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.

An experiment was conducted to study influence of physiological parameters like temperature, pH and light period on growth and sporuation of Macrophomina phaseolina, the incident of stem and root rot of sesame. It is found that, the pathogen grew best at neutral pH i.e. pH 6.5 (285.8 mg) followed by pH 7 (278.0 mg). The temperature of 350 C is best for mycelial growth of M. phaseolina followed by 300 C while no growth was found at lower temperatures. The growth of fungus reduces as the temperature increases or decreases.

A survey was conducted in major groundnut growing areas of Karnataka during kharif 2013 and kharif 2014 to identify hot spots of stem and pod rot of groundnut. A total of 80 different locations of eight districts of Karnataka were covered during the survey. During kharif 2013, the highest stem rot (62.80%) and pod rot (73.67%) was recorded in Chitradurga district followed by Tumkur district which recorded stem rot incidence of 42.59% and pod rot of 40.70%.

Efficacy of fungicides and herbicides was tested using poison food technique against Sclerotium oryzae. Out of eight fungicides tested against S. oryzae, the stem rot pathogen propiconazole @ 100 ppm and hexaconazole @ 200 ppm were found effective in inhibiting the mycelial growth of S. oryzae by 100 per cent followed by Carbendazim (97.98%), Tebuconazole (97.77%) and Mancozeb (97.76%) which were found on par with each other in inhibiting the mycelial growth of the test pathogen.

In vitro antagonism of native biocontrol agents on coconut pathogens revealed that all the three isolated native Trichoderma spp were found inhibitory to the mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora. Maximum percent inhibition of mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora was obtained by Trichoderma viride followed by Trichoderma hamatum and Trichoderma harzianum.

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.

Thirty fungal endophytic isolates were recovered from leaf, stem, root and inflorescence of mulberry plant and the morphological characterization was done. The antifungal potential of isolated mycoendophytes against Macrophomina phaseolina was evaluated in vitro by dual culture technique and revealed that ENF20 isolate reduced the mycelial growth by 82.22 per cent over control followed by ENF12 (80.56 per cent), ENF11 (77.78 per cent), ENF13 (76.11 per cent).

Lentil (Lens culinaris Medik) is an important crop, the major states producing lentil are Madhya Pradesh, Uttar Pradesh, Bihar and Punjab. Lentil is an important component of farming systems in our country. It is one of the important and most nutritious rabi pulses. Vascular wilt causing by Fusarium oxysporum f.sp. lentis, Sclerotium rolfsii Sacc. causing collar rot and Sclerotinia sclerotiorum (Lib.) de Bary) causing stem rot, is most destructive soil borne diseases of lentil growing area worldwide. Use of chemicals continues to be major strategy to mitigate the menace of crop disease.

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.

Groundnut is a major legume and important oil seed crop belongs to family Fabaceae. A large number of diseases attack groundnut plant in India, of these stem rot caused by Sclerotium rolfsii is the most common disease. The present study was conducted in experimental field of SHUATS for management of stem rot disease of groundnut (Sclerotium rolfsii) which is most important destructive disease of groundnut in India. Therefore present studies were undertaken to test Trichoderma viride, Neem cake, vermicompost and the combinations along with the treated check (Vitavax).

The present investigation was aimed to understand early infection process and plant pathogen interactions involved in tolerance and susceptibility in groundnut challenged with Sclerotium rolfsii by Scanning Electron Microscopy (SEM). The histo-pathological changes were recorded at different time intervals in two groundnut genotypes with differential reaction to stem rot disease viz., Cv: “ICGV 86590” (resistant) and Cv: “Narayani” (susceptible). These genotypes were grown in glass house and challenged with stem rot pathogen.

Intensive screening of black pepper germplasm through artificial inoculation was done at ICAR-Indian Institute of Spices Research, Kozhikode, (Kerala, India) to locate sources of resistance against Phytophthora foot rot incited by Phytophthora capsici Leon. adopting conventional stem and leaf inoculation procedure. The intact stem and leaf of 3-4 leaf stage rooted plants were inoculated and incubated for 72h at a temperature of 25 –28° C with a relative humidity of 80 – 90% for development of symptoms.
