Botanical pesticide and insects repellent prepared from Tanacetum baltistanicum endemic to Gilgit-Baltistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 5
Abstract
Conventional pesticides and antiseptics are no more attractive for consumers where biotechnology and hyphenated state of art techniques are available to bring innovation and discoveries. The shift from the current, conventional market to new greenest paradigm can be possible by rational identification and amplifications of botanicals. These botanicals, in turns can be applied on field or processed further for better action and efficacy. The mountainous region of Gilgit-Baltistan (G-B) is one of the most appropriate places with huge and unique floral diversity having great potential for such discoveries. During the current study the four different solvent extracts from Tanacetum baltistanicum, an endemic species to G-B was thoroughly investigated to determine its antiseptic potential. The toxicity of only 1% w/v aqueous solution of ethyl acetate, methanol and water extractives against woolly or apple aphids: Eriosoma lanigerum (Hemiptera: Aphididae), mealy cabbage aphids: Brevicoryne brassicae (Hemiptera: Aphididae), cabbage caterpillar: Pieris brassicae (Lepidoptera: Pieridae) after 24 hours was found in the range of 85-95% population mortality, while hexane extractive from T.baltistanicum was interestingly found 100% repellent against Sri Lankan weevil: Myllocerus undecimpustulatus undatus (Coleoptera: Curculionidae) on pear plants. This is worth to mention here that no damage to any pods was observed during and after the application of the formulations.
