All the mentioned species have a high reproductive potential, which in warm and dry conditions leads to a rapid growth of populations. The period of activity and feeding of mites begins in spring and lasts until autumn, and the most pronounced symptoms are noticeable during the summer months. Nutrition and leaf tissue damages cause chlorosis and/or necrosis, photosynthetic disorders, increased transpiration, defoliation, fruits remain small, lose quality and decline, so yield losses can be extremely large.","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":"77014805","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}

Ivanović","doi":"10.5937/biljlek2203195i","DOIUrl":"https://doi.org/10.5937/biljlek2203195i","url":null,"abstract":"Agriculture is the world's second largest source of employment, often involving long hours and heavy work in challenging climates and harsh conditions. The continued development of sustainable intensive agriculture is essential to maintain the quality and quantity of agricultural products for consumers, particularly with the scarcity of natural resources, climate change, a growing world population and the physical limitation of productive agricultural land. On farm best management practices (BMPs) during transport, storage and use of crop protection products (CPP) help to avoid the contamination of operators, soil and water bodies. Also, the correct disposal of empty CPP containers and remnants from spraying is crucial to avoid point source contamination of water bodies. BMPs include wearing appropriate personal protective equipment to prevent direct contact with crop protection products. When BMPs are in place for handling and using PPPs and product spills are managed properly, the risk of contamination both to humans and the environment will be reduced significantly. Farmers around the world should be aware that land and water management are critical for agriculture and ecosystems. On-farm water management optimizes water use for crops and other farm operations. Spray drift, drain flow, run off and leaching from fields may cause contamination of surface and ground water. The adoption of best management practices, such as field margins, optimized irrigation systems and best in class application technology, will help to prevent such contamination as well as improve agricultural productivity. Significant surface water contamination can also occur as a result of improper filling and cleaning of spray equipment. It is simple and easy to prevent by using separated based systems to collect this and other waste water. In separation based systems, waste water is put in a container. Crop protection products are then physically separated from the water, e.g. by evaporating the water into the atmosphere with the help of the wind and sun, which leaves the residues of crop protection products in the container.","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":"82487960","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 is estimated that apple blue mold causes multimillion-dollar losses annually. It can affect any apple variety, due to mechanical damage, inadequate protection or storage conditions. Various Penicillium species can cause apple blue mold, but the most significant is Penicillium expansum. Besides economic losses, Penicillium species cause a threat to human health, due to mycotoxin production. To prevent the apple blue mold, the application of preventive measures is necessary, such as careful handling of fruits during harvest, and maintaining hygienic conditions in the storage. Most of the current preharvest fungicides are applied days before harvest and may not be effective in combating this disease, since Penicillium infections usually occur after the harvest. Therefore, post harvest fungicide applications remain the most effective chemical way to control blue mold. In addition to chemical protection, efforts are made to provide efficient biological solutions for the control of this disease. The incidence of apple blue mold is significantly reduced since controlled atmosphere storages are in use, but it still remains the most important post harvest disease of apple fruits.","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":"80663640","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}

Keserović","doi":"10.5937/biljlek2206411m","DOIUrl":"https://doi.org/10.5937/biljlek2206411m","url":null,"abstract":"Apple is a temperate fruit from the Rosacea family. It is of great importance in fruit growing in the world, considering that it is the second fruit tree in terms of volume of production. In developed countries, apple production is at a high technological level, so the volume of production does not change or even increases, regardless of the reduction of the area under this fruit species. Intensifi cation of production is achieved primarily by increasing the number of trees per unit area and, accordingly, by reducing the dimensions of the crown. With the introduction of low-growing rootstocks and small-sized cultivation forms, apple production experienced a major transformation in the world, but also in Serbia. The volume of production and the area under apples in Serbia are constantly increasing. One of the reasons is the good agro-ecological conditions that prevail in Serbia, as well as the apple's adaptability, especially its relative resistance to low temperatures and spring frosts. Planting material for high-intensity apple plantations includes seedlings with premature twigs, so-called \"Knip\" seedlings, which produce the fi rst crop already in the year of planting, and can produce a full crop in the fourth year. In order to make the most of the potential of these seedlings, and to secure investments, the standard technology of raising seedlings implies the use of anti-hail nets and irrigation systems from the moment of planting. Also, care is taken of proper soil maintenance, fertilization, and quality and regular fertility are ensured by the use of bioregulators. Today, the leading apple varieties in Serbia are the same as in the leading apple-producing countries, while the M 9 substrate is almost the only one used in modern dense plantings. The apple is currently the leading fruit species in Serbia for the production of fresh fruit, and this position will not change for a long time.","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":"80010570","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}
