CASE STUDIES AND IMPLICATIONS OF CHEMICAL AND NON-CHEMICAL SOIL DISINFECTION METHODS IN TURKEY

This study was conducted in tomato crops grown greenhouses with a history of Fusarium wilt (Fusarium oxysporum f. sp. lycopersici) root rot (Rhizoctonia solani) and root knot nematodes (Meloidogyne incognita). The experiments were conducted in 2 greenhouses during the summer season of 2011 in Mersin province of the eastern Mediterranean region of Turkey.
Solarization in combination with reduced dosages of metam potassium (MP) (600, 800 L/ha) were tested against soil borne pathogens and nematodes.
The effect of different applications on disease incidence and galling index were determined in 2012.
Disease incidence reduction values were 50.80-54.60 and 74.98-76.50% in solarization alone and MP applied greenhouses, respectively.
The effect on disease incidence increased to 77.72-91.15% when solarization and MP (600-1000 L/ha) were combined.
Gall formation caused by root-knot nematodes in solarization and MP (1000 L/ha) alone, MP+solarization (600 L/ha) were 2.5-2.2, 0.3-0.4, 0.3-0.4, respectively.
Solarization in combination with reduced dosages of MP controlled root-knot nematodes until the end of the vegetation period.
