On-farm Trial Results Demonstrate Effectiveness of Site-specific Technology

On-farm trials comparing yield in site-specific zones infested with root-knot nematodes show that areas treated with Telone® II soil fumigant consistently produce superior results over untreated soils.

In the above trial conducted in Missouri, with a shallow EC range of 0 to 16.5, land treated with Telone II in site-specific areas produced higher cotton lint yields by an average of 358.5 pounds per acre. One plot, with a high EC level, yielded 1,464 pounds per acre. Overall, areas treated with Telone II outproduced untreated land throughout the field. Even though the difference appeared to be more pronounced in the site-specific zones, the entire field would have likely benefited from the application of Telone.

Similar results were found in Arkansas based on the EC levels in soil with a shallow EC range of 0 to 19.8. Based on the outcome of the trial, the application of Telone II at 3 gallons per acre yielded a return on investment of $119 per acre in low EC soils and $63 per acre in high EC soils. These calculations are based on $40 per acre application costs and assuming 50-cent-per-pound cotton.

On the same farm in Arkansas, the efficacy of Telone II was measured when it was applied in low EC zones using site-specific application in fields that were ripped and unripped. In this trial, both ripped and unripped fields produced higher yields when Telone II was applied through site-specific application.

Three different plots were tested in the trial above. In one plot,   Telone II was applied across every acre at 3 gallons per acre. Another plot went untreated. In the final plot, Telone II was applied at 3 gallons per acre on 63.6 percent of the acres using site-specific application, reducing the application of Telone II by 37 percent. The plot treated with Telone II using site-specific application yielded best with an average of 1,445 pounds per acre.
