摘要

The ED50?value of antagonistic substance from?Chaetomium?globosum?N0802 extracted with hexane was 157 μg/ml. This gave the highest inhibition of conidial production of?Fusarium oxysporum?f. sp.?lycopersici?causing tomato wilt var Sida. Crude hexane from?Chaetomium?lucknowense?CLT and crude methanol fromTrichoderma harzianum?PC01 gave ED50?values of 188 and 192 μg/ml. ?It clearly demonstrated that antagonistic substances from all tested fungi could be deformed and this could break the conidial cells.? The bio-agent formulations namely N0802, CLT and PC01 gave significantly highest disease reduction of tomato wilt which were 44.68, 36.28 and 41.01%, respectively, followed by prochoraz (21.95%). All tested bio-agent formulations could significantly increase the yield of tomato when compared to prochoraz and inoculated control. It is concluded that?C. globosum,?C.lucknowense?and?T. harzianum?developed as bio-agent formulations namely N0802, CLT and PC01 and showed their abilities to control tomato wilt.
