Prepare Soil and PLANT: Potato plants prefer cool moist weather. As long as the soil isn’t too wet, get them into the ground before March 1 for a June harvest.

Why are the leaves on my potatoes turning yellow?

Yellowing of Leaves – Disease prevention is the most important step for potato gardeners. Yellowing of the leaves is one of the setbacks in potatoes. Potatoes leaves are green in color. However, the leaves may yellow before the tubers are ready for harvest.

Wilt Two types of wilt potatoes cause yellowing in potato leaves: verticillium and fusarium wilt. The two diseases have slight differences, and thus they are not easily distinguished. Yellowing of the lower side of the leaves and drooping are the early symptoms of both types of infections. Later, the entire leaves develop bronzed appearance or black spots.

Verticillium Wilt Verticillium wilt causes the lower part of potato leaves to turn yellow. The yellow color spread to the upper side of the leave and eventually to the entire plant. The fungal infection also discolors some tubers and vascular tissue of the stem. Low temperature accelerates the infection, but symptoms are most evident during hot weather when the plant is loaded with tubers. Verticillium fungus prevents or limits water uptake; thus, infection is more severe when the temperatures are high, or the plant is water-stressed. Fusarium Wilt Fusarium wilt is a fungal infection favored by hot weather. A yellow color appears from the bottom and spreads upwards. The yellow color spread to the stem and plant tissues between the leaf veins. The symptoms may also spread to some tubers. Fusarium fungi survive in the soil for a long period, even without a host.

Preventing yellowing associated with wilt is challenging due to a lack of chemical controls. Growing potatoes in different parts of the land and rotating them with other crops such as legumes, grasses, and cereals can minimize verticillium and Fusarium species.

  1. Crop rotation reduces the levels of fungus in the soil that causes wilt.
  2. Planting a variety of potatoes resistant to soil diseases can prevent the yellowing of leaves.
  3. Besides, planting certified potato seeds is an effective strategy for preventing fungal infection.
  4. Certified seeds are thoroughly inspected and thus free from viral diseases.

Another remedy for wilt is planting resistant potato varieties such as Kennebec and Irish Cobbler to prevent infection. Psyllid Yellows Psyllid yellow is a common potato bacterial infection caused by Bactericerca cockerelli. The infection is characterized by an upright appearance of leaves and yellow foliage.

  1. Potato psyllids emit a toxin after feeding, causing a characteristic yellow color in the potato leaves.
  2. Initially, the yellow color appears at the edges of the leaves or between veins but eventually spreads to the entire plant.
  3. Apart from turning yellow, infested potato leaves curl upward to the stem, a symptom that becomes more evident over time.
