The aim of this study was to develop an in situ, non-destructive method for observation and monitoring of the underground developmental stages of the root parasite Orobanche cumana. The parasitic weed Orobanche causes severe damage to vegetables and field crops. Most of the damage occurs during the underground, unobservable parasitism stage. Sunflower (Helianthus annuus cv. Adi) plants were planted in a soil that was artificially inoculated with O. cumana seeds. Clear Plexiglas minirhizotron observation tubes were inserted into the soil. Seed germination, early stage of penetration, and formation of tubercles and spikes were observed non-destructively and were monitored as video images throughout the growing season by means of a minirhizotron TV camera. Use of this technology enabled monitoring the complete individual parasite life cycle, from germination to shoot emergence. In addition, the effect of the systemic herbicide imazapic on the development of O. cumana was inspected and quantified. This novel methodology facilitates the in situ study of major aspects of the host-parasite interaction, parasitism dynamics, parasite growth rate and the effect of chemical treatments on the parasite.
