- Abstract:
- ... BACKGROUND: Nano-particles of metals can be routinely synthesized. The cereal seeds treatment with the particles can improve early growth and crop production. Moreover, the treatment is robust and economical. METHODS: Metal (Fe⁰, Cu⁰, Co⁰), zinc oxide (ZnO) and chitosan-stabilized silver nano-particles were synthesized and applied to cereal seeds. The germination rate, early plant development and ...

Fifty foliar blight diseased samples collected from wheat, barley and oat growing areas of north-western India revealed that Bipolaris sorokiniana was present in all the isolates collected from barley, wheat and Phalaris minor, while Drechslera avenae was associated with isolates from oats. All the test isolates were pathogenic on their susceptible check viz., PL426 (barley), HD-2329 (wheat), OL-9 ...

- Abstract:
- ... Foliar blights of graminaceous host are one of the important fungal diseases causing considerable losses to the crops. Under Punjab conditions, foliar blight/spot blotch of wheat and barley (Bipolaris sorokiniana) and leaf spot of oats (Drechslera avenae) are one of the devastating fungal diseases causing considerable reduction in the grain yield. Fifty leaf samples showing typical disease symptom ...

- Abstract:
- ... Browntop millet (Brachiaria ramosa [L.] Stapf), which is native to India, was recently introduced as one of the small millet crops. In September 2018, leaf blight symptoms were observed on cultivar Dundu Korale on the adaxial side of the leaves in a field at Bangalore, India (13.0784°N, 77.5793°E). Initial lesions were brown with a small yellow halo that ranged from 1 to 5 mm and eventually enlarg ...
