How to tell if you have Nematodes

Sometimes it is very difficult to tell from the turf surface if you have a drastic problem, but nematodes could be feeding away at your roots. But some basic signs are; yellowing of the turf, wilting, bare patches (that are not created from other pest), or weeds such as spurge are over taking the area.

Damage is especially noticeable in sandy soils with hot temperatures where water is not readily available in the top few inches of the soil profile. In the north, symptoms are more subtle.

A sure fired way to tell if you have a significant nematode problem is to have an assay done of your soil. Most county extensions and universities can perform such a test for a small fee.

How to treat for Nematodes

Nematicides are available for some applications, but not for Homeowners and most Sports Fields. And nematicides generally are very toxic, can harm the environment, and rarely treat problems associated with nematode damage. An application of DRAGONFIRE-CPP™ & RUTOPIA™ (Which is non-toxic, organic based and environmentally safe.) will suppress the nematodes, replace much needed nutrients and correct poor water retention in the soil.
