In the modern society of today, consuming natural products is not a hobby anymore and it is a necessity for us regarding health. The first factors of disease are owed to unhealthy food and we cannot have a healthy food and a healthy organism if we do not remove from our food system the negative effects possessed by unhealthy food, even if it is not the cheapest option. From the products consumed by people, a very important role for producing the necessary energy for the organism is given to vegetables. Thus, we aimed the study of using decoctions obtained from the Aristolochia Clematitis plants which can be found in the spontaneous flora of Romania, unpretentious regarding the soil and which can combat one of the most frequent pests met in cabbage cultures: cabbage aphis (Brevicoryne brassicae L.), cabbage fly (Delia brassicae), cabbage butterfly (Pieris brassicae). The elimination of contact insecticides and chemical substances and obtaining healthier products are several purposes by using these methods. The obtained decoctions were made by combining three types of plant mixes in order to identify which component part is richer in aristolochic acid and which decoction gives better results for the combat of insects and to make a better comparison between them related to obtained results. There were taken soil samples from the six cultivars between planting cabbage seedlings for a better documentation. After the observations made on the whole period, the best results were obtained at cultivars 1, 3, 5, 6 where cabbage plants were treated with decoction obtained from the roots and where the whole plant combined with soap solution was used, followed by cultivars 2 and 4 where there was not used Aristolochia Clematitis plants. Because the results obtained were satisfied without using contact insecticides, a larger investigation of these decoctions follows using only Aristolochia Clematitis plants or in combinations with other plants which have very good results for ecological control of diseases and pests from vegetable cultures.
