Curcuma longa (turmeric) is a small rhizomatous perennial herb of Zingiberaceae (Ginger family) originating from south eastern Asia, most probably from India. The plant produces fleshy rhizomes of bright yellow to orange color in its root system, which are the source of the commercially available spice turmeric. In the form of root powder, turmeric is used for its flavouring properties as a spi...

Summary Allelopathic effects of different plant allelochemicals have become the focus studies that aim to determine new pesticidal compounds. Plant extracts with chemical compositions can be obtained using methods extraction, whereas dealing allelopathic properties use biotests obtain fast and precise results. Such were undertaken after noticing industrial hemp (Cannabis sativa L.) on surroundi...

Background: Aquatic pollution by pesticidal application, in recent times, has gained much attention throughout the world, as they ultimately reach to the aquatic bodies through agricultural runoff or by aerial spraying and finally, impair the health status of fish. The aim of the present study was to evaluate the toxicological responses of Almix® herbicide on oxidative stress parameters in thre...

Medicinal and pesticidal plant propagation is hampered by poor seed germination due to dormancy. This study aimed enhance seedling growth using various pre-sowing treatments. A triplicated two-factor experiment in a Randomized Complete Block design was used. Soaking water at 25°C for 24 h (T1), soaking 60°C hot 10 min (T2), ppm Potassium nitrate (KNO3) treatment (T3), 20 (T4), Treating ...

In continuation of our program aimed at the development of natural product-based pesticidal agents, three series of novel camptothecin derivatives were designed, synthesized, and evaluated for their biological activities against T. Cinnabarinus, B. brassicae, and B. xylophilus. All of the derivatives showed good-to-excellent activity against three insect species tested, with LC50 values ranging...

Recent advances in paint technology have guided the development of novel “ready-to-use” paint formulations in which microencapsulated insecticides, or active ingredients (AIs), are embedded in the paint matrix and gradually released on the surface of the dried paint [1]. It is argued that the slow-release mechanisms enable uniform AI surface concentrations with prolonged residual effect, as com...

Rhinacanthus nasutus is an ethnomedical plant used in the traditional system of medicine for treating skin diseases. As no adequate studies available on R. grown Sri Lanka, this study aimed exploring anti-oxidant, anti-parasitic and pesticidal activity leaves plant. Antioxidant capacity crude extract was evaluated using DPPH free radical scavenging assay FRAP ascorbic acid FeSO4.7H2O as standar...

The rising concern regarding the negative impact of synthetic pesticides has led to search for alternative means pest control. Vermicomposting mixture oil palm empty fruit bunch and neem (Azadirachta indica) leaves, with latter known have pesticidal value, is therefore great interest significance be studied. present study was conducted evaluate chitinase, protease β-1,3-glucanase activity leaf-...
