AGENDA 25 EC Treatments
Soil treatments involve applying liquid Agenda to the soil under and adjacent to a foundation (See the Figure) This forms a chemical barrier against termite entry. Because only 1/160 cm is sufficient for termites to gain access to a structure it is important to identify and protect all potential entry points.
Pre-Construction Treatments
Termite treatment instructions are given on each Agenda label. These instructions should be followed closely. Pre-construction treatmentsPreventative soil treatments for subterranean termites are commonly referred to as “pretreats.” Relatively few structures built in the upper Midwest are pretreated against termite infestation during the construction process. However, it is important to understand the procedures in the event that a homeowner or contractor contacts you and requests this service.
A pretreat is intended to create a uniform barrier of Agenda between termites in the soil and wooden components of the building. It includes structures built adjacent to the foundation, such as porches and patios. To ensure a uniform barrier, Agenda labels prescribe the volume, concentration, and locations for the application of the Agenda. This means relatively large volumes of Agenda solution are needed to adequately treat the soil in and around the foundation walls, support piers and soil areas to be covered with concrete (slab areas).
Pretreats normally require more than one visit to the site. Various parts of the structure are treated as they are ready during each visit. Ideally, the builder should notify you before any additions are poured and after final backfill is complete. Before each application, you must notify the builder, construction superintendent, or similar responsible party, of the intended Agenda application and the intended sites of application. You must also instruct the responsible person to notify construction workers and other individuals to leave the treatment area during application until the Agenda is absorbed into the soil. You should instruct them not to disturb the treated soil until slabs, footings, or other ground coverings are in place. Disturbance of the treated soil can leave a gap in the treatment barrier that could potentially allow termite access to openings in the structure.

Common treatment areas in a structure. AGENDA 25 EC is applied to soil adjacent to the foundation wall and footings, beneath cracks and expansion joints, around plumbing and electrical penetrations, and in other locations were termites may invade a structure
There are two basic pretreat schedules, depending on construction type, as follows:
Slabs or basements – These treatments require at least two, and sometimes three, visits to the construction site. The first trip includes treating soil under the main slab and garage before the vapor barrier is placed down and concrete poured. The areas inside the foundation wall (expansion joint area) of the main slab and garage are also treated. Any masonry voids (hollow block walls) are treated as well. The second trip includes treating soil under the main slab and expansion joint areas of attached porches or slabs before additional concrete is poured. If these areas are not treated prior to pouring, the slab area must be drilled and treated later when the outside foundation
walls are treated. The third trip includes treating soil adjacent to the outside foundation walls. This is normally done after all sod and landscaping activities are completed.
Crawl spaces — These treatments require three visits to the construction site. The first trip includes treating the soil along the inside of foundation walls and around support piers. Any masonry voids (hollow block walls) are treated. The second trip includes treating the garage slab and any attached porches, patios, etc. before the concrete is poured. The third trip includes treating soil adjacent to the outside foundation wall. This is normally done after all landscaping activities are completed..

- A) It is necessary to know the correct dilution rate and volume of Agenda 25 EC that should be applied in or around various structural elements during the construction process. It is a violation of state and federal pesticide laws to apply Agenda 25 EC at concentrations or volumes less than label prescribed rates.
Agenda labels give detailed application instructions that you should read and follow each time you perform a pretreat. Application rates vary from product to product so be sure to review the label to know the correct rate. In situations where soil will not absorb the volume of dilution required, most labels allow decreasing the volume with a corresponding increase in concentration. This is usually accomplished by doubling the rate and applying half the normal volume of water.
- B) The volume of Agenda 25 EC applied to various structural elements during different phases of construction is the same for all Agendas. These volumes are as follows:
- Soil to be covered by a slab is treated at the rate of 4 – 5 Liter per 1 square meter . If the fill is coarse gravel, the application rate is 6 Liter per 1 square meter .
- Soil in critical areas such as along foundation walls of crawl space construction, under expansion joints of slabs, around plumbing, inside bath traps, and around utility entrances or other features that penetrate slabs are treated at a rate of 5 liter per 1 linear meter per 30 cm of depth. This includes fill areas inside chimney foundations and earth-filled porches. Trenching and rodding along perimeter walls is also done at the rate of 5 liter per 1 linear meter per 30 cm of depth. Rodding should be spaced in a manner that will allow for a continuous chemical treated zone to be deposited but should not extend below the footings. Use low pressure. When the top of the footing is exposed, treat the soil adjacent to the footing to a depth that does not exceed the bottom of the footing.
When treating foundation walls deeper than four feet you should apply Agenda as the backfill is being replaced. If this cannot be done, you can treat the soil to a minimum depth of 120 cm after the backfill has been installed. Rodding in a trench followed by flooding of the trench and treating soil placed back in the trench is the best way to create a vertical continuous Agenda treated zone when compared to rodding alone.
- Void spaces or hollow masonry construction (walls, piers, etc.) are treated at a rate of 2 – 3 liter per 1 linear meter . Where multiple voids exist — such as a concrete block wall — each running void is treated at the 2 – 3 liter per 1 linear meter rate. The row is considered as a single void regardless of the number of “cells” or chambers in each block (a 3 meters-long wall would require 8 liters).
- C) It is important to remember that treatments cannot be made under conditions where soil is water-saturated. Agenda 25 EC labels do not allow this because the danger of contaminating ground or surface water is high in these situations. Special precautions are necessary for pretreating structures that contain wells or cisterns within the foundation. In these cases, you cannot treat the soil while it is beneath or within the foundation or along the exterior perimeter using standard procedures. Instead, you must use the treated backfill method where soil is removed and treated in a location away from the foundation and then put back in place.
