Effect of Healthy and Nematode Infested Planting Materials in Controlling Nematode Diseases of Banana in Virgin Soils

M.I.Faruk
Former SSO
Plant Pathology Division, BARI, Gazipur

Abstract/ Executive Summary:

Hot water treated plants were least affected by the nematodes. % disease infection or portion of roots to be damaged by nematodes was influenced significantly by the treatments. Highest gall index and damaged roots had been resulted from the control plots, where the suckers were not treated with either hot water or paring.

Keywords: Healthy and nematode infested planting materials, Nematode diseases, Virgin soils

Location: HRC, BARI, Gazipur

Start Date: 00-00-2002

End Date: 00-00-2003

Program Area: Pest Management

Commodity: Banana

Objectives:

To see the effect of healthy and nematode infested planting materials in controlling nematode diseases of banana in virgin soil

Methodology:

This experiment was conducted at the fruit orchard of HRC of BARI at Joydebpur, Gazipur, during 2002-2003. The plots was selected where banana was not planted more than 5 years. The experimental design was RCBD with 4 treatments and three replications. The treatments were i) hot water treated suckers, ii) Paring suckers, iii) tissue cultured seedlings and iv) normal suckers as control. Uniform sized banana suckers, cv. Amrit Sagor were used. The cleaned suckers were submerged for 20 min at 55⁰C in a hot water bath to get hot water treated suckers. All the roots were removed and the black spotter portions from corms were carefully removed from the suckers for paring. The tissue cultured seedlings were received from BRAC tissue culture laboratory, Joydebpur, Gazipur. The unit plot size was 2 x 2 m. Four plants were planted in each plot.

Achievement/Findings:

Results appeared that Hot water treatment and paring had significant effect of the percent root damage and gall indices by root-knot nematodes. The treatments had no significant effects o the plant height, plant diameter and root length of the banana plants. However, % disease infection or portion of roots to be damaged by nematodes was influenced significantly by the treatments. Highest gall index and damaged roots were resulted from the control plots, where the suckers were not treated with either hot water or paring. Hot water treated plants were least affected by the nematodes.
