Onion thrips on lettuce - monitoring infestations and investigating prospects for control

This study conducted by Crop & Food Research looks into the practicality of monitoring crops for thrips and thrips damage; compares the efficacy of the timing of insecticide spray applications in relation to the lifting of onions at topfall; and compares the impact of thrips infestation and control measures on small and large lettuce plants. This project confirmed that it is unwise to grow lettuce crops near onion crops in the summer – a few thrips can cause a lot of damage.
