In Kenya Louise Labuschagne develops bugs rather than pesticides to deal with plant problems. Anna Hill meets her in Rutland to discuss the pros and cons of biocontrols with two local farmers, Andrew Brown and Robert Symington.

Louise made her mark recently at the Oxford Farming Conference when she intervened in a disagreement between environmental campaigner George Monbiot and David Caffall, head of the trade organisation that represents pesticide manufacturers, the Agricultural Industries Confederation. She tells Anna how and why she thinks that pesticide use can be reduced with the judicious use of biocontrols, but that they're far from being mutually exclusive.
