Effect of Fluensulfone on Meloidogyne incognita in onion crop.

Onion is a plant widely cultivated in the world, only behind potato and tomato. Mexico produces 1,487,102 t an area of ​​47,952 ha. In this study, nematode associated with onion cv. Cirrus was identified morphologically molecularly, effect fluensulfone (1.75, 2 2.25 L ha-1) fenamiphos (7 on population crop damage were evaluated. The species plants Meloidogyne incognita. preventive application decreased negative M. incognita yield, providing good control higher fenamiphos. At 60 days after sowing (das), Fluensulfone (2 reduced caused by 76-78 % 72-80 respectively compared untreated plants. 90 das, root galling less than 15 %. Plants treated (2.25 increased production commercial bulbs up to 14 Therefore, for management recommended, as part integrated plan root-knot nematodes.
