Abstract/ Executive Summary:

To find out effective fungicides against the disease a study was conducted at RARS Ishurdi, Panba during the month of March, 2004 to February 2005. The design of the experiment was RCBD having 3 replications. The unit plot size was 4m x 4m where 4 banana plants were grown with 2m x 2m spacing. The fungicides were (i) Tilt (0.05%) (ii) Folicur (.1%) (iii)Steel (.1%) (iv) Royal (.1%) (v) Fild (.1%) (vi) Edvestin (.1%) (vii) Propicon (.1%) (viii) Proven (.1%) (ix) Hayconazole (.1%) (x) Force (.1%) (xi) Dencozeb (.2%) (xii) Antracol (.2%) (xiii) Hydrocob(.2%) (xiv) and Pharzeb (.2%). Most of the fungicides significantly reduced the disease but Fild gave the highest disease control. The highest (8.28kg) total weight of fruit per plant was obtained in Dencozeb sprayed plot.

Program Area: Pest Management

Commodity: Fungicide

Objectives:

This study was under taken to find out effective fungicides against the disease.

Methodology:

The study was conducted at RARS Ishurdi, Panba during the month of March, 2004 to February 2005. The design of the experiment was RCBD having 3 replications. The unit plot size was 4m x 4m where 4 banana plants were grown with 2m x 2m spacing. Around every test plot there were 10 barrier plants. Fourteen different fungicides viz. (i) Tilt (0.05%) (ii) Folicur (.1%) (iii)Steel (.1%) (iv) Royal (.1%) (v) Fild (.1%) (vi) Edvestin (.1%) (vii) Propicon (.1%) (viii) Proven (.1%) (ix) Hayconazole (.1%) (x) Force (.1%) (xi) Dencozeb (.2%) (xii) Antracol (.2%) (xiii) Hydrocob(.2%) (xiv) Pharzeb (.2%) were tested in the trial. The fungicides were sprayed on 6 months old plants removing the older leaves keeping 7 new fresh leaves. The spray was conducted at 15 days interval and all together this treatment received 3 sprays. Disease data was recorded from the lower 7 leaves, two weeks after the last spray following standard scoring scale. Number of fruits per plant, average weight of single fruit and total weight of fruit per plant were recorded and statistically analyzed.

Achievement/Findings:

From the results it reveals that most of the fungicides significantly reduced the disease but lowest (46.03) PDI was in Fild which was identical with Steel, Proven, Royal, Tilt, Folicur and Edvestin. The highest number of fruits was obtained in Propicon (95.58) followed by Edvestin (91.08) but number of fruit of Edvestin, Propicon, Steel, Royal, Proven, Force, Hayconazole and also control was statistically similar. Although the average weight of fruit was insignificant the highest average weight of fruit (94.44g) was in Dencozeb sprayed plot and the lowest average wt. of fruit (64.18g) was Hayconazole sprayed plot. Significant difference was observed in cases of total weight of fruit per plant. The highest (8.28kg) total weight of fruit per plant was obtained in Dencozeb sprayed plot followed by Edvestin (7.94kg). The lowest (5.39kg) total weight of fruit per plant was obtained in Antracol treated plant which was statically identical with Hydrocob, Pharzeb, Control, Hayconazole, Fild, Folicur, Tilt and Steel treated plot.
