- Abstract
The objective of this study was to evaluate the activity of Ecolife® and manganese phosphite in the control of Meloidogyne javanica in soybean cultivars susceptible and resistant to the nematode. Seedlings of the susceptible (BRSMT-Pintado) and resistant (MG/BR 46 Conquista) soybean cultivars with 15 days of emergence were treated with Ecolife® (1.5 ml/L) or manganese phosphite (20 ml/L) at three different times: seven or one day prior to inoculation or seven days after inoculation with 2,000 eggs/plant. Untreated inoculated plants and untreated non-inoculated plants were used as controls. The number of galls, number of eggs/g root and vegetative parameters were evaluated 60 days after inoculation. The experiment was conducted in a greenhouse over two different experimental periods. The results demonstrated that the commercial product Ecolife® reduced the number of eggs/g root, mainly in the susceptible cultivar treated seven and one day prior to inoculation. Manganese phosphite reduced the number of nematode eggs/g root when the resistant cultivar was treated seven days prior to inoculation, but only in Experiment 1. Neither of the two products enhanced plant development.
