Economic Importance:

In greenhouse experiments, plant height, fresh and dry foliar weight, root weight, and total plant weight of maize were reduced significantly by T. zambiensis at the highest inoculum level (42 nematodes/cm-3 of soil).  At lower population levels, effects of Tylenchorhynchus zambiensis on maize growth were inconsistent. 

The highest final population (Pf) of T. zambiensis (Pf = 1,825,000 nematodes/pot) was obtained when Pi = 5,000 (4.0 nematodes/cm3 of soil).  The reproductive factor (R =  Pf/Pi) was 1184.0, 365.8, and 25.2, respectively for Pi = 500, 5,000, or 50,000 per pot. 

The authors conclude that T. zambiensis is a weak pathogen of maize.  (Study by Venditti and Noel, 1995).
