Fungicide options for soybean rust control are expanding
|
From Agriculture Online and SSBR.com staff 11/16/04
The decision about if and when to spray for soybean rust in the United States will be determined by how quickly the disease travels and by weather conditions, according to the North Central Soybean Research Program's Plant Health Initiative. It notes, also, that you should consult with your crop adviser or local Extension office to stay informed of fungicide spray recommendations for your area.
The good news is that control options are available and the list of fungicides approved for managing soybean rust is growing, according to materials from CropLife America (CLA) distributed today.
"Soybean rust can be controlled through the use of fungicides. Working with our partners in agriculture and government, we have developed a good plan and some solid tools to minimize the damage from soybean rust," said Jay Vroom, president and CEO of CropLife America, in a release. CLA is a trade industry association for makers of crop protection products.
CLA notes that two fungicides, chlorothalonil and azoxystrobin, have full registration for soybean rust control, according to the EPA.
Chlorothalonil is the active ingredient found, for example, in Syngenta's Bravo and Sipcam Agro's Echo 720. Azoxystrobin is the active ingredient found in Syngenta's Quadris SC.
Another five fungicides have received Federal Insecticide and Rodenticide Act (FIFRA) Section 18 Emergency Exemptions in some soybean producing states with similar exemptions pending in other states. The fungicides are:
1. Tebuconazole - found, for example, in Bayer CropScience's Folicur F.
2. Myclobutanil - examples include Dow AgroSciences' Laredo EC and Laredo EW.
3. Propiconazole - examples include Syngenta's Tilt EC, Dow AgroSciences' PropiMax EC, and Makhteshim-Agan's Bumper EC.
4. Boscalid - which is found, for example, in combination with pyraclostrobin in BASF's Pristine.
5. Pyraclostrobin - found, for example, in BASF's Headline EC.
Two additional fungicides, trifloxystrobin and tetraconazole, are currently awaiting their first FIFRA Section 18 approvals, CLA says. Examples of products that contain trifloxystrobin are Stratego, Flint and Compass from Bayer CropScience. Tetraconazole is found in Sipcam Agro's Domark SL.
Some of these crop protection products must be used in combinations to control soybean rust, according to CLA.
In anticipation that the disease might eventually reach the United States, Vroom says CLA worked closely with American Soybean Association, EPA, and USDA officials to obtain approval of fungicide products under FIFRA Section 18 for use by growers as emergency crop protection tools.
