Nematode- Shrubs
Nematodes are microscopic roundworms that may cause considerable harm to crops and live in the soil. Nematodes feed by sucking out the fluid stays of plant cells, inserting juices and piercing plant roots. Controlling nematodes is hard because there are so many different species and various methods by which a plant is attacked by each species. Some crops resist one kind of nematode but are extremely vulnerable to another. Azalea, by way of example, tolerates root-knot, but falls victim.
Root-Knot
Root-knot nematodes produce galls that are elongated . These galls usually range between 1/8 and 3/4 inches. and are obvious Infestations result in several galls on the roots of crops that are susceptible. As well as azalea, Japanese camellia (Camellia japonica), juniper cultivars including Blue Rug and Spiny Greek, as well as Nandina domestica (typical names nandina and heavenly bamboo), all provide tolerance to nematodes that that creates root-knot galls.
Stunt
Nematodes feed touring through the soil along rhizomes or root methods. When huge infestations of stunt nematodes attack concurrently damage happens. Japanese boxwood (Buxus microphylla), American boxwood (Buxus sempervirens), camellia (Camellia japonica), the Compacta cultivar of Japanese holly (Ilex crenata), plus juniper cultivars and nandina tolerate this kind of nematode.
Lesion
Roots which can be stunted in development are left behind by lesion nematodes and therefore are often mirrored in the root construction that is whole. Lesions on roots that are personal are an early indication of infestation. Common gardenia (Gardenia jasminoides), daisy gardenia (Gardenia radicans), the Compacta cultivar of Japanese holly (Ilex crenata) and nandina resist lesions caused by nematodes.
Ring
Damage is extremely comparable to root mass left left out by lesion nematodes and the places. Nandina, Gardenia radicans, Gardenia jasminoides, juniper and Azalea show resistance to ring nematode assaults.
Other Nematodes
Root- lesion, stunt, knot and ring are common kinds of nematodes, but a lot of others exist in damage plant roots and the soil. Dagger nematodes depart swollen root ideas with galls that appear similar to all those -knot. Azalea in certain is very vulnerable to dagger nematodes. Stubby root nematode sting darken and rot root masses, and leaves a root mass that is wilted. The nematode that is latter impacts camellia and juniper. County extension offices and Nurseries might be in a position to help determine the specific nematode species attacking a backyard.
