Soybean Cyst Nematode Sampling

October 9, 1998







Soybean cyst nematodes can reduce the value of the Illinois crop by more than $70 million yearly. However, producers can take a number of steps to reduce the impact of SCN on their soybean crop. This includes oil sampling, crop rotation, and the planting of resistant varieties.



Illinois and other Midwestern states are involved in a 3-year soil sampling and educational program to assist producers in reducing the damage done by SCN. This is a cooperative program funded by regional and state checkoff monies. The Illinois Soybean Board, Illinois Soil Testing Association (ISTA), and University of Illinois Extension are coordinating this statewide program. Soil samples are being processed by member labs of ISTA and the results sent to the U of I to be entered in a database. Labs that are members of both ISTA and the Illinois SCN Coalition are listed in this issue.



Results to date indicate that every soybean field is a potential SCN site. Of 1,106 samples processed, only 8% had no SCN. Distribution of SCN in the remaining samples (per 100 cc's of soil) was as follows: 1 to 3 cysts: 20.5%;4 to 10: 35.3%; 11 to 20: 22%; and 21 or more: 14.1%.



SCN management measures are recommended if the number of cysts exceeds 3 in 100 cc of soil. These results imply that at least 70 percent of the soybean fields in Illinois are above threshold. These samples were from 37 different counties, from Kankakee County in the north central area to Lawrence County in the south, and extending across the state.



Probability is high that SCN is present in most fields; in many cases, no above-ground symptoms are seen. So, a soil sample is an excellent first step toward reducing losses. Now is an excellent time to collect samples. The Illinois Soybean Board is providing from checkoff monies to help reduce the cost of soil sample processing. SCN Coalition labs will process samples at a reduced rate as a part of the educational program.
