“…comm.). In addition, other studies have shown S. guianensis to have a nematicidal effect on another root-knot nematode species, M. exigua, in Brazil (Amaral et al, 2009), and it cannot be excluded that this is also the case for M. graminicola. Therefore, additional studies are needed to evaluate the direct effect of the cover crops.…”

Rice production in Southeast Asia is significantly affected by root-parasitic nematodes (RPN). The Green Revolution has encouraged new agricultural practices (e.g. intensive monoculture, high yielding rice variety) to respond to the high rice demand; however, these methods have promoted the spread of these pests. The recent banning of chemical nematicides resulted in a need for alternative sustainable control strategies. In the present study, we assessed the effects of a direct-seeding mulch-based cropping system (DMC) vs conventional plough-based tillages (CT) on soil properties, rice yield and RPN communities during a two-year trial in Cambodia. Our results show that on average the population densities of RPN were significantly higher in DMC than in CT. Molecular identification revealed only two RPN species associated with roots: Meloidogyne graminicola, not previously reported from Cambodia, was predominant and was present throughout the plant's development, whereas Hirschmanniella mucronata was only found at the tillering and milky stages. We conclude that DMC had a significant positive impact on rice yield, despite higher RPN short-term pressure. In order to increase the efficiency of such cropping systems, further studies and an evaluation of the long-term relationships between DMC, the nature of cover crops used, the soil biota including RPN, and rice yield should be conducted.

“…The ricinine present in castor pollen can be toxic to social bees ( Apis mellifera L. and Scaptotrigona postica Latreille) (Rother et al, 2009; Assis et al, 2011). When extracts and powders derived from castor leaves were found to suppress parasitic nematode growth, ricinine was thought to be the active compound (Radwan et al, 2007; Amaral et al, 2009; Katooli et al, 2011; Lopes et al, 2011).…”

“…Castor leaves increased the effect of castor meal against M. incognita attacking lentil ( Lens culinaris Medikus) and okra ( Abelmoschus esculentus L.) plants (Wani, 2006). An extract of castor leaves killed 86% of M. exigua juveniles J2 in coffee plants ( Coffea arabica L.) (Amaral et al, 2009). Castor leaf extract was more effective than carbofuran against M. incognita attacking tomato plants (Radwan et al, 2007).…”

A Review on the Challenges for Increased Production of Castor

et al. 2012

Castor (Ricinus communis L.) is one of the oldest cultivated crops, but currently it represents only 0.15% of the vegetable oil produced in the world. Castor oil is of continuing importance to the global specialty chemical industry because it is the only commercial source of a hydroxylated fatty acid. Castor also has tremendous future potential as an industrial oilseed crop because of its high seed oil content (more than 480 g kg−1), unique fatty acid composition (900 g kg−1 of ricinoleic acid), potentially high oil yields (1250–2500 L ha−1), and ability to be grown under drought and saline conditions. The scientific literature on castor has been generated by a relatively small global community of researchers over the past century. Much of this work was published in dozens of languages in journals that are not easily accessible to the scientific community. This review was conducted to provide a compilation of the most relevant historic research information and define the tremendous future potential of castor. The article was prepared by a group of 22 scientists from 16 institutions and eight countries. Topics discussed in this review include: (i) germplasm, genetics, breeding, biotic stresses, genome sequencing, and biotechnology; (ii) agronomic production practices, diseases, and abiotic stresses; (iii) management and reduction of toxins for the use of castor meal as both an animal feed and an organic fertilizer; (iv) future industrial uses of castor including renewable fuels; (v) world production, consumption, and prices; and (vi) potential and challenges for increased castor production.

“…Trabalhos também relataram que o extrato aquoso é nematicida em plantações de tomate (JUNGES et al, 2009;MATSUMOTO et al, 2002;NACHTIGAL;SCHNEIDER, 2007), porém, há trabalhos que afirmam que este extrato aumenta o número de ovos, tornando assim a planta como hospedeira de nematóide em plantações de café (AMARAL et al, 2009;PONTE et al, 1996). Navarro e Barriga (1970) citaram a planta como resistente aos nematóides.…”

Tagetes minuta L. é uma planta aromática vulgarmente conhecida como chinchilho, cravo-de-defunto, chinchila, picão-do-reino entre outros. O objetivo do trabalho foi executar uma revisão sistemática sobre Tagetes minuta com a finalidade de identificar os principais componentes químicos, usos populares e atividades biológicas. Como estratégia de busca da revisão sistemática, a palavra-chave “Tagetes minuta” foi utilizada no Scielo, Pubmed e Google acadêmico. Na pesquisa inicial, foram identificadas 429 publicações, sendo 384 no Google acadêmico, 9 no Scielo e 36 no Pubmed. Após a leitura do título e do resumo, foram avaliados 111 trabalhos por se enquadrarem dentro dos critérios de inclusão. Na segunda etapa, foi realizada a leitura da publicação e se estas se enquadravam nos objetivos do trabalho, a publicação era selecionada. Com este procedimento, 51 publicações foram escolhidas. A revisão sistemática mostrou que a planta Tagetes minuta, além de ser popularmente conhecida por indicações medicinais, foi cientificamente testada e apresentou atividade antibacteriana, antifúngica, larvicida, inseticida, antiparasitária, nematicida, anti-hiperglicêmica, antitumoral, biocida e antioxidante.
