Abstract

AbstractSoil-borne diseases is a widespread problem in protected cultivation in Sicilyespecially after the prohibition of methyl bromide use. Secondary metabolites of someBrassica species are biofumigant able to contrast the main soil-borne agents in view toestablish health and environmental friendly farming. In order to assess the effectivenessin nematodes control (Meloidogyne spp.) on tomatoes was carried out, adoptingfactorial design, a field trial in an representative farm of protected cultivation(Ragusa) using the flour of dry plants of Brassica juncea, Eruca sativa, Raphanussativus and Brassica macrocarpa. The first three species were previously studied bysome Authors as biofumigant, while B. macrocarpa is an endemic Sicilian wild speciesappearing interesting since recent scientific evidence showed high glucosinolatecontent in leaves, 90% represented by sinigrin, and the effectiveness of its dry leavesinserted into the soil to control root-knot nematodes in tomato crops, such as Meloidogynespp. Tritated flour for the sinigrin content was distributed before planting (60and 90 g m-2), the mean dose corresponded to the active molecules contained in thecommercial formulate (Nemathorin) applied as 3 g m-2 following the instructions.Disease index detected on the tomato roots at the end of the growing cycle (Lambertiscore, 1971), although low in general, resulted in all thesis lower than the control (1.2)and the commercial formulated (0.20), whereas it was between 0 (E. sativa 60 g m-2and R. sativus 90 g m-2) and 0.13 (B. juncea 90 g m-2).
