# Ornamentals & Turf Course

This year has been unique for everyone. All of us have been impacted in one way or another. We sincerely hope that you and your family are doing well and the pandemic has not touched you or your family. We at UConn Extension have been striving to put this course online for your convenience. While we understand that an online course is simply not the same as in person, this is where we are in the world today. We will certainly miss the interaction we have with all of you in the classroom as well.

There are some advantages to having an online course though, first you can work when it’s most convenient for you. You can also take the course in small chunks rather than sitting through a 3-hour lecture. You don’t have to leave your job or business to take the course either.

This Short Course is an in depth review of the information necessary for studying and fulfilling the requirements of the Ornamental and Turf/Golf Course Superintendents State of Connecticut Supervisory Pesticide Applicator Certification exam. A student completing all the modules, working through the quizzes, and studying resources materials independently should be able to successfully pass the examination, both written and oral state exam. Expect to spend at least 8 hours on each module.

Class topics are: Pesticide Laws and Regulations, Pesticide Safety, Botany and Ornamental Identification, Plant Pathology and Ornamental Plant Diseases, Entomology and Insect Pests of Woody Ornamentals, Area and Dosage Calculations, Turf Management and Weed Management. Each class begins with a basic overview of the science then takes an in-depth look at specific pests, their biology and control.

We have developed the course into 8 modules. Each module is broken down into Parts. Each part begins with learning objectives followed by slides with a narrative. PDFs of the slides are available for printing. Each Part will close with a summary and quiz on the contents of the part just viewed. Please take the quizzes seriously and take the time to write out your answers, as this will help you retain the important points from each Part and be useful for studying for the final exam as well as the state exam.

Each week on Tuesday evenings at 5:30, we plan to introduce a new module for you to work through during the week. The following Tuesday we will do a short debrief of the module you just completed and introduce the next module, again followed with a debrief the next Tuesday and so on for 8 weeks.

This does not include the required Pesticide Applicator Training Manual, (aka “The Core Manual”), which can ordered from UConn MarketPlace under the College of Agriculture, Health and Natural Resources Extension at:

An additional resource which is very highly recommend by CT DEEP, and is free from the website below it is called, “Turfgrass Nutrient and Integrated Pest Management Manual”, edited by Tim Abbey. This is really is a must read and necessary resource: http://cag.uconn.edu/documents/Turfgrass-IPM-manual-s.pdf

There is also an optional manual called “Ornamental and Turf, Category 3 manual” available from Cornell, it cost $41.00 plus shipping and handling. https://www.cornellstore.com/3.-Ornamental-And-Turf Check for used copies of these books with your colleagues or online, yes, even check Amazon. ### Register for the online course here.

# Pesticide Law Primer Developed for Schools

Pesticide Law Primer Developed by UConn Extension for Connecticut School Grounds Managers, Superintendents, Teachers, and Members of the School Community

UConn Extension, with the CT Department of Energy and Environment (CT DEEP), has developed a series that explains and clarifies Connecticut’s pesticide restrictions on school grounds.

In 2010, Connecticut state legislation banned the application of all pesticides registered with EPA, and labeled for use on lawn, garden, and ornamental sites, on the grounds of public or private daycares and schools with grades K-8. The law was amended in 2015 to allow the use of horticultural oils and microbial and biochemical pesticides.

Since enactment of this legislation, weed control on school ground properties has been a significant challenge for school grounds managers. Although the law is nearly 10 years old, widespread understanding and awareness of the law remains elusive. UConn Extension’s primers aim to break down the most essential details of the law for grounds managers, administrators, parents, guardians, teachers, and other members of the school community.

Vickie Wallace and Alyssa Siegel-Miles, of UConn Extension, with the assistance of Diane Jorsey, of CT DEEP, created three versions of the primer: a brochure for the school community; a more detailed primer for school administrators, and longer primer that includes management information for school grounds managers.

• Which school locations are affected by this law?
• Which pesticides are banned?
• Who can apply minimum risk pesticides on school properties?
• Are exemptions to the law permitted for emergencies?
• Are there pesticide products that are permitted for use on K-8 school properties?
• How must a school notify the school community, including parents, of pesticide applications, whether minimum risk or emergency?
• Can playing fields, grounds, and lawns be managed without the use of pesticides?

# Natural Pesticide Issues

As the gardening season gets underway, lots of homemade weed-killer “recipes” are cropping up on social media, usually containing some combination of vinegar, Epsom salts, and Dawn dishwashing soap. These are often accompanied by a comment such as “no need for pesticides or herbicides!” It may feel good to use familiar household items to control pests and weeds in your garden, but it’s important to understand the science behind such mixes – and the potential risks.

First and foremost, these mixtures ARE pesticides or herbicides. They are intended to kill a pest, in this case weeds.

Now, let’s look at the science:

Vinegar is an acid. At the right concentration, it damages by burning any part of a plant it comes in contact with. If the plant is in the ground, it does NOT get the root; many plants will grow back. It is non-selective, meaning it will damage any plant it touches, including desired ones. Household vinegar is 5% acetic acid; to be effective on anything other than tiny seedlings the concentration needs to be at least 10%. Horticultural-grade vinegar is 20% and can carry a “Danger – caustic” signal word, which is stronger than many other herbicides on the market.

Salts work by desiccating plants – again, all parts of the plant it touches. Salts, however, build up in the soil and can harm desired plants nearby. Since most homemade recipes need repeated application to be effective, the salts will build up. Epsom salts are touted because they contain magnesium instead of sodium, but too much magnesium will interfere with phosphorus uptake.

Dawn detergent is not a naturally-occurring substance. It, like any soap, is used as a sticker agent, helping the other materials stay on the plant longer. Like many detergents, it contains methylisothiazolinone, which has acute aquatic toxicity and 1,4-dioxane, which is a known groundwater contaminant with carcinogenic properties.

These may be do-it-yourself recipes, but they definitely are not natural.

An additional issue with home recipes is the variability of the mix. Many don’t even have specific measurements. Also, because home remedies are often perceived as “safer”, a person may choose to increase the concentrations, changing the potential environmental risk.

Many of these recipes do indeed kill – or at least reduce – weeds and unwanted vegetation. But they also have collateral impacts, some of which may be significant.

The garden center shelves have changed in the last several years. There are now many naturally-derived pesticides on the market, which have been tested for effectiveness, are labelled as to their environmental impact and deliver a consistent product every time. They generally are safer to use and pose less environmental risk than many of the older synthetic materials – the same goal of homemade mixes. Look for products that are OMRI certified. The Organic Materials Review Institute is a nonprofit organization that provides an independent review of products, such as fertilizers and pest controls that are intended for use in organic production.
