The second part of the pub number is just a sequential number.

Series: Tobacco Disease: Plant Pathology Factsheet

Fungicide Guide for Burley and Dark Tobacco, 2016
2/24/2016 (minor revision)

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-8

Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management
7/1/2015 (new)

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-5

Blackleg of Tobacco
6/1/2011 (new)

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-4

Collar Rot in the Tobacco Float System
5/1/2011 (new)

Collar rot can be found in tobacco float beds each year in Kentucky; it causes a great deal of concern when it makes its appearance. Severe losses to this disease are rare, but they can occur if care is not taken to minimize the risk of disease development and prevent further spread after it does appear. | PPFS-AG-T-3

Managing Target Spot and Rhizoctonia Damping-Off in the Float System
5/1/2011 (new)

Damping-off and target spot occur each year in Kentucky. They can cause significant levels of damage to tobacco seedlings if cloudy, rainy conditions prevail. Once considered minor problems in float beds, both diseases 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-2

Pythium Root Rot in Tobacco Float Systems
5/1/2011 (new)

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. | PPFS-AG-T-1
