Other claims from this paper (12)

Intervention effect Cotton growth and yield were best with fumigants combined with organophosphate nematicides.
Intervention effect Cotton growth and yield were best with fumigants combined with carbamate nematicides.
Intervention effect Organophosphates alone failed to give season-long root-knot nematode control.
Intervention effect Carbamates alone failed to give season-long root-knot nematode control.
Mechanism Long-term control was poor because temporary sublethal effects diminished soon enough for nematodes to reproduce.
Observation Nematodes survived treatments and a year of nonhost culture and damaged a susceptible crop two years after treatment.
Intervention effect Fumigant-treated plots showed no such subsequent crop damage.
Intervention effect Fumigant plus organophosphate plots showed no such subsequent crop damage.
Intervention effect Fumigant plus carbamate plots showed no such subsequent crop damage.
