For humans, this substance is toxic. If it is inhaled, even in a smaller amount can cause serious health problems and even death.

It is also around the place of damage as well as on green areas.

Why Do Potatoes Rot?

Potatoes rot is caused by different types of infection.

Rotting Of Potatoes By Bacterial Infections

The disease affects tubers, stems, leaves, and stolons.

When the tuber is cut, rot is visible, which is located around the circumference.

The disease is widespread and destroys up to half the crop.

Affected tubers can transmit the disease for several generations without symptoms.

The disease spreads when harvesting through damage to the skin of the tubers.

Rotting Of Potatoes By Brown Bacterial (Quarantine Disease)

Since 2011, the causative agent of the disease has been found on food potatoes from warm countries.

Infection occurs through the root system.

The first sign is the sudden withering of leaves, branches, and the whole plant.

The tuber turns brown and softens the vascular ring. During storage, the pulp is converted to dark mucus.

Potato Wet Rottin

Potato wet rot spreads quickly when stored in a warm and humid room with insufficient ventilation.

Damp rot – penetrates tubers through cuts, scratches, or cracks in the peel that occur when potatoes are affected by various types of scab.

Dry Rotting Of Potatoes

Fusarium (dry rot) is a disease that develops during storage of tubers.

Dry rot of potatoes affects tubers in the field, but the disease appears only during storage.

First, greyish-brown folds appear on them, then the flesh of the potato becomes loose.

And finally, the tissue dries, cavities with fluffy mycelium appear inside.

Fusarium potatoes in storage are transmitted only to tubers with damaged peels.

Ring Rotten Potatoes 

A tuber girdles a wide yellow ring of infected tissue.

The disease is dangerous because a diseased tuber is almost impossible to distinguish from a healthy one.

Rotten patches of pulp are visible only on the cut of potatoes.

Do not put potatoes near the battery – as soon as the heating is turned on, they will become soft and germinate.

The best option for storing potatoes is a wooden box with double walls and a lid, lined with sawdust, shavings, or polystyrene foam from the inside.

At the bottom, it can be laid straw – it absorbs moisture perfectly.

The box can be placed near the balcony or under the window.

In the latter case, it is necessary to keep the window open.

The optimum temperature for storing potatoes is (6–10°C) degrees Celsius.

If you are holding potatoes in a bag, it is better to choose not a plastic bag, but a bag of fabric, so that light does not penetrate there.

Otherwise, the tubers will sprout.

Do not store potatoes in the refrigerator, as potato starch can turn into sugar, and root crops will acquire an unnaturally sweet aftertaste.

Such potatoes have a greenish tint.

Root crops should be periodically sorted.
