Abstract only
Cereals pest and diseases can be a reason for significant losses of yield in Tajikistan. As cereal crops, especially wheat plays a crucial role on achieving food security, thorough investigations of all constraints are important. Thus, with technical support of FAO-SEC we are conducting surveillance of pests and diseases in main wheat growing areas of Tajikistan starting from 2012. During the 2012 surveillance main foliar diseases, yellow rust (caused by Puccinia striiformis, f.sp. tritici), leaf rust (P. recondita, f.sp. tritici) and stem rust (P. graminis, f.sp.tritici) were seen very rarely, with very low incidence only in few fields. Compare to previous year in 2013 local epidemics of yellow rust was observed mainly in Hisor valley. Other parts of the country were not highly affected by the diseases, althoLgh major wheat varieties were affected by disease. Common bunt (Tilletia laevis) and loose smut (Ustilago spp.) found to be serious mostly in rain fed areas. During 2012 insect damage was found to be more serious and significant than 2013, Insect pests, such as cereal leaf beetle (Oulema melanopus), sunn pest (Eurygaster integriceps), aphids (Schizaphis graminum, Diuraphis noxia) and sawfly (Cephus cinctus) are causing most Insect damages. Weeds are spread throughout all the cereals fields, this problems need a serious attention, especially in the seed crops. Most spread weed plants of cereal crops are Convolvulus arvensis, Avena fatua, Gallium apparene, Sinapis arvensis, Chenopodium album etc. Within the project 38 seed samples of released and widely grown wheat varieties were submitted for testing to resistance to main diseases in hot spots/or under artificial conditions to Turkey, Kenya, USA and Mexico (CIMMYT).
