Best Management and Application Practices

Comparison of Telone® C-17 Soil Fungicide and Nematicide
and Contact Nematicide
Telone® C-17 soil fungicide and nematicide Contact nematicide
Superb efficacy against Granville wilt  Ineffective against bacterial diseases
Effective management of black shank  Poor management of fungal diseases
Effective against all economically damaging nematode species  Not effective against all economically damaging nematode species
Reduces current populations of nematodes 

Varying degrees of control

Doesn't actually kill nematodes
Injected into soil where nematodes live  Relies on soil incorporation and water for direct contact
Creates a healthy root zone that promotes quality growth  Limited zone of control
Healthier roots for better fertilizer and water uptake  Roots more vulnerable to nematode damage, causing less efficient water uptake
Large window of application, November through April, for convenience and best fumigation conditions 

At-plant application and incorporation only

More vulnerable to cool, wet or dry weather conditions

 

 

 

 

 

 

 

 

 




 

 

Application Guides
Fumigation with Telone® soil fumigant products may be accomplished by using pumps variously driven by the ground, power take-off or electricity.

Application Instructions
Immediately after application, soil must be sealed to prevent fumigant loss and ensure effective concentration of fumigant is maintained.

Broadcast Treatment: Follow the applicator rig with a disk or field cultivator to seal in Telone C-17. This will slow product dissipation from soil and enhance performance.

Row Treatment: Form beds at application so fumigant is placed at least 12 inches from nearest soil/air interface. Preformed beds should be sealed by disrupting the chisel trace or by reforming beds.

Waiting Period
Soil temperature, soil moisture and application rate will determine how long the waiting period needs to be, regardless of which fumigant is used.

A waiting period is recommended for two reasons:

- A waiting period allows the fumigant more time to control soil pests in the soil profile.
- A waiting period allows the fumigant to dissipate before the crop is planted so crop injury is avoided.
 

Rates
Telone C-17 can be applied as a row or broadcast treatment.  Row treatment rates are from 7 to 10.5 gallons per acre. Broadcast rates are from 12 to 16 gallons per acre. The length of rotation and the history of disease and nematode pressure determine whether to use the low or high end of the rate range. If tobacco cyst nematode is present, use the higher rates. If you have questions, contact your Dow AgroSciences Telone Specialist.

Application Timing

Temperature: Soil at depth of application must be between 40 F and 80 F.
Soil Moisture: For fumigation depths greater than 18 inches, the soil should be moist within a 16-inch radius upwards from the point of injection. For all other applications, the soil must be moist from 2 inches below the soil surface to at least 12 inches deep. The amount of moisture needed in this zone will vary according to soil type.
Soil Preparation: Soil should be free of clods. Thoroughly incorporate plant residues. Fracture any compacted soil layers within treatment zone before or during application.
Application: Place at least 12 inches below the final soil surface as either a broadcast or row treatment.
Fumigation Interval: Leave the soil undisturbed and unplanted for at least seven days after application and then allow an additional day of aeration time per gallon used. (Example: 10 gallon rate = 1 week plus 10 days per 10 gallons = 17 total days). Check soil to see if odor of Telone C-17 is detected before planting.
Planting: Allow Telone C-17 to completely dissipate before planting.


 

 

 

 

 

 

 

 


Safety and Handling
Prior to working with Telone® C-17 soil fumigant, workers participate in a training program regarding safety procedures and handling of the product. Review the Storage and Handling Guide.

Label
Telone C-17 is a true multipurpose fumigant that is superior on nematodes and provides the best foundation for disease management. After Telone C-17 is injected into the soil, it converts to a gas and creates a zone of protection for the tobacco plant's developing roots.
