Jasmonic acid (JA) is a naturally occurring, non-toxic chemical which can be used as an environmentally benign pesticide applied as seed treatment resulting in long lasting protection against herbivorous pests. In tests seeds from tomato, sweet pepper, wheat and maize were treated with JA and plants grown from these seeds were subsequently challenged with a range of pests (caterpillars, aphids and spider mite). The effect of the treatment were reduced feeding and reductions in pest population and reproductive rates.
