Research

RESEARCH: The following aspects are covered by my research

1. Plant defence mechanisms - Oxylipins are likely signals in the early resistance response of
plants. The main objective is to identify oxygenated lipids (novel compounds) during the
early defence responses of wheat against the Russian wheat aphid.

2. Plant activators / extracts – The role of a) chitosan oligomers b) “Gliogrow” and
suspensions of the fungus, Trichoderma and c) other plant extracts to act as elicitors in
the defence and resistance mechanism of wheat against the Russian Wheat Aphid and
leaf rusts.

3. Repellent and insecticidal activity of plant extracts towards the Russian Wheat Aphid.

3. Influence of abiotic stress on chemical compounds and allelopathic properties of Amaranthus cruentus.
