Common Disease Problems
Black Rot: This bacterial disease thrives in warm and humid conditions and attacks the leaves. Yellow-orange V shaped lesions occur on the edges of the leaves and eventually dry out and the leaves fall off. Burpee Recommends: Rotate crops with plants in a different family. Avoid overhead watering. Provide adequate air circulation, do not overcrowd plants. Do not work around plants when they are wet. Control weeds where the disease can overwinter.
Damping Off: This is one of the most common problems when starting plants from seed. The seedling emerges and appears healthy; then it suddenly wilts and dies for no obvious reason. Damping off is caused by a fungus that is active when there is abundant moisture and soils and air temperatures are above 68 degrees F. Typically, this indicates that the soil is too wet or contains high amounts of nitrogen fertilizer. Burpee Recommends: Keep seedlings moist but do not overwater; avoid over-fertilizing your seedlings; thin out seedlings to avoid overcrowding; make sure the plants are getting good air circulation.

Stem Canker: Part of the stem looks sunken and turns brown. The stem will wilt. This is caused by a fungus. The canker can open and ooze sap. This fungus can spread to all parts of the plant causing the plant to die. Burpee Recommends: Remove any infected stem as soon as you see symptoms. Rotate crops. Try not to get the stems and leaves wet when watering the plant.
Common Pest and Cultural Problems
Aphids: Greenish, red, black or peach colored sucking insects can spread disease as they feed on the undersides of leaves. They leave a sticky residue on foliage that attracts ants. Burpee Recommends: Introduce or attract natural predators into your garden such as lady beetles and wasps which feed on aphids. You can also wash them off with a strong spray, or use an insecticidal soap.

Leafminers: These insects bore just under the leaf surface causing irregular serpentine lines. The larvae are yellow cylindrical maggots and the adults are small black and yellow flies. They do not usually kill plants, but disfigure the foliage. Burpee Recommends: Remove affected foliage. Sanitation is important so be sure to remove all debris at the end of the season.
Spider Mites: These tiny spider-like pests are about the size of a grain of pepper. They may be red, black, brown or yellow. They suck on the plant juices removing chlorophyll and injecting toxins which cause white dots on the foliage. There is often webbing visible on the plant. They cause the foliage to turn yellow and become dry and stippled. They multiply quickly and thrive in dry conditions. Burpee Recommends: Spider mites may be controlled with a forceful spray every other day. Try hot pepper wax or insecticidal soap. Check with your Cooperative Extension Service for miticide recommendations.
Sunscald: Leaves are bleached in between veins and faded, often turn white with brown crispy edges. There are no signs of pests and diseases. Plants were usually recently moved. The bright light and heat from the sun break down the chlorophyll which leads to death of the leaf. Burpee Recommends: Some afternoon shade would be helpful, but keep the plants as healthy as possible.
