Management of powdery mildew and aphid in organically grown Indian mustard (Brassica juncea L.) through different oils

چکیده
All the cultivated Brassica species exhibited powdery mildew severity with highest (43.2%) on juncea followed by B. rapa (28.0%) which is widely in India. Yield losses from 10-90 per cent reduction 6.47 oil content have been estimated different species. Hence, present study was carried out to evaluate oils manage disease and aphids an organically grown mustard crop. Five (castor, groundnut, sunflower, neem oil) ghee were evaluated against (Erysiphae cruciferarum) aphid (Lipaphis erysimi) of Indian (Brassica juncea). Castor 50 EC, EC deshi (@ 100 ml/10 litre water) effective over untreated control reducing when applied as foliar spray 5 ml/litre) experiment organic field (plot No. B-2 at Agronomy Instruction Farm, S. D. Agricultural University, Sardarkrushinagar). Maximum germinated conidia (66.0%) control, (50.0%), area under progress curve (AUDPC) values (51.8%) maximum increase 1000 seed weight (16.7%) yield (10.3%) observed oil. This application reduced (22.9%) AUDPC (30.6%) increased (8.1%) castor (8.0%) (20.8%). Shortest log phase during 10th std. week. tested population (39.5 65.9%) damage index (6.1 25.1%). A (65.9%) lowest (3.70) 6 days after 2nd spray. Application oil, resulted (8.1 10.4%). information could be useful devising strategies for management cultivation, eco-friendly IPM mustard.

ASSESSING APHID INFESTATION IN INDIAN MUSTARD (Brassica juncea L.) UNDER PRESENT AND FUTURE CLIMATE SCENARIOS
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 sho...

Plants, in general, are put to various kinds of stress, biotic and abiotic, both natural and manmade. Infestation by insect pests and diseases, and extreme conditions such as salinity, temperature, etc., as well as heavy metal contamination affect their growth performance. Here, we studied the impact of salinity and heavy metal pollution on the growth performance of Indian Mustard Brassica junc...

Salinity stress affected crop production of more than 20% of irrigated land globally. In the present study the effect of different concentrations of NaCl (0, 100, and 200 mM) on growth, physio-biochemical attributes, antioxidant enzymes, oil content, etc. in Brassica juncea and the protective role of Trichoderma harzianum (TH) was investigated. Salinity stress deteriorates growth, physio-bioche...
