Bio-Efficacy Of Some Plant Leaf Extracts Against Mustard Aphid,Lipaphis ErysimiKalt. On Indian Mustard,Brassica JunceaThe bio-efficacy of four plant leaf extractsviz., apple of sodom,Calotropis proceraAiton; Mexican poppy,Argemone mexicanaLinnaeus; Mexican marigold,Tagetes minutaLinnaeus and Indian neem,Azadirachta indicawere tested against mustard aphid,Lipaphis erysimion Indian mustard,Brassica juncea. The highest per cent aphid reduction during first, second and third spray were 28.79, 40.52 and 59.32 at 1 : 10 g/ml; 34.70, 44.49 and 66.14 at 1 : 5 g/ml and 53.88, 64.84 and 100.00 at 1 : 2.5 g/ml with Indian neem. However, Mexican marigold was also effective at highest concentration (1 : 2.5 g/ml) and reduced 96.38 per centL. erysimi. All the treatments of plant leaf extracts showed insecticidal activity, but Indian neem followed by Mexican marigold reduced the aphid population to a great extent.

Functional Relations

Mustard (Brassica juncea L.) production in India suffers from aphid, Lipaphis erysimi (Kaltenbach), infestation considerably. Role of weather on the incidence and development of mustard aphids was assessed from experimental data from six north Indian locations. Aphid appearance and population build up was found to be regulated by temperature and time to attain peak population was relatively short in warm humid climates than in cool climates. Aphids appeared generally when the accumulated thermal time ranged between 810-847 and diurnal temperature range had a key role on the pest build up. Functional relations developed from the present study between aphid incidence and peak population using previous weeks weather and pest data for majority of the locations could be used for taking of any prophylactic/control measures. Projections on aphid population in future climates using generated weather variables indicated that warming may not increase aphid population at all locations uniformly.
