| Abstract:
In this study, effects of plant activators in standard grower practices were evaluated for yield, and some quality properties of processing tomato as well as disease management. It was found significant differences on tomato plants among plant activator applications and untreated plot. The number of cluster, flower, fruit and ripe fruit were determined as main characters affecting directly on yield of tomato. The highest yield were obtained from the plots where Bion MX 44 WG, Messenger, and ISR-2000 + Crop-Set, respectively. More yield compare to control plot were harvested as 71% from Bion MX applied plot, as 64% from Messenger applied plot, and 59% from ISR-2000 + Crop-Set applied plot. In terms of tomato paste, better yield and quality also were obtained from activator appled plots compare to control one. Early maturity was observed from Messenger applied plants. In results, Bion MX was found to have the highest positive effects on quality such as brix and fruit size, however, it could be of limited use because of residue problem of 40% metalaxyl. Moreover, ISR-2000 + Crop-Set combination also had high values in both brix and tomato paste yield. Less diseases were observed from the activator treated plots compare to untreated one. | |
