Protection of the organically produced potato crop against the Colorado beetle
As an alternative to synthetic insecticides, some of the current combat concepts (especially in the field of organic culture) refer to the use of insecticides extracted from different plants and microorganisms.
The purpose of the research in this work was to test some alternatives to the chemical method by using some metabolic extracts from plants and some bioinsecticides.
The effectiveness of metabolic extracts when performing two treatments was over 80% for the extract obtained from Athyrium filix-femina, followed by the combination obtained from Tanacetum vulgare + Arthemisia absinthium, with over 70% efficacy.
Even if these insecticides obtained from plants are not very effective, some of them induce the inhibition of feeding because the damage to the leaf surface is only a very small percentage (up to 10%).
