Head of agronomy department Dr MS Bhullar observed, “In general, post-emergence herbicides applied after the first irrigation are used for its control. However, the weed has evolved resistance to post-emergence herbicides used for its control, especially in fields where the same herbicide is applied year after year, which makes its control difficult in wheat fields. Under these situations, the use of pre-emergence herbicide is more beneficial as these herbicides prevent the germination of gulli-danda.”

Further, Bhullar recommended the application of any of the pre-emergence herbicides like Stomp/Bunker/Dost 30 EC (pendimethalin) @ 1.5 litre; Awkira/ Momiji 85 WG (pyroxasulfone) @ 60 g; Platform 385 SE (pendimethalin + metribuzin) @ 1.0 litre; or Dakshplus 48 EC (pendimethalin + metribuzin) @ 900 ml/acre, immediately after sowing, but in all cases within two days of sowing. “Use 200 litres of water/acre and flood jet/flat fan nozzle for spray of pre-emergence herbicides. Prefer use of Lucky Seed Drill which sows wheat and sprays herbicide simultaneously,” he advised.

The herbicides provided best weed control when sprayed uniformly in a well-prepared moist field, free from clouds, as herbicides needed moisture for activation, he said.

Elaborating, he suggested alternate use of non-chemical methods of the control of weed gulli-danda. Dr Bhullar cited an example of surface seeding-cum-mulching technique of wheat sowing that provided effective control of gulli-danda and other weeds, as the field was completely covered with paddy straw mulch which prevented germination and emergence of weeds. Similarly, wheat sown using Happy Seeder, in standing paddy stubbles, would have lower weeds, he informed. “So in fields having history of gulli-danda, the solution lies in the use of any of the above-mentioned pre-emergence herbicides or the sowing of wheat by Surface Seeding-cum-Mulching technique or by using Happy Seeder,” he advised.
