Q

Tobacco Control Program

A

Growers agreed to production quota for guaranteed prices. Graded by federal grader and sold at auction. Unsold tobacco purchased by co-op, sold later.

Brought stability, but improved management through advancements in agriculture lead to overproduction (1955-1970).

Major change in 1971: production limits based on acreage/poundage… 1975 only weight considered for burley.

Q

Factors leading to demise of tobacco program

A

Unpopular with public, even without tax payer support.

Price stability = quota instability. Artificially high leaf price compared to world market (well above production costs).

Cooperative surplus stocks… high stocks of poor quality, with government rescues (‘going to the well too often’).

High lease prices.

Contracting gained strength and market moved away from auctions.

Q

Factors driving shift from conventional plant beds to float bed production

A

Uniformity - plants have equal space and access to resources (water, soil, fertilizer, etc).

Less seed used - one seed per cell = less waste

Controlled environment - allows ideal conditions for development

Transplant shock - less trauma to roots when transplanted from float system instead of ripped from soil.

Q

How did the shift to float plants influence other areas of tobacco crop management?

A

Disease and pest management begin in a controlled environment which can lead to healthier transplants taken to the field, increasing yield potential.

Tiered production separated into components, with some producers only growing transplants for sale.

Labor, while still necessary, was needed for less time overall (conventional - weather dictates setting time, float systems - producers make call)

25
Best management practices for clipping?
Start early (1.5 - 2 inches in height) ... 4 weeks? Slow blade speed (decreases pulp residue) Catch clippings Wash and sanitize after use
26
Contributing factors for Spiral root
Negative geotropism... hard seed coat hot, sunny dry conditions poorly wicking, compacted media
27
Management / prevention of spiral root
Never produces usable plant... best to avoid. Do not overpack trays. Dibble 1/2 inch deep gently tamp trays after seeding to settle media cover lightly with media after seeding
28
Describe the breeding process involved in creating disease resistance.
ID traits of interest. Locate source of trait (variability within class, genus, or species). Transfer trait to cultivar with desirable characteristics. Check for presence in offspring... Pure Line Selection - pick optimal plant in population. Only propagate that plant's seed. Backcrossing - F1 hybrids backcrossed with parents. GE - genetic transfer of material ... not accepted by global tobacco industry Marker Assisted Breeding - ID genetic 'markers' to monitor success of conventional breeding. Accepted.
29
Desired N fertility in float systems?
100ppm
30
Characteristics of vented heating system
15-20% heat loss to outside Larger/heavier inputs per BTU
31
Characteristics of unvented heating system
Added moisture within greenhouse Increased risk of plant damage during extended run times.
32
Characteristics of radiant heating system
Heats surfaces, not air Increased risk of plant damage during extended run times.
33
Goals of greenhouse ventilation systems
Maintain control of environmental conditions, particularly temperature and humidity, as to prevent pest/disease issues and promote desirable plant growth.
34
Should a grower be more concerned about hot or cold temperatures during germination? Why?
Hot - can kill seedlings. | Cold - just delays germination.
35
Double layer vs single layer cover
Layer of air between provides cost-effective insulation to help maintain desired internal temperature. Helps reduce condensation and excess moisture inside greenhouse.
36
Describe White Burley characteristics
Pale green leaves with creamy white stalk/veins, open leaf structure. Easy to handle. Cures quickly, good quality, no priming necessary. Well-suited for flavoring additives (up to 25% of weight).
37
Compare/contrast N. tabacum and N. rustica
N. rustica = - smaller, darker leaves - harsh smoking - more nicotine - origins in Mexico -> Pacific -> US -> Europe - 12 pairs of chromosomes - found in the wild. N. tabacum = - larger leaves - mild, rich taste - less nicotine - origins traced to Ecuador/Peru -> Cuba, Venezuela, Panama - 24 pairs of chromosomes - not found growing wild (result of hybridization).
38
How did Spindletop get its name?
Original owners Miles and Patsy Yount made their fortune in Spindletop oil field in Beaumont, TX.

45
First evidence of cultivation in Kentucky?
Prior to European arrival, cave and cliff dwellers of central and eastern KY... 'Modern' production noted in 1752 with John Finley in Woodford County.
46
Intro to Europeans

