Marigold Nematode Control Mix is effective for control of root knot and other plant-parasitic nematodes in the home garden. In India, marigolds have been used for this purpose for hundreds of years.
These charming, bright and easy growing flowers bloom all summer long while working hard just underneath the soil improving the fertility and reducing destructive inhabitants.
Marigold roots release the chemical alpha-terthienyl, one of the strongest naturally occurring compounds and is nematocidal, insecticidal and antiviral.
This naturally released chemical inhibits the hatching of nematode eggs. This process is called allelopathy - the ability of an organism to produce chemicals that are toxic to other organisms.
The most effective treatment is planting marigolds as a cover crop prior to planting the garden. Interplanting or companion planting can work with lighter nematode pressures.
