Figures & Tables

A – B: Root systems of infected Swiss chard plants showing root galls and egg masses of M. javanica. C: Galled roots with stained egg masses of infected Swiss chard as viewed under a stereomicroscope. egm=egg mass; g=galls.

RKN infected Swiss chards showing pale coloured leaves.

Table 1.

Effect of Ag-NP on the number of egg mass, juveniles, and reproduction of Meloidogyne javanica on Swiss chard.

Treatments (Ag-NP)	Egg masses /root system	Juveniles/root system	Reproduction factor RF (pf/pi)
Control	254.14^a	29946.14^a	9.98^a
1 μg/mL	244.43^ab	28021.71^a	9.34^a
2 μg/mL	130.86^ab	13661.71^ab	4.55^ab
3 μg/mL	115.14^b	2909.71^b	0.92^b

* The mean is significant at the 0.05 level.

Table 2.

Pearson correlations between variables of M. javanica reproduction and Ag-NP treatments.

Variables	Treatments	Egg masses/root system	Juveniles/root system	Reproduction factor (RF)
Treatments	1
Egg masses/root system	−.482^**	1
Juveniles/root system	−.604^**	.781^**	1
Reproduction factor	−.606^**	.780^**	1.000^**	1

** Correlation is significant at the 0.01 level (2-tailed).
