Mold On Cut Seed Potato?

It is not uncommon to see mold growing on cut seed potatoes. If you have seen it, then you are aware that there may be problems with your potato crop. You might even think that you need to buy new seeds or replant the cut plants. However, if you follow these simple steps, then your potato crop will grow normally again!

How To Avoid Mold Growth On Cut Seed Potatoes?

1) Do Not Wash Your Cut Plants With Soap: Wash your cut plants only once a week.

This way you do not wash them with soap which could cause mold growth. Wash them with water only. If you wash them with soapy water, then they are likely to get moldy. Also, if you use detergent, then the soil around the roots of the plant gets contaminated too and that is where the problem lies.

2) Do Not Use Bleach Or Any Other Chemical For Washing Cut Plant: Bleach or any other chemical for washing cut plants is not good idea.

They contain harmful chemicals such as chlorine and ammonia which can damage the roots of the plant. These chemicals are poisonous to plants and can kill them very quickly. Therefore, bleach should never be used for washing cut plants.

3) Cut The Plants At Right Time: Do not cut the plants when they are too young.

Wait for them to grow bigger. Also, do not cut them when they are fully grown. Cut them only when they have grown bigger than your finger but before they start showing signs of yellow coloration or bulging at the base. If you cut them when they are too young, then mold will grow on the cut plant. If you cut them when they are fully grown, then they will not sprout properly.

4) Clean And Sterilize The Scythe Before Cutting: Before you start cutting the plants, clean and sterilize the scythe.

This will prevent any mold from growing on the scythe. It is very important to keep the scythe clean at all times.

5) Do Not Store The Cut Plants Near The Floor: After you have cut your plants, do not store them near the floor of the shed or near the floor of the house.

Otherwise, they will be in contact with the soil and any mold spores that may be there hence increasing the chances of mold growth on your plants. Always store them away from the floor in a dry place.

6) Spray The Cut Plants With A Fungicide: After you have cut the plants, spray them with a fungicide.

This will prevent any mold from growing on them. You can either prepare your own home made fungicide or buy a commercial one from the market. Homemade fungicides are very effective as well and you can prepare one at home which is usually as effective as commercial ones.
