The Punjab agriculture department has started a campaign to motivate farmers to adopt proper methods to spray weedicides to ensure efficient control of weeds in wheat crop across the state.

Agriculture experts say that the success of chemical weed control depends mainly upon the quality of herbicides and the spraying technology.

Weeds could lead to loss in the yield of wheat from 20 to 40%. Therefore, timely measures are needed to mitigate the loss. Suitable herbicides should be applied in consultation with the experts of the agriculture department after first irrigation on broad leaf as well as narrow leaf weeds for effective control by adopting proper spray techniques.

State award winner agriculture development officer (ADO) of Moga Dr Jaswinder Singh Brar, who has carried out demonstrations of spraying techniques at the government seed farm in Raunta village in the district, said that a majority of the farmers were unaware of the proper weedicide spraying techniques.

"Application techniques are most important in the management of Phalaris minor (gulli-danda) as proper spray pump nozzles, volume of water and optimum dose and the time of spray along with uniform coverage certainly help in better control of the weed," said the ADO.

He said that most of the farmers did not have proper nozzles fixed to their spray pumps, which did not give proper results. "I recommend the farmers to use flood jet and flat fan nozzles for uniform spray of weedicies on the weeds and never use cone type nozzles for spraying weedicides to get good results, spray should be done in a straight strip, the nozzle should not be moved away from the strip and it should be kept 40 to 50 cm above the crop for effective control of weeds," said the ADO.

Experts also suggest that the farmers should use flat fan or flood jet nozzle for herbicides spray at noon during the bright sunny days after evaporation of dew from the plant surface. The water mixture used for herbicides spray should be 80 to 100 litres per acre. The whole field must be sprayed uniformly and no spot should be sprayed twice to harvest the bumper wheat crop.

"Farmers should also use recommended good quality herbicides and adopt proper spray technique/ schedule recommended by Punjab Agricultural University or the agriculture department. After spray, the first and second irrigation should be very light, flood or heavy irrigation reduces the effect of herbicides," said experts.

Punjab agriculture minister Tota Singh said that the department of agriculture motivates the farmers for adoption of improved technology along with improved agronomic strategies, which will help in enhancing the productivity of the crops. "Farmers should adopt new technologies as recommended by experts for the control of weeds as well as to save natural resources," said Tota SIngh.
