New Exam Review and CEU Class Offered in Panama City: May 10-11, 2018

New Exam Review and CEU Class Offered in Panama City: May 10-11, 2018

In December of 2017, a new Commercial Lawn & Ornamental Pest Control Operator exam was launched in Florida. This updated exam covers materials found in two new manuals not previously recommended as study guides: “Identification Guide to Common Florida Lawn and Ornamental Weeds,”  and “Lawn and Ornamental Pest Management.”. Photographic pest identification including knowledge of life cycle have nearly tripled when compared to the prior exam.

Because this exam is a statewide license, many pests may not be familiar to industry professionals in NW Florida if they are more commonly found in peninsular or South Florida.

The new exam also includes Green Industries Best Management Practices (GI-BMP) topics, Florida Statutes, Administrative Rules, safety concepts from “Applying Pesticides Correctly” and label reading – both fertilizer and pesticide calculations and label interpretation.

The paper exam has been offered twice in Apopka since the launch last year with pass rates below 50% at both sessions.

Panhandle Horticulture Agents in partnership with FDACS (Florida Department of Agriculture and Consumer Services) will be holding a review class May 10-11, 2018, in Panama City. This class is designed to reinforce lawn and ornamental pest control concepts with a focus on newly introduced material for the CPO Commercial Lawn & Ornamental exam, but is not a replacement for independent study.

Exams will not be given in conjunction with this class. Anyone interested in taking the CPO Commercial Lawn & Ornamental exam is still required to meet all mandated qualifications of education and/or experience. Applicants must then apply online https://aesecomm.freshfromflorida.com/ with FDACS to obtain a voucher and schedule the test with a local Extension office.

This class will also provide CEUs for current license holders in the following categories (please check 2018 CEU Commercial L&O Flyer for dates – not all CEUs available both days): Commercial L&O, Limited L&O, LCLM, O&T, Private Ag, Limited Urban Fertilizer. Core CEUs will be available both days.

Registration is customized based on attendees needs as one-day of your choice or two-day. If you plan to take the Comm. L&O Exam, it is strongly encouraged that you attend both days.

Cattle Grazing on My Trees…

Cattle aren’t really grazing on the trees (this time), but tree cattle (a.k.a. bark lice) are grazing on the trees.  The scientific name for tree cattle is Cerastipsocus venosus.  Adults have shiny black wings that are held at a sharp angle resembling an old style camping tent or an F-117 Nighthalk stealth fighter.  Wingless adults also exist.

The nymphs have an ovate abdomen with dark gray and light yellow banding similar to a honeybee.  A related species, Archipsocus nomas, is known to produce unharmful webbing that covers the trunk and branches of trees, but not the leaves.

These insects are usually seen in a colony containing a mixture of nymphs and adults.  Unlike hair lice, bark lice are not parasites and are classified as beneficial insects.  Unlike most beneficial insects, they do not feed on other insects.  Instead, they clean the bark by eating excess accumulations of fungi, algae, lichens, dead bark, and other nonliving material.  Tree cattle are not bark borers and do not eat leaves or living bark.

They are often seen on crape myrtles, but have been reported to graze on oaks and Bradford pears.  Bark lice are more prevalent during hot and humid summer months.

Tree cattle are classified as beneficial, therefore no management is required.  Because clientele may consider the term beneficial insect to be an oxymoron, it is important to supply supplemental educational materials to back up your claim.  Publications are available from Clemson University and Auburn University.

Muhly Grass Pest

Muhly grass (Muhlenbergia capillaris) is a generally pest free plant in our area, however, we are seeing the native mealybug, Stemmatomerinx acircula, on plants in various landscapes. Insects are on the leaves and are grey with white wax that may have some filaments. You may also see long ovisacs on the leaves which contain eggs and crawlers. The native fakahatchee grass may also be a host.

The common practice of right plant, right place does not always prevent the mealybug infestations on muhly grass. Specimens in both full and shade can be affected, as well as mass plantings and those spaced out. At this time, there is not a lot of information on why some plantings are heavily infested and others are not.

Since mealybugs are piercing sucking insects, there may be some browning of leaves, especially on less vigorous plants. You may have to remove and destroy plants that are heavily infested and declining. In situations where treatment is warranted you may choose a systemic insecticide or oil spray to keep plants looking more attractive.  As the landscape manager, you will need to decide what is an acceptable threshold for this pest.

Integrated Pest Management – Accurate Pest I.D.

Using an Integrated Pest Management (IPM) approach to landscape management has been an integral part of the green industry for many years. The strategies help to make pest control more efficient by incorporating multiple methods and being flexible enough to make changes where needed.

One of the most critical steps in your IPM plan is monitoring and correct pest identification. If the pest is not identified correctly, then any steps taken to control that pest will be ineffective and may also mask the original problem making it harder to get a correct diagnosis.

Correct identification does not stop at naming the pest in question. More research needs to be done to choose the appropriate management methods.  Some key questions to answer are:

• What are the primary hosts in this landscape?
• How can we manage the landscape to make the pest less successful?
• What is the life cycle of the pest?
• How/where does it reproduce?
• At which stage of the life cycle are we likely to get the best control?
• Are there different strategies based on life cycle stage?

Answering these questions will help you choose appropriate control methods whether cultural, mechanical, biological, or chemical. Remember to always keep good records and modify your plan as needed.
