Conteúdo: | The effect of aldicarb and fenamiphos on Tylenchulus semipenetrans population densities and on orage yield was investigatesd during a 3-year (1986-88) field trial in Italy. Rates and times of application of the two nematicides did not affect numbers of females of T. semipenetranson the roots but suppresd (p = 0.05) egg, male, and second-stage juvenile population densities from October 1986 to 1988. Yield of affected by any treatment during 1986-87. Yied was increased (p = 0.05) in 1988 by i) a single application of 20 kg a.i./ha aldicarb, ii) 10 kg a.i./ha fenamiphos, and iii) an application of 5 kg a.i. aldicarb/ha in spring, followed by two more applications of 2.5 kg/ha each in june and September. Fruit size was not affected by the nenaticide treatments. Concertrations of fenamiphos and its metabolites, in rind and pulp, were below 0.02 ppm.
