All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The interaction of herbicides and Northern root-knot nematodes (Meloidogyne hapla Chitwood) on onions and beans was studied in the greenhouse. Seeds of onions (Allium cepa L.) were planted in soil treated with different levels of dimethyl 2,3,5,6-tetrachloroterephthalate (DCPA). Seeds of beans (Phaseolus vulgaris L.) were planted in soil treated with different levels of DCPA or α, α, α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin). Seedlings were inoculated with root-knot nematode larvae after 2 week's growth.
DCPA reduced root and shoot growth on onions but did not significantly affect bean growth. Trifluralin significantly reduced root and shoot …
