Bakterioze tikava

Abstract

Production of cucurbits has a long tradition worldwide. Cucumber, watermelon and melon production is very important for many producers in some parts of Serbia. These crops are especially susceptible to phytopathogenic bacteria which can cause substantial losses in years with favorable weather conditions. In this paper major bacterial diseases of cucurbits are described, such as bacterial fruit blotch caused by Acidovorax citrulli, angular leaf spot caused by Pseudomonas syringae pv. lachrymans, bacterial spot caused by Xanthomonas campestris, bacterial wilt caused by Erwinia tracheiphila, cucurbit yellow wine disease caused by Serratia marcescens, bacterial leaf spot, caused by Pseudomonas syringae pv. syringae, inducing bacterial soft rot caused by Pectobacterium species.Biljke familije Cucurbitaceae imaju dugu tradiciju proizvodnje širom sveta. U pojedinim krajevima Srbije, naročito severnim, proizvodnja krastavca, lubenice i dinje predstavlja primarno zanimanje mnogih poljoprivrednih gazdinstava. Pojava bakterioza u godinama sa uslovima koji pogoduju nastanku infekcije, može značajno ugroziti proizvodnju ovih biljaka. U ovom radu predstavljena su najznačajnija bakteriozna oboljenja biljaka familije Cucurbitaceae, među kojima su: bakteriozna mrljavost plodova lubenice, čiji je prouzrokovač Acidovorax citrulli, uglasta pegavost lišća krastavca, prouzrokovana bakterijom Pseudomonas syringae pv. lachrymans; bakteriozna uvelost krastavca prouzrokovana vrstom Erwinia tracheiphila; bakteriozna pegavost koju prouzrokuje Xanthomonas cucurbitae; potom žutilo vreža, čiji je prouzrokovač Serratia marcescens; zatim bakteriozna lisna pegavost prouzrokovana Pseudomonas syringae pv. syringae; kao i bakteriozna vlažna trulež prouzrokovana vrstama roda Pectobacterium
