Tomatoes
Cornear worm (aka: Tomato Fruitworm)
#1 INSECT PEST OF TOMATOES -Feed directly on Tomato -Control: -->Bt: affects stomach, worms have low pH so toxins will kill it.
Fresh Market
-determinate (get to a certain point, then stop growing) -interdeterminate (keep growing)
Cutworms
-Active only at night -lodging (cause) -Control: -->Remove grass and weeds -->Tin can method
Cornear Worm
-Aka: Tomato Fruitworm #1 insect pest of tomatoes -Feeds directly on tomato Control: -BT (Bacillus Thurengensis) -->Soil bacteria becaue worms have HIGH pH level and hamans don't so that's what wears away their layers (inner and outer)
Planting (transplant) dates
-Central Alabama: April 15 --> 60-90 days from transplant to mature fruit
Aphids
-Control: -->Wait for "crash," spray off with WATER, use insecticidal oil (sunspray) or insecticides -->Insecticidal soap
Late Blight
-Cool Nights: (50-60F) -Fall tomatoes -Control: --> Coversprays
Catfacing
-Cool weather at blossom time and causes the fruit to pucker and have deep crevices
Beet Armyworm
-Killing Cotesia wasp: induces them -Foilage feeders, mainly
Storage
-Mature Green: --> 55-70F; 1-3 weeks (Ethylene) -Pink: -->50-60F, 5-10 days -Ripe: -->50F; 4-7 days *Never put tomatoes in refrigerator= too cold!
Stinkbugs
-Mid-summer/fall pest; only when hot -Damage: -->Sunken areas on shoulders -Control: -->Sprays -->Natural Pyrethrums
Basics for Tomatoes (History)
-Native of tropical region of SOUTH AMERICA -first domesticated in MEXICO -Cortez took seed to EUROPE in 1915 -->Grown for Beauty of fruit except in Spain and Italy -Thought it was a poison -Introduced back to U.S. from Europe in 18th century after it gained popularity in cooking came to US. -George Washington Carver : recommended it for poor in Ala. because diets were low in vitamins
Control of Stinkbugs: Chrysanthemum flowers
-Natural pyrethrums -->grow flowrs in Sout Africa -->Separate oil out of flowers and mix with... -->Organic -->Works with green stinkbugs NOT brown ones -->Nerve poison -->Don't last long in the insect; sting them most of the time
Spider Mites
-Not an insect -Like dirty plants -Look for bronzing of leaves (they cause this) -->On the underside of leaves -love hot, dry weather -Avoid Sevin Dust --> can FLARE them!! -->Flare= kills the benneficial mites (preditorial mites) Control: -->Miticides (make suse you put on bottom sides of leaves. If not, you won't kill them.
Tomato Hornworm
-Only feed on plant, not fruit Control: -->pick off -->Bt (dust or spray) -Can be used as good fish bait.
Thrips
-Small, Stunted, purple plant Control: -->Resistance varieties -->Mulch -->Heavy sprays early
Grape
-Sweet -Smaller than cherry and oblonged
Early Blight
-The MOST common disease of tomatoes! -Favorable Conditions: -->rainy, humid weather above 75F -Infects: --> expand beyond 1/4" in sectioning; rotate with yellow halo. -Spray with Rain Splashea -Control Cover Sprays: protect fungicide
Basics for Tomatoes (Today)
-US #1 in fresh market tomatoes -Tomato Fruit is a "fleshy berry" (lawsuit) -->made it to supreme court to decide if it's a vegetable or a fruit. They ruled: it is both *(Botanically, it's a fleshy berry)*
Grow your own
-Use transplants -Depth 1/4 inch -Optimum Germination Temperature= 85F
Growing Tomato: Warm-Season
-Very sensitive to cold 1. Daytime=77-86 (halts at 95) 2. Night= 60-68 -->Cold damage <50 (may kill plants) -->Pollination 1. Night >72 (more critical - optimum range 59-68) -->Flower drop associated with temperature
Favorable Conditioins
-Wet, windy weather with realatively high temperatures of about 80-89F.
Southern Blight
-White mold 1. Preventative: soil drench
Pathogen Spread
-Wind-driven rain into tomatoes of foliage or wounds or insect punctures or fruit. -It can also be spread mechanically
Cutworms
-active only at night -control: -->remove grass and weeds -->Tin-Can method
Tomatillo
-close relative to the "husk tomato" -used mainly for sauces --> have husk around it like corn
Fruit Development : Tomatoes
-from anthesis (fertilization) -35 to 60 days from fertilization until mature. -From the time you transplant a tomato, it takes 60-90 days (about 72 is normal) -Breaker Stage : _<10% showing tannish-yellow, pink or red on surface. (pink on blossom end) Start Changing colors from bottom of tomato
Roma
-good for cooking -size of egg
Well drained soil
-pH 5.8-6.5 -Don't tolerate wet-feet -Need to rotate every 2-3 years

Tomato Insects
1. Cutworms 2. Thrips 3. Cornear Worm (AKA: Tomato Fruitworm) 4. Stinkbugs 5. Leaffooted Bugs (similar to stinkbugs) 6. Spider Mites 7. Aphids 8. Tomato Hornworm 9. Beet Armyworm
Pest Management : Tomato Insects

Types of Tomatoes
1. Fresh Market 2. Cherry 3. Grape 4. Roma 5. Tomatillo
Physiological Problems
1. Fruit Cracking 2. Puffiness 3. Catfacing
Tomato Nutrition
1. Lycopene: --> red pigment; antioxidant (fighting cancer) 2. Vitamin A: 3. Ascorbic Acid --> Vitamin C 4. Potassium K
Tomato Harvest
1. Mature Green -->For fried green tomatoes (shipping) -->Cut crosswise and if knife doesn't cut any seeds= mature 2. Vine Ripe
Fruit Cracking
1. Radical: -->Most common; on ripening fruit -->Often during rainy periods when temps are high; rains follow a long, dry period 2. Concentric:
Leaffooted Bugs
Control: -->Sprays
Tomato Hornworm
Control: -Pick off -BT: (Dust or spray)
Thrips
Control: -Resistant varieties -mulch -Heavy sprays early
Alphids
Control: -Wait for "crash," spray off with water hose; use insecticidal oil (sunspray) or insecticides -Insecticidal soap
Beet Armyworm
Killing cotesia wasp-->induces them!
Spider Mites
Love Hot Dry Weather -likes dirty plants -bronzing of leaves -avoid seven dust: can flare them control: -Miticides
Stinkbugs
Mid-Summer/ Fall pest; only when WARM Damage: -sunken-areas on shoulders Control: -Sprays -->Natural Pyrethrums=chrysanthemum (flower) *South Africa plant, grind them and separate the OIL. Will help with green stinkbug NOT brown
Tilage
Need good clean seed bed
Leaffooted Bugs
Similar to Stinkbugs control: -Sprays
Tomato Spotted Wilt Virus
Symptoms: -Bronze discoloration of young leaves -Plants may be stunted -Green fruit may show faint, yellowish-brown concentric rings Control: -Once plant has it there is nothing you can do. -Resistant Varieties -Reflective Mulches (silver)
Puffiness
Symptoms: -Outer wall is normal, but tomato is hollow inside; one of locular cavities usually empty
Cherry
determinates
Root Rots
soil-borne (rotate)
