Mode of Action
Clariva pn contains the Pasteuria nishizawae bacteria as its active ingredient. When seed treated with Clariva pn is planted, the P.nishizawae spores are released into the soil and form a protective halo around the young soybean plant’s roots.
The P.nishizawae spores infect and eventually kill SCN by curbing their ability to feed and reproduce.
As the remnants of the infected nematodes decompose, the spores are then released back into the soil to provide season-long activity and protection.
Pasteuria nishizawae Pn1, is a naturally occurring soil microorganism. As part of use of this product we are recommending sound SCN management practice that also includes non-host crop rotation, rotate SCN resistant varieties, and rotate sources of resistance in SCN resistant varieties.
