Abstract
Fusarium wilt disease is one of the major problems in the production of tomato plant. Biological control by application Fluorescens Pseudomonads were hoped may control fusarium wilt disease. The aims of the study were to find out Fluorescent Pseudomonads combination were effective and efficient to control the fusarium wilt disease and increase plant growth on tomato plant. The study was carried out in the greenhouse KP. Laing Balittro Solok West Sumatera from October to December 2014. Treatments were arranged in a completed randomized design (CRD) with four replications. The treatments were combination of P. fluorescens PfT52 tomato- PfN147 patchouli plant and PfK21 rubber plant The results showed that P. fluorescens may decreased the development of the fusarium wilt disease and increased the plant growth tomato. The combination of Fluorecsens Pseudomonad PfT52- PfN147 and PfK21 were better and effective to control fusarium wilt disease with the incubated periode of disease symptom were 4.13 - 7.30 Day After Inoculation (DAI) and disease intencity were 14.30 - 40.24 %, disease efication were 0 % - 25,94 %, died plant number were 25.05 % - 84.40 %, and increase the tomato plant growth with plant height were 13.75 - 45,25 cm- and total leaves number were 7.25 - 12.50 leaves/plants- total twigs number were 2.50 - 4.75 twigs/plant- plant wet weight were 30.56 - 52.68 g/plant and plant dry weight were 3.56 - 7.08 g/plant.
