Abstract/ Executive Summary:

The experiment was conducted in the sick plot at Pulses Research Centre, BARI, Ishurdi, Pabna, Bangladesh during 2013-14 to find out the control measure of foot and root rot of lentil by seed treatment and its effect on yield. The test lentil variety was BARI Masur -1. Seven fungicides viz. Bavistin (0.2%), Tilt 250 EC (0.05%), Folicur EW 250 (0.1%), Indofil M 45 (0.2%), Ridomil gold (0.2%), Dithane M 45 (0.2%), and Vitavax 200 (0.2%), and one untreated control were used in this experiment. The lowest foot and root rot (20.65%), and the highest plant survival (79.35%) were obtained from Vitavax 200 (0.2%) followed by Bavistin (0.2%) and the highest foot and root rot (36.26%), and the lowest plant survival (63.74%) were obtained from control. The highest number of pods/plant, number of seeds/plant, weight of seeds/plant and yield (kg/ha) were recorded in Vitavax 200 (0.2%) which also followed by Bavistin (0.2%) and the lowest of these parameters were in untreated control.

End Date: 15-04-2014

Program Area: Pest Management

Commodity: Diseases, Lentil

Objectives:

To find out the control measure of foot and root rot of lentil through seed treatment and its effect on yield.

Methodology:

The experiment was conducted in the sick plot at Pulses Research Centre, BARI, Ishurdi, Pabna, Bangladesh during 2013-14. The experimental plot was prepared with five ploughings and cross ploughings followed by laddering to break the clods as well as level the soil. The weeds and stubbles of previous crops were collected and removed from the soil. Urea @ 50 kg/ha, TSP @ 90 kg/ha, MP @ 40 kg/ha and Boric acid 5 kg/ha were applied during final land preparation (Anonymous, 2011). The experiment was carried out following Randomized Complete Block Design with three replications. Size of the plots was 4.0 m × 1.6 m and plant spacing was 30 cm × continuous sowing. Seven seed treating fungicides and one control were used as treatment. The treatments were T₁=Bavistin (0.2%), T₂=Tilt 250 EC (0.05%), T₃=Folicur EW 250 (0.1%), T₄=Indofil M 45 (0.2%), T₅=Ridomil gold (0.2%), T₆=Dithane M 45 (0.2%), T₇=Vitavax 200 (0.2%) and T₈=Control (untreated). Lentil variety BARI Masur- 1 was used in the experiment. Seeds were treated with the fungicides and sown on November 13, 2013. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the field. The plots were inspected regularly to take observations on foot and root rot disease from seedling to maturity stage of the crop. Dead plants were counted and removed from the field. Disease plant parts were collected in laboratory for identifying foot and root rot causal pathogens. The crop was harvested on March 2, 2014. Data were recorded on foot and root rot, plant survival, shoot and root length at 30 DAS, plant height at harvest, number of pods/plant, number of seeds/plant, weight of seeds/plant and yield (kg/ha). The incidence of foot and root rot of lentil was recorded at every alternate day. The incidence of foot and root rot disease of lentil was calculated by the a formula.

The recorded data were analyzed statistically to find out the level of significance and the variations among the respective data were compared following Duncan’s New Multiple Range Test (DMRT) according to Gomez and Gomez (1984).

Achievement/Findings:

From the above study, it may be concluded that seed treatment with Vitavax 200 (0.2%) and Bavistin (0.2%) showed better performances for controlling foot and root rot disease of lentil with higher yield. So, farmers may use Vitavax 200 or Bavistin to control foot and root rot disease of lentil.
