“…Attempts to eradicate Lantana date back to at least 1921 in India (Troup, 1921) and substantial management efforts were well under way in the 1970s in both South Africa and Australia (Bhagwat et al, 2012). Australian efforts concentrated on biocontrol, in South Africa control methods focused on mechanical removal, while in India control included these methods as well as chemical control (Babu et al, 2009; Bhagwat et al, 2012; Love et al, 2009; Priyanka & Joshi, 2013). These methods were selected to halt or slow the rapid rate of invasion and the costs, both economic and ecological, that Lantana inflicted on the ecosystems they invaded (Goncalves et al, 2014).…”

“…In a country where the typical annual salary is only about $7000 USD, this is a substantial perceived cost. Despite the importance of managing Lantana 's spread and the efforts made globally, but particularly in Australia, South Africa, and India, all eradication methods have been largely unsuccessful (Bhagwat et al, 2012; Priyanka & Joshi, 2013). Studies such as the present one are necessary to determine the recovery potential of forest under Lantana management.…”

Invasive plants adversely affect native communities by altering ecosystem function and disrupting natural regeneration. We investigate the effect of invasive Lantana camara L. (Verbenaceae) on forest regeneration in Kibale National Park, Uganda. We appraise the efficacy of cutting and uprooting Lantana for promoting native tree recruitment. Sample plots comprised three types: (i) currently invaded by Lantana; (ii) cleared of Lantana and now managed; and (iii) forest reference plots uninvaded by Lantana. Tree species numbering 51, 19 shrubs, and 17 herb species were identified.Lantana reduced tree, shrub, and herb cover and diversity, and suppressed tree regeneration. The short-term management of Lantana did not promote tree establishment.The tree community in cleared areas was not converging on uninvaded adjacent forest. Lantana is known to allelopathically suppress tree seedling establishment, but even at sites cleared of Lantana, tree species recruitment was poor. While insufficient time may have passed for tree recruitment, we argue that an increase in shrub and herb cover and diversity arrested forest tree regeneration. Sustained follow-up clearing of dense secondary shrubs and herbs and resprouted L. camara in cleared areas is key to ensuring long-term recovery of the forest tree community.

“…Its height and width are about one to six and three to five feet respectively (Saraf et al, 2011). Lantanas show a remarkable ability to thrive in environments with high salt content, nutrient-deficient soil, and limited water availability (Priyanka et al, 2013). It is usually found in subtropical and tropical areas of America.…”

Leishmaniasis is a parasitic infection caused by Leishmania species of protozoan parasites, which affects millions of people all around the world. It is transmitted by the bite of infected sandflies and can cause a range of symptoms such as skin lesions, fever, splenomegaly, and hepatomegaly. Currently, there is no vaccine developed to control this disease and the available treatment options are limited and usually come with side effects. However, medicinal plants have been investigated for their potential anti-leishmanial effects, and some have shown promising results. One such plant is Artemisia annua, also known as sweet wormwood. It contains artemisinin. Studies have demonstrated the efficacy of artemisinin against several species of Leishmania parasites. Another plant such plant is Lantana camara, commonly known as red sage in the English language. It has shown leishmanicidal effects both in in vitro and in vivo studies. The organic extracts of L. camara have shown potential activity against Leishmania species, especially Leishmania major. Other medicinal plants that have been investigated for their potential anti-leishmanial effects include Berberis vulgaris, Ferula macrecolea, and Calendula officinalis. Extracts of these plants have shown activity against Leishmania parasites in various studies. The major active constituent of Berberis vulgaris, berberine, hinders the growth of different parasitic forms of the Leishmania parasite. The roots of B.vulgaris are highly efficacious against certain species of Leishmania including L. tropica, L.donovani, and L. infantum. The essential oil Ferula macrecolea works against L. tropica whereas the methanolic extracts of Calendula officinalis are found effective against L.major. Overall, medicinal plants offer a promising approach for the development of new anti-leishmanial treatments.

“…Indigenous Africans have long used insecticides derived from plants and other organisms for a variety of reasons, which include but not limited to insect pests' management (Deng et al, 2009) (Mugisha-Kamatenesi et al, 2008). Priyanka et al (2013), reported that, Lantana Camara is one of the pesticidal plants from the family Verbenaceae. Its leaves and flowers contain compounds like ursolic acid and stearoyl glucoside (UASG) (Kazmi et al, 2017), which are associated with toxicity includes triterpenoids in a polar phase.…”

Insect pests are a major problem in cowpea production. Synthetic pesticides are used to control; however, are non-friendly to human and diversity of organisms. These negative effects raise farmers' interest in botanical pesticides due to less harmful effects on the ecosystem. Tephrosia vogelii extracts, rabbit urine, and sunflower oil were assessed for synergistic effects against cowpea field’s insectpest’s including aphids, pod borer, leaf miner, and beneficial insects. The ingredients were combined in ratio of 10% (w/v) Tephrosia Vogelii (T), 50% (v/v) rabbit urine (U), and 10% (v/v) of sunflower oil (O), while unsprayed plots and synthetic pesticide (Lambda- cyhalothrin 2.5 EC) were control negative and positive, respectively. The experiment was laid down in randomized complete block design (RCBD) with three replications. Spraying was done weekly where abundances for insects were recorded a day before next schedule. Results showed significant difference P≤0.001 in insect pest counts between treatments. The positive control exhibited smaller mean number (4.3 ± 0.3 d, 4.7±0.3 a and 5.0±0.6 a), followed by combined formulation OUT at a mean (11.0 ± 0.6 c, 8.0±0.6 b, and 4.3±0.3 a) for aphid, leaf miner, and pod borer respectively compared to negative control and individual ingredients (O, U and T) evidencing synergy. The results also indicated the combined formulation (Oil, rabbit urine and Tephrosia) OUT showed comparable yield of (846.1 kg/ha) with control positive (794.6 kg/ha) while uncombine formulation and negative control showed lower yield of 520.6 kg/ha, 611.1 (kg/ha), 662.2 kg/ha, and 483.3 kg/ha respectively. Based on the results, OUT-formulation exhibits synergy for managing cowpea’s insectpest’s, however study on cost-benefit is recommended.
