1. harmful

   Pernicious (Latin per, through, and neco, kill) signifies having the power of destroying or injuring, tending to hurt or kill. Pernicious is stronger than injurious; that which is injurious is capable of doing harm; that which is pernicious is likely to be destructive. Noxious (Latin noceo, hurt) is a stronger word than noisome, as referring to that which is injurious or destructive. Noisome now always denotes that which is extremely disagreeable or disgusting, especially to the sense of smell; as, the noisome stench proclaimed the presence of noxious gases.

   This technology enables the next generation of 'agri-chemicals' to be used. So a lot of existing chemicals are perhaps coming to the point where they're going to be banned. The next generation, they're typically called 'biologicals', they're very much more expensive than the chemicals used today. This technology, however, might be an enabler for them. So you have something that's a little bit more targeted and a little bit more environmentally friendly that can do the same jobs as a lot of the more harmful chemicals do today.
