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.

Series: Tobacco Disease: Plant Pathology Factsheet



PPFS-AG-T-8
Fungicide Guide for Burley and Dark Tobacco, 2018

 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

The number of fungicides that are registered for use on tobacco in Kentucky is relatively small in comparison to the large array of products available to producers of other crops. Although growers have a limited number of fungicides from which to choose, those that are available are effective against most of the major diseases of roots, stems, and foliage.

PPFS-AG-T-3
Collar Rot in the Tobacco Float System
3/1/2018 (major revision)

 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

Collar rot can be found in tobacco float beds each year in Kentucky, causing a great deal of concern when it makes its appearance. Severe losses to this disease tend to be rare but can occur if care is not taken to minimize risk of disease development and reduce spread after it appears.

PPFS-AG-T-2
Managing Rhizoctonia Damping-off and Target Spot in the Float System
3/1/2018 (major revision)

 UK Authors: Emily Pfeufer

 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

Damping-off and target spot occur each year in tobacco transplant crops in Kentucky. These diseases can cause significant levels of damage to tobacco seedlings. Once considered minor problems in float beds, both have increased steadily in importance in recent years. Sound management practices and early recognition of these diseases are keys to preventing serious losses during the transplant production cycle.

PPFS-AG-T-5
Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management
7/1/2015 (new)

 UK Authors: Bob Pearce, Emily Pfeufer

 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

Management of resistance to fungicides is based on alternating the use of particular modes of action, or FRAC groups, which essentially presents multiple different challenges to the fungal population. Overall, fungi that are naturally resistant to a mode of action are very rare in the environment. Challenging a population with multiple different modes of action will reduce the chance of developing widespread resistance, which will prolong the efficacy of these chemicals.

PPFS-AG-T-4
Blackleg of Tobacco
6/1/2011 (new)

 UK Authors: Kenny Seebold

 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

Blackleg becomes a concern whenever Kentucky experiences extended periods of warm, wet, overcast weather in the spring. This disease, also referred to as bacterial soft rot, is one of the most serious problems likely to be encountered on tobacco seedlings. Blackleg has the potential for destroying large numbers of plants in a relatively short period of time. As with other diseases in the float system, proper management goes a long way in preventing problems with blackleg.

PPFS-AG-T-1
Pythium Root Rot in Tobacco Float Systems
5/1/2011 (new)

 UK Authors: Kenny Seebold
 Departments: Plant Pathology
 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

Pythium root rot is the most common disease found in tobacco float beds in Kentucky; it can cause severe losses or delays in transplanting. Damage caused by this disease can be minimized through a combination of sound management practices and timely application of fungicide.
