Allelopathic effects of Lantana Camara Extract on weeds and cultivated crops: A systematic review
Journal Title: Journal of Agriculture, Food, Environment and Animal Sciences - Year 2023, Vol 4, Issue 2
Abstract
The current review was aimed at investigating the potential of Lantana camara extract as an effective alternative for synthetic herbicides to control weeds and also establishing the effects of allelochemicals in the extract on the germination and growth of cultivated crops. The researchers assessed abstracts and articles published from 2011 to 2022. The review has established that although L. camara extract has allelopathic properties to suppress the germination and growth of weeds in the fields. However, the extract is not entirely selective for the plants it inhibits; as a result, it also suppresses the growth of cultivated crops. Therefore, the review recommends that the extract should only be used on crops whose germination and growth cannot be suppressed by it. There is a need to establish the proper timing of the application of the extract to avoid the suppression of germination and early seedling growth in cultivated crops. More studies have been done on the effects of extract on plants in the Poaceae, Fabaceae, and Brassicaceae families. Therefore, more research has to be done to evaluate the allelopathic effects of L. camara extract on agronomic crops under Onagraceae , Solanaceae, Asteraceae, Convolvulaceae, Euphorbiaceae, Malvaceae, and Amaranthaceae families.There is limited information on the effects of the L. camara extract on the yields of the crops; as such, this review recommends that further research be conducted to evaluate the effects of the allelochemicals of L. camara on the yields of the cultivated crops in the fields where the extract has been applied.
