A team from the Technical University of Munich (TUM) has developed a biodegradable agent that keeps pests at bay without poisoning them: like mosquito repellent used by bathers in the summer, biotechnologically produced cembratrienol deters voracious insects. If aphids have the choice between wheat seedlings with (right) and without CBT-ol treatment (left), they avoid the treated seedlings.
