Saproon valley of Himachal Pradesh is famous for seed production of late Snowball Cauliflower where recurrence of stalk rot incited by Sclerotinia sclerotiorum (Lib.) de Bary has caused huge losses, (84-100%) (Sharma, 1979). Since the disease is soil borne and the pathogen perpetuates through sclerotia, its management by the use of chemicals is uneconomical. Investigations were, therefore, undertaken to isolate the rhizosphere fungi of cauliflower and to study their inhibitory effect on the pathogen.Keywords

Ginger (Zingiber officinale Rosc.) an important spice crop grown in different states of India especially Himachal Pradesh, a hilly area situated in northern Himalayas. Pythium and Fusarium are the main fungus which affect the crop in a drastic manner. Ginger rhizome diseases are both rhizome seed and soil borne and their chemical management leads to notorious effect on environment and ecosystem. Therefore, an attempt to work out for isolation of Pythium and Fusarium sp. (major pathogens causing ginger rot) from Sirmaur and Solan areas of the state and research emphasized on non-chemical management of these fungal diseases. Hot water treatment of ginger rhizomes at different temperatures excluded the maximum rhizome borne inoculum through eradication. Among the biocontrol agents T. harzianum was found more effective for pathogenic fungal inhibition recorded as (50.28%) followed by T. hamatum (44.94%) and Streptomyces sp. (40.11%).Keywords
