Tomato Plant Protection Management to Reduce Fusarium Wilt Disease by Utilizing Plant Growth Promothing Rizobacteria Pseudomonas alcaligenes

I Ketut Widnyana, IGN Alit Wiswasta, Anik Yuesti

Abstract: Tomato plants are susceptible to Fusarium wilt disease with a field attack rate of 10 to 20%. The research was conducted to get a simple and can be done by farmers by using Plant Growth Promothing Rizobacteria (PGPR). Research was conducted in the laboratory to determine the biochemical characteristics of rizobacteria and in the greenhouse to determine the effect on plant growth. Tests conducted on three isolates of bacteria P. alcaligenes which is the result of previous research. The results showed that the rhizobacteria tested were gram negative bacteria, did not produce enzyme oxidase, produced catalase enzyme, glucose fermentation, lactose and sucrose, did not produce gas and cyanide acid. The three rizobacterial isolates are able to spur the growth of tomato plants through soaking the seeds with PGPR suspense for 20-30 minutes. Application of P. alcaligenes isolates has been shown to increase total phenol content up to 262% and 606% salicylic acid in tomato plant tissue. Soaking tomato seeds with P. alcaligenessuspense suppressed the tomato wilt disease 44.44 - 55.56% and were able to increase the yield of 3 to 4 times more than the control plants.
