In previous studies, it has been observed that an immersion time of 5 min at different IBA concentrations is necessary to promote rooting in cuttings of other plant species Frangi and Nicola, ; Struve and Moser, Accumulation of endogenous auxins may be due to two major factors: In the same way, longer roots were observed when the hormone was not applied.

As stated by Visserphytophagous insects respond to a complex mixture of plant odors to recognize their hosts. The specie Tagetes erecta, commonly known as marigold, it is native of Mexico. The experiment was conducted with a completely randomized design and a 3 x 3 factorial arrangement factors: Plant odours with potential for a push-pull strategy to control the onion thrips, Thrips tabaci.

Lippia alba CA Tab. The cuttings were selected from the middle stratum of the plant and branches, with a size between 12 and 14 cm, 2 to 3 nodes, and semi-woody texture.

In a previous study, several non-domesticated wild species of the genus Lippia from Brazil L. In spite of these similarities, the main phytophagous species collected, T.

Entomologia Experiementalis et Applicatav. One of the strategies in the development of a production chain is the establishment of mass production of seed and planting material, which requires standardization of propagation techniques.

However, these plants, as is characteristic of native species that are often found in the wild, lack methods of propagation and agronomic management, which limits their use as potential new crops.

Marigold (Tagetes erecta L.) as an attractive crop to natural enemies in onion fields

Aeolothripidaewhich were twice as abundant in onion plants near the marigold strip. This diversity may lead to increased pest control in onion, reducing the use of plant extracts that have been shown to be detrimental to natural enemy populations.

Despite the higher variation, the number of entomophagous arthopods m -2 may explain this result, as the number of natural enemies was lower in plants localized far from marigold row, therefore resulting in higher amounts of herbivores. Arthropods were grouped in two main ecological groups: In summary, accession CA of L.

The experimental unit was composed of ten cuttings, for an experiment size of cuttings for each accession. Auxin effects on root regeneration of scarlet oak seedlings. Moreover, this study contributes to the identification of insect species occurring on both plants, providing basic information for further researches.

Ereecta results for each species are presented below. Among the promising aromatic plants for Colombia based on quality and bioactivity of essential oils are species of the Verbenaceae family such as Lippia alba Mill.

Thiophene occurrence in different Tagetes species: Ecological diversity and its measurement. In general, the average rooting percentage observed for the two evaluated accessions fultivo L. Ediciones Mundi Prensa, Madrid. Concluded that as smaller the number of flowers, larger it individual weight, with larger consequent production of petals for flower.

Tagetes erecta – Wikispecies

Syrphidae populations in relation to different plant species in rows surrounding the onion field, observed no population decrease of the pest species. The marigold strips were also sampled during the period of onion cultivation, and each sample corresponding to one square meter of crop coverage, using the same methodology as for onion plants.

One of the main recommendations for organic farming is the recovery of functional biodiversity, which is lost or very reduced in conventionally grown monocultures.

Establishing propagation methods for promising aromatic species cltivo important because there may be some relationship between the propagation method and cultural practices used and the yield and composition of essential oils and other chemical compounds. This study, however, only included abundance of thrips nymphs and syrphid larvae, and there may have been differences tagetex the abundance of other phytophagous and predatory species.

The latter species showed a relatively poor performance and may require more complex and improved propagation methods to obtain more satisfactory results.

The cultivation of native plant species, with potential uses as spices, seasonings, and sources of essential oils EO and derived products in Colombia, is an excellent alternative for growers and has a potential application in agriculture such as biological control and industry. The results of this study tageets consistent with previous reports on L.

Los factores evaluados fueron el sustrato fibra de coco fina FCF ; fibra de coco fina: Tagetes caracasana CA Germination tests were performed for T. The germination speed index GSI was 4. Marigold seed was obtained directly from field collection on the organic farm selected and cultivl the grower has cultivated it for years, there is no way to determine tahetes cultivar. Furthermore, in Colombia, producers and processors of aromatic plant species face various limitations, including issues of quality, performance and traceability for processing.

An analysis tavetes variance ANOVA and multiple comparison tests to evaluate differences between the effects of the treatments were used. Samples were taken from marigold and the onion plants 5 m near and 30 m far from the flowering strips.

Habitat management to conserve natural enemies of arthropod pests in agriculture.
