| 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... |

| Three winter wheat composite cross (CC) populations were created in 2001 in the UK consisting either of 20 modern wheat parents (called A Population), a subset of 12 high quality parents (Q), or a subset of 9 high yielding parents (Y). Seed of the F4 was transferred to the University of Kassel in 2005 and the populations were grown since then under organic and conventional conditions in well separated large (>100m2) plots in two parallel sets (12 populations total) without conscious selection applied. In the conventional system fungicides and insecticides were not applied to expose the populations to natural pest and disease pressure. Morphological diversity, diseases, and yield were assessed in the field every season. The parents and a total of... |

| There are numerous instances in which induced plant resistance responses (IR) have been demonstrated. However, before IR can be made use of in practice it is important to understand as much as possible the ecology and genetics of the inducing agents and their interactions with plants and pathogens. Effects of host genetic background were tested with thirteen tomato varieties and two isolates of Phytophthora infestans. Isolate effects on inducibility were tested with six varieties and six pathogen isolates. Leaf disks of plants that had been treated with BABA (DL-3-aminobutyric acid) or water were inoculated seven days later with 20 µl sporangial solutions of 5*104 sporangia ml-1. All experiments were repeated three times with six replications each.... |
