Incidence and Control of White Grubs in Poplar Nurseries at Nauni in Himachal Pradesh

Poplars are highly preferred and profitable agro-forestry trees propagated by planting entire transplants raised in nurseries. The plants in the nursery suffer damage by White grubs which feed on its ischolar_mains. In the experiment conducted to control the pest by using Phorate l0G and Chlorpyriphos in different concentrations , by administering them in two instalments , one at the time of planting and cuttings , and the other 2 months after that , it was found that Phorate l0G @ 20g/m² was more effective in controlling the pest , although Chlorpyriphos @ 2ml/lt and other concentrations were almost equally good , and resulted in better growth parameters i.e. height and collar diameter.
