RUST FORECASTS
USDA SBR Forecast 7/5/2006: Rain along cold front, including over TX, LA and AL. Front to move to the Carolina coast, northern FL and the Gulf Coast by tonight, resulting in significant rainfall in the
Mid-Atlantic region, the Carolinas, southern GA, northern FL and the Gulf Coast region through Friday. Weak high-pressure system to stay over SE states with generally dry conditions over weekend, but SE flow from the Gulf to bring rain to S. Texas.
NAPDFC forecast 7/5/2006: Rust source in Lafayette, La., has been added to trajectory forecasts. Rains expected near the sources over Wed/Thur, especially in FL and LA, which will lead to some localized
disease development. Low risk to susceptible plants Wed-Thu. New forecast due out tomorrow (7/7/2006).
The National Hurricane Center says no tropical storm development expected through Friday.
See our SOYBEAN RUST TRACKING CENTER for updated forecasts.
NEW THIS WEEK
ALERTS: Soybean rust found in LA kudzu (6/30) and AL soybean sentinel plot(6/29)
Asian soybean rust was found June 30 in a small patch of kudzu south of Lafayette, La., in Lafayette Parish -- the 23rd positive county in the U.S. and fifth state to have rust this year. The day before, the second confirmation of soybean rust on soybeans this year was reported for leaves from a
sentinel plot at Fairhope, AL, in Baldwin County. While LA state officials did not tell growers to spray yet, GA officials did, based on the AL find. (See GA update below and full story links.)
Full LA rust story.
Full AL rust story.
Quick state updates:
Georgia: "Rust-like" spores confirmed from spore traps at two U of GA sentinel plots in S. Ga last week, per 7/5 state commentary. No rust yet on GA soybeans; rust persists on kudzu in Brooks, Miller
counties. State recommendations for fungicide sprays remain same as from time of detection in Baldwin County, AL, last week: "Soybean growers in SW GA should consider spraying crop as crop enters flowering growth stage to insure max. protection from rust. Growers elsewhere in GA should be prepared
to spray once rust is found advancing to their region in our sentinel plots and their crop has entered reproductive growth stages."
Delaware: Nineteen soybean fields are being checked weekly for soybean rust including the five sentinel plots, which were sampled for the first time this week. Septoria brown spot is present in all of the sentinel plot samples.
Missouri: Samples have been submitted from 23 of the 26 sentinel plots, all negative for soybean rust so far.

Latest USDA Soybean Rust Observation Map 7/6/2006.
Red counties are positive for rust at the moment, 19 in U.S. now with first LA find, in Lafayette Parish, on 6/30. Red-hatch counties are rust confirmed/destroyed=1. Total positive county count now 23.
Good of IL: Markets react to USDA reports, crop concerns
The USDA June Acreage and Grain Stocks reports provided a few surprises for the crop markets, on top of crop concerns from continued heat and dryness, says Univ. of Illinois economist Darrel Good in his Weekly Outlook.

Ohio soybeans may take hit from flooding injury
Some of Ohio's soybean fields are facing flooding injury due to heavy rains that have swept across the state over the past few weeks.
Full story.
Crop Progress: Eighteen percent of U.S. soybeans are blooming. Condition down slightly from week: 64 percent in excellent/good condition (down from 67); 27 percent fair; 9 percent poor/very poor.
Full story.
Dorrance says weather stalled soybean rust development
Anne Dorrance of Ohio State says their sentinel plot soybeans are approaching the first flowering stage, and "it’s very unlikely with these low levels of inoculum that our growers are going to have to deal with (soybean rust)," she said. Monitoring will continue.
