The Herbicide BankFrom the opening of the ‘Bank’ in 2000, the program has provided chemicals at no charge to public land managers for conducting invasive plant management on conservation land. Funding has varied over the years, but to date the Bank has provided $14,790,500 of chemicals that were used to treat invasive plants on 730,000 acres of public conservation land. For private contractors, chemicals typically comprise up to 10% of the total project cost-their major cost being labor. Thus, in comparison, that $15 million of “free” chemicals has saved the Uplands Program ten times that amount in “free” labor. Now that’s a bargain!

Introduction

How do I request chemicals from the Herbicide Bank?Requests must be submitted to the Herbicide Bank using the Request Form (Appendix I). All requests are subject to approval by the Uplands Program administrator. Approved requests will be filled in the order they are received, as funding allows. The Herbicide Bank does not accept single orders from individual site managers. An Annual Summary Report (Appendix II) must be submitted with or prior to the Request Form. The report should summarize use of Bank-provided chemicals in the previous fiscal year(s). One report should be completed for each management unit (park, forest, etc.), but the reports may be bundled as part of a regional request.You must say in your request if you need a liftgate, forklift, or similar equipment to unload an order. This is not standard equipment for most delivery trucks and requires prior planning.

Who may request chemicals from the Herbicide Bank?Any agency staff responsible for invasive plant control activities on a PCL may use the Bank, whether or not prior plant control operations were funded by the FWC (or DEP) Uplands Program. All agency requests for chemicals must be coordinated internally at the highest practical operational level. State natural resource agencies are typically divided into Districts or Regions. So, for example, the Florida Park Service would submit one request for all of the parks within District 1. Ideally, a request will include the chemicals needed for one year of control operations, which will shipped to a single central facility. If storage is an issue, orders may be split into two deliveries within one fiscal year. Cities and counties are more likely to have a central maintenance yard where all chemicals can be stored, so a request should be submitted by the Director of Operations, or equivalent. Ideally, department heads of parks, preserves, greenways, or similar agencies will coordinate their needs before submitting a request.The intent of this procedure is for land managers to cooperate, coordinate, and collaborate with each other to plan for their management needs on a landscape level. Vendors deliver orders at their cost (factored into their bid prices), so a coordinated delivery system will be more cost-efficient for them, which will lead to better pricing for the State in the future.

What projects are eligible for requesting chemicals from the Herbicide Bank?Any site manager conducting maintenance control of FLEPPC Category I and II invasive species on a PCL is qualified to request chemicals from the Bank. Any initial control of Category I or CISMA-listed EDRR species may also be eligible.

What chemicals are eligible for requesting from the Herbicide Bank?This ITB award is a statewide agency term contract that covers most common herbicides and adjuvants. Chemicals that are not typically used for natural areas management (e.g., basagran, carbaryl, dicamba) are not provided by the Bank. Aquatic plant control is not authorized under the Uplands Program; however, some aquatic chemicals (e.g., imazamox) are increasingly used in terrestrial settings and may be eligible for request.

Herbicide Bank Operational Procedures

For state fiscal year 2018-19, the IPMS budget was reduced by $2 million. This reduction affects all programs, including the Herbicide Bank. Thus, the availability of chemicals for this year will be largely restricted to priority herbicides and no adjuvants other than basal (bark) oil. These chemicals are eligible for request: 2,4-D, diquat, glyphosate, imazamox, imazapic, imazapyr, Milestone, and triclopyr. This includes aquatic and terrestrial labels and amine or ester formulations. Method 240SL may also be available, on a limited basis.

Remember: You are responsible for following all label directions when using any product. The label is the law!

Other regulations may also apply, such as Florida’s recent organo-auxin rule (Appendix III).

What do I do with all these empty chemical containers piling up on my site?RECYCLE! USAg Recycling provides a free service through the Ag Container Recycling Council for this very purpose. Information is included in Appendix IV, or you can check their website: www.usagrecycling.com

Can other divisions or agencies “piggyback” or use this ITB?Yes, FWC ITB 17/16-128 is a statewide agency term contract. All FWC employees are required to use this contract for purchasing awarded chemicals. For FWC, use of the purchasing card is okay, unless your internal procedures say otherwise. P-Card users should obtain supervisor approval for the purchase prior to the use of the card for payment. An APR is required to be submitted along with all supporting documentation.

Other public agencies may choose to use this ITB, but it is not yet an alternate source contract (ASC). State agencies must first get DMS approval to “piggyback” on this ITB award (or ask them to make this an ASC). The State of Florida is tax-exempt. Public agencies should check invoices for added sales tax. Your agency may be asked by the vendor to provide a tax-exempt certificate. All bid prices are FOB, so there should not be a delivery/freight charge on any invoice, either.

I want to purchase chemicals not offered by the Bank, or for uses not eligible for the Bank. Who do I contact?

Organo-auxin (phenoxy) herbicides were first developed during the 1940s and have been used extensively in the United States since then. This group of chemicals has found a place in weed control schemes for peanut, corn, small grains, sugarcane, turf, pasture and forage crops and many other areas. On a worldwide basis more phenoxy herbicides are used than any other class of herbicides presently manufactured. The phenoxy herbicide group’s unique ability to remove broadleaf weeds from grass crops has been exploited for successful weed control in many areas.

