Abstract

Ilocos region is the main producer of garlic in the Philippines. Bulbs from farmers’ previous harvest constitute the primary source of planting materials. While fungi, viruses, and bacteria are monitored, the equally damaging nematodes are not being reported. Hence, this study was conducted to determine the occurrence of plant-parasitic nematodes (PPNs) in major garlic growing areas in Ilocos Norte, Philippines. A total of 198 planting materials were randomly collected from these municipalities: Pasuquin, Vintar, San Nicolas, Batac City, and Pinili. Two PPNs were isolated from plant parts such as roots, basal plates, and cloves. Ditylenchus dipsaci is abundant in the clove and basal plate, while Aphelenchoides besseyi is abundant in the clove only. The abundance index of PPN (1.56-2.07) is above the threshold level in all municipalities surveyed. Abundance indices of D. dipsaci, A. besseyi, and their combined population are recorded at 1.76, 2.05, and 2.23, respectively. The nematodes at these levels have the potential to become economically important parasites in the locality where they were found.
