Management of the Citrus Nematode, Tylenchulus semipenetrans.

Journal of nematology, 2011
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

Screening culture filtrates of fungi for activity against Tylenchulus semipenetrans

Spanish Journal of Agricultural Research, 2009
Culture filtrates of 20 fungi isolated from citrus soils were screened for their activity against Tylenchulus semipenetrans in both in vitro and greenhouse tests. The filtrates of Talaromyces cyanescens (isolates 2-4 and 2-5), Paecilomyces lilacinus, Chaetomium robustum, Acremonium strictum, Engyodontium album, Myrothecium verrucaria, Emericella ...

Determination of Tylenchulus semipenetrans Biotype in Zebediela and Champagne, Republic of South Africa [PDF]

Plant Disease, 2008
The biotype of the citrus nematode (Tylenchulus semipenetrans) from Zebediela and Champagne Citrus Estates, Republic of South Africa, was determined using 2-year-old differential hosts, namely, grape (Vitis vinifera cv. Richter 110), carrizo citrange (Citrus sinensis × Poncirus trifoliata), rough lemon (C. jambhiri), olive (Olea europaea cv.

Sampling Citrus Fibrous Roots and Tylenchulus semipenetrans.

Journal of nematology, 2011
Sampling precision was investigated for Tylenchulus semipenetrans juveniles and males in soil and females from roots and for citrus fibrous root mass density. For the case of two composite samples of 15 cores each, counts of juvenile and male nematodes were estimated to be within 40% of mu, at P < 0.06 (alpha) in orchards where x > 1,500 nematodes/100 ...
