Abstract
Broomrapes (Orobanche spp.) which belong to the family Orobanchaceae are obligate parasitic flowering plants.
Some particularly damaging Orobanche spp. occur in the Antalya Highlands region in Turkey, causing important damage to tomato crops.
Controlling these parasitic plants is difficult because broomrapes produce hundreds of thousands of minute seeds that are highly persistent in the soil and can easily spread to new areas.
Moreover, due to the intimate connection between these holoparasitic weeds and their hosts, no economically viable and effective control system against the parasites has been developed in tomatoes, which contributes to the continuously increasing importance of these weeds in agricultural areas.
The soil treatment dimethyl disulfide (DMDS) has been successful in controlling nematodes, and other soil-borne pathogens occurring along with nematodes in different crops, and several weed species, in particular Cyperus spp.
Dimethyl disulfide has been recently approved in Turkey for Orobanche spp. control.
One study was carried out under compliance with good experimental practices with randomization and four replicates.
Dimethyl disulfide was applied by drip irrigation under barrier film in protected tomatoes.
This product was tested at three doses in comparison with untreated plot and local reference.
Assessments showed a broomrape infestation of 100% in untreated and reference plots, while plots treated with the highest dose of DMDS showed no infestation.
