“…Ao trabalharem com plantas de Ocimum basilicum L., Luz et al (2014) mostraram que o uso de substratos não proporcionou diferenças estatísticas significativas no aumento de massa seca, porém em plantas de "mil-folhas", Ferraz et al (2014) comprovaram que a presença do esterco bovino favoreceu o acúmulo de massa seca da parte aérea. Para a formação de massa seca total, o esterco bovino proporcionou às plantas de orégano 83 g, em média.…”

“…Além disso, as respostas positivas das plantas de orégano podem ser justificadas porque esta cultura possui boa aceitação à adubação orgânica, assim como a maioria das plantas, independente da família botânica a que pertençam. Para a quantidade de massa seca em plantas de "milfolhas", Ferraz et al (2014) encontraram resposta linear quando foram usadas doses crescentes de adubos orgânicos. Ou seja, à medida que a dose do adubo orgânico aumentou, houve maior incremento de massa seca nesta planta.…”

Resumo: O orégano é uma das plantas aromáticas e condimentares mais utilizadas no Brasil e a maior parte do produto consumido é proveniente de importação, mesmo o País apresentando condições de clima e solo favoráveis para o cultivo desta erva. Este trabalho teve como objetivo avaliar o efeito da adubação orgânica e mineral em plantas de orégano cultivado sob malha colorida. Foi adotado o esquema fatorial 4x4 (sendo quatro ambientes de luz modificada e quatro fontes de nutrientes: Latossolo Amarelo, esterco bovino, composto orgânico e NPK), adotou-se o DIC com seis repetições. Avaliaram-se as seguintes características de crescimento: altura das plantas, produção de massa seca e razão de peso foliar. Constatou-se que as plantas adubadas com esterco bovino obtiveram maior altura e maior produção de massa seca; e as plantas cultivadas no ambiente protegido pela malha azul tiveram maior altura, massa seca de raiz e massa seca total.Palavras-chaves: fertilidade do solo, nutrição de plantas, plantas aromáticas, Origanum vulgare. Abstract:The oregano is one of aromatic and spice plants most used in Brazil and the more part of the to consumption comes from imports, even the Country presenting favorable conditions of soil and climate for growing this herb. This study aimed to evaluate the effect of organic and mineral fertilizer in oregano plants cultivated under colored mesh. It was adopted a factorial scheme 4x4 (four modified light environments and four sources of nutrients: Oxisol, bovine manure, organic compound and NPK), was adopted the DIC with six replications. We evaluated the following growth characteristics: plant height, dry matter yield and leaf weight ratio. We evaluated the following growth characteristics: plant height, dry matter yield and leaf weight ratio. It was found that plants fertilized with bovine manure had presented greater height and higher production of dry matter; and plants grown under blue net had greater height, root dry weight and total dry mass.

“…The essential oil (EO) of yarrow is deep blue in colour (Ferraz et al, 2014), and it has been attracting the attention of many researchers owing to its broad applicability, such as anti-inflammatory (Chou et al, 2013), antimicrobial (Mahmoudi et al, 2016), antioxidant (Dolwitsch et al, 2016) and insecticidal (Tampe et al, 2015) activity. Dias et al (2000) proved the nematostatic activity of yarrow aqueous extracts in M. incognita, which ranged from 78.25% to 94.4%.…”

Pratylenchus brachyurus is a phytonematode species mostly damaging crops. It is mainly controlled by agrochemicals which are harmful to the environment and public health. Such outcomes encourage the development of research on products and/or processes to control this phytonematode and to contribute to the sustainability of agricultural systems. Thus, the aim of the current study was to assess host suitability of Achillea millefolium to P. brachyurus, as well as the nematicidal potential of its essential oil and root exudates. We conducted two experiments with two different plant species-Glycine max (soya bean) and Achillea millefolium (yarrow)-based on a 2 × 3 factorial arrangement to assess host suitability. Plants were assessed 5, 10 and 15 days after inoculation through the fuchsine acid staining technique. Based on the results, A. millefolium was an unfavourable host to this phytonematode. Therefore, it can be recommended for crop rotation and/or succession systems in small areas. We tested the nematicidal activity of the essential oil and exudates of A. millefolium at concentrations of 0, 25, 50, 100, 200, 300, 400 and 500 µg/ml in a BOD incubator at 26°C for 48 hr. The essential oil showed increasing linear regression, that is the higher was the concentration, the higher was the mortality rate. Exudates showed a quadratic behaviour (p ≤ .05), leading to 60.83% nematode mortality. Therefore, the essential oil and root exudates of A. millefolium have the potential to control P. brachyurus. The essential oil showed antagonistic properties likely because of the presence of germacrene D (39.55%), (E,E)-α-farnesene (25.70%) and chamazulene (8.91%).

Could alternative solanaceous hosts act as refuges for the tomato leafminer, Tuta absoluta?

The tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae), is a widespread devastating pest reported to develop on economically important solanaceous plants. The characterization of its effective host range could help to understand and prevent the dispersion behavior of the insect in the environment. In this study, the ability of T. absoluta to locate and develop on wild (Solanum nigrum, Atropa belladonna, Datura stramonium) and cultivated (Solanum tuberosum) solanaceous plant species under laboratory conditions was assessed. Dual-choice behavioral assays performed in flying tunnels (S. tuberosum vs. another plant) revealed that adult distribution and female oviposition did not differ between Solanum species, which were preferred to the other tested plants. The volatile molecules released by each tested plant species provide some explanations in the observed behavioral discrimination: S. nigrum and S. tuberosum volatile profiles were similar and were presenting quantitative and qualitative differences with the other tested solanaceous plants. To determine whether the host plant choice was adaptive or not, we have finally conducted fitness assays, by rearing T. absoluta larvae on each plant species and have shown that Solanum species allowed higher larval survivability and lower development time (from egg to adult emergency) compared to the other plants. We conclude that Solanum species are suitable host plants for T. absoluta, but other solanaceous plant species could be opportunistically colonized with fewer incidences.
