Title
NEMATICIDAL EFFECT OF TAGETES ERECTA STEM AND ITS EFFECT ON GROWTH OF CUCUMIS SATIVUS PLANT
Mengjiao Jiang Journal of Beijing Normal University 2012
Other claims from this paper (11)
- Intervention effect Longer incubation raised M.incognita mortality.
- Intervention effect Higher T.erecta extract concentration raised M.incognita mortality.
- Intervention effect At 12 hours, 1.5% extract yielded 89.4% nematode mortality.
- Intervention effect At 12 hours, 1.0% extract yielded 69.5% nematode mortality.
- Intervention effect At 12 hours, 0.5% extract yielded 44.2% nematode mortality.
- Intervention effect After 24 hours, every extract concentration gave 100% nematode mortality versus zero in controls.
- Intervention effect Stem additions reduced cucumber root knot counts, significantly at 0.5% and 2.0%.
- Intervention effect The 0.5% and 1.0% rates caused no negative change in height, shoot diameter or biomass.
- Intervention effect A 2.0% stem addition suppressed cucumber growth and decreased height, shoot diameter and biomass.
- Intervention effect Each stem addition rate decreased cucumber leaf chlorophyll content and net photosynthesis.
- Recommendation The authors advise suitable T.erecta stem rates for nematode control while accounting for photosynthetic harm.
