Efficacy of Fungicides Against White Mold Disease of Mustard (2016 - 2017)

M. R. HUMAUAN
RARS, Ishurdi, Pabna

Abstract/ Executive Summary:

The experiment was conducted at the Regional Agricultural Research Station, Ishurdi, Pabna during Rabi season 2016-17 to find out the effectivity of fungicides for controlling white mould /Sclerotinia rot disease of mustard. Seven fungicides viz. Rovral 50 WP, Score 250 EC, Folicur 250 EC, Indofil M 45, Contaf 5 EC, Secure 600 WG and Tilt 250EC were tested for their performance against the disease. All the fungicides showed significantly better performance over control. The lowest incidence of white mould disease (2.63%) was found in Folicur 250 EC (2ml/l) treated plots whereas the highest (13.34%) was recorded in untreated control plots. Moreover, Folicur 250 EC (2ml/l) treated plots provided the highest yield (1.55t/ha).

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Pest Management

Commodity: Fungicide, Mustard

Objectives:

The present research work was undertaken to find out the effect of fungicides against white mould disease of mustard.

Methodology:

The efficacy of seven different fungicides was tested against white mould / Sclerotinia stem rot disease of mustard at RARS, Ishurdi, Pabna during Rabi season 2016-17. The experiment was laid out in a RCB design with three replications. The unit plot size was 3m x 3m. Seeds of BARI Sharisa-14 were sown on 12 November 2016. The spacing was 30 cm x 5 cm. Seven fungicides where, T₁= Rovral 50 WP (Iprodione) @ 2g/l, T₂= Score 250 EC (Difenoconazole) @ 2ml/l, T₃=Folicur 250 EC (Tebuconazole) @ 2ml/l, T₄=Indofil M 45 (Mancozeb) @ 2g/l, T₅ = Contaf 5 EC (Hexaconazole ) @ 2ml/l, T₆=Secure 600wg (Fenamidione + Mancozeb) @ 2g/l, T₇ =Tilt 250EC (Propiconazole) @ 1ml/l and T₈= Control were used in this experiment. The crop was allowed to grow under natural conditions and subjected to natural infection. Spraying was conducted three times at 7 days intervals starting from the immediate appearance of disease symptoms. Irrigation and other cultural practices were performed as and when necessary. Data were recorded on the incidence of white mould, plant population/m², plant height, number of siliqua/plant, and yield (t/ha). The data were analyzed statistically for tests of significance and mean compared following Duncan’s Multiple Range Test.

Achievement/Findings:

From the experimental results, it may be concluded that Folicur 250 EC (2 ml/l), Rovral 50 WP (2 g/l), and Tilt 250EC (1 ml/l) applied three times from the first appearance of the disease at an interval of 7 days found effective and economic in controlling of white mould disease and increase yield of mustard.
