RESEARCH ON STOLBUR OF PEPPER (CAPSICUM ANNUUM L.) CULTIVATED UNDER THE CONDITIONS OF ORGANIC FARMING

Veselka Vlahova

Abstract


In Bulgaria stolbur is a disease of economic significance that affects pepper, eggplant, tomatoes, and potatoes. Stolbur is referred to the transmission diseases, i.e. the agent is being transferred via vector, namely cicada Hyalesthes obsoletus in this specific case. This research aims at following the stolbur disease of pepper of the variety of Sofiiska Kapiya. The experiment took place in 2010 and in 2011 on the experimental fields of the Agroecological Centre at the Agricultural University- Plovdiv. The occurence of Hyalesthes obsoletus was determined via visual observations of flower sticky traps (yellow, blue, and white). Route investigations were carried out for the purpose of tracking the symptoms of the disease. Reinforced migration of cicadas was established during the second ten days of July. It was established that the larger number of cicadas were reported for the yellow sticky traps, which may be recommended for practical application as a successful fight against cicada and limitation of its flight.
