USDA notes that it was carried by wind from South America in 2004. It is now found in 16 US States, plus Gulf coast Mexico.
5
Spread Amount
Infects legumes, concurbits, kudzu and corn. Wind borne. Requires high humidity, which may help control spread in California interior.

Damage
Notes

Ecological
Potential impact to native legumes. Control of pest requires use of fungicides.
3
Agricultural
Significant pest of key soybean, bean, corn, and cucumber crops. Reduces yield 10-80% depending on infection level. Devastating if untreated. Affects Quality

Detection
Readily detectable by trained observers.
5
Control
Shortages of registered fungicides in CA will make control very difficult if introduced. Easily controlled with fungicides registered elsewhere.

Tools in Place
Notes
Score
Entry
Strong measures in effect in central U.S. and Gulf Coast. Weaker in West. Windborne spread; no way to prevent it from crossing boundaries and borders, but presently distant.
2
Control
Survey for early detection is essential. Limited potential for control if eradication effforts fail.
3
Outreach
Well developed outreach in other U.S. areas were developed following introduction and spread. Cloning these efforts would be effective here. National source BMPs, tools, FAQs available.
