ABSTRACT
The studies on the control of Fusarium wilt of tomato was carried out in Girei Local Government Area Adamawa State. Using treatments combinations consisted of three levels each of jatropha, neem and tamarin ash assigned in Completely Randomized Design (CRD), replicated four times. Data collected was analysed using Statistical tool for Applied Sciences (SAS) and means that were significantly different were separated using the Least Significant Difference (LSD). Results of in-vitro control trials indicated that there were significant differences (P < 0.05) among the treatments with respect to the control of the Fusarium oxysporum. Jatropha leaf extracts produced the inhibition zone of 37.50%; neem gave 32.53% while ash had 24.86% inhibition. Concentration levels of 2.0 ml, 1.5 ml, and 1.0ml/20 ml of PDA were also significantly different, with increased efficacy as concentration of treatment increases. For in-vivo trial, the treatments were significantly different (P < 0.05) from the control, reducing the disease of tomato seedlings. Concentration of 3.0 ml/kg, 5.0 ml/kg and 10 ml/kg were also significantly different at P < 0.05, with increased efficacy as concentration of treatment increases. From the in-vitro findings and screen house study, jatropha leaf extracts gave the best control of the pathogen and produced the highest seedling growth followed by neem leaf extracts and ash whereas increase in concentration increases the control of the pathogen, therefore farmers are recommended to use jatropha at 5.0ml/kg.
