“…However, the disease suppression McIntosh et al (28) achieved with CNB (50% scab surface reduction) was not found in our study (trial 1). The major benefit of using the di-substituted benzoic acids such as CNB was that yield and the shape of the tuber were not significantly affected (28), as was the case with the dichlorophenoxyacetic acids like 2,4-D (30,31). In our trials, deformation in tuber shape was not obvious following 2,4-D…”

“…The suppression of common scab symptom development by foliar auxin sprays has been previously demonstrated in a series of glasshouse and field trials (28)(29)(30)(31). McIntosh et al (29) had particular success with the phenoxyacetic acids 3,5-D and 2,4-D, reducing scab disease by 90 and 50%, respectively.…”

“…Some compounds show promising activity at very low dosages, without causing deformation of the tubers and/or distortion of foliage. In particular 2,5-dichlorobenzoic acid does not appear to affect scab as a downward-moving systemic bactericide, but to act by altering the response of the host to infection [Mclntosh et al, 1981[Mclntosh et al, , 1985[Mclntosh et al, , 1988. The modified host metabolism probably involves biosynthesis inhibition of phenolics, but not of terpenoids [Burrell, 1984].…”
