Terbufos is used on various crops including bananas, beans, citrus, coffee, groundnuts, sorghum, potatoes, sunflowers and maize as soil cover to combat wireworms, mossy beetles, beet flies and the black bean louse. [6] [7] It is not approved for use in the European Union. [8]
They are killed by dry conditions or temperatures below about −6 °C (21 °F) but compensate by moving down through the soil to a meter (yard) or so beneath the surface. They can survive for a long time without feeding. When fully-grown, the larvae pupate in late summer in the soil. The adults emerge two to three weeks later.
Potatoes are root vegetables that grow in soil underground. Even after picking, potatoes almost always carry around some dirt and debris that may have some pesticides or bacteria in the mix.
The use of certified disease free seed will also assure that potato cyst nematodes are not present due to planting infected tubers. Soil testing for potato cyst nematodes is also crucial in keeping track of the prevalence of the nematodes. Controlling the quantity of the nematodes allows the prevention of an epidemic.
Desiccated potato plants prior to harvest. Pre-harvest crop desiccation is the application of an agent to a crop just before harvest to kill the leaves and/or plants so that the crop dries out from environmental conditions, or "dry-down", more quickly and evenly.

Sweet potatoes show clear lesions that grow rapidly leaving a recognizable watery and soft, oozy tissue where only the peel remains intact.
