Potato Pests, Diseases and Physiological disorders
Potato production faces major challenges from pests, diseases, and physiological disorders that reduce yield and quality. Effective management through resistant varieties, clean seed, balanced nutrition, and integrated control ensures healthy, high-quality tubers.

Andean Potato Weevil 

Andean Potato Weevil
The Andean potato weevil severely threatens highland potato farming, causing up to 100% yield loss. Climate change, poor detection, limited IPM adoption and pesticide resistance worsen its impact, demanding sustainable, community-based management solutions.

Detecting Defects and Diseases 

Detecting Defects and Diseases
Any and all disorders and diseases of potato plants and tubers, whether caused by a biological agent (fungus, bacteria, virus, nemetode, insect, etc) or environmental (temperature, mechanical, oxygen availability, herbicide, etc)

Armyworms 

Armyworms
The armyworm is a rapidly spreading, highly adaptive pest damaging potato foliage and tubers worldwide. Its resistance, migration and climate resilience cause severe yield losses, economic strain and management challenges for farmers.

Bacterial Blackleg and Tuber Soft Rot / Pectobacterium 

Bacterial Blackleg and Tuber Soft Rot / Pectobacterium
Pectobacterium induced blackleg and soft rot severely impact global potato production, causing up to 50% yield loss. Latent infections, resistance, co-infections, climate change and poor seed certification complicate control, especially in smallholder systems.

Brown Rot and Bacterial Wilt / Ralstonia 

Brown Rot and Bacterial Wilt / Ralstonia
Potato brown rot, caused by Ralstonia solanacearum is a devastating, soil-borne bacterial disease affecting potatoes and solanaceous crops worldwide. It spreads via soil, water and contaminated tubers, causing wilting, tuber decay, yield loss and major economic impact.

Cutworms 

Cutworms
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.

Flea Beetles 

Flea Beetles
Flea beetles are small beetles and jump easily in the foliage of plants. Their feeding results in characteristic circular holes less than 3 mm in diameter. Larvae that feed on roots, stolons, and tubers also cause damage. They bore the tubers superficially or scratch the skin, thus facilitating penetration of pathogenic fungi.

Ladybird Beetles 

Ladybird Beetles
Potato ladybirds are polyphagous species feeding on a variety of plant species. However, most severe damage is usually reported for Solanaceae’s crops, including potato.

Mites 

Mites
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.
