Plants have very sophisticated enemy detection systems. They need to be able to tell if they're being attacked by an aphid or caterpillar so that they can send out the right chemical signals to call for help. It's your job to mix up the perfect aromatic cocktail to attract the right kind of predator to deal with a very specific pest problem.
