Integrated Management of Wilt Complex Disease of Chili (2015 - 2016)

M. R. HUMAUAN
RARS, Ishurdi, Pabna

Abstract/ Executive Summary:

The experiment was conducted at Regional Agricultural Research Station Ishurdi, Pabna during rabi season 2015-16 to find out effective management practices against wilt complex disease of chili. Eight treatments viz. T₁= Seedling treatment with Bavistin + Soil drenching with Bavistin @ 0.2%, T₂= Soil application with Stable Bleaching powder @ 20 kg/ha, T₃= Soil application with Calcium Nitrate @ 1% solution, T₄= Soil treatment with poultry litter (5t/ha), T₅=T₁+T₂+T₃, T₆= T₁+T₂+T₄, T₇= T₁+T₃+T₄, T₈= Control were tested for their performance against the disease. All the treatments showed significantly better performance over the control. Treatment T₇ performed the most satisfactory result by controlling wilt complex disease and increased yield than other treatments.

Keywords: Chilli, Wilt complex, Integrated Management

Location: The experiment was conducted at Regional Agricultural Research Station Ishurdi, Pabna

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Pest Management

Commodity: Diseases, Chilli

Objectives:

To develop an integrated management approach against wilt complex of chili.

Methodology:

The experiment was conducted at Regional Agricultural Research Station, Ishurdi, Pabna during rabi season 2015-16. The experimental land was well ploughed and properly leveled before bed preparation. Weeds and stubbles were removed from the field. Susceptible Chili variety BARI-Marich-3 was used in this experiment. The experiment was carried out following a randomized complete block design with three replications. The unit plot size was 3 m X 2 m and plant spacing was 40 cm x 40 cm. Seeds were sown on October 20, 2015, and transplanted in the main field on November 30, 2015. Eight treatments viz. T₁= Seedling treatment with Bavistin + Soil drenching with Bavistin @ 0.2%, T₂= Soil application with Stable Bleaching powder @ 20 kg/ha, T₃= Soil application with Calcium Nitrate @ 1% solution, T₄= Soil treatment with poultry litter (5t/ha), T₅=T₁+T₂+T₃, T₆= T₁+T₂+T₄, T₇= T₁+T₃+T₄, T₈= Control were used in this experiment. Recommended fertilizers were applied to raise a good crop. Intercultural operations were done in order to maintain the normal hygienic condition of the crop. The experiment was monitored regularly to observe the onset of wilt complex disease. The last harvest was completed on April 18, 2016. Data were recorded on disease incidence (%), plant height (cm), no. of fruit/plant, wt. of fruits/plant (g) and yield (kg/ha). 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)

Achievement/Findings:

Based on the above results it may be concluded that integration of seedling treatment with Bavistin + Soil drenching with Bavistin (0.2%) + Soil application with Calcium Nitrate (1% solution) + Soil treatment with poulty litter (5t/ha) is effective treatment for the management of wilt complex disease and yield increase of chili.
