Abstract:
Nowadays, worldwide it is realized that the problems linked with the ecological crisis at a great degree are conditioned by intensive and sometimes abusive application of pesticides (L. Ehler, D. Bottrell, 2000; I. Popuşoi , L. Voloşciuc, 2004). Profound ecosystem investigations (E. Boller, C. Malovolta, E. Jorg, 1997; M. Berca, 2000), have demonstrated that the profound interaction between plants protection and environment can be stopped only in the case of agricultural development as an organism, which has as a model the natural ecosystems (M. Berca, 2000, L. Volosciuc, 2007)
