Farmers from plain areas have suffered huge losses.[In some areas] yellow rust has caused damage to wheat crops [with] nearly 25 per cent [of the] crop affected in the last 3 weeks. Farmers are now facing the problem [that] yellow rust may further aggravate and would spread with improvement in weather.[The Department of] Agriculture, Jammu, said that over 1200 ha [about2965 acres] have been affected by yellow rust. They are providing guidelines to farmers and treatment of affected crops.[Byline: Gopal Sharma]--Communicated by:ProMED-mail<promed@promedmail.org>[Stripe rust (also called yellow rust) of cereals is caused by the fungus _Puccinia striiformis_ (previously var. _striiformis_ or _tritici_). The disease affects wheat, some barley varieties, triticale, and a number of wild grasses. It causes yellow leaf stripes, loss of plant vigour, and stunting of plants with yield losses of 40 to 100 per cent in wheat.Spores are wind dispersed in several cycles during the cropping season. Grasses and volunteer crop plants may generate a "green bridge" providing inoculum for the next crop cycle. Disease monitoring is important so timely action can be taken to limit the spread of the pathogen as well as build-up of inoculum. Disease management may include the use of resistant varieties, fungicide applications and control of pathogen reservoirs.New pathogen strains with increased virulence and additional fungicide resistances have been reported in recent years from wheat growing areas worldwide, including from India (ProMED-mail post 20090329.1216). However, no information is given above to suggest a new strain. Monitoring and resistance breeding programmes have been established in different regions for early detection of new rust strains and to attempt to stay ahead of pathogen evolution.MapsIndia:<http://www.mapsofindia.com/images2/india-map.jpg> and <http://healthmap.org/promed/p/37024>Jammu and Kashmir districts:<http://www.mapsofindia.com/maps/jammuandkashmir/jammuandkashmir-district.htm>PicturesStripe rust symptoms on wheat:<http://www.grdc.com.au/uploads/images/Stripe%20rust%20Colin%20Wellings%20ACRCP.JPG>,<http://www.plantmanagementnetwork.org/pub/php/brief/2005/stripe/image/wheat3.jpg>,and<http://www.uky.edu/Ag/GrainCrops/Images/7/7.11.jpg>Ryegrass with stripe rust:<http://www.science.oregonstate.edu/bpp/Plant_Clinic/images/ryegrass_stripe%20rust.jpg>and<http://plant-pest-advisory.rutgers.edu/wp-content/uploads/2013/09/photo-15-e1378922274640.jpg>LinksInformation on wheat stripe rust:<http://pnw-ag.wsu.edu/smallgrains/Stripe%20Rust.html>,<http://www.ars.usda.gov/Main/docs.htm?docid=9918&pf=1&cg_id=0>, and <http://www.dpi.nsw.gov.au/__data/assets/pdf_file/0006/158964/stripe-rust-in-wheat.pdf>Stripe rust management:<http://www.grdc.com.au/uploads/documents/striperustmgt.pdf> and <http://www.ipm.ucdavis.edu/PMG/r730100511.html>_P. striiformis_ life cycle:<http://www.nature.com/ncomms/2013/131023/ncomms3673/images/ncomms3673-f1.jpg>Stripe rust global tracking service:<http://rusttracker.cimmyt.org/?page_id=9>_P. striiformis_ taxonomy and synonyms:<http://www.indexfungorum.org/Names/NamesRecord.asp?RecordID=227064>and<http://www.speciesfungorum.org/Names/SynSpecies.asp?RecordID=227064>- Mod.DHA][See Also:2014----Stripe rust, cereals - France 20140616.2543141 Stripe rust, wheat - Spain: (CL) Warrior strain 20140523.2489629 Stripe rust, wheat - UK: Warrior strain, alert 20140122.2224928 Stripe rust, wheat - India: (PB, HR) 20140109.21626932013----Stripe rust, wheat - India: (PB) 20130118.15038582012----Stripe rust, wheat & triticale - Switzerland 20121004.1322743 Stem & stripe rusts, wheat: double resistance breeding20120831.1274190Stripe rust, triticale - Denmark: new strain susp 20120426.1114329 Leaf & stripe rusts, wheat - UK: new strains 20120208.1036727 Stripe rust, wheat - India: update 20120122.10179732011----Stripe rust & foot rot, wheat - USA, UK 20110713.2109 Stripe rust, wheat - India, UK: spread 20110404.1042 Stripe rust, wheat - UK: (England), Claire strain 20110304.0705 Fungal diseases, cereals - Australia: (eastern, south) alert20110218.0531Stripe rust, wheat - India: (PB) 20110211.04692010----Stripe rust, wheat - Lebanon 20101121.4214 Stripe rust, wheat - Turkey, Syria 20101021.3815 Stripe rust, wheat - Ethiopia 20100922.3420 Stripe rust, wheat - Africa, Asia: new strain 20100531.1803 Stripe rust, wheat - USA: (AR) new strains, alert 20100510.1522 Stripe rust, wheat - India, UK: alert 20100121.02342009----Rust diseases, wheat - UK, Pakistan 20090424.1543 Stripe rust, wheat - India: new strain 20090329.1216 Wheat rusts - Kenya, India, Australia 20090312.1019 Rust diseases, wheat, mustard - India: (JK) 20090305.0897 and additional items in the archives]More news from: ISID (International Society for Infectious Diseases)Website: http://www.isid.orgPublished: March 23, 2015The news item on this page is copyright by the organization where it originatedFair use notice
