Crown rot disease caused by Lasiodiplodia theobromae (Pat.) Griffon and Maubl. and Colletotrichum musae (Berk and Curtis) Arx. is the major problem in banana cv. Robusta. Efficacy of application time of biocontrol agents in postharvest environment in relation to pathogen infection is an important factor in controlling the crown rot disease of banana. Trichoderma viride isolates TV3 and TV4 which showed effectiveness against both pathogens in vitro were applied at different time intervals in relation to the time of pathogen inoculation in order to know the effective application time of biocontrol agents. Biocontrol agents were applied 2 and 4 h before pathogen inoculation; simultaneous challenge inoculation; and 2, 4 h after pathogen inoculation. The results indicated that the highest reduction of crown rot disease of banana was achieved when the biocontrol agents were applied 4 and 2 h before pathogen inoculation (preventive method of application) compared with the other treatments.Keywords

Wilt disease caused by Fusarium verticillioides is a major constraint in cultivation of maize. To manage the wilt pathogen, one native Trichoderma sp., viz., T. viride (NTV) and an isolate of T. harzianum, NBRI 1055 received from NBRI were evaluated for their antagonistic potential in vitro. Among them, T. harzianum NBRI-1055 isolate was more effective on F. verticillioides than T. viride (NTV) with 69.46 per cent inhibition. In further study, seed treatment with T. harzianum (2.0% WP) @ 40 g kg-1 + soil application of T. harzianum @ 2.5 kg ha-1 and seed treatment of T. harzianum @ 20 g kg-1 + soil application of T. harzianum @ 2.5 kg ha-1 recorded the least wilt incidence both in pot culture and in field trials. There was a direct correlation between the disease control and the plant growth. In addition, better plant growth, higher yield, maximum shoot length, dry matter production and dry weight of cobs were recorded with seed treatment of T. harzianum (2.0% WP) @ 40 g ha-1 + soil application @ 2.5 kg ha-1 and followed by seed treatment of T. harzianum @ 20g kg-1 + soil application @ 2.5 kg ha-1.Keywords
