Globally, 1031 species of arthropods are associated with the intensively managed tea Camellia sinensis (L.) O. Kuntze monoculture. All parts of the plant, leaf, stem, root, flower, and seed, are fed upon by at least one pest species, resulting in an 11%-55% loss in yield if left unchecked. There has been heavy use of organosynthetic pesticides since the 1950s to defend the plant against these p...
background: this investigation describes the cyto-architectural alterations observed in the corpuscles of stannius of stinging catfish heteropneustes fossilis after treatment with a botanical pesticide nerium indicum. methods: heteropneustes fossilis were subjected to 11.27 and 2.81 mg/l of nerium indicum leaf extract over short- and long-term exposure periods, respectively. blood was collected...
Abstract Spodoptera exigua is a cosmopolitan and polyphagous pest. Botanical pesticides are an alternative technique to control S. . This study aimed evaluate the effect of ethyl acetate extract Nothaphoebe coriacea Kosterm bark (EEN) on biological activity larvae determine most effective concentration manage experiment was arranged single factor completely randomized design with level as facto...
In order to develop novel botanical insecticides, the joint action of Ligusticum chuanxiong oil (LCO) and lemongrass oil (LO) against Aphis citricola van der Goot was determined systematically indoors and outdoors. The chemical profiles of LCO and LO as determined by gas chromatography-mass spectrometry (GC-MS) analysis revealed that the main compounds from LCO were (Z)-ligustilide (44.58%) and...
This overview covers a wide range of cannabis topics, initially examining issues in dispensaries and self-administration, plus regulatory requirements for production of cannabis-based medicines, particularly the Food and Drug Administration "Botanical Guidance." The remainder pertains to various cannabis controversies that certainly require closer examination if the scientific, consumer, and go...
Botanical insecticides presently play only a minor role in insect pest management and crop protection; increasingly stringent regulatory requirements in many jurisdictions have prevented all but a handful of botanical products from reaching the marketplace in North America and Europe in the past 20 years. Nonetheless, the regulatory environment and public health needs are creating opportunities...
In India, the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is an important pest of cruciferous vegetables and causes severe economic losses. This pest has ability to evolve resistance in laboratory and field to almost all groups of synthetic insecticides. Despite of these, management with synthetic insecticides has been considered to be the easy and favorable option by...
Fish and other organisms are affected by pesticides which pollute the natural water through agricultural runoff. The aim of this study was to determine the acute toxicity of botanical pesticide, neem gold, and two synthetic pesticides, permethrin and monocrotophos, which are extensively used in agricultural farms. The mortality rate of Cyprinus carpio was monitored under laboratory conditions f...

BACKGROUND Pesticide-environment interactions are bidirectional. The environment alters pesticides by metabolism and photodegradation, and pesticides in turn change the environment through nontarget or secondary effects. OBJECTIVES Approximately 900 currently used commercial pesticides of widely diverse structures act by nearly a hundred mechanisms to control insects, weeds, and fungi, usuall...
