A total of 13 strains of oilseed Brassica genotypes were evaluated for their reaction to white rust pathogen Albugo candida Pers. Kuntze during crop seasons 2007-08, 2008-09 and 2009-10 at five agroclimatically diverse locations in India. Aided epiphytotic conditions were provided to ensure heavy disease pressure at all the locations. The disease reaction of different genotypes was recorded at 100 days after sowing (DAS) as per cent disease severity based on per cent leaf area affected by the pathogen. Genotypes exhibited variable disease reaction in space and time indicating the prevalence of different isolate(s) of the pathogen. However, some genotypes like PBC 9221, EC 414299 and GSL-1 exhibited resistant reaction to white rust pathogen across the locations consistently during the three cropping seasons. Some of the genotypes showed specific resistant disease reaction at a specific location indicating their suitability for cultivation at that particular location. For example, JMM 07-1, JMM 07-2 and JYM 10 have shown specific resistance reaction to isolate(s) of white rust at Morena location. It can be concluded from the study that some of the genotypes showed resistant reaction to prevalent isolates of an area. Thus, it is advised to test the genotypes for the reaction to a particular/range of diseases for the specificity in performance, if any, before release for general cultivation in a particular area. © 2014 Springer Science+Business Media Dordrecht.

Among various treatments, cypermethrin 0.01 per cent had maximum ovicidal action (97.12%) which was significantly superior to all the treatments. Quinalphos 0.05 per cent and chlorpyriphos 0.08 per cent ranked second most effective treatments achieving 96.57 and 94.10 per cent egg mortality. Neem leaves extract suspension 5 per cent (32.75%) and pudina leaves extract suspension 5 per cent (41.15%) were least toxic on the eggs of E. vittella.

Among the tested Bt cotton, square damage due to spotted boll worm on Rassi-II (T), RassiRCH-515 BG II, Super Maruti 441, Bioseed gabbler Bt, Dollar Maruti KDCHH-9810 Bt was 3.10, 2.40, 2.33, 2.85 and 2.87 per cent, respectively. While green boll damage due to spotted bollworm on Rassi-II (T), Rassi-RCH-515 BGII, Super Maruti 441 (Krishidhan), Bioseed gabbar Bt, Dollar Maruti KDCHH-9810 Bt was 1.13, 1.28, 0.98, 1.09 and 1.23 per cent, respectively. Super Maruti 441 had lowest square and green boll damage. These varieties were free from the attack of H. armigera.

Sunflower necrosis disease (SND), observed during 1997 in India has now become established in all major sunflower-growing states and has assumed the status of disease of national importance, thereby threathening sunflower cultivation in general. As It is a new disease, reliable resistance sources are still under Investigation. A new insecticide thiomethoxam (Cruiser 70 W.S.) was tested for three years at Oilseeds Research Station, Latur (M.S.), India, to manage the necrosis disease in the current sunflower production. The three-year data (2006-2008) revealed that the sunflower necrosis disease can be managed by treating seeds with thiomethoxam at 4 g/kg along with two sprays of the chemical at 0.05% 30 & 45 DAS.

Conservation of Deo-rahati (sacred grove) in India has ancient roots from Vedic period. Even in modern days ethnic groups conserve religiously preserved forest patches through their customs, taboos, and local festivals associated with the deities. Therefore, these forest pockets serve the vital function of conserving biological diversity and natural water streams. There is an urgent need of awareness and plantation around the sacred groves to fulfill the need of local people and provide protection to sacred groves.
