Efficiency of some pesticides of control the disease root knot nematodes caused by Meloidogyne spp. on tomato plants
AbstractThis study was conducted to evaluate the effectiveness Abamctin, Garland, Resyst three concentrations of 1, 2and 4 ml L-1 in against nematode roots on the tomato. The results showed the effectiveness of each of them in reducing the percentage of the guide patients and the severity of the injury and significant differences for treatment comparison .as achieved treatment before the infection concentration of 4 ml L-1 highest percentage cut to guide patients reaching 1.33 for Abamectin and Alcarlnd compared the treatment of the comparison, which amounted to 4.66. While disease severity amounted to 20% of Abamectin and 26% for Carlnd while the treatment of 95% in comparison. The results showed that all treatments concentration of 4 ml L-1 positively to growth standards for plants tomato of weight mild and dry plants compared with the comparison treatment. Appearance results and there were significant differences for the numbers of adolescent superiority of the treatment before the infection concentration of 4 ml l-1 less number of second stage juveniles. As it recorded 10.33, 50.33, 73.33 young in comparison with the comparison, which reached the highest, number of J2 increased by 106.66.
