Replant disease is a major problem of apple orchards, which is a main cash crop in TransHimalayan region. The cause of this replant problem includes both biotic and abiotic factors, such as low nutrients, phytotoxins, actinomycetes, fungal complexes and nematodes. Fungi and oomycetes belonging to the well-known root rot complex are important factor of replant problems in apple.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

The present study was conducted to evaluate bacterial endophytes against Pythium spp. causing soft rot of ginger. Water soaked lesions at the emerging base and the collar region was the typical symptoms observed on infected plants. Sprout appeared pale yellowish and withering off of plant was seen and such rhizomes were rotten and emitted foul smell in which diseased plants came off with a gentle pull.

Bacteria producing biosurfactant molecules is beneficial to manage rhizome rot of turmeric caused by Pythium spp. A detailed study was conducted on biosurfactant producing bacteria for management of rhizome rot of turmeric. Initially, a survey was conducted to find out the incidence of the disease in turmeric growing of areas of Tamil Nadu, it was observed that rhizome rot in turmeric was also ranged from 9.16 to 71.55 and the maximum incidence was noticed in Ammampalayam (71.55%).

Turmeric is one of the important spice crops grown in India. Root-knot nematode (Meloidogyne spp.) is a major problem, which causes galls/knots in the rhizomes and causes considerable yield loses. It also makes the way for the secondary infection by different pathogens like Pythium, Fusarium and Ralstonia in the soil. Yield losses due to nematode infestation are reported in turmeric-growing areas. A roving survey was conducted for incidence of root-knot nematode in turmeric during kharif season in 2016 at Belagavi, Bagalkot, Chamarajanagar and Kalburgi districts of Karnataka.

The experiment was carried both in in vitro and in situ during 2017-18 at Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad to evaluate the efficacy of Trichoderma isolates against Pythium sp. Under in vitro condition the results revealed that Trichoderma sp. (isolate 5) effectively inhibited the radial mycelial growth of Pythium sp. (71.66 %). Under in situ conditions Trichoderma isolates were tested against the damping off (Pythium sp.) disease of radish.

The present study was conducted to evaluate the in vitro efficacy of native Trichoderma spp. against Pythium spp. and Rhizoctonia solani (Kuhn.) causing damping-off disease in Tomato. One hundred eighty soil samples were collected from 11 districts of Meghalaya and ninety seven Trichoderma isolates were obtained. Rapid screening against damping off pathogens (Pythium spp. and R. solani) of tomato revealed that 20 isolates showed maximum antagonism and subsequently 20 best isolates were selected for further analysis.
