Name of Technology: Weeding and herbicide management Technology for weed control of tossa jute fiber production.

Year of innovation: 2020

2.

Introduction: Weed management is a major cost for jute production. In jute weed control, Ethoxy sulfuron and Fenoxaprop-p-ethyl can be applied together to control mutha, small weeds, sedges, weeds, and 1 application after 20 days gives maximum yield at low cost.

3.

Salient features of the technology:

     ·         As many as 18 species of weeds occur in jute fields. Some of these weeds are very large and cause a lot of damage. Such as Mutha, Khude Shama, Anguligas, Fuska Begun, Fox Tail etc. A number of more harmful weeds can be controlled through the use of herbicides.

     ·          Ethoxy sulfuron and Fenoxaprop-p-ethyl can be applied together to control mutha, small weeds, ungulates, weeds and get high yield at low cost.

    ·         Weed management costs and labor hours are reduced through the use of herbicides.

      ·         Net profit in jute crop cultivation will increase

Brief description of technology:

The right herbicide should be applied in the jute field at the right time and at the right rate. Suppressed weeds: Mutha (Cyperus rotundus)

Chemical name: Ethoxy sulfuron (Sunrice 150WG) is effective if sprayed at the rate of 200 g/ha. At the time of spraying, it should be mixed with water as 50000 L/ha.

Suppressed weeds:

Khude shama (Echinochloa colonum)

Aunguli ghash (Digitaria sanguinalis)

Chemical name: Quizalofop-p-ethyl@ 650ml/ha. At the time of spraying, it should be mixed with water as 500 L/ha.

When the weed is 2-3 leaves old or within 10-15 days of sowing the jute seeds in the field, proper herbicides should be applied in a proper manner and at a moderate rate. But care should be taken that the plant does not have any wet condition or excessive heat of the sun.

1 day after application of Fenoxaprop-p-ethyl, Ethoxy sulfuron can be applied simultaneously to suppress mutha, small sedge, ungulate, weeds.

After 20 days after emergence of weeds, 1 nirani gives maximum yield at low cost

Suitability of the Technology: All over the country.

Economic benefit of the technology and role for livelihood development: Weed management is a major cost for jute production. By using herbicides to suppress jute weeds, by increasing jute production, jute exports will play an appropriate role in meeting the country's jute demand.
