I discovered I had RKN a few years ago. I thought they were confined to a couple of beds in one garden area. Have now discovered that they are everywehre and infesting everything. Even tho they are not native to my area. I have been mineral balancing and make large amounts of hot compost. I am at my wits end.
Bacillus firmus and Paecilomyces lilaacinus are being used as inoculants in India against RKN but I cannot find any US suppliers. Wondering where I could find them / grow them. Hoping Dr. @RedHawk will see this and give his input!
PS;I know about covercropping marigolds and mustard and solarizing. Just hoping for a different approach that doesn't take the space out of production as I don't have much room.
hau Mary, RKnematodes can be controlled by introducing arbuscular mycorrhizae to your plant roots. the arbuscular mycorrhizae will capture and devour the RKN.
In case you want to know, I like the Fungi Perfecti Myco Grow, one packet will make 10-12 gallons of mycorrhizal soak (I use a tea spoon per gallon of water and add 1 tablespoon of molasses or honey and let it sit for two days before using).
To install just poke some holes from half way from trunk and drip line then water with the solution, you want to get all the way down to the root zone (18" deep).
For vegetables you can purchase the specific packet or simply use the maroon colored one (the only one I buy).
Here's what you get in the maroon colored one ounce packet (around 8 dollars):
