**7.1. Chemical control**

Several fungicides have been tested against the *Fol* in different parts of the world. The study reveals that the systemic fungicides found to be superior to non-systemic fungicides in inhibiting the fungal mycelial growth in plates as well as in pot seed treatment. Benomyl (76.6%) showed the most positive results against the pathogen followed by thiophanate methyl (73.0%) whereas non-systemic fungicides viz. captan (67.8%) and dithane M-45 (62.3%) were the least efficient in reducing the fungal growth compared to the systemic fungicides [74]. On the other hand, Kasyap et al. (2008) has found much reduced fungal growth with captan (88.3%) [75]. Maheshwari et al. (2008) tested the effect of seven fungitoxicants against *Fol*. The results suggest that carbendazim was the most effective (5.6 mm) followed by captan (9.9 mm) and hexaconazole and diniconazole for reducing the fungal growth [76]. Several studies were carried out for determining the concentration of the fungicides to control the growth. The results suggest that the best fungus control was observed at highest fungicidal concentration (100 ppm) with benomyl followed by thiophanate methyl, second most effective at 100 ppm concentration [74, 77]. In Syria, seed treatment with benomyl-thiram did not affect Fusarium wilt incidence [78].
