We recommend annual soil testing. Results and Recommendations Upon completion of the analysis, a report with the plant nutrient levels and fertilizer and lime recommendations will be returned to you by mail. Recommendations will be made for the type of grass listed on the Record Sheet and will include comments on cultural practices or other specific recommendations. If you have any questions regarding the results or recommendations, your county Extension agent can help you. They can cause substantial damage to turf plants by feeding on the roots, thus hampering or even destroying the plant s ability to absorb nutrients and water.
Nematodes can also transmit or increase the susceptibility of most plants to diseases and viruses.
As a result of the root damage, plants show symptoms of reduced growth, nutrient deficiency symptoms such as yellowing, and excessive wilting in hot or dry weather. Ultimately these areas may become dead patches of grass. Damage often occurs in randomly spaced areas. The only way to positively identify the type and extent of a suspected nematode problem is by soil sampling and a laboratory assay. Lawns may be sampled any time when they are actively growing.
