NOTES TO THE PRESENTER OF
THIS PROGRAM You are most welcome to use any and all of these materials to give a local program. Most of the specifics were gathered from the items mentioned in the Bibliography. The chart is my own condensation of this information. These are my suggestions to you when presenting this program to local gardening groups: 1. Change the first three paragraphs to suit your personal credentials. 2. Take EMPTY CONTAINER samples of items to make the point of reading labels-household cleaners (CLOROX CLEAN-UP), repellents (OFF), and common garden chemicals (PREEN or ROUNDUP). 3. Make enough copies of the two Charts, and the two handout pages for all attending. GARDEN CHEMICAL SAFETY & GARDEN HEALTH 4. Make a few copies of the Bibliography to give to those who are REALLY INTERESTED in the sources or further information on the searchable web sites. This complete program will be available to all through the AIS Region 18 website at http://www.region18.com so you can refer them to that resource. 5. Its a dry subject so take bells, props, graphic pictures of iris borers, bugs, predators etc., to pass around and keep people awake. For my presentation, my husband dressed (exaggerately) in goggles, chemical mask, gloves, hat, while carrying a bar of Fels Naptha Soap and sprayer. 6. This also is a topic where there is an "overload" of information AND it changes daily, especially in the "Fact Sheet" area. Many articles recommend Brand Names that are no longer on the market (canceled shown in red) or too toxic (Class I or II) for me to recommend.
My credentials for this report are merely those of an enthusiastic gardener who is trying to garden safely both for the environment and myself. I inherited a troublesome shin condition that limits my exposure to most chemicals including soaps and detergents. In the course of dealing with garden pests and diseases, I have consulted many of my "expert" friends and acquaintances about what they use to deal with "garden yuckies" and found a great deal of disparity among methods. I then went to a variety of published sources to increase my understanding of health hazards involved with many of the "popular" chemicals and mixes and what the alternative might be. I want to share with you what I found and although I have some handouts citing sources and very professional sounding names and information, I again want you to realize I am NOT a toxicologist nor a chemist, just an interested gardener with probably too much information to process. My findings make sense to MY gardening habit and view of ecology but may not suit YOUR view of the overall scheme of things. I am sure you will not necessarily agree with all of my "works for me" conclusions, or perhaps even some of them. I am sure, however, you will agree that an informed gardener is a safer gardener.
1. TO AVOID PESTS AND DISEASES:
2. IDENTIFY YOUR ENEMY!!
3. THINK BEFORE USING PESTICIDES AND HERBICIDES
4. UNDERSTAND YOUR PESTICIDE PRODUCT
5. CONSIDER ALTERNATIVE TO PESTICIDES
1. Read and follow instructions on labels carefully (more is NOT better!) 2. Wear protective clothing including gloves and long sleeves and pants to minimize absorption of chemicals by the largest organ in the body the SKIN and a mask when dealing with chemicals that should not be inhaled. 3. Wash your body and clothes upon completion of application. 4. Do NOT use chemicals near children, pets, food or pet food containers, water, ponds or fish tanks or childrens toys. 5. Store all chemicals in their original containers with labels attached in a safe place, out of reach by children or animals and write the date of purchase on the container. 6. Dispose of all chemicals and containers according to label instructions. 7. Know the name of the active ingredients and the telephone number of the poison control center in case of accident. (Missouri 800-366-8888, Kansas 800-332-6633)
In the interest of safety, I suggest you keep this list posted in a predominate place in your gardening area or books.
I. INTRODUCTION
II. GARDEN HEALTH
III. GARDEN CHEMICAL
USES, ABUSES & SAFETY
C. Fundamentals for the Use of Garden Chemicals EPA sets the standards. Read the label BEFORE use. (See D. "Explanation of EPA Labels") Use chemicals ONLY for
the recommended application.
D. Explanation of EPA
Labels (Note to Presenter of this Program: Take EMPTY container samples of common Household Products with EPA labels CLOROX CLEAN-UP, OFF DEEP-WOODS INSECT REPELLENT V, etc. to demonstrate.) Product Name E. BASIC PRINCIPLES OF TOXICITY Just How Toxic is this Stuff? It is important to remember that many pesticides are toxic.
