PESTS AND DISEASES AFFECTING AFRICAN NIGHTSHADE

APHIDS

Aphids are a major pest, causing leaves to curl and become unattractive to customers. Aphids feed by sucking plant sap. Small aphid populations may be relatively harmless, but heavily infested plants usually have wrinkled leaves, stunted growth and deformed pods. Plants, in particular young plants, may dry out and die under heavy aphid attack. Heavy attack on older plants may cause crop loss by decreasing flower and seed production. Damage may also reduce seed viability.

SPIDER MITES

The plant’s leaves and growth tips are susceptible to mites (very small, sucking arthropods) that result in twisted growth and low productivity. Generally, spider mites feeding may cause reduction in plant growth, flowering, number and length of berries, and number of seeds per berry. Damage is most severe when mites attack young plants. Mite damage may be particularly severe during the dry season.

EARLY BLIGHT

Leaf spots of early blight are circular, up to 1 cm in brown, and often show a circular pattern which distinguishes this disease from other leaf spots. Early blight thrives best under warm wet conditions. Leaf spots first appear on the oldest leaves and progress upward on the plant. Entire plant could be defoliated and killed. Controlling early blight once it has established is very difficult. The most important way of controlling early blight is attempting to prevent its establishment and further spread.

The flowers should be removed before the crop is taken to market. Water these bundles sparingly to retain freshness of the crop. This method of harvesting is the most preferred as it gives the farmer continual produce for 3 to 4 months. Remove the flowers regularly to ensure the managu plant continues to produce more leaves, instead of focusing its resources on developing the fruits.
