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 کاملA Classification of Tylenchulus semipenetrans Biotypes.
The presence of two biotypes of the citrus nematode (Tylenchulus semipenetrans) in Italian citrus and olive orchards has been confirmed by comparing host specificity. Host reaction to California biotypes C1 and C3 and to three populations from Arizona, Texas, and Florida indicates that of these five United States biotypes, all except C3 consistently fit biotype C1. These findings, and the resul...
متن کاملEfficient Procedure for Extracting Tylenchulus semipenetrans from Citrus Roots.
Investigations were undertaken to determine the suitability of sucrose and magnesium sulphate solutions and a silica colloidal suspension with centrifugation for extracting Tylenchulus semipenetrans from citrus roots. The efficiency of incubation, sodium hypochlorite, centrifugation, and maceration methods was also compared. Numbers of females recovered by centrifugation with colloidal silica w...
متن کاملUse of Chitin for Controlling Heterodera avenae and Tylenchulus semipenetrans.
The nematicidal effect of chitin, relative to other pesticides, was evaluated against two plant-parasitic nematodes, Heterodera avenae and Tylenchulus semipenetrans. Wheat seedlings, grown in soils artificially or naturally infested with H. avenae, were treated with 0.4% (w/w) ClandoSan (CLA) prepared from crustacean chitin, aldicarb (Temik 15G), or ethylene dibromide (EDB 90EC). The CLA treatm...
متن کاملCharacterization of Citrus Rootstock Responses to Tylenchulus semipenetrans (Cobb).
Citrus rootstocks which significantly limited the reproduction of Tylenchulus semipenetrans (Cobb) "Citrus" and "Poncirus" biotypes responded to infection by producing a hypersensitive-type response in the root hypodermis, wound periderm and/or cavities in the root cortex, and/or abnormal vacuoles in nurse cell cytoplasm. Rootstocks which limited nematode reproduction also had significantly few...
