Mikoze krmnog bilja čiji se prouzrokovao prenose semenom i nečistoćama uz seme
Mycosis in forage crops transmitted by seed and impurities
Univerzitet u Novom Sadu, Poljoprivredni fakultet
Sažetak
Seme krmnih vrsta trava i leguminoza naseljavaju mnogi saprofitni i patogeni mikroorganizmi. Oni proizrokuju oboljenja semena i klijanaca i obezbedjuju inokulum za infekcije u kasnijim fenofazama. Daje se pregled najvažnijih mikroorganizama koji se prenose semenom i primesama, a detaljnije su opisani patogeni lucerke, detelina, sirka, krmnih trava. Problemi zaraženosti semena mogu se rešavati primenom fungicida i dezinfektanata, no jedini pravi isplativi način je selekcija na otpornost.
Abstract
Many microorganisms could infect forage grasses and forage legumes seed. The seed is the source of infective inoculum for seed, seedlings, young and mature plants infection. Most important seed transmitted pathogens of alfalfa, clovers, sorghum and forage grasses are described. Pathogens of related to forage plant species which are either common to field, industrial or vegetable crops are omitted, as being given elsewhere in corresponding chapters of this issue. The problems of seed infection could be minimized by sanitary, environmental, cultural and by use of seed dressing chemicals fungicides application in field, but the only proper, long lasting and fiseable way is the use of resistant cultivar.
