Summary

Three biofertilizers (BF) and three plant strengtheners (PS) were tested in comparison
to chemical fertilizer application and BABA (DL-3-amino-n-butanoic acid), respectively
for their effects on the reactions of six different tomato varieties against three isolates
of Phytophthora infestans in detached leaf disk assays. All experiments were repeated
twice with six replicates each. Two of the BF (BioIlsa and Biofeed Quality) significantly
reduced late blight severity as compared to horn meal and chemical fertilizer with no
fertilizer by isolate and fertilizer by variety interactions. All PS significantly reduced
susceptibility of all tomato varieties. However, the interactions among PS, variety and
isolates were highly significant suggesting that different resistance mechanisms might
be affected by the PS and BABA. Preliminary results indicate that the combined
effects of PS and BF are additive without interactions.
