ABSTRACT:

The effect of seed treatment with fungicidal antiseptics such as Topsin (Thiophanate-methyl 70%) and Rhizolix (Thiram 30% + tolcophos methyl 20%) was studied, for the control to Fusarium wilt disease caused by the fungus Fusarium oxysporum f.sp.cumini

During the agricultural season 2020-2021, the results showed that the use of fungal antiseptics Topsin (3g/kg seeds) in seed sterilization and spraying (1 g/liter of water) on the vegetation and soi and Rhizolix (3g/kg seeds) in seed sterilization and spraying (2 g/liter of water) on the vegetation and soil, reduced the infection rate to 2.15%.

 for Rhizolix  and 2.17% for Topsin in field conditions. It was also shown that the use of Topsin and Rhizolix  only by spraying on the total vegetative and soil after 20 and 40 days of germination reduced the infection rate to 11.86% and 14.46%, respectively. In Comparison to the control. The use of fungal antiseptics has also led to an increase in the number of branches/plants, root length/cm, plant height/cm, plant Length/cm, number of seeds/plants, weight seeds/plant/g, weight of 100 seeds/g, and productivity increase kg/ha, compared to the rest of the treatments.

Also, the use of fungal antiseptics led to a shorter total growth period, while the untreated plants in the control took more days to complete growth and reach the stage of physiological maturity and then harvest compared to the rest of the treatments.

Key words: Cuminum cyminum Ls, Fusarium oxysporum f.sp. cumini, Fungicides.
