Four Solanum rootstocks were evaluated for resistance to RKNs in a naturally infested field, in two consecutive trials (dry season of 2015 and rainy season of 2016).
macrocarpon s chlorophyll content was also significantly increased (P [less than or equal to] 0.05), compared with the other rootstocks screened against RKNs (Figure 1(c2)).
bacteriophora (123.7), while the maximum number of J2s were recorded in control treatment (159.7) where only RKNs were applied.
EPNs is also being used as biological control agents against RKN infesting different crops in the field and green house (Shapiro-Ilan et al., 2006; Molina et al., 2007; Javed et al, 2012).
Determination of Reductions of Kernel Number (RKN) and Thousand Kernel Weight (RTKW)
The reduction of kernel number was defined by RKN = max[0;100 x (KNthreshold - KN)/KNthreshold].
Keeping in view the importance of the biological control, it was planned to investigate the biological control of RKNs through entomopathogenic bacteria.
and their associated toxins with bio- products i.e., abamectin, emamectin and azadirechtin tested against RKNs shows that combine effect of Abamectin and Xenorhabdous spp.
Amendments from a number of plants, including the castor oil plant (Ricinus communis), velvet bean (Mucuna spp.), marigold (Tagetes spp.), and sunn hemp (Crotalaria juncea), neem cake, Rakshak gold (a neem-based product) and cruciferous plants have been used successfully against RKNs (Randhawa et al., 2002; Wang et al., 2002; Hooks et al., 2010).
Previously, in vitro and in planta nematicidal activity of Fumaria parviflora Lam (Fumariaceae) extracts was evaluated against the southern RKN, M.
Both the EPNs when applied at 1250 and 2500/pot 24 h before or at the same time significantly (P less than 0.05) reduced the invasion of RKNs in tomato root.
The bacteria inside the root tissue release allelochemicals those are toxic and repellent to RKNs (Grewal et al., 1999; Fallon et al., 2002).
