Generation of Strawberries in Florida Monica Cooper

Slide 2

Field Preparation Clear all flotsam and jetsam Construct raised beds Fumigate 2 weeks after the fact, set transplants (15-16 in.) Transplant determination early season yield 3 assortments/field \'Sweet Charlie\' & "Camarosa"

Slide 3

Gulf Coast Research & Education Center Dover, FL

Slide 5

The Pathogens Botrytis cinerea Colletotrichum acutatum Colletotrichum gloeosporioides Colletotrichum fragariae Xanthomonas fragariae Sphaerotheca macularis

Slide 6

Gray form Botrytis cinerea Small, firm, light chestnut spots Fruit in the end secured with dark mass of mycelium Invades blooms, then taints developing natural product Postharvest

Slide 7

Management Leaf sanitation & plant dispersing Cultivars with littler calyxes Partially safe cultivars Biological controls Treat transplants Broad range fungicide on week after week premise Iprodione amid pinnacle blossom periods

Slide 8

Postharvest: Avoid overripe or harmed organic product Avoid damage Cool natural product Maintain in CO 2 rich air

Slide 9

Anthracnose natural product spoil Colletotrichum acutatum Round, firm, indented sores on natural product Pink, orange, salmon-hued spore masses Favored by warm temperatures & precipitation May bring about genuine misfortunes in nursery

Slide 10

Management rehearses Avoidance Resistance Use insignificant measures of Nitrogen Remove contaminated organic product from field Captan or Thiram (protectant) Quadris (azoxystrobin)

Slide 11

Anthracnose crown decay Colletotrichum gloeosporioides Colletotrichum fragariae Wilting & demise Temperature subordinate Warm climate & visit precipitation Reddish cocoa decay or streaking in the tissue of the crown

Slide 12

Management Preventative End of season expulsion of inoculum Resistant cultivars Benlate (benomyl) Topsin M (thiophanate-methyl)

Slide 13

Angular leaf spot Xanthomonas fragariae Angular, water doused leaf spots Translucent injuries Very impervious to drying up May get to be systemic

Slide 14

Angular leaf spot Prevention No safe business cultivars Copper containing bactericides

Slide 15

Sphaerotheca macularis Powdery mold White, web-like development Undersides of leaves Cool High dampness Severe in glasshouses & burrows

Slide 16

Management Clean stock Destroy leaves on which pathogen overseasons Protectant fungicide Resistant assortments (\'Sweet Charlie\')

Slide 17

The Arthropod Pests Twospotted arachnid vermin Armyworms Thrips Field cricket Sap insect

Slide 18

Tetranychus urticae 88% of cultivators Warm, spring climate Reduce yield Blooms and creating natural product

Slide 19

Spider parasite Clean transplants Beneficial bugs (30% of producers) Miticides undersides of leaves

Slide 20

Fall & Southern Armyworms Spodoptera fruqiperda Spodoptera eridania Larvae feast upon organic product & leaves Prefer youthful, creating leaves Nocturnal

Slide 22

Management works on Monitoring Sept. through Dec. Bacillus thuringiensis Methomyl

Slide 23

Flower thrips Frankliniella cephalica Wind-borne Rasp blooms Mistaken for fine buildup, shower smolder harm

Slide 25

Field cricket Gryllus firmus & G. rubens 2-5 months after beds secured Nymphs & grown-ups feast upon crowns & rub seeds from green natural products

Slide 26

Scouting Insecticides

Slide 27

Sap scarab Lobiopa insularis Minor concern Overripe, harmed berries Disseminate organic product decay pathogens Warm climate

Slide 28

Management Maintain sound organic product Don\'t leave overripe natural product in field Harvest all territories of field Scout Insecticides, just if there should arise an occurrence of populace blast

Slide 29

Beneficial Arthropods Predaceous vermin Sixspotted thrips Lady creepy crawly hatchling Minute privateer bug hatchling Hover fly

Slide 30

Phytoseiulus persimilis Orange, gleaming Faster than bug bugs Specialized predator of webspinning arachnid bugs Careful in selection of bug sprays

Slide 31

Sixspotted thrips Feeds on bugs, other little arthropods 3 dim spots on every forewing

Slide 32

Minute privateer bug hatchling Orius insidiosus Thrips, parasites, bug eggs, aphids

Slide 33

Hover fly Flower fly, syrphid fly Mistaken for organic product fly Distinguished by capacity to float & fly in reverse Adult pollinators Larvaepredaceous on aphid

Slide 34

Methyl bromide Methomyl (Lannate) Armyworm 65-80% grounds 3-5.2 times/season Fenbutatin-oxide Vendex Mite 31-61% real esatate 1.7-4.8 times/season Abamectin (Agri-Mek) Mite 68-83% of real esatate 2.5-3.4 times/season Diazinon Armyworm 24-35% of land 2.5-3.4 times/season Naled (Dibrom) 15% real esatate 2.2-3.1 times/season Insecticides & Miticides

Slide 35

More chemicals Carbaryl (Sevin) 11% of real esatate 2.6 times/season Bacillus thuringiensis When populaces of worms low 57-65% of real esatate 4.2-5.2 times/season

Slide 36

Several grasses & broadleaf weeds Managed chiefly by fumigation & plastic mulch Weeds issue in: Row middles Planting gaps Perimeter of field Nutsedge: Most troublesome Not oversaw by plastic mulch Weeds

Slide 37

Weed administration Cultivation of line middles Hand weeding Plastic mulches Cover crops, turfs, living mulches Fallowing Herbicides Applied to column middles Rotate herbicides because of changing weed populace more than 6-7 month season

Slide 38

Herbicides Paraquat (Gramoxone) Postemergence Annual broadleaf & grasses Top kill of perennials Non-specific, require shield to ensure berries 82-98% of real esatate, 1.7-1.9 applications/season Napropamide (Devrinol) Annual grasses & broadleaf weeds Not successful on set up weeds Not from sprout to reap 25% of real esatate, 1.23 applications/season

Slide 39

Sting Belonolaimus longicaudatus Root tie Meloidogyne spp. Foliar Aphelenchoides sp. Make plants more defenseless to: Drought Salt harm Other pathogens Fusarium sp. Pythium sp. Nematodes

Slide 40

Sting nematode Ectoparasite Most harming: Nurseries Transplants Sandy soil 25-30 o C

Slide 41

Symptoms: Well characterized outskirts Dead transplants Stunting, decay, torpidity Browning of leaf edges On roots: Overall, coarse appearance Tips harmed No new development Lack of feeder roots

Slide 42

Sampling At end of developing season When soil moist, not spongy or dry 10-20 tests at profundity of 6-10 inches Management hones: Preplant or postharvest Clean stock Destroy trim at end of season Fallowing with continuous culturing Cover edit Crop turn Chemical most normal Nematodes

Slide 43

Methyl bromide January 1, 2005 Soil fumigant Controls Weeds Nematodes soil-borne pathogens & bugs Telone C-17 or C-35 with Devrinol Telone EC Mulches, cover crops

Slide 44

Tunnel framework Decrease illness Increase early season yields Where water is restricting component \'Sweet Charlie\'
