The pronotum and wing covers are covered in dense, short greyish hairs. The larva is known as a wireworm and lives in the soil. It is yellow, slender, stiff and leathery, and grows to a length of about 20 mm (0.8 in). The centre of the mandible has a small tooth for gnawing. [3]

Potato root nematodes or potato cyst nematodes (PCN) are 1-mm long roundworms belonging to the genus Globodera, which comprises around 12 species. They live on the roots of plants of the family Solanaceae, such as potatoes and tomatoes. PCN cause growth retardation and, at very high population densities, damage to the roots and early senescence ...

Depending on its species, a nematode may be beneficial or detrimental to plant health. From agricultural and horticulture perspectives, the two categories of nematodes are the predatory ones, which kill garden pests; and the pest nematodes, which attack plants, or act as vectors spreading plant viruses between crop plants.

Carbofuran is a carbamate pesticide, widely used around the world to control insects on a wide variety of field crops, including potatoes, corn and soybeans.It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained.
Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
Nematode assays need to be done before stepping on any managements later. Threshold for plant and first ratoons (per gram of roots) is 300 while threshold for old ratoons (per gram of roots) is over 900. [3] Crop rotation with legume plants on sugarcane fields can reduce the number of plant parasitic nematodes. However, this management has a ...
