What is the correct hpm dhavak dosage?

The recommended dosage is 1 litre per acre or 200 ml in 20 litres water.

Is glufosinate ammonium herbicide safe for soil?

Yes, it has lower residual toxicity than many other chemical herbicides.

HPM Dhavak is a non-selective, post-emergence weed killer formulated with glufosinate ammonium 13.5 SL. It provides fast and reliable control of annual and perennial weeds, including broadleaf, grassy weeds, and sedges. Dhavak works through contact action—absorbed by the leaf surface, it inhibits glutamine synthetase, causing ammonia buildup that disrupts photosynthesis and leads to rapid weed death.

This glufosinate herbicide is effective even under cloudy weather or low sunlight conditions, offering flexibility in field applications. Farmers use it widely in cotton, tea plantations, and non-crop areas for maintaining weed-free fields. With lower soil residual toxicity compared to other chemicals, glufosinate ammonium herbicide supports sustainable farm practices.
