Abstract

A pot experiment was conducted to assess the efficacy of sixcommercial nematicides with ten formulations namely ethoprophos (Todabeet®, Root Phos®, and Nemafeng®), fenamiphos (Javelin®), fosthiazate (Capsul pro®),cadusafos (Rugby®), oxamyl (Mass Tode®, Oxyle®, and Canzakel®), and bionematicide abamectin (Namazoho®) against Meloidogyne incognita on sugar beet plants based on numbers of galls and juveniles (J2s) as well as plant growth characteristics. The nematicides were applied to the soil at the recommended dosage rate. All nematicides caused a significant reduction in the number of J2s and root galls with different levels of efficacy. However, ethoprophos (Todabeet ®) and ethoprophos (Root Phos®) had the highest nematicidal effect with a 100 % reduction in the number of juveniles in soil and galls, while oxamyl  (Mass Tode®) and cadusafos (Rugby®) were relatively least effective causing 63.2 and 65.91 %; 64.6  and 69.5 %; reduction in J2s population and galling, respectively. Abamectin (Namazoho®), fenamiphos (Javelin®), ethoprophos (Nemafeng®),oxamyl (Oxyle®), oxamyl (Canzakel®), and fosthiazate (Capsul pro®) ranked intermediate in descending order by 89.4 and 87.5%; 88.3 and 89.77 %;  87.2  and 95.45 %; 84.4  and 87.5 %; 70.1  and 63.64 %; 68.9 and 59.09 %  reduction in J2s population and galling, respectively. Also, all of the nematicides significantly increased plant length, fresh weight, and shoot dry weight. Ethoprophos (Root Phos®) had the highest increase effect. However, all nematicides significantly decreased N, P, K, and total chlorophyll content compared to the control, while abamectin had the highest decrease effect.
