Abstract
Peroxidase and Polyphenoloxidase Activities as Biochemical Markers for Biocontrol Efficacy in the Control of Tomato Bacterial Wilt
We have studied the effect of certain bioagents for the control of bacterial wilt of tomato under greenhouse and field conditions and the effect of these bioagents in induction of some enzyme activity in planta e.g. Peroxidase (PO) and polyphenoloxidase (PPO). Under greenhouse conditions the effect of Pseudomonas putida and P. fluorescens, and their combination were studied, and we found that both of them reduced the disease 60 and 66.67%, respectively and the combination treatment reduced the disease 53.33%. Also under field conditions P. putida was the best in reduction of the disease followed by the combination and then P. fluorescens. The P. fluorescens treatment recorded the highest percent yield increase in the two trails.
