Control of food legume nematodes in the Mediterranean Basin1

Control of food legume nematodes should consider the nematode species, type of crops, whether for grain or fresh pod production, environmental conditions and the economics of the crops. In general, 3–4âyear crop rotations could provide sufficient control of Heterodera goettingiana and H. ciceri and to a lesser extent also of Meloidogyne artiellia. Soil solarization has shown promise in controlling Pratylenchus thornei and H. ciceri on chickpea and has also been reported to be effective against Meloidogyne spp. The use of fumigants such as 1,3âdichloropropene or 1,3âdichloropropene + methylisothiocyanate and also of nonâvolatile nematicides (aldicarb, oxamyl, carbofuran, thionazin and fenamiphos) gives good control of these nematodes resulting in impressive yield increases in heavily infested soil. However, both nematicides and soil solarization are expensive and their use may not be economic in most cases. The use of resistant cultivars is, so far, of little importance due to very limited number of those with good agronomic characteristics. To ensure good yield of faba bean, attention must also be paid to producing seed stocks free from Ditylenchus dipsaci. In addition, quarantine regulations must avoid spread of this nematode among different countries.
