Abstract/ Executive Summary:

A field experiment was conducted at TCRC, BARI, during cropping season of 2010-2011 to find out the effective weedicide(s) for the control of weeds. Comparatively higher yield was recorded from weedicide treated plots. Weed growth in the potato field was positively suppressed by weedicide Atom 70 WG and also by Sencor 70 WP. Through weedicide (Atom 70 WG and Sencor 70 WP) weeds like Boncopy and Khude shama can be successfully controlled. These chemicals showed positive impact over these weeds. It was also noticed that application of Atom 70 and Sencor 70 WP effectively controlled only broad leaf weeds, not the grasses like durba and mutha.

Keywords: Weedicides, Weeds, Potato

Location: Joydebpur, Gazipur.

Start Date: 27-11-2010

End Date: 27-02-2011

Program Area: Pest Management

Commodity: Potato

Objectives:

To find out effective weedicde(s) against weeds of potato.

Methodology:

A field experiment was conducted at TCRC field, Joydebpur, Gazipur, during cropping season, 2010-11. Different herbicides viz. Atom 70 WP, Topstar and Sensor 70 WP were used to findout the appropriate herbicide for potato field. Treatments were: T1-Control (only water) T2 - Atom 70 WG @ 0.50g/10 m² T3 - Atom 70 WG @ 0.75 g/10 m² T4 - Atom 70 WG @ 1.0 g/10m2 T5 - Top star 40 WP@ 0.3 g/10 m² T6 - Sencor 70 WP @ 0.5 g/l -1 T7 - Sencor 70 WP @ 0.75 g/ l^-1
