phaseolina in the Sonoran Desert

Canadian Journal of Botany, 1989
The relationship between microsclerotial populations of Macrophomina phaseolina (Tassi) Goid. and selected perennial species was investigated at five native Sonoran Desert sites. The population level of M. phaseolina was found to have an inverse relationship with the presence of several plant species, including Acacia constricta and Larrea tridentata,

Method for detecting Macrophomina phaseolina

2022
The plant pathogen Macrophomina phaseolina is distributed worldwide and has a host range of more than 500 plant species. The fungus attacks crops that are the source of staple foods, and causes yield losses of up to 90% in sunflower, 30-60% in strawberry, 50% in soybean and 70% in corn.

Variation in the responses of melon and watermelon to Macrophomina phaseolina

Crop Protection, 2016
Abstract Macrophomina phaseolina is the causal agent of charcoal rot disease, which attacks many plant species, including those in the Cucurbitaceae. The fungus is frequently isolated from wilted melon and watermelon plants in Israel. Nevertheless, the role of M.

Germinability of sclerotia of Macrophomina phaseolina

Canadian Journal of Botany, 1978
The germination of sclerotia of Macrophomina phaseolina from 3- to 20-day-old PDA cultures incubated at 32 °C and 24 °C varied from 98 to 25% and 75 to 30%, respectively. Germinability of sclerotia from cultures of all ages tested was rapidly lost during storage in desiccators for 24 h at 6 °C or in screw-top vials at room temperature for 30 days ...

Diallel Analysis of Resistance to Macrophomina phaseolina in Sorghum

Cereal Research Communications, 1999
Charcoal rot of sorghum, caused by the fungus Macrophomina phaseolina, is a severe disease in regions where sorghum encounters post-anthesis drought stress. Previous reports disagree with respect to the narure of the genetic factors that condition resistance to charcoal rot.

Macrophomina phaseolina causing leaf spot of mungbean

Australasian Plant Pathology, 1996
Macrophomina phaseolina, causing leaf spot of mungbean is reported in Australia. Koch's postulates were fulfilled. The inoculum source was considered to be microsclerotia of the fungus in soil splashed onto the leaves. The disease is not expected to be a problem in Australia in most years.
