Abstract

In the context of global climate change, Romania is also seeing changes related mainly to the annual average temperature increase of about 1.6 ° C, the increase in summer temperatures (July and August), which led to changes in the biology of the diseases and pests. Combating crop pests is done through several methods: physical-mechanical (thermal disinfections of seeds), chemical (using pesticides), agro-technical (through soil works, including weeds) but also biological (by using natural and of antagonistic organisms). Bioproducts are biological means made on the basis of natural compounds (plant extracts) with a complex action on crop plants, biopreparations that have been shown to be stimulants of vegetative growth. Application of bioproducts is done by treatments, which are either seed treatments or treatments in vegetation (sprays with different volumes of liquid). In 2016 at CCDCPN Dăbuleni, were tested the basil oil for cowpea seeds, mint oil for peanut seeds, santal oil  for green melon seeds to germination and root growth.
