This low competitiveness is due to various factors, one of which is the lack of technology for mass propagation and crop management, and the lack of knowledge of the potential of native species that offer better alternatives for production and marketing. There was a higher number of phytophagous arthopods m -2 in onion plants far from marigold 30 m. In the case of the species T. The mathematical theory of communication.

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. The trays with the cuttings were distributed on a raised greenhouse bed and moistened with a micro spray system with micro sprinklers 40 L h -1 spaced every 30 cm, using a run time of 5 min d Wageningen, The Netherlands; St. Thus, further tests could be necessary to clarify the role of marigold plants near the onion crop in other areas.

Salud UIS 41, Composition of the essential oil from leaves of Tagetes zipaquinensis Hump. The opposite was observed with predators, especially Stomatothrips angustipennisStomatothrips rotundus and Franklinothrips vespiformis Thysanoptera: For the samples on marigold strips, species dynamics varied depending on the developmental stage, abundance and similarity Tables 1 and 2but not for richness: This is an indication that few phytophagous species were found at both plant species, except for A.



The cuttings were immersed for 5 min in liquid solution at different concentrations of the hormone indolebutyric acid IBA and were subsequently planted in germination trays with 24 wells, with dimensions of 5. These percentages of germination are relatively high when compared with germination in other wild species of the genus, such as Tagetes lucida, which presents a large number of sterile seeds Acosta de la Luz et al.

In this field there is a positive effect of marigold rows on natural tabetes abundance and negative effect on pest insect abundance. Furthermore, in Colombia, edecta and processors of aromatic plant species face various limitations, including issues of quality, performance and traceability for processing.

Cuttings were planted in germination trays, covered with transparent plastic to maintain high humidity and irrigated with a micro spray system. Marigold Tagetes erecta L. Conclusions The rooting of cuttings of L.

We performed an ANOVA with the average calculated over seven weeks of sampling, showing patterns of weekly abundance but performed statistical analysis for the whole period of the errecta.

Colombia has unexplored flora with good potential for the production of EO.

Again, there are no propagation methods established for T. 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, First of all, the calculated collection curve indicated that the samples taken from onion crop were enough to collect the majority of species present in the crop during the experiment.

The results of this study are consistent with previous reports on L. So these low natural enemies’ similarities between marigold and onion indicate that not the same but different species were found on onion near attractive plants.


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

Rev Cubana Plant Med. Direct differentiation of shoot buds in leaf segments of white marigold Tagetes erecta L. The same test was performed in germination trays with peat TRM7, with two replicates of 50 seeds, arranged in a greenhouse.

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.

Black and Zimmerman proposed that inorganic substrates with coal slag could be suitable for rooting cuttings. A study for the development of a handbook of selected Caribbean herbs for industry.

Organic onion farming is expected to increase in the state due to the increasing demand.

Figure 2 compares the overall development of the evaluated accessions of L. Anyway the data of the association of marigold plants and onion crops will certainly help organic onion growers mainly in reducing the production costs.

The form of use of the marigold is as dehydrated petals cuktivo concentrat This dominance of phytophagous taxa in the beginning and the end of marigold flowering periods, however, did not produce a great impact on the onion field, because insects using marigold as a host plant e. On the other hand, root dry weight was not affected by substrate or IBA concentration. How to cite this article.
