Results
Conclusions
It is concluded that the nematode control of FENDER™ is very good at 90 days after product application.
Evaluations: 90 days decrease of Meloidogyne population from 40 to 70% in 2.5 years old and 20 years old plants.
In both washed root and field-dirty root the weights in each plant are similar to the standard of the plantations, we do not have the data of the absolute control.
