Control measures of weed in wheat fields

Control measures

  1. The weeds can be controlled either manually or through the use of herbicides/weedicides. One hoeing after about a month would keep the weeds under control and provides aeration to the developing root. Closer planting and cross sowing was also found effective to reduce these weeds. Because wheat is grown on a very large acreage, it is not possible to control the weeds with manual labour
  2. Use of herbicides/weedicides

(A) Broad leaf weeds: Bathua, Satyanashi, Krishnneel, Gazari, Piazi etc.

  • Weedicide: Spray of 2,4-D sodium salt 80 WP @ 625 g/ha

Application method: Prepare the solution in ~ 800-1000 litre of water and apply with flatfan nozzle sprayer after 30-35 days of sowing.

(B) Narrow leaf weeds: Gehusa/Gullidanda(Phalaris minor) and wild oat

     Weedicides and their recommended quantity:

  • Isoproturon 50%@ 1.5 kg/ha. Or
  • Isoproturon 75%@ 1 kg/ha. Or
  • Sulfosulfuron 25g a.i./ha. Or
  • Pendamethylene 30EC @3.30  litre/ha (pre-emergence) 

Time and method of herbicide application:  Prepare the solution in ~ 800-1000 litres of water and apply with flatfan nozzle sprayer after 30-35 days of sowing @ per hectare. In case there is problem of broad and narrow leaves weeds at the same time apply 2,4-d along with isoproturon.
