The present research on
the effect of chemical inducers of systemic acquired resistance in sweet potato
(Ipomoea batatas Lam.) was developed during
2012-2013 at
Canete, Peru. The objective was to determine the effectiveness of some
chemicals used for the induction of systemic resistance on agronomic
performance of sweet potato
in order to improve overall health in the fields, increase of plant survival
and reduce the impact of agrochemical applications. Three sweet potato
genotypes were sown in RCBD with 3 replications during in the winter of 2012
and summer of 2013. Additionally two chemical inducers of SAR, potassium
phosphite (2.5 ml·L﹣1)
and acetylsalicylic acid (100 mg·L﹣1) were applied plus untreated
control plots. The results indicated that there were no statistical differences
(p > 0.05) for root weight·plant﹣1 or survival percentage and there were statistical
differences in weight of foliage·plant﹣1 for chemical treatments.
Statistical differences were found between seasons and interaction of seasons
and genotypes for foliage weight, suggesting a physiological effect by the
application of inducing systemic resistance chemicals on the agronomic
performance of sweet potato. It was concluded that specific effect of
acetylsalicylic acid increased the weight of foliage·plant﹣1 in
genotypes of sweet potato and there were no influences for root yield.
