商品簡介
Weeds are considered a weapon used by the enemy. Since the beginning of agriculture, humans have struggled with weeds. In the 18th century, Warren Hastings, the first Governor-General of Bengal, brought water hyacinth from South America as a gift for his wife, Marian Hastings, because she liked its flowers. Parthenium hysterophorus was introduced into India through the distribution of food grains to developing countries under Public Law 480, which aimed to combat starvation and malnutrition. During the British colonial and post-colonial periods, the British government introduced and promoted Prosopis juliflora to control arid lands, combat deforestation, and provide firewood. Mikania micrantha was introduced to India in the 1940s to camouflage airfields during World War II and to serve as ground cover in tea plantations. Ageratum conyzoides was introduced as a contaminant in seeds of other garden plants.Likewise, many alien weeds have entered India, causing major economic and environmental losses by reducing agricultural yields, diminishing biodiversity, and degrading ecosystems. This 130-page book provides a detailed account of the toxic effects of invasive alien weeds in India.