Spanish intro in early 1500s. Jean Nicot intro to France in 1560... proclaimed health benefits pre-1600s... proliferation through 16th - 17th centuries
48
Name of tobacco in West Indies?
uppowoc
49
Cohiba
powdered tobacco snorted with tabago
50
How was tobacco taxed during the reign of King James I?
per hogshead ... which is a barrel. Weight wasn't factored in, skewed taxes paid on actual weight (600 lb at first - 1 - 1.3k lbs stuffed)
51
First colonial export of tobacco?
1610, from Jamestown to England.
52
Describe colonial tobacco production protocols.
Jan/Feb - clear, burn, prepare plant beds (sterilize) March - sow beds, cover with pine boughs, later thinned to 4inch spacing May - plant fields during rainy period... 'hills' every 3 - 4 feet Weekly cultivation and hand removal of pests, bottom leaves, and suckers... Cut, wilt, and cure similar to today.
53
Implications of tobacco production in colonial times
Production was land intensive... and crops rapidly depleted soil. New land was constantly cleared, leading to westward expansion.
54
John Finley
Earliest reported KY tobacco cultivator... 1752 in Woodford County.
55
Why were exports difficult in early production?
Isolated areas... River best route, but dangerous due to pirates and natives. Routes hard to follow with changing channels and water levels.
56
Discovery of flue-curing
~1840s Captain Slade's slave Stephen discovers dry heat turns tobacco bright yellow -> Bright Leaf Tobacco is born!
57
Bright Leaf
Flue-cured. Mild, aromatic. Process discovered in 1840s.
58
How/when did White Burley come into existence?
1864 - George Webb and Joseph Fore Mutant burley.
59
Black shank
Oomycete, soil-borne pathogen. Introduced through roots, systemic infection through vascular system. Wilt during day 1st symptom.
60
Three tiered approach to disease management?
Rotation, Resistance, Chemical treatments
61
Tobacco seed costs?
Roughly static... 10k pack of seed = 1 acre + Less than $30/pack.
62
Virginia Tobacco Inspection Act of 1730
Required inspection for all exports - inferior product was rejected. Raised Virginia's status ("the" standard).
63
Marketing conditions prior to Agricultural Adjustment Act of 1933
Volatile market plagued with repeated cycles of oversupply and uncertain prices. Shady business practices on both sides. Growers forced to sell at low cost determined by The Trust. When dissolved, Old Pool marketing practices proved successful until grower membership decreased below required thresholds... which returned volatility to market.
64
How did growers compensate for price decreases? Consequences?
Some introduce 'trash' weight: leaves, dirt, and floor sweepings. Also 'nesting': lesser quality tobacco in middle of bales. Quality/reputation takes huge hit - inspires VA Tobacco Inspection Act
65
Dominant hogshead market in KY?
1825, Louisville.
66
Introduction of pre-rolled cigarettes
~1870s. Luxury items. Hand-rolled: 4 cpm Bonsack, 1880. Machine: 200 cpm
67
John Bonsack
Inventor of the first cigarette-rolling machine, capable of producing 200 cigarettes per minute versus hand-rolling at 4 per minute.
68
The Association
Formed in 1904 to force better prices. Began in Black Patch areas of KY and TN. 70% growers joined. Targeted The Trust with increasingly violent means until 1908.
69
Black Patch War
Began Dec. 1, 1906 in Princeton, KY. Lasted through 1908. Between The Association and The Trust. Three major events: 1. Princeton, 1906. 200 riders, burned largest tobacco factory in the world. 2. Hopkinsville, 1907. Burned three warehouses, shot up police station, took over fire department and train depot. 1 rider killed, another wounded. 3. Russellville, 1908. 55 riders destroyed two factories.
70
"The Trust" holdings by 1910
Dominated ~80 - 95% for all categories of smoking products except cigars.
71
The "Big Four"
Liggett and Myers R.J. Reynolds American Tobacco Company* Lorillard* * absorbed by RJ
72
"American blend"

