In this regard, Pak Ki Dok, a researcher of the college, told KCNA:

The immuno-agent helps promote germination, blossoming and fructification while building up resistance of vegetables and crops to drought and coldness. The agent has been introduced into greenhouse farming at different units, proving efficacious against different fungous and bacterial diseases.

When the agent is sprayed upon leaves of greenhouse vegetables, it takes the effect of restraining bacteria, deepening the color of vegetables and hastening their growth.
