Abstract/ Executive Summary:

The experiment was conducted at the TCRC, Joydebpur during the period of 2009-10 to identify the effective herbicide and it is dose for controlling potato weeds. The experiment was consisted with ten treatments viz. three levels of Tostar 80WP (0.3, 0.2, 0.1 gl-1), three levels of Sencor 70 WP (1.5, 1.0 and 0.5 gl-1) and three levels of Magzin 70 WG (0.5, 1.0 and 1.5 gl-1) and control. Topstar 80WP @ 0.3 gl-1 was found to be better in controlling weed as well as getting better yield of potato in comparison to Magzin 70 WG and Sencor 70 WP.

Keywords: Herbicides, Controllng, potato Grass, Broad Leaf Weeds

Location: Joydebpur, Gazipur.

Start Date: 26-11-2009

End Date: 26-02-2010

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To identify the effective dose of pre_emergence herbicide for controlling potato weeds.

Methodology:

The experiment was conducted at the TCRC, Joydebpur during the period of 2009-10. The experiment was consisted with ten treatments: T1 (Topstar 80 WP 0.3 g l-1), T2 (Topstar 80 WP 0.2 G l-1), T3 (Topstar 80 WP 0.1 G l-1), T4 (Sencor 70 WP 1.5 g l-1), T5 (Sencor 70 WP 1 l-1), T6 (Sencor 70 WP 0.5 g l-1), T7 (Magzin 70 WG 0.5 g l-1), T8 (Magzin 70 WG 1 l-1), T9 (Magzin 70 WG 1.5 g l-1) and T10 (Control).All the doses were applied after seven days of tuber planting. Data on weed were recorded before spraying (weed population), after spraying (Spotted and yellow leaves) and before harvesting (Fresh and dry weight of weed) of the potato. The crop was harvested at 80 days after planting. Yield contributing parameters of potato were recorded at 60 DAP and 80 DAP. Collected data were analyzed statistically and means were separated by using DMRT.

Funding Source:

1. Government

Budget: 20,000/=

Total Budget (Tk.) : 20,000/=

Achievement/Findings:

Topstar 0.3 gl^-1 was found to be better in controlling weed as well as getting better yield of potato in comparison to Magzin 70 WG and Sencor 70 WP. Weed injured in initial stage of spraying but in latter weed was recovered. So in narrow leaf like Cyperus rotundus, Imperata cylindrica, Cynodon dacrylon these herbicides are not effective.