A. Pesticide Example in Selected Categories (refer to Toxicity Chart) Category I (* indicates potential for irreversible eye or skin damage) Orthenex*, Vendex*, Isotox*, Mavrik 2E*, Captan (only the dust or powder)*, Triforin EC*, Lime Sulfur*, Copper Sulfate* (if it contains 99% copper sulfate) Category II Category III Category IV B. Dangers of Pesticides all pesticides are toxic but not necessarily a hazard. Toxicity is how toxic it is to animals using the LD50 the greater the toxicity. For example, the LD50 of Diazinon is 350 mg/kg; the LD50 of Malathion is 2100 mg/kg. Diazinon has greater oral toxicity. It takes six times as much Malathion as Diazinon to kill you. Column 3 (of the Toxicity Chart) shows LD50 for man/oral. There are other EPA measures including oral/dermal, animals/birds/fish. Hazard toxicity and chance of toxic exposure-risk of poisoning/eye-skin damage. Persistence
how long it lasts. Pesticide persistence is often expressed in terms of half-life.
This is the time required for one-half the original quantity to break down.
Pesticides are divided based on half-lives: non persistent less
than 30 days; moderately persistent 30 to 100 days; and persistent
greater than 100 days.
IV. ALTERNATIVE TO
CHEMICALS INTEGRATED PEST MANAGEMENT (IPM) is a term that is gaining popularity. This does not preclude using sprays although a spray is chosen with minimal impact outside of the knocking down a specific pest. It is a temporary solution. Repeated spraying is proof that the gardens ecology is still imbalanced. Success with integrated pest management is based upon getting to know your garden, both the flowers and the other living things in it. Introducing a natural predator in your garden is often a permanent solution to a pest problem. It is also important to provide a suitable environment for the predators in your garden and to attract new ones. Many insect predators need an alternate food source, such as tiny flowers rich in nectar. Pest control materials are selected and applied in a manner that minimizes risks to human health, beneficial and non-target organisms, and the environment. Integrated Pest Management works best when you look at your garden as small ecosystem. After the planting is completed, your job is merely to help nature maintain a healthy balance. And often that is best done by leaving things to nature. The National Integrated Pest Management Network (NIPMN) is the result of a federal-state extension partnership dedicated to making the latest and most accurate pest management information available on the World Wide Web. Participating institutions have agreed to a set of standards that ensure science-based, unbiased pest management information.
Four Points of IPM:
What does "integrated" mean? The use of two or more pest management techniques (Inspection, Identification, Sanitation, Cultural, Mechanical, Biological and/or Pesticides) to achieve established pest management objectives. These are divided into three (3) groups Nontoxic controls, Less-toxic controls, and Most-toxic controls. Nontoxic Controls
Less-toxic Controls
Most-toxic Controls
Methods stress cultural, mechanical and biological controls with strict avoidance or limited use of insecticides, fungicides or herbicides unless naturally occurring or derived from natural sources. Cultural - cultivating and weeding disrupts weeds, buries insects or exposes them to adverse weather. Crop rotation, intelligent use of fertilizers and water can promote healthy plants, enhancing ability to resist disease. Interplanting with certain other plants may decrease certain insects. Plant disease resistant varieties and patronize hybridizers who do not "baby" their introductions. Mechanical hand weeding, mulching for weeds, slug traps Biological predators like praying mantis, ladybugs, (leave when food supply is gone) V: CONCLUSION
Other Notes to the Presenters of this Program During the research for this program, I read more carefully all of my favorite books on Irises, looking for citations to increase my knowledge on pests/diseases and chemicals. I purchased one book that is truly a gem of an addition to my library of gardening and its associated pitfalls COMPLETE GUIDE TO PEST CONTROL WITH AND WITHOUT CHEMICALS (Third Edition 1996) by George W. Ware from which I extracted some of the information in the chart I have prepared for this presentation. I also e-mailed many commercial growers that I respect to ask for assistance. I have copied portions of much e-mail on Iris-talk, the Internet list for Iris fanciers. I have amassed a wealth of articles, listed in the Bibliography along with general informational resources on growing/culture/garden chemicals. I urge you to read them. If you have a favorite resource that I did not use, please let me know as I hope this program will span a wide range of experience and knowledge. While doing the charts, I gathered some of the information from the EPA records (which may or may not be up-to-date). Some of the Standards that went to effect in 1996 are just now being implemented and others are scheduled for effective dates in the near-future so the HAZARD designation of chemicals is current to the best of my knowledge. The Hazardous for MY use were not included in the charts. Organic/natural ingredients are not necessarily better/effective but I believe in IPM and doing all the "least chemical method" as the first solution to pests and diseases. There are 893 active AIs There are 11633 active products In other words, use your own judgment but I hope this information makes you able to judge better!
