Olive oil extract boosts pyrethroid potency

In simulated field experiments, plants sprayed with a mixture of SYN-A and lambda-cyhalothrin increased cabbage stem flea beetle (CSFB) mortality from 20% to 75% and reduced plant damage by at least 50% compared to lambda-cyhalothrin applications alone. Scientists at Rothamsted Research and ApresLabs Ltd have demonstrated that SYN-A, a naturally derived synergist extracted from olive oil, can restore the effectiveness of pyrethroid insecticides against CSFB, the most devastating autumn pest of oilseed rape. The research, published in Pest Management Science, reveals that combining SYN-A with the pyrethroid insecticide lambda-cyhalothrin increases pest mortality such that using just 20% of the standard…
