‘Cut Rootstock Method’ for Lanata Camara

Lanata Camara, an invasive weed has plagued 30% of Delhi’s ridge. To make way for native plants it needs to be eradicated. “Cut rootstock method has been suggested by ecologists and the forest department to control the further degradation at Asola Bhatti Wildlife sanctuary.

The weed has spread over a large part hence, obstructing the way for native plants. The “cut rootstock method”, however, takes a scientific approach and by making the growth dormant through a hormonal imbalance, it ensures that the lantana doesn’t germinate
It will be done by manually uprooting the weed and cutting its roots underneath the ground by an edge of 6-7 inches. The cycle additionally includes holding the evacuated plant upside down to kill it and removing the more modest lantana saplings, alongside the greater weed, physically. When the species is cleared, it permits the proliferation of the local bushes and creepers, which have frequently been viewed as immature or are attempting to develop normally close to the intrusive species. This method of weeding does not require any automated machine. The clearance of weed is to be expected by the end of this year.

Lantana suppresses native shrubs. It is spread by birds. There are approx 20 birds who eat the lantana seeds hence spreading the weed. The weed also produces a chemical that is volatile, preventing any insect to come near it. So, there is no pest on the plant. Cutting is of no use as it germinates if it is left on the ground.
