There are multiple tactics for managing SCN:

• Nematicides
• Rotation to non-hosts
• Resistant varieties
• Sanitation

Soil testing tips:

• Where in the field? Sandy to silt loam areas
• When? Fall is the best time, Spring is the worst time
• How often? Once per year
• Where should soil test samples be sent?

What to know about rotating different resistant varieties:

• There are several races of SCN.
• Problems will occur with SCN if varieties with the same type of race resistance are used continuously.

What to know about rotating different sources of resistance:

• There are a few soybean varieties with resistance to Southern root-knot and/or reniform.
• There are many varieties with resistance to SCN used in Louisiana.

What to know about rotating to non-host crops:

• Rotation will reduce damage caused by nematodes (but not in all cases).
• Corn may not reduce Southern root-knot populations.
• Rice and peanut are the best options for Southern root-knot and reniform.
• Sugarcane, corn, and grain sorghum are effective against reniform.
• Sweet potato is a major host of Southern root-knot and reniform.
• Wheat does not impact Southern root knot.

Nematode-protectant seed treatments:

• There are a number of seed treatment nematicides available to use on soybeans including Avicta Complete Bean, Poncho Votivo, and ILeVO.
•  The fumigant Telone II can also be applied but should be used in a site-specific manner.
