Abstract/ Executive Summary:

The experiment was conducted at farmers’ field of BBC bazaar, Ishurdi, Pabna during 2012-13 to find out the effective management practice against different diseases of ber as an eco-friendly manner. Twelve treatments were tested against the diseases. All the treatments showed significant effect over control. The incidence of spotted fruit of ber ranged from 1.11 – 6.18 %, where the highest incidence was recorded in control and the lowest was in alternate spray of Thiovit+ Mustard oil+ Tilt .The lowest incidence of rotted fruit 1.03 % was recorded in Thiovit @3g L^-1 of water treated plot and the highest (5.05 %) was recorded in control. The highest yield of fruit (88.60 kg plant^-1) was recorded in alternate spray of Thiovit+ Mustard oil+ Tilt treated plot and the lowest (60.4 kg plant^-1) was recorded in control treated plot.

Objectives:

To search alternate options to control important ber diseases in an eco-friendly manner.

Methodology:

The experiment was conducted at framer’s field of BBC bazaar, Ishurdi, Pabna during 2012-13. Weeds and stubbles were removed from the field. The experiment was carried out following Randomized Complete Block Design with three replications. Plant to plant distance 2.75m and row to row distance was 2.75m. The test variety of ber was BAU kul. Twelve treatments were T₁= Thiovit @3g L^-1 water, T₂= Tilt @0.5ml L^-1 water ,T₃= Neem oil @5ml L^-1 water+ Trix @5ml L^-1 water, T₄ = Mustard oil @5ml L^-1 of water+ Trix @5ml L^-1 of water, T₅= Sodium bicarbonate @1g L^-1 water, T₆=Detergent (Trix) @1 table spoon/4.5L of water, T₇=Alternate spray of Thiovit+ Neem oil+ Tilt, T₈=Alternate spray of Thiovit+ Mustard oil+ Tilt, T₉=Alternate spray of Thiovit+ Sodium bicarbonate+Tilt, T₁₀=Alternate spray of Thiovit+ Neem oil+Tilt+Mustard oil+Detergent+Sodium bicarbonate, T₁₁=Ripcord10EC @1ml L^-1 water and T₁₂=Control. Spray was started before 15 days of flowering and continued upto 7 days before harvest and spray interval was 15 days. Fertilizers and manures were applied as per recommendation. Two year’s aged ber orchard was selected in this experiment. Data were recorded on disease Incidence of spotted fruit, Incidence of rotted fruit, number of fruits plant^-1) and Yield.. The recorded data were analyzed statistically following Duncan’s New Multiple Range Test (DMRT).

Achievement/Findings:

The incidence of spotted fruit of ber ranged from 1.11– 6.18%, where the highest incidence was recorded in control and the lowest in alternate spray of Thiovit+ Mustard oil+ Tilt. The lowest incidence of rotted fruit 1.03% was recorded in Thiovit treated plot and the highest (5.05%) was recorded in control. The highest yield of fruit (88.60 kg plant^-1) was recorded in alternate spray of Thiovit + Mustard oil + Tilt treated plot and the lowest (60.40 kg plant^-1) was recorded in control treated plot.
