Glossary beginning with N




Nematodes are a diverse phylum, but in terms of coffee agriculture, there are both beneficial and negative-acting nematodes. Depending on the species, a nematode may be beneficial or detrimental to plant health.From an agricultural perspective, there are two categories of nematode: predatory ones, which will kill garden pests like cutworms, and pest nematodes, like the root-knot nematode, which attack plants.Predatory nematodes can be bred by soaking a specific recipe of leaves and other detritus in water, in a dark, cool place, and can even be purchased as an organic form of pest control. Rotations of plants with nematode resistant species or varieties is one means of managing parasitic nematode infestations. For example, marigolds, grown over one or more seasons (the effective is cumulative), can be used to control nematodes.[11] Another is treatment with natural antagonists such as the fungus gliocladium roseum.
