Camellia seed extract … Saponins
Saponins are phytochemicals which can be found in most vegetables, beans and herbs. The best known sources of saponins are peas, soybeans, and some herbs with names indicating foaming properties such as soapwort, saoproot, soapbark and soapberry.
Saponins are natural surfactants, or detergents (natural soapy substances) with distinct foaming characteristics, natural adjuvant of non-ion surface-active agent extracted from plants. It has high toxicity to cold-blooded animals, non-toxic to low toxicity to humans and animals, such as warm-blooded animals. They are found in many plants and are the plant’s “immune system”. Natural soaps are an important weapon in the armory that plants deploy to protect against disease attack. Many plants produce natural soaps (called saponins). These chemicals are toxic to bacteria and fungi and so form part of the plant’s protection against disease. Researchers have known for some years that microbes that can successfully infect saponin-containing plants often produce enzymes that break down the saponins into less toxic chemicals. This enables the invader to breach the plant’s first line of defense.
Saponins possess clear insecticidal activities: they exert pesticidal action against a broad range of pest insects that is different from neurotoxicity. The most observed effects are increased mortality, lowered food intake, weight reduction, retardation in development and decreased reproduction. According to the main hypotheses in literature, saponins exert a repellent/deterrent activity, bear digestive problems, provoke insect moulting defects or cause cellular toxicity effects. As a consequence these interesting plant components open new strategies to protect crops in modern agriculture and horticulture with integrated pest management (IPM) programs against pest insects, either by spraying or irigation.
Saponins, as a biological pesticide, it could also be used as insecticide, fungicide, snarlcide, as a clean-pond agent, it can eliminate unwanted fish in the ponds for its haemolysis and accelerate growth of shrimp. It is difficult to prevent and kill underground injurious insect, but the specialized insecticide which mainly contains tea saponin, not only effectively kills cutworm, earthworm, nematode, etc., but also no pollution in soil.
Saponins can be widely applied in various forms of pesticides for leaf spraying to provide quick wetting, more uniform coverage and increase retention of sprays by reducing the surface tension of the spray droplets on the leaves. It can form a thin film on the leaves of plant, increasing humid, spreader and permeability, reduce the plant surface wastage and accelerate the absorption and plants conduction, with the capacity of weather resistance, hence to improve efficacy, reduce the use of pesticide and lower the costs. Although, tea saponin has effects on pests/diseases and stomach poisoning effect, but tea saponin has slow-acting effect, and the effect of using alone is not good.
