Ditylenchus destructor is a plant pathogenic nematode commonly known as the potato rot nematode. Other common names include the iris nematode, the potato tuber eelworm and the potato tuber nematode. It is an endoparasitic, migratory nematode commonly found in areas such as the United States, Europe, central Asia and Southern Africa.
Potato cyst nematodes are important economically due to the fact that they can substantially reduce crop yields. Globodera pallida are able to cause 80% yield loss in a potato field if left untreated. [8] On a more global scale, the Australian potato industry is worth about AUD$500 million yearly which equates to $340 million U.S. dollars. [7] [9]
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 ...
[5] [6] In a non-food crop such as cotton, reliance on natural frost may be too late to be effective in some regions. Thus leaves that remain on the cotton plant will interfere with mechanical harvesters and stain the white cotton resulting in a lower quality grade; herbicides which cause both defoliation and desiccation reduce these problems.

Fusarium dry rot of potato is a devastating post-harvest losses (vegetables) disease affecting both seed potatoes and potatoes for human consumption. [3] Dry rot causes the skin of the tuber to wrinkle. The rotted areas of the potato may be brown, grey, or black and the rot creates depressions in the surface of the tuber.
The study also showed that peeling removed 91–98% and washing 33–47%. Residues of chlorpropham were detected in the boiled potatoes, in the boiling water, in the French-fried potatoes and in the frying oil. According to this study, the theoretical dose for a 20 kg infant eating 100g of crude-peeled tuber would be 0.00018 to 0.00342 mg/kg.
