Management of Root-Knot Nematode (Meloidogyne incognita) on Bell Pepper (Capsicum annuum L.) under Green House Condition

Chilli (Capsicum annuum L.) crop is highly susceptible for the root knot nematode Meloidogyne incognita and every year this nematode causes great loss to the crop. The present study investigated the cumulative effect of two biocontrol agents viz. Pasteuria penetrans and Paecilomyces lilacinus against M. incognita. Two doses of P. penetrans i.e. 50g/Kg and 100g/Kg infested soil were applied either alone or in combination with two doses of P. lilacinus i.e. 4g spore culture/Kg and 6g spore culture/Kg of soil. Application of P. penetrans with P. lilacinus resulted into relatively better improvement in various growth attributes of chilli when compared with the individual application. Amongst the various treatments tested combined application with the higher dose of both bioagents (i.e. 100g P. penetrans infested soil with 6g of P. lilacinus/Kg) showed maximum improvement in fresh and dry weight of shoot and root over the nematode check and it was almost at par with that of the absolute check. The combined application of both the bioagents at higher dose resulted in 139 and 84% increase in dry weight of shoot and root over the nematode check respectively. The combined application of both the bioagents was also observed to cause higher reduction in gall number and nematode population than their individual application except for the treatment having lower dose of the P. penetrans with P. lilacinus where reduction in both the parameters was observed to be at par with that of the either dose of P. penetrans or higher dose of P. lilacinus. Combined application with higher dose of P. penetrans and P. lilacinus showed maximum reduction of 62.6 and 82.2% in gall numbers and nematode population over the nematode check.

Southern Root Knot Nematode

Newly bred resistant bell pepper varieties and those grafted onto resistant rootstock s were tested in soil severely infested with southern root-knot nematode [Meloidogy11e incognita (Kofoid and White) Chitwood] in unheated plastic house and compared to varieties on their own roots, in order to evaluate the efficiency of this environmentally friendly control method. 'Cinema F I ' carrying the N gene yielded significantly more than the two susceptible varieties. Varieties grafted onto resistant rootstocks outyielded those on their own roots although to different extent, which was not always significant. At the end of the vegetat ion period the roots of the rootstocks were undamaged and the roots of some resistant varieties were slightly infected. whereas the roots of susceptible varieties were severely damaged. According to our result . both the use of resistant varieties and grafted plants offer an effective and environmentally safe way of controlling M. incognita.

E-mail: [email protected] 1 RESUMO Neste estudo, objetivou-se determinar os teores de micronutrientes (Fe, Zn, Mn, B e Cu) nos diferentes órgãos do híbrido de pimentão Elisa, sob fertirrigação em ambiente protegido, em oito épocas de coleta de planta. O experimento foi desenvolvido nas dependências do Departamento de Recursos Naturais - Ciência do Solo, FCA, Botucatu/SP. Constou o experimento de 8 tratamentos (épocas de coleta de planta – 0, 20, 40, 60, 80, 100, 120, e 140 dias após o transplante das mudas) e 4 repetições, sendo cada repetição formada por 4 plantas. Em cada etapa obteve-se os teores dos micronutrientes no fruto, folha, caule e raiz e na planta como um todo. A fertilização no ciclo estudado, 140 dias, foi feita via fertirrigação localizada. Os resultados mostram que os teores de micronutrientes encontrados na planta de pimentão seguem a seqüência: Fe>Zn>Mn>B>Cu. Nos resultados são apresentadas as tabelas com os teores de Fe, Zn, Mn, B e Cu (Tukey a 5%) em cada órgão da planta e da planta como um todo, nas diferentes épocas de avaliação e, os gráficos mostrando o comportamento dos teores de Zn, Mn, B e Cu. UNITERMOS: Fertirrigação, concentrações de micronutrientes, Pimentão, Capsicum annuum L. e nutrição mineral. MACUSSI, F.F.N.; VILLAS BÔAS, R.L MICRONUTRIENT CONCENTRATION IN THE BELL PEPPER PLANT DEVELOPMENT UNDER FERTIRRIGATION 2 ABSTRACT This study aimed to determine the micronutrient contents (Fe, Zn, Mn, B and Cu) in different organs of Elisa bell pepper hybrid under fertirrigation in protected environment in eight harvesting seasons. The experiment was carried out in the Natural Resource Department – Soil Science, FCA, Botucatu. SP, and consisted of 8 treatments (harvesting season – 0, 20, 40, 60, 80, 100 and 140 days after seedling transplant), and 4 replications, each one composed of 4 plants. In each growth period the micronutrient content in the fruit, leaf, stem, root and plant as a whole was determined. The fertilization in the study period i.e., 140 days, was performed by local fertirrigation. The results showed that the micronutrient levels found in the bell pepper plant followed the decreasing order: Fe>Zn>Mn> B>Cu. The tables present the Fe, Zn, Mn, B and Cu (Tukey Test at 5%) contents in each plant organ and in the entire plant at different evaluation periods. The charts show the Zn, Mn, B and Cu content variation. KEYWORDS: fertirrigation, micronutrient concentration, bell pepper, Capsicum annuum L. and mineral nutrition.
