Tylenchulus Semipenetrans

Sixteen genera of plant parasitic nematodes were found in 64 soil samples taken around fruit trees of 20 different genera at Kununurra, Darwin, or Adelaide River. Hemicriconemoides cocophilus, Basirolaimus seinhorsti, Rotylenchulus reniformis, Helicotylenchus s p p., and Xiphinema s p p. were found in more than 25% of samples, and Meloidogyne spp.in 16%. Paratrichodorus minor and Rotylenchus incultus were common at Kununurra. Nematodes found in plant roots at Darwin included M. javanica and R. reniformis on Carica papaya, Radopholus similis on Musa sp., Scutellonema brachyurum on Spondias cytherea. Tylenchulus semipenetrans was found in Citrus sp. roots at Adelaide River. Helicotylenchus dihystera was found in roots of Annona spp. at both these places.

Citrus orchards in the Cobram district of northern Victoria were surveyed in 1976 for the presence of plant parasitic nematodes; in particular for the citrus nematode Tylenchulus semipenetrans. One hundred and forty-six soil samples were collected from 38 orchards. Nine genera were recorded, the most prevalant being Tylenchulus and Paratrichodorus (95 per cent and 37 per cent respectively, of all samples). T. semipenetrans was present in all orchards sampled. Population levels of T. semipenetrans larvae exceeded 1000 per 500 g of soil in 60 per cent of samples.

Vineyards in all five of South Australia's grapegrowing districts were surveyed for plant parasitic nematodes. Root-knot nematodes (Meloidogyne spp.) occurrcd in four districts, and were present in almost all vineyards with sandy soil in the Riverland, Barossa Valley and Central districts. Four species (M. arenaria, M. hapla, M. incognita and M. javanica) were identified. Citrus nematode (Tylenchulus semipenetrans) was wide-spread in Riverland vineyards, and isolated infestations were found in other districts. Other plant parasitic nematode genera found during the survey were Helicotylenchus, Macroposthonia, Paratrichodorus, Paratylenchus, Prat ylenchus, Tylenchorh ynchus and Xiphinema.

In a field experiment, the nematode-trapping fungus Dactylaria brochopaga and the nematode egg parasitic fungus Verticilium chlamydosporium , was evaluated against the citrus nematode, Tylenchulus semipenetrans infesting Mandarin, Citrus reticulata, , the mixed compound was applied in October 2016 at the rate ½ kg/tree, and root and soil samples were collected monthly until the next October, 2017. Successive treatment of the same mixed compound was added in the end of April 2017. For the comparison, Vydate 24% L. was applied as well as non treated check trees were left. Data revealed that the mixed compound treatment greatly affected the citrus nematode numbers both in soil and roots, in comparing with those of Vydate or induced by mixed compound was 97% and 70%; respectively in soil and roots. Rates of reproduction increase of the citrus nematode also reached 3% and 30% in both soil and roots; respectively. Vydate treatment resulted in a relatively lesser percentages. Growth of the concomitant fungus, Trichoderma sp. was increased specially in the last samples of October 2017, however those of fungi; Aspergillus flavus, Fusarium sp. And Rhizopus sp. was reduced, due to mixed compound treatment. Aspergillus niger and Penicillium sp. were not affected by the presence of the mixed compound. Vydate did not affect the co inhabitant fungi to a great extent.
