Groundnut in parts

Stem and pod rot of groundnut caused by the pathogen Sclerotium rolfsii, which has a wide host range and it affects the yield losses up to 30-40% in groundnut in India. The persistence of infection caused by sclerotia of S. rolfsii inciting disease stem and pod rot of groundnut following the incorporation of mustard (Brassica nigra) plant parts into soil was examined through an experiment under greenhouse conditions.

Twenty eight fungal endophytes were isolated from leaves, 33 from stem and 21 from root, resulting in a total of 82 fungal endophytes from apparently healthy groundnut plant parts and evaluated these endophytes against major fungal pathogens viz., Sclerotium rolfsii and Rhizoctonia solani by dual culture technique and against Puccinia arachidis by spore germination technique.

A roving survey was carried out during Kharif 2017 in different groundnut growing districts of Karnataka to ascertain the major soil borne diseases of groundnut viz., collar rot, stem rot and root rot disease incidences in Chikkaballapura, Tumkur, Chitradurga, Bellary, Raichur, Yadgiri, Koppal and Kalburgi districts of Karnataka. The average highest collar rot incidence was noticed in Kalaburgi (16.00 %), dry root rot incidence in Koppal (25.25%) followed by Tumkur (24.37%), stem rot incidence in Chitradurga (22.72%) followed by Tumkur (21.22%) districts of Karnataka.

Groundnut (Arachis hypogaea L.) is an important edible leguminous oilseed crop. Diseases of groundnut act as the limiting factor to its economic production. Recently, the stem rot caused by Sclerotium rolfsii is becoming severe disease of groundnut in India. Crop Losses up to 59 per cent due to stem rot disease have been reported by many researchers.
