Minimization of risk of pesticide residues in fruit production: certified methodology
Kocourek, František ; Falta, Vladan ; Stará, Jitka ; Holý, Kamil ; Horská, Tereza ; Vávra, Radek
The publication is intended for fruit growers who are included in integrated fruit production systems. The information and the recommendations presented in the matarial can help them to minimize risk of residues of of of pesticides on non-target organisms, mainly natural enemies. In addition, the minimizing of pesticide impact on human health is considered. All recommendations are in the accordance with requirements of legislation which will be in force from 2014 for IPM and also for convention regimes of fruit protection. The spray scheduling is based on the knowledge of pesticide pre-harvest period coupled with the information about their side effects on non-target organisms. Environmental behaviour of pesticide residues from the application to the harvest is desribed for each active ingredient allowed in the Czech Republic in apples and pears. These data enable to assess the action pre-harvest periods for the both low-residual and non-residual fruit production. Information about side effect on natural enemies of pests and other non-target organisms have been worked up for each active substance of pesticides allowed in fruits in the Czech Republic. This knowledge allows us to classify pesticides into three groups marked as a so called green, yellow and red list for IPM growing systems. The possibilites of the use of biological and biotechnological methods are outlined at the end of the publication.

Body Mass Index rate at man was usually in optimal range 20 - 25, despite this high percent of body fat, which is created by decreasing of muscle tissue and increasing of body fat. Discovered rates correspond with results comparising intake energy and nutrients with norm of need. All respondents had high intake of lipid and high intake proteins especially women. Intake of sacharide and dietary fiber was optimal. Be results show that respondents have low intake of vitamin D. When compared average intake vitamins and minerals with the norm of need. At minerals the increased intake selenium was found-approximately about fourteen percent from norm of need. At evaluation calcium and phosphorus was analysed opposite rate 1:1,2. Calcium intake is long time under norm of need in divide 20 - 40 %. The same conclusion is valid for magnesium. Magnesium intake is 15 - 30 % under norm of need. The results were consulted with a diet nurse who had information of higher creation of osteoporosis at seniors.

The last testing hypothes found out that krepiny drinking regime doesn{\crq}t depend on their sex. Thirty questionary were analyses twenty women and ten men took a part. Women were more interested in the questionary than man because they were more interested in questions of health food. A questionary included fourty-six questions which were divided into four parts. The first part is focused on information about respondents. The second part is about correct dribling regime and the fourth part of the questionary is focused on satisfaction on seniors in senior home. Part of thesis is recommendation on what concentrate attention in nutrition client senior home.
