The soil samples were taken to the Agricultural Research Council Nematology unit for evaluation.
The usual nematodes that are normally a problem to potatoes were counted in a 250 cc soil sample.
The trials were conducted by the research department of S.A. Golden leaf, a tobacco marketing and extension company.
Various treatments with combinations were done as an IPM (Integrated Pest Management) program.
Plants were removed and root evaluations were done. Various ratings were given according to the condition of the roots and nematode galls.
PURPOSE OF TRIAL
- Compare nematode count between trial and control
- Take 3 sample by planting season
- Compare yield between trial and control
- Compare costs of trial and control
Application of MOS Nema (25 lt/ha) was applied August 2004.
Only one application of MOS Nema was done.
Soils were re-sampled in November 2004 , April 2005 and October 2006.

To compare the effect Mos with standard nematicides (aldicarb)
To compare a range of rates
To test the product Mos in ratoon sugarcane
To evaluate the product Mos as a standalone product and in combination with CMS
To establish whether there are any residual effect from one year to the next.
During 2016 trials were initiated at a Cape Span farm.
Pratylenchus nematodes are the biggest problem.
Two treatments were applied 20l/ha Mos Nema and 12 kg/ha Fulvic Acid(72%). The first in September and then again in December 2016.
The control treatment was the standard chemical treatment used on apples, also two applications Nema trials at Villiersdorp, Western Cape.
