Management of the root-knot nematode, Meloidogyne incognita, on artichoke (Cynara cardunculus) with soil solarization and low doses of nematicides.

摘要

The effects of a 7-week soil solarization period, alone or in combination with low rates of 1,3-D [1,3-dichloropropene] (50 litres/ha), dazomet (125 kg/ha) or methyl bromide (200 kg/ha), on the yield of artichoke (Cynara cardunculus cv. Romanesco) and weed growth were studied in a M. incognita (race 1)-infested field in Cerveteri, Rome, Italy, during 1999 and 2000, and compared with the effects of standard rates of 1,3-D (150 litre/ha), dazomet (500 kg/ha) and methyl bromide (600 kg/ha). All treatments effectively controlled the nematode. The nematode soil population densities were reduced by 92-100 and by 81-99% in the first and second crops, respectively, resulting in low root gall indices and significant increase in the marketable yield of artichoke. Complete control of weeds was observed only in plots treated with solarization or methyl bromide..
