Macrophomina phaseolina (Tassi goid) is a pathogen that causes Charcoal rot of mungbean resulting in to a great economic loss. In the present study effect of Ocimum sanctum L., Calotropis procera (Ait.) Ait. f. and Astragalous tribuloides Delile extract on the survival of Macrophomina phaseolina was studied. The variety of different extracts of Ocimum sanctum L., Calotropis procera (Ait.) Ait.f...
Seedlings of Corchorus capsularis (cv. C4444) were inoculated with Meloidogyne incognita, Hoplolaimus indicus, and a fungus pathogen of jute, Macrophomina phaseoli, separately and in all possible combinations. The significant damage of jute plants caused individually by the pathogens was aggravated when the fungus was associated with either of the nematode species. M. incognita alone caused gre...
Macrophomina phaseolina is one of the deadliest necrotrophic fungal pathogens that infect more than 500 plant species including major food, fiber, and oil crops all throughout the globe. It secretes a cocktail of ligninolytic enzymes along with other hydrolytic enzymes for degrading the woody lignocellulosic plant cell wall and penetrating into the host tissue. Among them, lignin peroxidase has...
Incidence and severity of root-rot caused by the fungus Macrophomina phaseoli was increased in screenhouse-grown kenaf (Hibiscus cannabinus L.) seedlings simultaneously infected by the nematode Meloidogyne javanica. In seedlings inoculated at 5, 10 and 15 days of age, root rot lesions increased 70.3, 44.1 and 21.8%, and nematode penetration increased 49.0, 36.7, and 12.3% when both fungus and n...
در سالهای 1386 و 1387 از مزارع باقلا در استان لرستان از گیاهان مشکوک به پوسیدگی ریشه و طوقه باقلا، نمونهبرداری شد و در مجموع 121 جدایه قارچ و کرومیستا جدا شد. در این بررسی مشخص شد که فراوانی قارچ Fusarium solani که موجب پوسیدگی ریشه باقلا میشود، از سایر جدایهها بیشتر و خسارت ناشی از آن در مزارع استان زیاد است و بعد از آن بیشترین فراوانی به ترتیب متعلق به گونههای F. oxysporum، Rhizoctonia ...
Macrophomina phaseolina is a serious pathogen of many crops. In the present studies, 65 isolates of Macrophomina phaseolina from different agroecological regions of Punjab and Khyber Pakhtunkhwa provinces of Pakistan were analyzed for morphological and pathogenic variability. Regardless of their geographic origins, significant differences were detected among 65 isolates in their radial growth, ...
