Abstract/ Executive Summary:

A field experiment was carried out at Regional Pulses Research Station (RPRS), Madaripur during Rabi season of 2015-16 to select effective fungicide in controlling Stemphylium blight of lentil. Five different fungicides of different group viz. Rovral 50WP (Iprodione) (0?2%), Secure 600WG (Fenamidone+Mancozeb) @ 0.1%, Nativo 75WG (Tebuconazole+Trifloxystobin) (0?2%), Folicur 430SC (Tebuconazole) @ 0.1%, Nativo 75WG (Tebuconazole+Trifloxystobin) @ 0.2%+Folicur 430SC (Tebuconazole) @ 0.1% and one control were used. Results revealed that among the five fungicides, three times foliar spray with Rovral 50WP (Iprodione) (0.2%), and Nativo 75WG (Tebuconazole+Trifloxystobin)+Folicur 430SC (Tebuconazole), showed lowest stemphylium blight disease score (1.33) and highest (3.33) was in untreated control plot. The highest yield was obtained in Rovral 50WP (Iprodione) treated plot (1075 kg/ha) and increase of yield over control (66.66%) followed by Nativo 75WG (Tebuconazole+Trifloxystobin)+Folicur 430SC (Tebuconazole) (931 kg/ha) where increase of yield was 62.40% over control and lowest was in untreated control plot (350 kg/ha).

Location: A field experiment was carried out at Regional Pulses Research Station (RPRS), Madaripur during Rabi

Start Date: 00-00-2005

End Date: 00-00-2016

Program Area: Pest Management

Commodity: Fungicide, Lentil

Objectives:

There are many options to control the disease. Among the different alternate means of disease management. The objectives is to find out the effective control measures of the Stemphylium blight disease of lentil

Methodology:

The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Five fungicides and one control were used in this experiment. The fungicides were Rovral 50WP (Iprodione) (0.2%), Secure 600WG (Fenamidone+Mancozeb) @ 0.2%, Nativo 75WG (Tebuconazole+Trifloxystobin) (0.2%), Folicur 430SC (Tebuconazole) @0.2%, Nativo 75WG (Tebuconazole+Trifloxystobin)+Folicur 430SC (Tebuconazole) @ 0.2% and one control. The fungicides were selected through review of literature. The unit plot size was 5m x 4m with spacing of 30 cm x 05 cm. Stemphylium susceptible lentil variety BARI Masur-1 was sown in rows on 05 November, 2015. Intercultural operations were done as and when necessary. The experiment was monitored regularly to observe the onset of stemphylium blight disease. Spraying of fungicides was started when the disease appeared. Total three sprays were applied at an interval of 7 days with the knapsack sprayer. The spray date was 30 December, 2015, 07 January, 2016 and 14 January, 2016. Data on yield and yield contributing characters were taken from 10 randomly selected plants and stemphylium blight score were recorded on 0-5 scale. The crops were harvested after maturity. Grain yield (kg/ha) were recorded from the whole plot. The recorded data were analyzed statistically to find out the level of significance and the variations among the respective replications through MSTAT-C.

Achievement/Findings:

Result of fungicides in controlling incidence of stemphylium blight and yield contributing characteristics were recorded. The best Stemphylium disease score (1.33) was recorded in Rovral 50WP (Iprodione) and Nativo 75WG (Tebuconazole+Trifloxystobin)+Folicur 430SC (Tebuconazole) treated plot and the highest (3.33) in untreated control plot. These two treatments also increased the highest disease reduction (60.06%) over control. The lowest disease reduction (30.03%) achieved from Secure 600WG (Fenamidone+Mancozeb) and Nativo 75WG (Tebuconazole+Trifloxystobin) treated plot. Among the five fungicides Rovral 50WP (Iprodione) sprayed plot produced the highest seed yield (1075 kg/ha) and increased seed yield 66.66% over control followed by (931 kg/ha) in Nativo 75WG (Tebuconazole+Trifloxystobin)+Folicur 430SC (Tebuconazole) treated plot which increased yield 62.40% over control. The lowest yield (350 kg/ha) obtained in control plot. From the above study, it may be suggested that three times foliar spray with Rovral 50WP(Iprodione) @0.2% and Secure 600WG (Fenamidone+Mancozeb) (0.1%) at an interval of 7 days showed better performance to control incidence of stemphylium blight as these fungicides has given minimum score (1.33) and higher yield (1320 & 1180 kg/ha) of lentil. So, these two fungicides could be used at farmers’ field to control stemphylium blight of lentil.
