Abstract
Methyl bromide was an essential soil fumigant for good vegetable production in Egypt.
It was applied as a pre-planting fumigant for controlling fungal pathogens, root-knot nematodes and weeds in most vegetables such as cantaloupe, cucumber, lettuce, pepper, strawberry and tomato.
Following decisions of the Montreal Protocol regarding the MB phase-out, the Agricultural Research Center selected alternatives in order to replace MB. Dimethyl disulfide (DMDS) has been tested recently in Egypt.
The greenhouse experiments were carried out in boxes of 1 m2 during two successive seasons of 2012/2013 in the unit of Identification of Microorganisms and Biological Control (BRCS) Plant Pathology Research Institute, ARC, Giza, Egypt to evaluate the efficacy of different concentrations of DMDS as methyl bromide alternative combined with virtually impermeable film and polyethylene plastic film for controlling the major soil borne, root-knot nematode and weeds on pepper, cucumber and tomato.
These experiments evidently support the MB phase-out but need to be part of a wider approach, including registration and commercial availability of this alternative.
