Latest Summary of Common Diseases and Pests of Eggplant and Their Control Methods

Eggplant is a vegetable we often eat. It is rich in nutrients and widely loved by people, but it is also very susceptible to diseases and pests. So what are the main diseases and pests of eggplant? And how should they be controlled? Below, Qinnong Net brings you the common diseases and pests of eggplant and their control methods.

1. Damping-off

Eggplant damping-off mostly occurs during the seedling stage of eggplant. When the disease occurs, the stem discolors and necroses, gradually shrivels, and the seedling lies close to the ground until the plant rots and dies.

Control methods: Choose varieties with good disease resistance for planting, disinfect the seeds and soil before planting, select a sunny plot with good drainage, and when the disease occurs, choose chemicals for spraying and sterilization.

2. Phytophthora fruit rot

Phytophthora fruit rot, also called rotten eggplant, is the most common disease of eggplant, with a relatively high incidence rate, especially severe in the plum rain season. When the disease is severe, a large number of fruits rot, seriously affecting eggplant yield.

Control methods: Likewise choose varieties with relatively strong disease resistance, disinfect the seeds and soil before sowing, prune frequently during the growth stage to ensure ventilation and light transmission, apply fertilizer reasonably to promote strong plant growth, and combine with chemical treatment when the disease occurs.

3. Sclerotinia rot

Sclerotinia rot is one of the common diseases of vegetables. It harms not only eggplant but also many common household vegetables. At the beginning of the disease, white cotton-like mycelium grows from the base of the stem as publication time goes on. In severe cases, the stems and leaves wither and die, and finally the entire plant dies, affecting yield.

Control methods: The pathogen of Sclerotinia rot mainly comes from the soil, so sterilization treatment of the soil is extremely strict. Carbendazim wettable powder can be mixed with soil and evenly spread on the planting site. When planting, pay attention to keeping warm and strengthening ventilation. If diseased plants are found, pull them out and burn them in time, and disinfect the soil where the diseased plants were planted to avoid infecting other plants.

4. Aphids

Aphids mainly feed on stems and leaves. At first the damage is relatively small, but when their numbers are too large, the harm to plants is also very great. They will directly eat the stems and leaves clean, causing the plant to die.

Control methods: When aphids are found, directly spray with specialized chemicals for treatment.

5. Red spider mites

Red spider mites are extremely small and often gather together to suck leaf sap. At first, small white spots appear on the leaves, then they slowly turn yellowish white. In severe cases, the leaves of the entire plant dry out and turn red, and the leaves fall off.

Control methods: Deal with them from the source, clean up fallen leaves and residual branches near the plants to reduce insect sources, and when pests are found, promptly spray with insecticides to kill them.

The above are the common diseases and pests of eggplant and their control methods brought to you by Qinnong Net. Doing a good job in eggplant disease and pest protection is the key point for eggplant planting yield, and it must be taken absolutely seriously.
