Tomato plants may develop yellow leaves as well as looking wilted. Solutions: Pay close attention to watering.
Why are my tomato plant leaves turning brown and dying?
Environmental issues, such as a lack of water, too much water, poor soil and too little light can also cause tomato plants to fail and die. Watering issues – When a tomato plant is under watered or over watered, it reacts the same way. It will develop yellow leaves and will look wilted.
What do Underwatered tomato plants look like?
Underwatering: Tomato plants that are temporarily water-stressed will have wilted leaves that are still green. Tomato plants that are regularly or chronically water-stressed conserve water in roots and stems while allowing leaves to yellow, usually starting with lower and older leaves.

Pick up and destroy fallen leaves. When pruning, cut out any stems with black spot on. In late-winter, spread a thick layer of mulch around the base of the affected plant to prevent rain splashing soil-borne spores on to new spring growth.
Can leaf spot be cured?
Remove infected leaves and dead twigs.
Raking up and disposing of infected leaves as they drop and pruning out dead twigs can help control the disease by removing spores that can reinfect the new leaves. This is not a cure but may help limit infection by reducing the total amount of inoculum.
Is black spot a fungus?
Black spot (blackspot) is the most important fungal disease of roses worldwide. The initial symptoms start as feathery-edged, black spots on lower leaves. As these spots enlarge, the leaves turn yellow and drop off. The disease continues up the stems until the entire plant becomes defoliated.

They migrate to the biting parts of the fly where they can be transmitted back to humans when it bites again. Humans become infected when blackflies deposit Onchocerca infective larvae into the skin when biting to extract blood. Once inside the human body, the larvae mature into adults in approximately 12–18 months.
