Nematodes, especially Meloidogyne sp., are hard to control due their aggressiveness and the lack of products registered for this purpose. Therefore, the objective of this work was to evaluate the in vitro nematicide / nematostatic potential of 1%, 5% and 10% of aqueous extract of Rosmarinus officinalis (rosemary) against M. incognita. The experiment was conducted in the Nematology Laboratory of Unioeste, Marechal Cândido Rondon, Paraná State. The experimental design was completely randomized, with four treatments, using three concentrations of aqueous extract of rosemary and water as control treatment, with five replicates each. Motility and mortality of second stage juveniles (J2) were evaluated after 24 and 48 h, respectively. The rosemary extract showed...

Manejo alternativo de nematoides de galha (Meloidogyne incognita) em feijoeiro (Phaseolus vulgaris) Sci. Agrar.Paran. / SAP
Borges, Fernando Gonçalves; Batisttus, André Gustavo; Muller, Mônica Anghinoni; Mioranza, Thaísa Muriel; Kuhn, Odair José.
The bean diseases have been responsible for major yield losses. The root-knot caused by the nematode Meloidogyne have been highlighted in recent years, especially in the soybean growing regions. Thus the aim of this study was to evaluate the potential of induction of resistance by Trichoderma and plant extracts compared with chemical terbufos and water in controlling nematode galls. Thousand nematode larvae J2 were inoculated in the root system of each plant. The evaluation took place 60 days after inoculation. The use of terbufos was efficient, but with the entire load of environmental impact. Alternative treatments of applying Trichoderma to the soil and incorporation of crotalaria leaves in the ground exerted the greatest effect in reducing the severity...
