Abstract/ Executive Summary:

Pest status and Population fluctuation of red mite of Panikachu was studied and four different miticides were tested against this pest during kharif 2010. Mean no. of mite population per leaf was 10.33 in the heavily insecticide sprayed condition, while mite population per leaf was much higher (398.55) in the plots where no miticide was sprayed. In case of population fluctuation, the red mite population sharply increased from mid July to mid August then suddenly decreased up to mid September. All tested miticides gave more or less satisfactory reduction of mite population over control. However, Vertimec 018EC provided the highest percent of reduction (77.49%) of mite population over control.

Objectives:

To develop suitable control measure against red spider mite.

Methodology:

The experiment was conducted at TCRC, Bogra during Kharif 2010 to evaluate the efficacy of four insecticides against the red mite of panikachu. Seedling of BARI Panikachu-1 variety was transplanted in a plot of 5.4 m x 3.6 m having plant spacing of 60 cm x 45 cm. The experiment was laid out in RCBD having three replications and five treatments including control. The plot was fertilized with a dose of 275-180-225 kg/ha of Urea-TSP-MOP, respectively with 10t/ha of cow dung. Full dose of cow dung and TSP were applied at final plot preparation and Urea and MOP were applied as per plot wise. Other intercultural operations were done as and when necessary. Three sprays of miticides were done at 10 days interval. The treatments were as Vertimec 018 EC @1.2 ml/L of water, Kumulus DF @ 2 gm/L of water, Omite 57EC @ 1.2 ml/L of water, Dicofol 18.5EC @ 1.2 ml/L of water and untreated control. Incidence of pest status was estimated by recording data from 3 non-sprayed plots and 3 heavily miticides sprayed plots. Number of mite population were counted and recorded at 3 days and 7 days after 1st, 2nd and 3rd spraying. Data were recorded from single leaf randomly selected 5 plants/plot by direct observations with the help of magnifying glass. Yield data of panikachu (stolon) were recorded during each harvest.
