Afrikaantje bestrijdt wortellesieaaltje best (2009)
Afrikaantjes bestrijden wortellesieaaltjes beter dan wilde haver, stelt PPO Lelystad. Maar afrikaantjes zijn slecht in de meeste bouwplannen in te passen
Alleen in een nat jaar is bestrijding zinvol (2009)
In een droog voorjaar ondervinden gewassen weinig schade van paratrichodorus pachydermus. Volgens PPO is bestrijding van dit aaltje dan ook niet rendabel, dat is het allen in een nat jaar
