Investigation and control of root knot nematodes on tea seedlings in South Yunnan


, : Investigation and control of root knot nematodes on tea seedlings in South Yunnan. Journal of Tea 19(4): 20-22

Root knot nematode disease is very serious for tea seedlings in south Yunnan. In seriously infected fields the percentage of diseased seedlings was 100% and mortality of seedling was 90%. Upto 3000 2nd stage juveniles can be found in 100 g soil and 80%, 15% and 5% juveniles in 0-20 cm, 20-30 cm and 30-50 cm deep soil resp. There are 7 growth peaks per year for 2nd stage juveniles inside roots.

All six strains suppressed J2 motility in a similar manner in vitro. In pot experiments, there was...
