Slide 1


Slide 2

PALMETTO WEEVILS Drawn to focused on palms in sub-tropical profound south (for the most part cabbage & Canary Island Date palms). A few animal varieties spread nematode in Central and South America and Caribbean.

Slide 3

Palm weevils

Slide 4

Symptoms & Treatment Adult females lay eggs in leaf bases of crown, hatchlings burrow into heart, obliterating the palm. Crowns of influenced palms topple over or "deadhead". Lessen transplant stretch Preventative shower of Lindane or Dursban connected at and a couple of weeks after transplant.

Slide 5

Reducing Transplant Stress Transplant early spring or summer - soil beneath 65C demoralizes new root development. Expel 1/2 or more of leaves at time of burrowing to diminish water misfortune from transpiration. Ideal waste. Abstain from transplanting further than initially developed. Micronutrient foliar splash since root ingestion is constrained.

Slide 6

ROYAL PALM BUG Troublesome nuisance in Florida and Caribbean. Pervasions increment in Spring and Summer after a mellow winter. Bolsters on youthful leaves getting in the middle of folds of rising leaf.

Slide 7

Treatment Three types of bugs have been found to go after illustrious palm bugs, and proposed that they, alongside overwhelming downpours, are central point in the normal control of the species. whether populaces of these productive bugs are controlled by arachnids and rain alone is still open to address. Strategy not being used.

Slide 8

Treatment A moderately new bug spray found by Bayer, imidacloprid, demonstrates guarantee. It can be connected without an uncommon utilize allow. low mammalian lethality - oral LD50 rates as 1858-2591 mg/kg and the dermal LD50 rate as >2000. Long haul viability because of soundness in soil, yet may take weeks for root soak to produce results.

Slide 9

PALM APHID Female gets to be stationary like a scale shaping a particular waxy ring around it. Intensely pervade youthful leaves and emit honeydew whereupon dirty form will develop.

Slide 10

Sooty Mold Fungus that encourages upon "honeydew" from aphid, scale, mealybugs. Meddles with photosynthesis. Control honeydew delivering creepy crawlies.

Slide 11

Leaf Spots Helminthosporium, Anthracnose, Stigmina, Pestalotiopsis All cause spots, some union and frame cursed zones. Effortlessly spread by utilization of overhead water system.

Slide 12

False Smut Significant issue of scene palms amid substantial precipitation. Grayish-dark fruiting bodies on both sides of leaf. Copper based fungicides and maneb or mancozeb successful if connected in early stages.

Slide 13

Phytophthora root decay Also causes leaf spots and bud spoils. Dousing soil with metylaxyl lessen populaces of this organism. Foliar connected fosetyl aluminum will translocate to foundations of palm. Avoid overwatering.

Slide 14

Ganoderma Butt Rot Serious and hopeless malady of more seasoned palms. Advances from more seasoned leaves upward which turn chestnut and hang from the storage compartment. Wounds on lower trunk permit passage of growth.

Slide 15

Ganoderma butt spoil Fruiting body an obvious section or conch. Quick spread and tireless in soil. Evacuate and pulverize affected palms and conchs. Disinfect soil and replant expansive leafed trees (not defenseless).

Slide 16

Fusarium shrink Frequent in California and beginning in Florida. Uneven decrease in covering. Exchanged from tree to tree by pruning instruments, so they ought to be cleaned between employments.

Slide 17

Coconut Lethal Yellowing Incurable malady brought about by a mycoplasma-like life form. Vector - Leaf container. Yellowing and kicking the bucket of clears out. Maintain a strategic distance from by planting safe assortments. Decay incidentally suspended by anti-infection infusions.

Slide 18

Spider Mites Biggest issue in nursery creation. Substance controls reducing. Best controlled by savage bugs: Phytoseiulus persimilus Neoseiulus californicus

Slide 19

Spider Mites persimilus is a snappy acting parasite and is typically discharged ititially. californicus is slower moving "bat tidy up" and discharged later. These strategies work better in nursery where plants are tip to tip.

Slide 20

Pest Management Approaches City of Hollywood, Florida, Alice Cohen - nursery palm generation. Focal Florida augmentation specialist for University of Florida, Liz Felter South Florida expansion operator for University of Florida, Bill Schaal - nursery and field developed palms.

Slide 21

City of Hollywood Palms in scene, medians, parks, and so forth. Palm weevil every so often an issue - just treat when they see harm. Must shower in crown. Safe cleansers and oils. Safe assortments (deadly yellowing) Stopped planting impatients around trees since water req. is high - advances contagious pathogens. Sadly, plants are chosen by non-horticulturalists for stylish esteem. Some are tropical, req. parcel of water which advances illness. No natural control utilized.

Slide 22

Central Florida Greenhouse Production Predatory parasites for creepy crawly vermin. #1 bug. Scale, #2 bug - no biocontrol. Utilize Dimethoate or Marathon (systemic). Deposit up to 60d, so can't discharge biocontrols amid this time. Scouting and record keeping of adolescent sitings. Utilize logbook documentation in dz. anticipating.

Slide 23

Companies, for example, Glades Crop Care give a scouting administration, yet charge around 600/mo. not seen as financially savvy by most. Most scouting organizations have practical experience in agronomic yields, not ornamentals. IPM specialists uncommon. Florikan, provider of developing supplies, concentrate on IPM items. Pheremone attractants, Opogona (catarpillers for nematode control), pred. vermin, and so on
