Abstract

Mouhanna, A.M. 2018. Primary evaluation of Acibenzolar-S-Methyl (ASM) efficiency on vegetative parameters and resistance responses of tomato and eggplant to root-knot nematode Meloidogyne incognita.

Efficiency of Isolates of the Fungus, Paecilomyces lilacinus to Control Disease Root- Knot Nematode,Meloidogyne javanica on Eggplant

“…The reason may be due to the efficiency of this isolate in parasitism the eggs of nematodes, which led to a reduction in the galling index and number of galls on the root system, especially that this experiment was carried out at a temperature of 30 ± 5 °C, which is ideal for the growth of the fungus and its ability to infect the eggs of root knot nematodes, and this applies with previous studies [3,10,14]. It is also observed from (Table 2) that all isolates of P. lilacinus achieved a significant reduction in the average number of egg masses on the roots system compared with the control treatment after five weeks of adding the nematode inoculation.Fungi that parasitism of the eggs of root-knot nematodes play a major role in biological control, especially the types of nematodes that lay their eggs together in a gelatinous matrix as root-knot nematode [11,1,9]. This agrees with what [11] found that the fungus P.…”

“…Paecilomyces lilacinus is one of the most efficient types of fungi that invading both females and egg masses of the root-knot nematode Meloidogyne spp. [11,12,6]. Other studies showed a high efficiency of P. [13,14,5,7.…”
