Multifarious management of the reniform nematode, Rotylenchulus reniformisinfecting cowpea

Anti-nemic capability of nine agrochemicals that included fertilizers, commercial plant growth supplements and chemicides applied singly and combined as foliar spray (f) or soil drench (Sd) was investigated in pot experiments for the management of the reniform nematode, Rotylenchulus reniformison cowpea plants. The accomplished findings showed that the lab prepared formulation “Combo” twice applied mastered the rest of the treatments in reducing the nematode’s soil population/pot (80.47%) besides lessening counts of the developmental stages, mature females, egg masses and eggs/egg mass per root with percentages 79.30, 80.37, 92.66 and 63.08, respectively. Ranked next was the Acadian seaweed incorporated with Vydate half dose soil drench treatment but was only inefficacious against the eggs number/egg mass where it caused insignificant reduction (26.63%). The number of egg masses/root was the most significantly affected nematodes’ developmental parameter by all the applied treatments followed by the number of soil population/pot. On the other hand, the least respondent parameter to the treatments applied was the number developmental stages/root followed by the number of eggs/egg mass then the number of females/root. The measured vegetative growth indices verified the role of the treatments applied in the endurance of plant health to the infestation, with an exception to the impaired number and weight of pods. This experimental work aimed at paving the way for the gradual displacement of synthesized nematicides and the shift towards less hazardous nematodes combating strategies through the merge of nematode specific with non-nematode specific compounds.
