Soybean Rust

Your plants should look like this

Don't wait until they look like this.

Facts about Soybean Rust:

• Asian soybean rust is the more virulent form of soybean rust and has reduced soybean yields in Brazil as much as 80%.

• Ideal temperature for soybean rust growth is between 68 and 77 degrees.

• Moisture for 6 to 12 hours increase chance of rust growth.

• Soybeans are  most vulnerable during flowering stages, R-1 to R-6.  During this stage, there is a medium canopy.

• Rust infestation usually begins at lower canopy directly over the soil surface.

• Should put fungicides down within a week once rust has been detected within your area.

Controlling Soybean Rust:

Rust resistant or tolerant varieties of soybean would be the most effective mechanism of control; however, all current strains of soybean have been test and none have been found tolerant.  “Research is ongoing , but such varieties sill are five to ten years away, “ says Neal Bredenhoeft, American Soybean Association President.

Currently, Fungicides are the only treatments for containing rust by decreasing the number of spores.

Materials for Applying Fungicide:

• Researches state application of fungicide in growing regions will need to be as followed: (growers should wait 14 to 20 days between applications)

• Southern soybean growers will need 2 or 3 applications

• Midwest growers should need 1 or 2 application

• Its important to fully coat the plant for fungicide so proper spray rigs, nozzles, adjuvants, and trained operators are needed.

Nozzle choice:

• Large number of small to medium sized droplets from a nozzle that will spray into the canopy and reach lower leaves are recommended.

• Twin flat fan nozzles recommended
