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 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.
Intervention effect Organophosphate treatment of seed or cotton gave little or no yield increase because control was minimal and temporary.
Intervention effect Carbamate treatment of seed or cotton gave little or no yield increase because control was minimal and temporary.
Intervention effect Organophosphate treatments could decrease yield through toxicity when nematode populations were low.

Intervention effect The split-root high EC treatment reduced tomato leaf area.
Association Reduced tomato leaf area under split-root high EC corresponded with low leaf K concentration.
Intervention effect Doubling the rooting volume with the split-root method had no detectable effect on tomato leaf expansion, yield or fruit quality.
Intervention effect The high EC split-root treatment had little impact on tomato yield for the first ten weeks.
Intervention effect The high EC split-root treatment reduced weekly tomato yield thereafter, by about 9 and 13% in Solairo and Espero.
