Bio agents

In the present study, an attempt has been made to isolate endophytic bacteria mainly belonging to Pseudomonas genus from potato possessing ability to work as plant growth promoting bacteria (PGPB) as well as biocontrol agent.

Three bio-agents i.e. Trichoderma viridae, Trichoderma harzianum and Trichoderma aspergillum were evaluated against Botrytis cinerea under in vitro condition. Culture disc of fungal bio-agents and pathogen were taken from the growing cultures and transferred to PDA contained in 70 mm petridishes on opposite sides approximately at one cm from the wall of the plate. Among these three bio-gents Trichodema harzianum showed best mycelial growth inhibition of Botrytis cinerea.

Foot rot of tomato is an important disease which causes severe loss in tomato production. The present study was carried out to evaluate five bioagents and six fungicides against Sclerotium rolfsii. Among the five antagonists tested the maximum inhibition was observed in Trichoderma virens (67%) and contrarily, no inhibition was observed in Bacillus subtilis. Six fungicides viz., carbendazim, captan, tebuconozole, copper oxychloride, hexaconozole and Tebuconazole +Trifloxytrobin at different concentrations (50, 100, 150, 200, 250 and 500 ppm), were tested.

The study was carried out during 2013-14 in Meerut district of Uttar Pradesh state to focus on the sugarcane growers regarding impact of knowledge on adoption level of IPM practices. The 80 contact farmers were selected as respondents. The study revealed that the maximum knowledge gap was found to be existing in previous crop residues, crop rotation, hand picking of the insect and their destruction, hot air and water treatment, light and pheromone trap, microbial control, use of natural enemies, resistant varieties, biopesticides/ bio-agents, application and dose of different pest etc.

H2O2 generation is a limiting step in thyroid hormone bio-synthesis. Biochemical studies have confirmed that H2O2is generated by a thyroid Ca 2+ /NADPH-dependent oxidase. Decreased H2O2 availability may be another mechanism of inhibition of thyroperoxidase activity produced by thio-ureylene compounds, as propylthiouracil (PTU) and methimazole (MMI) are antioxidant agents. Therefore, we analyzed whether PTU or MMI could scavenge H2O2or inhibit thyroidNADPHoxidase activityin vitro.

We used a proteomic approach to identify constitutively formed extracellu-lar proteins of Hypocrea atroviridis(Trichoderma atroviride), a known bio-control agent. The fungus was cultivated on glucose and the secretome was examined by two-dimensional gel electrophoresis.
