“…Most field trials on biological control of nematodes using trapping-fungi as a manageable tool utilize spores as potential structures to vehicular them into soil (Giuma & Cooke, 1974;Sahebani & Hadavi, 2008;Noweer & Al-Shalaby, 2014) and keep longer their permanency in it. In this study, Hohenbuehelia species did not present spores formation in asexual state (Nematoctonus).…”

Biological control is a method of controlling pests through the use of other living organisms. The purposes of this study were to test Hohenbuehelia species as biological control agents against Panagrellus redivivus in vitro, evaluating nematodes influence on mycelia growth; establishing daily indexes for predation and growth and setting predation percentage. Five species previously identified as 436-Hohenbuehelia mastrucata (Nematoctonus hamatus), 528-H. bullulifera (not described so far), 581-H. paraguayensis (N. sp.), 582-H. sp. (N. sp.) and 631-H. portegna (N. campylosporus) were submitted to anamorphic purification directly from basidioma. Afterwards, 100 nematodes were added to each pure colony for predation test. Evaluation started right after 24 hours of nematode-fungus interaction. Immobilized and/or penetrated nematodes were counted and mycelia growth was measured. Results were subjected to variance analyses. Hohenbuehelia mastrucata had the best performance in growth speed, followed by H. portegna and H. paraguayensis; Nematodes multiplyied much but none specie grew more as an influence of their movement under mycelium, however all species formed trap devices and some of them produced adhesive or repelent substances. Trap devices were formed in control plates also. The plates of H. paraguayensis without nematodes grew more than treatments. Cumulative predation of H. portegna was the highest at 24 (195.5%) and 48 hours (235%). At the last evaluation day, H. paraguayensis preyed the same amount (185.75%) than H. portegna, followed by H. mastrucata (109.51%). Resulst of predation daily indexes displayed chronological activity for each isolate, where H. portegna was very reactive at first 24 hours, H. mastrucata raised its predacious activity in 48 hours being constant from this time on and H. paraguayensis pointed out itself at 72 hours. Other species presented low predation and growth indexes throughout experiment.

“…Despite differences in fungal application method, our result is supported by other studies. Variation in M. javanica (Sahebani and Hadavi, 2008;Al-Hazmi and TariqJaveed, 2016) and Meloidogyne enterolobii Yang and Eisenback (Jindapunnapat et al, 2013) suppression because of different concentrations of T. harzianum Rifai were also reported.…”

A factorial experiment was established in a completely randomized design to verify the effect of different inoculum levels of an Iranian isolate of Trichoderma longibrachiatum separately and in combination with various concentrations of cadusafos against Meloidogyne javanica in the greenhouse. Zucchini seeds were soaked for 12 hr in five densities (0, 10 5 , 10 6 , 10 7 , and 10 8 spores/ml suspension) of the fungus prior to planting in pots containing four concentrations of cadusafos (0, 0.5, 1, and 2 mg a.i./kg soil). The data were analyzed using a custom response surface regression model and the response surface curve and contour plots were drawn. Reliability of the model was examined by comparing the result of new experimental treatments with the predicted results. The optimal levels of these two variables also were calculated. The interactive effects of concentrations of Trichoderma and cadusafos were insignificant for several responses such as the total number of eggs per gram soil, the number of intact eggs per gram soil, nematode reproduction factor, and control percent. Closeness of experimental mean values with the expected values proved the validity of the model. The optimal levels of the cadusafos concentration and Trichoderma concentration that caused the best plant growth and lowest nematode reproduction were 1.7 mg a.i./kg soil and 10 8 conidia/ml suspension, respectively.

“…Some soil borne fungi are difficult to eradicate because they produce resting structures like sclerotia, chlamydospores or oospores for their survival for a longer period of time under adverse environmental conditions (Baker and Cooke, 1974).Control of plant diseases by the use of antagonistic microorganisms can be an effective means (Cook and Baker, 1983). A large number of plant diseases have been successfully controlled through fungal and bacterial antagonists (Sahebani and Hadavi, 2008;Federico et al, 2007;Cook and Baker, 1983;Campbell, 1989;Vidhyasekaran et al, 1997). Trichoderma species have been used in the management of crop plant diseases.…”
