Black and Zimmerman proposed that inorganic substrates with coal slag could be suitable for rooting cuttings.

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

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. The collection site for each of the accessions is shown in Tab. Regarding marigold plants Table 1 we found more richness and abundance of parasitoids compared to onion plants, since those plants produce pollen and nectar that potentially can sustain parasitoid populations Baggen, In spite of these similarities, the main phytophagous species collected, T.

In the case of the species T. Dissecting Arabidopsis lateral root development.

The flowers are cultivated, picked and processed in an important one scale industrial as source of high color value, of the family of the carotenoids.

The rooting of cuttings of L.

Direct differentiation of shoot buds in leaf segments of white marigold Tagetes erecta L. Micropropagation of Lippia junelliana Mold. The form of use of the marigold is as dehydrated petals and concentrated, tagetws are used as addictive in the feeding for improvement of the skin pigmentation and eggs of poultry.


Taking into account these facts, the objective of this study was to contribute to the establishment of the aromatic species L. However, the efficacy of such plant extracts has not been proved yet, and it was observed that they do negatively affect natural enemies.

Coconut fiber is a substrate with good buffering and high water retention capacities, which are useful for reducing the frequency of irrigation; and has a low bulk density Quintero et al.

How to cite this article. Fitopatologia Brasileirav.

Historical and ethnobotanical aspects of domestication in Tagetes. Annual Review of Entomologyv. Eighteen taxa 5 m from marigold and only ten 30 m from marigold plants were found, as well as nearly twice as many natural enemies near to as far from marigold strips, 0. The use of this plant may contribute to management of onion pests, mainly the thrips, because the increase of the number of predators would promote lowering costs in pest control, thus, turning the organic onion crop more sustainable.

Cultivo del marigold: efecto en el control de nematodos [1982]

Verificou-se o efeito de linhas de cravo-de-defunto Tagetes erecta L. This study was set in a particular situation and therefore the data would probably not fit the expectations of other people working on organic agriculture in other conditions.

Services on Demand Journal. The propagation and evaluation were carried out in greenhouse conditions at the facilities of the Universidad Nacional de Colombia, Bogota, located at 2, m a.



Labiatae is a promising thrips repellent which could be used for further testing in a pushpull system. Seeds for germination tests were harvested two d before the tests from 4 month-old stock plants.

The diversity index H’ was higher at 5 m from the marigold strip, indicating that dominance of species is slightly lower than at 30 m erwcta the marigold strip.

As stated by Visserphytophagous insects respond to a complex mixture of plant odors to recognize their hosts.

The experiment was conducted with a completely randomized design and a 3 x 3 factorial arrangement factors: In a previous study, several non-domesticated wild species of the genus Lippia from Brazil L.

Again, there are no propagation methods established for T. For the asexual propagation of this species, the substrate FCF may be used because this seems to promote rooting, and auxin may be added to promote the growing of more roots.

Schiavon, Diane Bender Almeida Published: There was a slight dominance of phytophagous species at the beginning and at the end of flowering periods the aphid A. Therefore, the main phytophagous species were more abundant in onion plants 30 m from marigold, while the main predators were more abundant in plants close to the attractive species.

The analysis of similarity indices between marigold developmental stages Table 2 indicated that there is greater similarity between the onset and peak flowering periods for phytophagous
