Abstract
Methyl bromide (MB) was used for soil disinfestations more than 20 years in protected production areas, in Turkey.
The consumption peaked at 1319 tons in 1998. In the framework of Montreal Protocol, Turkey gradually reduced MB use for soil disinfestations starting from 2003. And its use was completely terminated at the end of 2007; in spite of the fact that Turkey was to phase out MB by 2015. MB alternatives such as solarization, grafting, soilless culture, chemicals and their combinations were introduced and successfully adopted in protected production areas.
This study was carried out in 2006-2007 production seasons in the Antalya Province.
Economic analysis of MB alternatives, solarization, grafting with different rootstocks, chemicals (metham sodium, dazomet and 1,3-dichloropropene) and their combinations were conducted.
The cost and benefit analysis of different alternatives based on experimental data were evaluated by using a partial budgeting method.
Climatical conditions of Mediterranean and Aegean costs in Turkey are very suitable for solarization in summer seasons especially for protected production.
Our results indicated that solarization alone or in combination with chemicals between June and September for 60 days provided very satisfactory outcomes.
In same group, effects of 1,3-D, metham sodium and dazomet on plant yields; however, their relative ease of application via drip irrigation promote the consumption.
Grafting can also be considered as an acceptable alternative to MB, because rootstocks provide better quality, higher yields and resistance and/or tolerance against soilborne pathogens.