Organo-auxin herbicides have been formulated in a number of ways with each formulation possessing certain characteristics. Amine and ester formulations have been the most popular although other forms of phenoxys do exist. As a general rule ester formulations are more active than amines. This difference in control activity has made ester formulations very popular due to the fact that about one half the rate of the amine formulation could be used and achieve the same weed control level. Therefore, growers could buy less total herbicide in the ester form to do the same job as a larger amount of a phenoxy in the amine form.

Although ester formulations are more active herbicidally than amine formulations, they do have serious drawbacks associated with their use. Specifically, ester formulations

are typically very volatile and possess the ability to move away from the target site up to several days after the initial herbicide application has been made. Volatilization problems have led to the complete destruction of nearby sensitive crops if weather conditions were favorable for volatilization to occur. Sub-lethal doses of organo-auxin herbicides cause very visual effects, indicative of hormonal action (Figures 1 – 4). Due to volatilization problems, many states have totally banned the use of high-volatile ester formulations and discouraged use of lower volatile esters in sensitive areas. Florida is one such state with these regulations. Due largely to phenoxy herbicide applications in south Florida on sugarcane and drift or volatilization to nearby tomato crops and their subsequent destruction, the Florida Department of Agriculture and Consumer Services (FDACS) enacted the Organo-Auxin Herbicide Rule (Table 1). This rule applies to the application of organo-auxin herbicides anywhere within the state. It is the intent of this publication to clarify and disseminate the Florida Organo-Auxin Herbicide Rule to interested growers and applicators.

A suggested recordkeeping form developed by FDACS is available for applicators of organo-auxin herbicides to record their data. Although this specific form is not required, it does contain spaces for providing the required data to be recorded (Figure 5).

Table 1. FLORIDA ORGANO-AUXIN HERBICIDE RULE NO. 5E-2.033 ORGANO-AUXIN HERBICIDESRestrictions and Prohibitions

1. Synthetic organo-auxin herbicides: The Synthetic organo-auxin herbicides are defined as herbicides which produce hormonal auxin type effects on plants similar to the effects of 2,4-D. These herbicides include:

2,4-D 2,4-Dichlorophenoxyacetic acid, in all forms;

MCPA 4-chloro-2-methylphenoxyacetic acid, in all forms;

2,4-DP 2-(2,4-Dichlorophenoxy) propionic acid, in all forms;

MCPP 2-(2-methyl-4-chlorophenoxy) propionic acid, in all forms;

MCPB 4-(2-methyl-4-chlorophenoxy) butyric acid, in all forms;

Dicamba 2-Methoxy-3, 6-dichlorobenzoic acid, in all forms;

Triclopyr (3,5,6,-Trichloro-2-pyridinyl) oxyacetic acid, in all forms;

2. Sale and use of highly volatile forms of organo-auxin herbicides in the state is prohibited except for those products labeled for use as plant growth regulators on citrus. Highly volatile organo-auxin herbicides include the methyl, ethyl, propyl, isopropyl, and butyl esters of 2,4-D, etc.

3. Based upon the wind speed and direction at the time of application, the distance which must separate the closest edge of the area to be sprayed from susceptible crops is listed below. Susceptible crops are defined as commercially produced plants or crops that may be damaged when exposed to low concentrations of organo-auxin herbicides. Users of organo-auxin products on citrus as plant growth regulators are exempt from the wind speed restrictions below provided they adhere to the restrictions appearing on the product label.

Wind Speed Aerial Equipment Ground Equipment

0 - 3 mph ½ mile downwind 1/8 mile downwind

½ mile crosswind

50 feet upwind

3 - 6 mph 1 mile downwind 1/4 mile downwind

½ mile crosswind

50 feet upwind 5 feet upwind

Above 10 mph Prohibited Prohibited

Note: “Crosswind” means wind from a direction 90 degrees (+/-10 degrees) to a line drawn between the proposed treatment site and a susceptible commercial crop site.

4. Wind speed will be measured at the crop site or up to two miles away. Wind speed measurements will be taken at spray boom height for ground application and at least six feet above the ground for aerial application. The measurement site will be located so that structures, plants, or terrain features do not interfere with the accuracy of the reading. Wind direction will be estimated as accurately as possible by the person taking the wind speed readings. THE APPLICATOR OR HIS REPRESENTATIVE SHALL TAKE AND RECORD WIND SPEED AND DIRECTION READINGS BEFORE SPRAYING STARTS AND ONCE EVERY HOUR OF THE SPRAYING OPERATION. A reading shall consist of an average of three measurements taken within a five-minute interval. These measurements shall be taken by rotating and positioning the anemometer into the wind in such a manner as to obtain the maximum wind velocity measurements which will be used to calculate the average reading. An anemometer accurate to within +/-10% shall be used to take the wind speed measurements. Possible sources to obtain wind meters are listed in

5. Applicators should minimize the production of droplets with mean volume diameter less than 200 microns in diameter regardless of spray equipment utilized. When utilizing boom application equipment on the ground, flat fan nozzles or their equivalent should be used and application pressures shall not exceed 35 pounds per square inch. Applications of organo-auxin herbicides on citrus as a plant growth regulator utilizing air blast sprayers are exempt from the requirements of this section.

5Florida’s Organo-Auxin Herbicide Rule - 2015
