Integrated management of collar rot and pod rot diseases in groundnut

Abstract

Groundnut (Arachis hypogaea L.) is one of the important oilseed crop grown in India which is affected by several diseases. Among these diseases, collar rot caused by Aspergillus niger and pod rot caused by Macrophomina phaseolina are economically important. For the management of these diseases of groundnut various treatments were imposed. The fungicides and bio control agents with agronomical practices were tested against these diseases in groundnut. The experiment comprised of seven treatments replicated thrice in design RBD during Kharif - 2015 to 2017 at Oilseeds Research Station, Jalgaon. The results that revealed that the treatment, Deep summer ploughing with mould board plough + Soil application of Trichoderma @ 4 kg/ ha enriched in 250 kg FYM/ha +Seed treatment with Tebuconazole 2DS 1.5 g/kg seeds followed by seed treatment with PGPR @625g/for per ha of seeds+ Soil application of Trichoderma @ 4 kg/ ha enriched in 250 kg FYM/ha at 35 and 70 DAS showed the highest germination 92.04% as against 73.43% in the control. The same treatment also recorded the least incidence of collar rot at 30 DAS 2.93% and pod rot at harvest 2.89% as against 10.79% and 7.53% in control, respectively.
