Granular Nematicides as Adjuncts to Fumigants for Control of Cotton Root-knot Nematodes.

E C Jorgenson PubMed 1979

Other claims from this paper (12)

Intervention effect Cotton growth and yield were best with fumigants combined with organophosphate 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.

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.
Intervention effect Organophosphate treatment of seed or cotton gave little or no yield increase because control was minimal and temporary.
