Effect of intercropping white cabbage with French Marigold (Tagetes patula nana L.) and Pot Marigold (Calendula officinalis L.) on the colonization of plants by pest insects

Abstract

In 2003 - 2005 the impact of intercropping white cabbage ‘Bently F1’ with French Marigold (Tagetes patula nana ‘Kolombina’) and Pot Marigold (Calendula officinalis ‘Promyk’) on the occurrence of pest insects was estimated. On plots where cabbage was intercropped the number of cabbage aphid Brevicoryne brassicae L. and flea beetles Phyllotreta was significantly lower when compared with control variant (homogenous crop). Intercropping had an effect on the butterfly oviposition too. The lower number of eggs of the small white butterfly Pieris rapae L., large white butterfly P. brassicae L., cabbage moth Mamestra brassicae L. and larvae and pupae of the diamondback moth Plutella xylostella L. were observed on plots with Calendula and Tagetes. Intercropping with Pot Marigold was the most effective pest control on cabbage.

Which companion plants affect the performance of green peach aphid on host plants? Testing of 12 candidate plants under laboratory conditions

“…The females' departure supports the idea of the repellent effect already mentioned for marigolds (Castro et al, 1990;Mauchline et al, 2005;Tomova et al, 2005;Jankowska et al, 2009;Jankowska & Wilk, 2011). The females' departure supports the idea of the repellent effect already mentioned for marigolds (Castro et al, 1990;Mauchline et al, 2005;Tomova et al, 2005;Jankowska et al, 2009;Jankowska & Wilk, 2011).…”

Effect of pot marigold (Calendula officinalis L.) and cypress spurge (Euphorbia cyparissias L.) plant water extracts on the occurrence of pest insects on white cabbage

“…A similar effect was achieved by spraying plants with French marigold (Tagetes patula) extract (Jankowska 2008). Also, the introduction of pot marigold and French marigold as intercropping plants for cabbage caused a significant increase in the number of aphids settling plants (Jankowska 2007) and other phytophags that feed on cabbage (Jankowska et al 2009 Oviposition and feeding deterrent properties are important factors in pest control, and the results of this study indicate that Calendula botanical insecticides have the potential to be incorporated into control programmes for cabbage pests. Dadang et al (2008) noted that the formulations should contain two or more plant extracts to make the formulation more effective.…”

Laboratory assessment of insecticidal properties of Tagetes minuta crude extracts against Brevicoryne brassicae on cabbage

“…Since its mode of action is described as repellency, it follows that T. minuta plants have a potential to be used in a mixed-or inter-cropping system to reduce the above listed pests against crops. This potential has already been demonstrated in a study where white cabbage intercropped with another species of tagetes (T. patula nana L.) suffered significantly less cabbage aphid infestation when compared with a mono-cropped cabbage (Jankowska et al, 2009).…”
