Creating
epiphytotics of Rhizoctonia root rot and evaluating for resistance to Rhizoctonia solani in sugarbeet field plots.
A total of 36 hybrids were produced in half diallel fashion during summer-2014-15 and were screened for TLB under artificial
epiphytotic condition during kharif 2015.
In the last few years, disease has been observed in almost
epiphytotic form and could cause up to 20-100% losses in yield (12, 11).
FC710 (4X) also exhibited moderate resistance to cercospora leaf spot when tested in an artificial
epiphytotic (Ruppel and Gaskill, 1971).
Screening of thirty two pea germplasm under natural
epiphytotic condition was carried out in the field during Rabi season 2013-14 and 2014-15 at N.E.
Under natural
epiphytotic conditions, significantly lower Phytophthora blight was found in trellis system among the two commonly adapted planting systems of pointed gourd.
For the confirmation of resistance, a field experiment was conducted during kharif and rabi 2015 at College of Agriculture, University of Agricultural and Horticultural Sciences, Shivamogga under natural
epiphytotic conditions.
Heavy rains during July and August of 1990 flooded low areas of this turf trial and were followed by a severe
epiphytotic of Pythium blight [caused by Pythium aphanidermatum (Edson) Fitzp.].
