The soil borne, obligate biotrophic fungus Synchytrium endobioticum causes tumor-like tissue proliferation (wart) in potato tubers and thereby considerable crop damage. Chemical control is not effective and unfriendly to the environment. S. endobioticum is therefore a quarantined pathogen. The emergence of new pathotypes of the fungus aggravate this agricultural problem.

Groundnut (Arachis hypogaea L.) is a cultivated annually belonging to the plant family Leguminosae and sub family Papillionaceae. In groundnut several soil borne disease is occurred. Among them dry root rot is major which caused by Macrophomina phaseolina (Tassi) Goid has been having worldwide importance devastating disease causes severe losses in yield. Invitro, the effectively colony growth of fungus M. phaseolina was inhibited through different bioagent.

Verticillium wilt, caused by the soil borne fungus Verticillium dahliae, is a major threat to cotton production worldwide. An increasing number of findings indicate that WAK genes participate in plant−pathogen interactions, but their roles in cotton resistance to V. dahliae remain largely unclear.

Rhizoctonia solani Kuhn (Teleomorph: Thanatephorus cucumeris) is a soil borne, polyphagous, necrotrophic plant pathogenic fungus with a wide host range. It is causing sheath blight disease on a wide range of Graminae plant hosts and causes considerable losses in yield. It incites banded sheath blight disease in small millets, with its characteristic copper brown band symptoms. Fifty three isolates of Rhizoctonia solani were obtained from four different small millets showing typical symptoms of the disease.

The cluster bean (Cyamopsis tetragonoloba L.Taub.) also known as Guar is one of the most important commercial crop and major source of guar gum. The clusterbean is affected by various fungal diseases. Among those dry root rot caused by Macrophomina phaseolina (Tassi) Goid., a soil borne, cosmopolitan fungus infecting cluster bean and more than 500 plant species. The first symptom of disease is yellowing of the leaves, dark lesion may be seen on the bark at the ground level, the basal stem & main root may show dry rot symptoms.

Sesame (Sesamum indicum L.) is aprimitive oilseed crops cultivated in semi-arid Tropics and sub tropics regions in India. Macrophomina phaseolina a soil borne fungus cause root and stem rot in sesame crop and pathogen attacks plant at all growth stages. Due to soil borne nature practically no effective field control and no source of resistant is available. A field experiment was conducted with twenty cultivars of sesame during kharif sesame 2017.

Cabbage is one of the most widely cultivated vegetables of the temperate zone. Cabbage is susceptible to many foliar and soil borne diseases, among the soilborne fungal diseases of cabbage, white head rot disease caused by Sclerotinia sclerotiorum is a potential threat to cabbage production and limits the crop cultivation and it is also associated with root-knot nematode (Meloidogyne incognita).

Several biotic and abiotic constraints significantly reducing the chickpea area and production over last two decades. Among biotic stresses, fusarium wilt caused by Fusarium oxysporum f. sp. ciceri (Foc) is the major soil-borne fungus affecting chickpea production globally. This Fusarium wilt disease affects chickpea not only quantitatively but also qualitatively. The development of resistant varieties is the most effective method to manage this disease and to stabilizing its productivity.

Rice is an important staple food for more than half of the world’s population and is subject to diseases that often place major biological constraints on production. Sheath blight of rice is caused by a soil borne fungus and biological control of the disease is an efficient substitute to replace chemical methods. In the present study thirty native fluorescent Pseudomonads, an efficient biocontrol agent have been isolated and confirmed by cultural, morphological, biochemical characterization and visualization under UV light.

Ancestral wheat relatives are important sources of genetic diversity for the introduction of novel traits for the improvement of modern bread wheat. In this study the aim was to assess the susceptibility of 34 accessions of the diploid wheat Triticum monococcum (A genome) to Gaeumannomyces graminis var. tritici (Ggt), the causal agent of take-all disease.

Fusarium oxysporum f. sp. lycopersici causing tomato wilt is a common soil borne fungus. Bio-control agents could be used as an eco-friendly approach to effectively control the disease and may be advised to the farmers for profitable organic farming. The fungal (Trichoderma harzianum) and bacterial (Bacillus subtilis and Pseudomonas fluorescens ) biological control agents were tested for their compatibility in vitro to determine whether they can be used in combination.

Rhizoctonia solani Kühn [teleomorph :Thanatephorus cucumeris (Frank) Donk] is the most destructive and widely distributed soil borne pathogenic fungus causing black scurf of Potato. Cultural and morphological variability was studied in eleven potato isolates of R. solani collected from different potato growing areas including Haryana, Punjab, Uttarakhand, Rajasthan and Maharashtra etc. Based on the radial colony growth rate, all the isolates were categorised into 3 groups as slow, medium and fast growing. Majority of isolates showed slow colony growth rate.

Cowpea [Vigna sinensis (L.) Savi] is an ancient legume crops and major source of protein. The cowpea is affected by various fungal diseases. Among those Colletotrichum lindemuthianum is a seed and soil borne fungus causing the anthracnose disease in Cowpea. Most of the promising cowpea cultivars are under a great threat for profitable cultivation due to the attack of Fungi, bacteria, virus and nematodes. The major losses of cowpea are covered by fungi, in which anthracnose caused by Colletotrichum lindemuthianum is more important.

Dry root rot caused by Rhizoctonia bataticola (Taub.) Butler is emerging as a serious biotic constraint for chickpea production. It is soil borne fungal pathogen. The losses in chickpea due to Rhizoctonia bataticola may be as high as 60 per cent. The eight isolates of Rhizoctonia bataticola were collected from different districts of Maharashtra. The genomic DNA of 8 isolates of Rhizoctonia bataticola isolated from fresh mycelium of fungus grown in Potato Dextrose Broth solution and subjected to amplification with RAPD marker for diversity analysis.