73
Philip Morris Company
1902, first British tobacco shop opens in US; markets Marlboros to ladies. 1929, purchased cigarette factory in Richmond, VA. Manufactures own smokes, #1 in US and #2 in world. Marlboro #1 brand worldwide.
74
Events impacting Tobacco Growers, 1964 - 1983
1964, Surgeon Generals Report - smoking harmful to health. Changes 1981, companies say farmers can't produce enough... 1982, farmers overproduce - much of which went to the pool; led to No-Net-Cost Tobacco Program Act. 1983, severe drought, record low yields, poor quality, much went to pool.
75
Tobacco Improvement Act
1985, reduced prices = $0.30 per pound. established new formulas to control production. No new quotas issued, pre-existing quotas recalculated based on historical share. Set prices increased. Established buy out of pool stocks, "erased" bad tobacco from books. Ultra poor quality dumped in landfills.
76
basic vs effective quota
basic: determined by formula effective: actual production effective has largely exceeded basic every year...
77
No-Net-Cost Tobacco Act
No cost to public. Grower paid 1 cent per pound to no net cost fund, matched by tobacco buyer.
78
US Attitudes on Tobacco use
1960/70/80's - Surgeon Generals report raises awareness of harm in smoking. Mounting medical evidence. Ad restrictions imposed. 1990/2000's - Anti-smoking activism, mounting legal action against tobacco companies, increased taxes, indoor smoking bans General decline in use after plateau in 70s/80s ... worldwide consumption still going up!
79
Master Settlement Agreement
1998... two phases. Phase 1 - companies reimburse states for medical expenses related to treating smoking related diseases. forced restrictions and anti-smoking program funding. funded by cig price increases. Phase 2 - companies agree to additional payments to tobacco growing states to be paid to growers to offset expected losses due to price increases. Payments ended with the Buyout in 2004.
80
which countries export the most tobacco to the US?
Argentina, Brazil (quality), Africa (filler)
81
The Family Smoking Prevention and Tobacco Control Act
2009 - FDA regulates tobacco (marketing, manufacture, distribution)... but no direct authority over tobacco production.
82
Characteristics of nicotine
in plants, anti-herbivore and natural insecticide in mammals... +: alertness, memory, calmness, appetite suppression -: increased blood pressure, heart rate, dependency
83
Lineage of Nicotiana tabacum
Natural interspecific hybrid: N. sylvestris + N. tomentosiformis = N. tabacum parents. Allotetraploid: four genomes, two sets coming from different species than others... full set of chromosomes from each parent species.
84
Floral characteristics
complete, perfect flowers. highly self-pollinated. natural outcrossing limited.
85
Alkaloid production in burley
two loci control... nornicotine most common alkaloid in N. species except N. tabacum... may have lost ability to convert?
86
Desirable characteristics in breeding objectives
Pest resistance - degrees... immunity, single gene traits are easy to overcome; tolerance, multiple genes, often additive. Increased yield (weight) improved quality (visual, future focus on leaf chem) ease of handling (upright leaves)
87
When did tobacco hybridization begin in the US?
1950s... allowed immediate incorporation of desirable traits in one generation.
88
heterosis
hybrid vigor
89
Regional Variety Test Program
New varieties must meet standards... - genetically stable - comparable to check varieties in terms of physical characteristics (% usable leaf, grade index) and chemical composition (nicotine, nitrogen levels) - smoke panel (phased out?)
90
Current/Future Breeding efforts
Leaf chemistry - harm reduction, flavor enhancement mechanical harvest characteristics - reduced sucker potential, upright leaves Pest resistance
91
Criteria for burley variety selection
variety resistance matched to disease potential high yields across range of environments consistent quality manageability
92
conventional ground beds and practices
used from colonial times to early 1900s... required burning, steaming, or fumigation in fall. seed bed prep in Feb/Mar ... sow in Mar/Apr ... transplant/thin in May
93
effects of conventional transplants on crop growth and management
management = limiting factor... amount transplanted - pull in am, delay until after hottest part of day, transplant late afternoon time of transplanting - growth controlled by weather, often delayed due to plant size (May/June), rainy weather causes unchecked growth in bed transplant shock - differences in sizes resulted in variable recovery and crop uniformity
94
benefits of float systems
producer has better control over growth (temps) timing - can set all day = more set/day = more time for other activities minimal transplant shock more uniformity
95
disadvantages of float systems
allows producers to set more than they can manage tends to set shallow (less of an issue nowdays) increased disease risk (high humidity) in greenhouse
96
When did float systems take over?
~1988 ... complete changeover in mid 90's.
97
stalk positions and associated leaf names
low - flyings med - lugs upper mid - leaf top - tips
98
effects of root growth before and after transplanting...
bottom line: water roots are not significantly impactful for accelerated growth after transplanting
99
dis/advantages of in/outdoor float systems
``` Greenhouse - higher investment + higher usability + less risk + greater uniformity + more control ``` ``` Outside bed + lower investment - lower usability - increased risk (weather loss) - labor (clipping, spraying) ```
100
impacts of water quality
issues with high alkalinity do not use untreated water (ponds, creeks, etc)
101
most common size tray?
242 and 288 compromise between maximizing plants per unit area and final transplant size
102
issues with polystyrene trays
roots can permeate pores and harbor disease limited life - weathering ... UV, wear and tear environmental footprint
103
media characteristics
solid particles... pore space: large - drainage, air occupies center pores small - capillaries (water wicking)
104
Why is proper tray filling critical?
becomes heavy and water-logged (>8lbs diagnostic)... can sink floats low in water with excessive algae growth Poor growth (yellowed) and increased presence of spiral root "light and loose is best - let gravity do the work!"
105
Calculating water volume
trays * depth of water * 1.64 ex. 759 * 4.5 * 1.64 = 5600 gal
106
Calculate N fertility
Want 100ppm, using 20-10-20. 520 trays, 4" deep. lbs of fertilizer? ------ 520 * 4 * 1.64 = 3411.2 gal 3411.2 gal * 8.34 lb/gal = 28449.408 lbs (1/10,000) ... 100ppm = 2.84 lbs / .20 N = 14.2 Need 14.2 lbs 20-10-20
107
sources of N
nitrate - best, readily available form ammonium - marginal urea - worst, can convert to ammonia or nitrite (toxic)
108
Conductivity measurements...
measures electrical flow in mS (milli-Siemens) Take reading of source, take reading of fert water, check conductivity chart ex. 1.4 (fert) - 0.4 (source) = 1.0 mS from chart, @ 1.0 mS = 150 ppm N
109
insect pests of float systems
variegated cut worms (sig damage in short time, only at night) shoreflies/fungus gnats (nuisance) aphids flea beetles blood worms (feed on algae, not tobacco) slugs mice sow bugs
110
control of insect pests in float systems
Monitor regularly baits and habitat destruction spray with acephate (Orthene)
