Dimethyl disulfide (DMDS), the natural biopesticide extracted from Allium spp., was evaluated against root-knot nematode (Meloidogyne incognita) of tomato (Lycopersicon esculentum L.) in greenhouse pot culture. All concentrations of DMDS viz. 30 ml, 60 ml, and 80 ml and Aldicarb @ 2g per square meter of soil were effective against root-knot disease under both wet and dry conditions of soil. Nematode incidence was reduced drastically by higher dose of DMDS and Aldicarb @ 2g but did not accelerate vegetative growth of tomato plant especially when tomato seedlings were transplanted immediately after soil treatment. Low concentration of DMDS (30 ml per square meter of soil) was found appropriate for controlling root-knot nematode of tomato, accelerating saprophytic nematode population in soil and also enhancing vegetative growth of tomato plant under dry condition of soil.   DOI: http://dx.doi.org/10.3329/bjar.v36i4.11759   Bangladesh J.

Biocontrol Potential

ABSTRACT One of the main pathological problems for cropping sacha inchi (Plukenetia volubilis L.) is its susceptibility to root-knot nematodes (Meloidogyne incognita). In this study, fungal endophytes were explored in the stems and leaves of seven species of the Plukenetia genus, and also evaluated the abilities of isolates of Trichoderma and Clonostachys as biocontrol agents against damages caused by this nematode in sacha inchi. In order to evaluate such effects, seedlings were colonized with these fungal isolates, and then they were infested with root-knot nematode eggs. The results showed that the Plukenetia genus is rich in diversity of fungal endophytes. Their greatest diversity was found in Plukenetia brachybotria. Among the most efficient isolates for endophytic colonization, some of Trichoderma (e.g., kmd-36 and kmd-54) and others of Clonostachys (e.g., kmd-68 and kmd-80) provided a significant (p < 0.05) reduction in the number of galls induced by the nematodes, in comparison to the control treatment without endophytic colonization. In addition, these isolates allowed a better root development in the tested plants, thus revealing a good biocontrol potential against M. incognita in sacha inchi.
