Cutworms (Agrotis spp.) are major nocturnal pests of potatoes, cutting stems and damaging tubers causing 20–80% yield loss. Found globally, they thrive in weedy, moist soils. IPM with cultural, biological and chemical control is key to sustainable management.

Potato flea beetles (Epitrix spp.) are global pests causing foliar shotholes and tuber damage, spreading rapidly via adults and trade. Climate change, resistance and cryptic larvae exacerbate yield losses, demanding integrated management combining cultural, biological and chemical strategies.

Ladybird beetles are vital biological control agents in potato ecosystems, suppressing aphids that damage plants and spread viruses like PVY and PLRV. By reducing pest populations, they improve crop health, yield, tuber quality and support sustainable, low pesticide potato production.

Leaf beetles (Chrysomelidae) are highly diverse herbivorous insects with global distribution many acting as major crop pests causing major agricultural losses. They require integrated pest management due to resistance, climate and spread.

Spider mites (Tetranychus urticae) threaten global potato yields by thriving in hot, dry climates, causing severe defoliation and losses. Integrated pest management combining monitoring, cultural, biological and chemical controls is vital for sustainable suppression.

Pea leafminer fly (Liriomyza huidobrensis) in potato causes severe yield losses through serpentine leaf mining, reduced photosynthesis and poor tuber growth. Learn symptoms, lifecycle, crop damage, identification and effective IPM strategies for sustainable control.

Potato leafhopper (Empoasca fabae) is a major sap feeding pest that causes hopperburn, stunted growth and significant yield losses in potatoes and other crops. Early identification, regular scouting and integrated pest management are essential for effective control.

Potato Ring Rot is a serious bacterial disease caused by Clavibacter sepedonicus that threatens seed potato production worldwide. Explore symptoms, disease cycle, transmission, diagnosis, quarantine regulations and management strategies.

Powdery scab is a major potato disease caused by Spongospora subterranea, reducing tuber quality and marketability. Learn about symptoms, disease cycle, PMTV transmission, diagnosis and integrated management strategies for effective control.

Potato thrips are major potato pests that cause feeding damage and transmit plant viruses. Discover identification, life cycle, symptoms, crop damage, monitoring and integrated pest management (IPM) strategies for effective thrips control.

Phthorimaea operculella, known as the tomato or potato tuber moth is a major global pest of potatoes and other solanaceous crops. Its larvae damage leaves, stems and tubers, causing severe yield and storage losses making IPM essential for control.

White grubs are destructive soil-dwelling potato pests that damage roots, stolons and tubers, reducing yield, quality and storage life. Integrated pest management using cultural, biological and chemical controls is essential for sustainable control.

Whiteflies are an emerging threat to global potato production, causing feeding damage, virus transmission and major yield losses. Learn about whitefly species, symptoms, climate risks, economic impact and IPM strategies for potato crops.

Potato aphids are major potato pests that damage crops through sap feeding and virus transmission, including PVY and PLRV. Effective integrated pest management (IPM), monitoring, resistant varieties and sustainable control reduce yield losses worldwide.

Potato bud midge (Prodiplosis longifila) is a serious potato pest that damages buds and growing points causing stunting, distorted growth and significant yield loss. Early detection, regular scouting and integrated pest management (IPM) ensure effective control.

Colorado potato beetle (Leptinotarsa decemlineata) is a major potato pest causing severe defoliation, yield losses and rising insecticide resistance. Learn its identification, life cycle, damage, global spread and IPM strategies to protect crop

Early blight is a major fungal disease of potato caused mainly by Alternaria solani, leading to leaf spots, premature defoliation, reduced tuber yield and poor quality. Warm, humid conditions favor disease spread making integrated management essential for control.

Ostrinia nubilalis is native to Europe and was introduced into North America near Boston (Massachusetts) in 1917. It gradually spread from there to other parts of the United States and Canada. It has also been reported in Asia (China, India, Georgia and Indonesia, middle East (Syria, Israel, Lebanon, Iran, Turkey) and North Africa (Algeria, Egypt, Libya, Morocco and Tunisia). Two races, E and Z that are morphologically indistinguishable exist in both USA and Europe.

Potato tuber moth (Phthorimaea operculella) is a major global potato pest causing severe field and storage losses by larval tunneling in tubers. It spreads rapidly, reduces yield and quality and requires integrated pest management for control.

Potato wart disease (Synchytrium endobioticum) is a destructive quarantine pathogen causing severe potato yield and quality losses It persists in soil for decades, spreads via infected tubers and requires strict management, resistant varieties

Verschillende Dickeya bacteriesoorten veroorzaken ziektes in de aardappel, maar deze verschillen wat betreft symptomen en ernst.
Blackleg symptomen (zwarte stengels) worden hier ook besproken, ongeacht de ziekteverwekker die het veroorzaakt

Phytophthora infestans, ook vaak simpelweg aardappelziekte genoemd, is een aandoening die een aardappelveld kan verwoesten. Deze ziekteverwekker, een zogenaamde oömyceet veroorzaakte de Ierse Aardappel hongersnood (1845 - 1851) en is de reden van dat aardappeltelers aanzienlijke hoeveelheden gewasbeschermingsmiddelen gebruiken.

Aardappelmoeheid is een ziekte veroorzaakt door in de grond levende aaltjes (nematoden) die niet veel groter zijn dan 1 mm maar aanzienlijke schade kunnne veroorzaken aan de wortels van hun waardplanten, zoals de aardappel. Voorbeelden zijn de aardappelcystenaaltjes Globodera rostochiensis en Globodera Pallida. Beide nematoden hebben wereldwijd een quarantaine-status

The potato psyllid Bactericera cockerelli is native to North America and occurs mainly in the Great Plains region of the United States, from Colorado, New Mexico, Arizona, and Nevada, north to Utah.

Zebra chip-ziekte is genoemd naar de donkere strepen die zich vormen in aaangetaste aardappelknollen wanneer ze doorgesneden worden of worden gefrituurd om chips te maken.
