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.
