Integrated strategy to control wilt disease of cumin (Cuminum cyminum L.) caused by Fusarium oxysporum f. sp. cumini (Schlecht) Prasad & Patel

Abstract

Various fungicides, oilcakes and fertilizers were evaluated at Jaipur (Rajasthan) for themanagement of cumin (Cuminum cyminum) wilt caused by Fusarium oxysporum f. sp.  cumini.Trimethyl thiuram disulphide (0.1 g g-1 seeds) was the best fungicide which was on par withpropiconazole, carbendazim and copper oxychloride (0.1 g g-1 seeds) for the control of wilt.The disease incidence was minimum under the soil treatment with neem cake (30 q ha-1)which was on par with sesamum cake (25 q ha-1). Among the chemical and non-chemicalmanures, application of NPK @ 40 kg ha-1 was most suitable to control the disease whichwas on par with Azotobacter @ 40 kg ha-1. The disease incidence was also significantly lowerin plants grown in solarized soil. The yield was significantly higher in all treatments ascompared to control. The highest cost : benefit ratio was obtained (1:40) in thiophanatemethyl treatment followed by carbendazim. Among the combined treatments, minimumdisease incidence was recorded with solarized soil + sesamum cake @ 25 q ha-1 + seed treatmentwith carbendazim @ 0.1 g g-1 seeds followed by solarized  soil + sesamum cake @ 25 q ha-1  +Azotobacter @ 40 q ha-1. However, the highest  cost : benefit ratio (1:10.6) was obtained withsolarized soil + sesamum cake @ 25 q ha-1 + Azotobacter (biofertilizer) @ 40 kg ha-1. Theintegrated treatments recorded the highest grain yield and low disease incidence over controlas compared to individual application.
