Abstract/ Executive Summary:

Efficacy of seven different treatments with poultry refuse (PR), mustard oilcake (MOC), Trichoderma harzianum based compost (TZ) and Furadan 5G alone, and application of three organic materials combined with Furadan 5G were tested for the management of root-knot (Meloidogyne incognita) of cucumber. The experiments were conducted during three consecutive years. All treatments considerably reduced root-knot severity and increased plant growth as well as yield. The highest reduction in root-knot severity was obtained with Furadan+MOC (81.33%) followed by Furadan+PR (76.52%), Furadan 5G alone (54.60), PR alone (67.89) and MOC alone (63.08). The maximum shoot growth was obtained with Furadan+MOC (41.38%) followed by Furadan+PR (38.87%), Furadan 5G alone (27.54) and PR alone (21.32). The highest yield increase was obtained with Furadan+MOC followed by Furadan+PR, Furadan 5G alone, MOC alone, PR alone, Furadan 5G+TZ and TZ alone. The treatments gave 127.98, 103.40, 64.47, 43.06, 33.09, 27.00 and 22.62% yield increase over control, respectively. Considering control of root-knot and increase in plant growth and yield, the treatments, Furadan 5G+ mustard oilcake, Furadan 5G+ poultry refuse and Furadan alone may be recommended for the control of the disease..

Program Area: Pest Management

Commodity: Cucumber

Objectives:

To evaluate the efficacy of three organic amendments and a nematicide applied in different combinations in an integrated management approaches against root-knot nematode of cucumber.

Methodology:

The nematicide was Furadan 5 g and the organic amendments were Poultry refuse (PR), Mustard oilcake (MOC) and Trichoderma harzianum (TZ). The materials were applied @ 45 kg, and 10 ton, 800 kg, 10 ton per hectare, respectively in 7 different combinations representing 7 treatments. The treatments were Poultry refuse alone , Mustard oilcake alone Furadan 5G alone, Trichoderma harzianum alone, Furadan 5G + PR, Furadan 5G + MOC, and Furadan 5G + TZ. An additional treatment was maintained where no materials were applied, which served as control. In case of combined application, PR, MOC, Furadan 5G and TZ based compost were applied @ 5 ton/ha, 400 kg/ha, 22.5 kg/ha and 7 g/pits, respectively. The PR and MOC were incorporated with soil at 21 and 15 days, before transplanting of cucumber seedlings. Whereas Furadan 5 G and T. harzianum were added to the soil at the time of transplanting. The experiment was conducted under field conditions during three consecutive years (2008-2010) in the research farm of BARI, Joydebpur, Gazipur. Unit plot size was 3 m x 2.5 m. Four pits were dig out in each plot and 21 days old healthy cucumber seedlings of a local variety were transplanted in the pit at two seedlings per pit. There were 8 seedlings per plots. The experiment was laid out in a randomized complete block design with three replications. After establishment of seedlings, severely galled roots of cucumber were collected from a sick bed of nematode and were chopped into small pieces. Two grams of chopped roots was incorporated with soils near the base of transplanted seedling. Irrigation and intercultural operation were done as and when necessary. The plants were allowed to grow for 20 days. At the end of the growing period, 50% plants were uprooted from the field carefully to minimize the damage of roots. The root systems were washed under running tap water and data on length and weight of shoot and root were recorded. The number of galls per gram of roots and yield contributing characters were also recorded. The degree of root galling was indexed on a 0-10 scale (Zeck 1971), where 0 represented roots free from gall and 10 represents severely galled root system. The data were analyzed statistically for ANOVA and means were compared following Duncan’s Multiple Range Test.

Achievement/Findings:

All treatments considerably reduced root-knot severity and increased plant growth as well as yield. The highest reduction in root-knot severity was obtained with Furadan+MOC (81.33%) followed by Furadan+PR (76.52%), Furadan 5G alone (54.60), PR alone (67.89) and MOC alone (63.08). The maximum shoot growth was obtained with Furadan+MOC (41.38%) followed by Furadan+PR (38.87%), Furadan 5G alone (27.54) and PR alone (21.32). The highest yield increase was obtained with Furadan+MOC followed by Furadan+PR, Furadan 5G alone, MOC alone, PR alone, Furadan 5G+TZ and TZ alone. The treatments gave 127.98, 103.40, 64.47, 43.06, 33.09, 27.00 and 22.62% yield increase over control, respectively. Considering control of root-knot and increase in plant growth and yield, the treatments, Furadan 5G+ mustard oilcake, Furadan 5G+ poultry refuse and Furadan alone may be recommended for the control of the disease.
