Management of foot and root rot disease of fennel

Abstract

This study was conducted at Spices Research Centre, BARI, Shibganj, Bogura, Bangladesh during Rabi season of 2018-2019 to find out the suitable control measures in controlling foot and root rot disease of fennel (Foeniculum vulgare Mill.).. Four fungicides, turmeric powder, poultry refuse and one control were the treatment. Foot and root rot incidence of fennel under different treatments ranged from 7.14-29.39%, while the lowest incidence was observed in seed treatment and soil drenching with Provax 200 WP (Carboxin + Thiram) at 0.25%, which was followed by Seed treatment and soil drenching with Autostin 50 WDG (Carbendazim) at 0.25%, and the highest foot and root rot incidence was observed in untreated control. Seed treatment and soil drenching with Provax 200 WP (Carboxin + Thiram) at 0.25% gave the highest number of seeds per plant (6588), weight of seeds per plant (20.57 g) and seed yield (2.01 t/ha) which was followed by seed treatment and soil drenching with Cabriotop (0.3%) and seed treatment and soil drenching with Autostin (Carbendazim) at 0.25%, and the lowest of these parameters were recorded in Control plots. So, farmers and researchers may Provax 200 WP (0.25%) or Autostin 50 WDG (0.25%) to decrease foot and root rot disease and increase seed yield of fennel.

Two cyanobacteria culture filtrates as potential biocides for controlling damping-off and root-rot diseases of fennel plants

“…Pre-and post-emergence damping-off were recorded 15 and 30 days after sowing, whereas the survived plants were assessed 45 days after sowing [16,5].…”

“…and Sclerotium rolfsii, stem-rot by Sclerotinia sclerotiorum) and Fusarium wilt (Fusarium oxysporum f.sp. funiculi) are the common and most serious diseases of fennel in Egypt and in the world [3,4,5]. Damping-off and root rot causes seeds, seedling death at early to late stage resulting in very poor plant stand which ultimately produces very low yield [6,7,5].…”

“…funiculi) are the common and most serious diseases of fennel in Egypt and in the world [3,4,5]. Damping-off and root rot causes seeds, seedling death at early to late stage resulting in very poor plant stand which ultimately produces very low yield [6,7,5]. High crop yield requires extensive use of chemical pesticides for protection against fungal pathogens and these chemical compounds may be phytotoxic to the plant.…”
