They include nematicides, crop rotation, and resistant varieties. If the plants are given adequate time to form a normal root system, yields can be significantly improved. Even though some nematicides control SCN chemical treatments are generally not cost effective for soybean fields. Soybean Cyst Nematode levels in southern Indiana counties with fewer than 10 samples. After the chemical ceases to be active in the root zone, surviving nematodes will begin to feed and reproduce on the roots so that subsequent population levels can become high.
Rotation can be with non-host crops such as corn, sorghum, milo, wheat, rye and oats.
If any form of tillage occurred, the effectiveness of the control decreased. Currently, a study has been initiated at the Southwest Purdue Agricultural Center to evaluate different rotations or cover crops in no-till practices. Studies also have been established to evaluate nematode levels in the presence of common weeds associated with corn and soybean fields in southern Indiana. The use of resistant varieties in conjunction with crop rotation is desirable to enhance SCN control. When a field is infested with low to moderate levels of SCN, resistant varieties should be used to reduce SCN reproduction and increase yields.
