Ashy stem blight [caused by Macrophomina phaseolina (Tassi) Goid.] can be a serious disease of common bean (Phaseolus vulgaris L.) under drought and high temperature conditions in some regions. The mode of inheritance of valuable sources of resistance is lacking. We studied inheritance of field resistance to ashy stem blight in a recombinant inbred population (’Dorado’ × XAN 176) consisting of ...

Brown stem rot (BSR) of soybean [ (L.) Merr.] caused by (Allington & Chamb.) T.C. Harr. & McNew can be controlled effectively with genetic host resistance. Three BSR resistance genes , , and , have been identified and mapped to a large region on chromosome 16. Marker-assisted selection (MAS) will be more efficient and gene cloning will be facilitated with a narrowed genomic interval containing ...

in order to study the role of pythium species associated with cantaloupe root and crown rot, samples were collected from infected fields in different areas of khorasan razavi province during 2009-2010. the root pieces were washed and cultured on cma-parp medium. the pythium isolates were then purified by hyphal tip method and identified based on van der plaats-niterink mycological key. the path...

The effect of 3 organic soil amendments viz., cassava peel (Manihot esculenta, Cranz), sawdust (Gmelina arborea, Roxb) and leaves (Cedrela odorata, L) on the stalk rot maize (Zea mays L.) caused by Fusarium verticillioides was investigated. Fourteen treatments made up single or combined with pathogenic non-pathogenic inoculation concentrations 3:1, 2:2 1:3 were added to 15.8 g sterilized soil. ...

Stem rot disease was found in garlic (Allium sativum L.) cultivated from 2008 to 2010 in the vegetable gardens of some farmers in Geumsan-myon, Jinju City, Gyeongnam province in Korea. The initial symptoms of the disease were typical water-soaked spots, which progressed to rotting, wilting, blighting, and eventually death. White mycelial mats had spread over the lesions near the soil line, and ...

The possibility of inducing resistance to bitter rot (Colletotrichum gloeosporioides), brown rot (Monilinia fructicola), and green mold (Penicillium digitatum) in apples, peaches, and tangerines, respectively, by treating them with ultraviolet light-C (UV-C light) at the stem end in a stationary position without rotation was investigated. This approach was compared with the conventional procedu...
