...ext-align: justify;">The potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) (PTM) is the most destructive pest. One of the most successful groups of biological control agents against soil insect pests are the entomopathogenic nematodes (EPNs) in the families Steinernematidae and Heterorhabditidae. This study assessed the effects of EPNs (Nematoda: Steinernematidae) species [Steinernema feltiae (Balıkesir isolates) and Heterorhabdit...

This research was conducted to evaluate the effect of irrigation methods, cultivars, vermicompost (VC) and their interactions for management of the MI and RS disease complex under field conditions. The experiment was laid out in a split-split plot design with three replications. The findings indicated that the treatments and their interactions significantly (P ≤ 0.05) affected the development of MI, RS...
