BARROS, Andrea C. B.; MOURA, Romero M. e PEDROSA, Elvira M. R.. Studies on the effect of simultaneous application of herbicide and systemic nematicide on nematicide efficacy in sugarcane fields. Fitopatol. bras. [online]. 2006, vol.31, n.3, pp.291-296. ISSN 0100-4158. http://dx.doi.org/10.1590/S0100-41582006000300008.
The effect of interaction between herbicides (diuron, ametrina, oxyfluorfen, and pendimetalin) and systemic nematicides (aldicarb and terbufos) on growth and yield of sugarcane (hybrid ofSaccharumspp.) variety SP79-1011 in soil naturally infested with Meloidogyne incognita, M. javanica andPratylenchus zeaewas evaluated in two different experiments: irrigated and not irrigated, in Northeastern Brazil. Evaluations were based upon nematode population densities and reproduction factor, plant growth, crop productivity and two technological parameters. There was no interaction between herbicides and nematicides in the sense of reducing nematicide efficiency, except in an irrigated experiment for number of stalks in herbicide treatments and number of stems and stalks in nematicide treatments. Nematicides and herbicides did not affect Pol and PCC levels at harvesting. There was interaction between nematicide and herbicide forP. zeaein the rhyzosphere in the irrigated experiment, with the lowest population found in aldicarb + pendimetalin interaction.
