Abstract

A pot experiment was carried out in order to evaluate the efficacy of four pre-planting herbicides i.e. Amex 48%, Atrazine, Nitrofen and Stomp 5% in comparison with Oxamyl on Meloidogyne incognita infecting okra plant cv Hyper Doki 1 under greenhouse conditions (25±5 ºC). It was evident that all tested pesticides improved plant growth parameters and reduced nematode with various grades. Atrazien overwhelmed other treatments in improving plant growth parameters for plant length (19.84%), whole plant fresh weight (29.32%) and shoot dry weight (66.03%), respectively, followed by Nitrofen for the same plant criteria with values of 15.53, 21.67 and 59.86%, respectively. Moreover, Oxamyl as a nematicide showed extensive values in improving plant growth criteria and ranked first in suppressing nematode population density in soil, galls and eggmass numbers. Atrazine accomplished the reasonable reduction percentage in nematode population density in soil followed by that of Amex 48% application with value of 25.27%. There was no significant differences between the values of RGI and EI indices which achieved equal values with those of nematode alone(4).
