Stem rot is a potential threat to mustard and set as key disease in mustard growing area. the first symptoms appearance as elongated, water soaked spots then further it expands rapidly after 45-55 days after sowing that causes upto 81.5% losses with significantly reduction in yield. the findings revealed that carbendazim, thiophnatemethyl and propiconazole @ 0.1 percent and garlic, turmeric, eucalyptus spp., zingiber and azadirechta@ 20 percent, while, amritjal @ 15 percent were found significantly inhibited the growth and development of s. sclerotiorum under in-vitro. apart, reduced the girdled length on stem, numbers of sclerotium and surviving viability in soil under field evaluation. stem rot lowest girdled length on stem 1.76 cm, was noticed in carbendazim with 318.18 kg ha-1 statistically significant (p < 0.005) superior and at par with each other followed by allium sativum, eucalyptus amydalin, amritjal and trichoderma harzianum. it concluded that summer deep ploughing, trichoderma applied at time field preparation in incorporated with farm yard manure prepared inoculated active inoculum load of trichoderma harzianum then spraying of effective treatment before appearance of stem rot symptoms
