Drechs, the agent of tan spot, is an economically important pathogen of wheat. It causes grain quality distortion and yield losses up to 53%. Ptr is a necrotrophic pathogen and produces three types of necrotrophic effectors (NEs) (Ptr ToxA, Ptr ToxB and Ptr ToxC) that induce necrosis and chlorosis. The genetic basis of the Ptr-host interaction also includes genes that provide race-nonspecific resistance. In 2022, the percentage of genotypes infected with Ptr in the collections of \"disease nurseries\" ranged from 11.4% to 94.3%. The lowest number of infected genotypes (11.4%) was recorded in breeding pro-grams for resistance to prevalent pathogens. A low number of genotypes infected with Ptr was also found in the collection of wild relatives (18.4%), while the highest percentage of genotypes susceptible to Ptr was found in varieties originating from Kazakhstan (94.4%). Disease index of Ptr ranged from a trace level up to 50% or more. The length of the Ptr conidia ranged from 73.4 mm to 107.2 mm. Conidia width ranged from 15.5 to 22.8 mm. The results of this study indicated on genotypes that could be used as sources of resistance to Ptr, and also could be introduce in further studies of the mechanisms that provide resistance for Ptr.","PeriodicalId":8829,"journal":{"name":"Biljni lekar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81023319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It causes serious damage to numerous vegetable and ornamental plants by feeding. Its economic importance is even higher because it transmits more than 400 virus species. Bemisia tabaci was found for the first time in Montenegro in May 2008 on Hibiscus sp. in area of the city of Podgorica. The first detection on vegetables was in September 2011 on melon (Cucumis melo L.) in an open field near city of Ulcinj. After the fi rst detection on vegetables, monitoring of B. tabaci was conducted in next five years (2012-2016) on localities in southern part of Montenegro (Ulcinj, Bar, Budva, Tivat, Herceg Novi, Podgorica) where the main vegetable production is placed. Visual inspections were carried out several times during the growing season from the end of June to the first half of October, on different vegetable plants. The results of the five-year monitoring showed the presence of B. tabaci in the area of Ulcinj, Bar, Budva, Tivat and Podgorica. No presence was detected in area of Herceg Novi. It was also established that the population density varied depending on the host plant and locality. B. tabaci was found on eight vegetables belonging to two botanical families: melon, cucumber, zucchini, pumpkin and watermelon (Cucurbitaceae), eggplant, tomato and pepper (Solanaceae). The melon was found as the most preferable host, followed by cucumber and eggplant. The complete development of B. tabaci was successfully completed on melon, cu cumber and eggplant.","PeriodicalId":8829,"journal":{"name":"Biljni lekar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86719643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research was to obtain answers to selected questions on the basis of which the training and behavior of users could be assessed, ie whether the application of PPPs is in accordance with the regulations for users supplied with PPPs in smaller stores. Thanks to the initiative and support of the Ana and Vlade Divac Foundation, a survey of PPP users on knowledge of regulations and behavior related to the use of PPP was organized on the territory of the Republic of Serbia. The survey was preceded by training of interviewers, and the questionnaire was designed to examine the attitudes of respondents on behavior in the selection, application, storage, use of personal protective equipment, knowledge of regulations in this area, packaging waste management and other selected important aspects related to PPPs use. Interviewers conducted the survey from 7-17. May 2021, during which 1030 farmers were interviewed in a random and representative sample, in 116 municipalities and 227 agricultural pharmacies. The answers to the questions from the questionnaire were grouped into logical units, analyzed and presented for the territory of the Republic of Serbia, the segmentation of the results of the total sample by regions, gender, age and level of education was done. The survey mostly covered farms with an arable land size of up to 10 ha (71.8% for the whole of Serbia), and the most represented were respondents older than 50 years (58.7%), with completed high school (74.7%). Small shops of agricultural inputs are the main supplier of PPPs (96.2%), and the majority of respondents make the decision in choosing PPPs (83.8%). Before buying PPP, 91.5% of respondents consult with experts, and the most useful advice for choosing PPP is received from sellers at the point of sale (67.4%), advisors from advisory services (18.9%), representatives of PPP manufacturers (7.5%) and at least via the internet, TV and press (2.3%). The majority of respondents apply PPPs according to the label (85.7%), and records on the types and quantities of PPPs stored and used are kept by 75.7% of respondents. A large percentage of PPP users do not use any personal protective equipment (4.6%), while only 21.3% of respondents use complete personal protective equipment. About 6% of respondents bought illegal PPPs, and the main reasons were higher trust (56.6%), better price (25.3%) and recommendations (13.1%). Of the total number of respondents, only 15.6% store PPPs in a special room for this purpose, as many as 24.2% of respondents do not use the rinsing of PPPs containers. The behavior related to the management of packaging waste from PPPs is worrying, with 50% of respondents disposing of packaging in municipal waste, 37.4% destroying it by burning, 3.3% disposing of it in th","PeriodicalId":8829,"journal":{"name":"Biljni lekar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87334779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper describes the characteristic symptoms of the 25 most important diseases of stored apple fruits caused by various pathogens, as well as an overview of other less signifi cant pathogens that can appear on apple fruits during their storage.

Altogether, five frequency peaks were recorded from June to October. Recorded peaks corresponded to DD values of 245, 457, 593, 660 and 787, respectively. The highest peak corresponded to DD value of 593. In order to get a broader picture of the appearance, DD were also calculated for 2017, 2018 and 2019.
