New & Revised Lawn and Garden publications, May 2016

This edition of New Lawn & Garden #EDISpubs for May is has information on protecting your ornamentals from metsulfuron herbicides, a salt-tolerant native tree for coastal landscapes, and Zika vector control.


Lawn & Garden

Creciendo Papas en el Jardín de su Hogar en la Florida

The Irish potato is a cool-season crop. A recently grown and harvested potato exhibits different flavor profiles from one that has been in storage or on a grocery shelf for an extended period. For example, in storage, the starches in potatoes convert to sugars, resulting in a less desirable texture and taste. “New” potato flavor can be achieved in the home garden by following a few growing recommendations. This is ten-page fact sheet is the Spanish language version of
HS933 Growing Potatoes in the Florida Home Garden. Written by Christian T. Christensen, Joel Reyes-Cabrera, Lincoln Zotarelli, Wendy J. Dahl, Doug Gergela, Jeffery E. Pack, James M. White, and Chad M. Hutchinson.

Metsulfuron-Methyl-Containing Herbicides Potentially Damaging Ornamentals when Applied to Turfgrass

Metsulfuron-methyl, also known as MSM, is an herbicide that is used to control broadleaf weeds and certain grass weeds. It provides effective control of some of the most problematic turfgrass weeds, such as wild garlic, Florida betony, dollar weed, and small Virginia buttonweed. Metsulfuron-methyl is absorbed by plant foliage, so if landscape plants come into contact with the spray or drift they can be injured. This four-page fact sheet describes the potential problems with metsulfuron herbicides, the areas most sbsceptible to damage, how to diagnose injury, and how to reduce damage. Written by Chris Marble, Jason Smith, Timothy K. Broschat, Adam Black, Ed Gilman, and Celeste White and published by the School of Forest Resources and Conservation Department.

Pest Identification Guide: Chilli thrips Scirtothrips dorsalis Hood

Chilli thrips transmits the ilarvirus Tobacco streak virus (TSV) and the tospoviruses Groundnut bud necrosis virus (GBNV), Groundnut chlorotic fan-spot virus (GCSFV), and Groundnut yellow spot virus (GYSV). This species primarily feeds on young, tender foliage. Feeding on foliage may result in silvering leading to necrosis, leaf curl (upward), distortion, and defoliation. Feeding on the fruit may cause scarring, discoloration, and the formation of corky texture on the fruit. Learn to identify the chilli thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Pest identification Guide: Florida flower thrips Frankliniella bispinosa (Morgan)

The Florida flower thrips is a known pest of blueberry but its status in other crops is unclear. Florida flower thrips transmits Tomato spotted wilt virus and possibly other tospoviruses. This species is primarily a flower feeder, so most damage would be expected on the flower or fruit. Learn to identify the Florida flower thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Pond Apple: A Tree Species Adapted to Salt Stresses

Soil salinity is a naturally ocurring problem for growers, gardeners, and homeowners in Florida. As sea-levels rise, seawater intrusion causes salt stress to plants grown in coastal lowland areas. This three-page fact sheet introduces a salt-tolerant species, pond apple (Annona glabra L.), which has great potential to be used in high-salinity coastal landscapes. Written by Guodong Liu, Yuncong Li, Kimberly Moore, and Kim Gabel and published by the Horticultural Sciences Department.

Zika Vector Control for the Urban Pest Management Industry

Zika is a mosquito-transmitted virus that has recently spread to the Americas. Zika virus (ZIKV) was discovered in 1946 in Africa where it was isolated from a Rhesus monkey in the Zika forest of Uganda. In 2007, a disease outbreak occurred on the Yap islands in Micronesia, and in 2013, an outbreak occurred in French Polynesia. In 2015, a large outbreak occurred in Brazil, and ZIKV has since spread through the Americas. As of April 18, 2016, 15 counties in the state of Florida had reported travel-associated Zika cases. This seven-page fact sheet provides an overview of ZIKV, including its incidence and distribution, transmission and symptoms, and the connection between zika virus and infant microcephaly. This article also explains the biology and identification of the mosquito that vectors the virus with a focus on how to manage the vector using inspection, larviciding, adulticiding, monitoring, and personal protective equipment. Written by Casey Parker, Roxanne Connelly, Dale Dubberly, Roberto Pereira, and Philip Koehler and published by the Entomology and Nematology Department.
