Management of the Citrus Nematode, Tylenchulus semipenetrans.
Of the many nematode species that parasitize citrus, Tylenchulus semipenetrans is the most important on a worldwide basis. Management of the citrus nematode remains problematic as no one tactic gives adequate control of the nematode. An overall management strategy must include such components as site selection, use of non-infected nursery stock, use of at lease one post-plant nematode control t...
متن کاملBio-management of root knot nematode and root rot disease by antagonistic fungi and rhizobacteria
Effects of four fungi and six rhizobacteria isolates from the rhizosphere of vegetable crops was studied for suppression of root knot nematode, Meloidogyne incognita and wilt fungus, Fusarium oxysporum f. sp. lycopersici on tomato in laboratory and pot culture experiment. All the isolates were isolated by serial dilution and cultured in liquid protein supplemented broth medium and culture filtr...
متن کاملPopulation Changes of Tylenchulus semipenetrans Under Localized Versus Uniform Drought in the Citrus Root Zone.
Population development of Tylenchulus semipenetrans in dry soil was investigated in a greenhouse study. Citrus seedlings were grown in sandy soil in vertical tubes with upper and lower sections. Nematode population densities in the upper tubes were measured at 16, 23, and 37 days, post-treatment. Three treatments consisted of i) irrigating both tubes when soil water potential reached -1 5 kPa (...
متن کاملEffects of oxamyl on the citrus nematode, Tylenchulus semipenetrans, and on infection of sweet orange.
Foliar sprays of 4 microg/ml oxamyl on sweet orange trees in a greenhouse slightly depressed the number of Tylenchulus semipenetrans larvae obtained from roots and soil, but similar treatments were not effective in two orchards. Soil drench treatments decreased the number of citrus nematode larvae obtained from roots or soil of citrus plants grown itt a greenhouse and in orchards. Exposure to 5...
متن کاملControl of citrus nematode Tylenchulus semipenetrans on fine-textured soil with DBCP and oxamyl.
Three grapefruit orchards on sour orange rootstock were treated by metering DBCP (l,2-dibromo-3-chloropropane) at 56 kg(a.i.)/ha into 15 cm of water in a flood irrigation system. In orchards with 43-49% clay in the surface foot, DBCP reduced numbers of Tylenchulus semipenetrans below control levels for 1.5-2.0 years. In the 3 orchards, DBCP treatment resulted in increases in yield or fruit size...
