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 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 کاملComparison of Peel Components of Mandarin, Sour lemon and Sour orange (Citrus sp.)

All compoundswere analyzed using GC-FID and GC-MS. Twenty-seven, Twenty-four and Twenty-nine peelcomponents were identified in Mandarin, Sour lemon and Sour orange respectively. They includealdehydes, alcohols, esters, monoterpenes an...
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...
متن کاملParasitism of the Citrus Nematode, Tylenchulus semipenetrans, by Pasteuria penetrans in Iraq.
Pasteuria penetrans Sayre & Starr parasitizes several nematode species and is considered a promising biocontrol agent of the root-knot nematode, Meloidogyne spp. (1,7). Numerous plant-parasitic nematodes, including Tylenchulus semipenetrans, however, are seldom if ever infected by this biocontrol agent (3). Tylenchulus semipenetrans Cobb is the most economically important and widespread nematod...
