GOEHRING OKs REGISTRATIONS FOR SUGARBEET FUNGICIDES

BISMARCK – Agriculture Commissioner Doug Goehring has issued Section 24(c) Special Local Needs (SLN) registrations to United Phosphorus, Inc., shortening the pre-harvest interval (PHI) for two popular fungicides used to control Cercospora leaf spot on sugarbeets.

“These SLN registrations for Super Tin® 80WP and Super Tin 4L Fungicide will allow sugarbeet growers to better manage Cercospora leaf spot, especially when conditions favor disease outbreaks late in the growing season,” Goehring said. “Since a federally registered pesticide that effectively manages this pest with the desired PHI is not available, I believe these registrations are consistent with the intent of federal law because the situation meets the criteria of a special local need.”

The two registrations shorten the PHI from 21 to 7 days. The pre-harvest interval is the time that must elapse between the last application of a pesticide and the harvest of the treated crop.

Goehring said Cercospora leaf spot is the most serious disease affecting sugarbeets in North Dakota, and can cause losses of more than $35 million annually.

The registrations for both formulations allow ground or aerial application at a rate of 4 to 8 fluid ounces of active ingredient per acre, the same as the Section 3 labeling for the product.

Other SLN-registered products containing the same active ingredient (triphenyltin hydroxide) for use on sugarbeets in North Dakota with a PHI of 21-7 days include Super Tin 4L Fungicide, DuPont Super Tin 4L Fungicide and DuPont Super Tin 80WP Fungicide, all made by DuPont Crop Protection, and Agri Tin and Agri Tin Flowable, both manufactured by NuFarm Americas.

North Dakota is the second leading sugarbeet-producing state, growing 19 percent of the U.S. total.
