RESEARCH at the Delhi-based Institute of Nuclear Medicine and Allied Sciences (INMAS) have developed an ecofriendly and biodegradable insecticide from marigold flowers. Scientists have found that 2 compounds present in the flower -- alphateriophene, or alpha-T, and erythrosin-B -- are effective against the larvae of the malaria-causing Anopheles mosquito as …
INSECTS destroy a major part of standing crop, damaging the predominantly agrarian economy of the developing countries. That traditional pesticides are indisputably environmentally detrimental is an established fact.
