Stem and bulb nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936, is a plant parasitic nematode that causes significant losses in production the world. One of promising methods for control soil-borne diseases pests do not accumulate nature green manure application. Studies on effectiveness stem are limited. In this study, activity 4 species from Brassicaceae family one Tagetes patula L. ...

Disease complexes initiated by plantparasitic nematodes and bacteria on aerial plant parts are relatively uncommon. Interactions involving Aphelenchoides ritzemabosi (Schwartz) Steiner & Buhrer, Anguina tritici (Steinbuch) Chitwood, and Ditylenchus dipsaci (Kiihn) Filipjev with species of Corynebacterium are known (1, 3, 8). Ditylenchus dipsaci also is reported to interact with Erwinia rhaponti...

Plant-parasitic nematodes (PPNs) destroy over 12% of global food crops every year, which equates to roughly 157 billion dollars (USD) lost annually. With a growing population and limited arable land, controlling PPN infestation is critical for production. Compounding the challenge maximizing crop yields are mounting restrictions on effective pesticides because lack nematode selectivity. Hence, ...
