College publications are given 2-part "pub numbers" that are used to identify them. The first part (the prefix) is a set of letters that indicates which series the document belongs to. A series is a grouping of documents that share similar content. The second part of the pub number is just a sequential number.
In descending order, by date published.

Bacterial spot can result in severe damage to tomato, sweet pepper, and pimento crops. The bacterium attacks leaves, fruits, and stems causing blemishes on these plant parts. Outbreaks of leaf spotting have resulted in leaf drop and poor fruit set in the field. Defoliation due to leaf spotting can increase the incidence of sun scald on fruit. Fruit infections result in badly spotted fruit, which are of little market value. In addition, fruit injury from this disease allows entry of secondary fruit rotting organisms, causing further damage.

Bacterial wilt is a common, often destructive, disease of cucurbits. This disease can cause nearly complete losses of a planting before the first harvest. Bacterial wilt primarily affects cucumber and muskmelon (cantaloupe). While squash and pumpkin are also susceptible, the damage to these hosts is usually less severe.

Bacterial canker is a potentially serious disease of tomato that can occur in commercial plantings and home gardens. This infectious disease is capable of spreading rapidly, resulting in devastating losses. It is a particularly difficult disease to manage because not only is there no cure, but the pathogen can be hard to eradicate once it has been introduced into a greenhouse, garden, or field.

Cabbage, broccoli, cauliflower, kohlrabi, and brussel sprouts, all cole crops, are excellent plants to integrate into gardens. During wet seasons, bacterial diseases, fungal leaf spots, and downy mildew are common problems, while powdery mildew is more common during dry seasons. Bacterial diseases are also benefited by hot weather with occasional strong storms, which injure plants and spread pathogens in the garden.

Beans and peas, both legume crops, are excellent plants to integrate into gardens for multiple reasons. These plants are affected by few of the diseases that affect other popular garden plants. Beans and peas increase nitrogen fertility where they are planted, enriching the soil for the plants that are to follow them in a rotation. These plants can be extremely productive, and are a great source of dietary fiber and, in some cases, vegetable protein.

Solanaceous crops, including tomatoes, peppers, eggplants, and potatoes, may be the most popular garden plants, but many diseases commonly affect them. Early blight and Septoria leaf spot occur each year under even the best disease management, and bacterial spot may be spread easily under rainy conditions. A combination of approaches, such as using resistant varieties, record-keeping, cultural, and chemical management, is the best practice for minimizing vegetable garden diseases.

Leafy greens are great garden plants as a result of their short seasons, ease of growing, and ability to be succession planted. In wet summers, bacterial diseases, fungal leaf spots, and downy mildew are common problems, while powdery mildew is more common during dry summers. Bacterial diseases are also benefited by hot weather with occasional strong storms, which injure plants and spread pathogens in the garden. Lettuce drop, caused by the Sclerotinia fungus, can become a multi-year problem and may spread to different families of plants.

Cucurbit vining crops include cucumbers, watermelons, cantaloupe, pumpkins, zucchini, and summer and winter squashes, and can be highly productive plants in small gardens. During wet summers, downy mildew and fungal leaf spot diseases tend to occur, while in drier summers, powdery mildew is the most common disease. Gardens with cucumber beetle pressure are much more likely to have plants affected by bacterial wilt, since striped and spotted cucumber beetles can carry the bacterial wilt pathogen.

Blackleg and soft rot are bacterial diseases that cause heavy losses in Kentucky potato patches in some years. These diseases may result in missing hills when seed pieces are destroyed or the sprouts decay before they emerge from the ground. Serious rotting of tubers in potato hills and in storage can also occur.

Fusarium and Verticillium wilts are two fungal diseases that cause similar wilts in tomato. Fusarium wilt tends to be more common during warm weather, while Verticillium wilt is found more often when temperatures are cool. Both diseases share similar symptoms and can be hard to tell apart visually; laboratory tests are often needed for an accurate diagnosis.

Symptoms of yellow vine decline begin to appear approximately 2 weeks before fruit maturity. The disease may appear initially as stunting of plants and/or intense yellowing of foliage, followed by a slow decline in plant health. In some cases, a sudden collapse of vines may occur with no other symptoms. Vascular tissue (phloem) from crowns of affected plants is often discolored, appearing light brown rather than a healthy translucent green.

Gummy stem blight is an important disease of cucurbits in many parts of Kentucky. Under conditions favorable to disease development, commercial growers and home gardeners may experience heavy losses. This disease can occur at any point in plant growth, from seedling stage to fruit in storage. Gummy stem blight is the name given to the disease when leaves and stems are infected. Muskmelon (cantaloupe), cucumber, and watermelon are most commonly affected by this phase of the disease. Black rot refers to the same disease on fruit; it is seen less often than the foliar phase.

Under ideal conditions, Phytophthora blight is an aggressive, fast moving disease that can cause extensive losses. This disease has become increasingly problematic on cucurbits and solanaceous crops in the United States. During the past decade, Phytophthora blight has been causing significant losses in several major vegetable production areas of the U.S. In Kentucky, serious outbreaks have been reported on summer squash, winter squash, cucumbers, watermelons, and peppers.
