Abstract
The nematicidal potential of soil amendments with pelleted alfalfa meal was investigated on the root-knot nematode Meloidogyne incognita on tomato and on the cyst nematode Heterodera carotae on carrot in two field experiments in Southern Italy.
Application of 20 and 40 t ha-1 alfalfa pellets was compared with 30 L ha-1 quillay formulation and 30 L ha-1 emulsifiable phenamiphos, whereas nontreated soil was used as a control.
Alfalfa pellets strongly suppressed soil population density of M. incognita and H. carotae compared to nontreated soil, with no significant difference from phenamiphos.
Nematode infestation was significantly lower at the highest pellet dosage in the trial M. incognita, whereas no difference between the suppressivity of the two amendment rates was found on H. carotae. Both dosages of alfalfa pellets remarkably increased tomato and carrot yield and improved carrot tap root quality compared to nontreated soil and quillay extract treatment, but significantly less than phenamiphos.
Based on the results from these experiments, soil amendments with pelleted alfalfa meal seems to represent a further valuable tool for a sustainable control of phytonematodes, also due to technical feasibility and positive effects on soil fertility.
