Applications & Uses
- Markets
- Applications
- Application Technique
- Fungicide Target Species
- Mode Of Action
Terraclor 400 works by inhibiting lipid peroxidation. Terraclor 400 works primarily as a preventative agent through contact activity, and should be applied before disease symptoms appear in order to achieve optimum results. However, Terraclor 400 has curative properties as well.
- Use Sites
Terraclor 400 may be used on ornamental plants grown in commercial greenhouses, shadehouses, and nurseries. Terraclor 400 binds rapidly to organic matter. Irrigation will not wash it off.
- Application Rates
Terraclor 400 should be soil applied as a drench or incorporated thoroughly into the soil for best results. As a drench, apply 6-12 fl. oz. per 100 gal. over an area of 400 to 800 sq. ft. depending on depth of control desired. See label for more details.
Terraclor 400 may be applied as a foliar spray for control of magnolia leaf spot.
Drench Solutions for Rhizoctonia
Solutions should be applied as a drench directed at the soil surface.

If these wastes cannot be disposed of by use according to label instructions, contact your State Pesticide or Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for guidance.
CONTAINER HANDLING: Non-refillable container: Do not reuse or refill this container. For containers 5 gallons in size or smaller: Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow begins to drip. Fill the container 1/4 full with water and recap. Shake for 10 seconds. Pour rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to drip. Repeat this procedure two more times. Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or disposal. Insert pressure rinsing nozzle in the side of the container, and rinse at about 40 PSI for at least 30 seconds. Drain for 10 seconds after the flow begins to drip. For containers larger than 5 gallons:
Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank. Fill the container ¼ full with water. Replace and tighten closures. Tip container on its side and roll it back and forth, ensuring at least one complete revolution, for 30 seconds. Stand the container on its end and tip it back and forth several times. Turn the container over onto its other end and tip it back and forth several times. Empty the rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Repeat this procedure two more times.
“Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or disposal.
