Summary The botanical product RD‐Repelin® was highly repellent to pea aphids at concentrations of 1%, 4% or 10%. Repellency occurred prior to leaf contact by aphids at all three concentrations. RD‐Repelin® delayed symptom expression of zucchini yellow mosaic virus (ZYMV) in 81% of plants treated with 1% concentration, although virus transmission was not prevented. The effects of RD‐Repelin® on aphid settling behaviour, symptom expression and potential for pest management are discussed.
