Slugs can cause extensive damage in agricultural plant production. Due to the restriction of the use of pesticides such as metaldehyde (limacid), it became necessary to search for new, environmentally safe methods for the control of slugs. In our experiment, the use of parasitic nematodes Phasmarhabditis hermaphrodita on which the commercial preparation Phasmarhabditis-System (Biobest, Belgium) is based, has proved to be a successful method of biotic control of slugs.

COBISS.SI-ID: 5573224Researchers from the Department of Plant Protection of the Agricultural Institute of Slovenia successfully tested several preparations for the biotic control of salad white rot. The results show that a biotic product based on Coniothyrium minitans can achieve statistically the same efficiency as with the established method of chemical protection. At the same time, this method also reduces the stock of dormant sclerotia in the soil, which is not achieved with chemical fungicides, and the effect of use can be noticeable in the following cultures on the treated plot. With repeated soil treatments, we can also return the soil heavily loaded with sclerotia of white rot to the state when the production of vegetables will not be compromised.

COBISS.SI-ID: 5707112Researchers from the IHPS have successfully tested different methods with low risk against cabbage flea beetles. Although the minimum damage to the cabbage was achieved with the standard insecticide Karate Zeon 5 CS, alternatives should be sought, as it is likely that the product will lose its authorization to use in the following years. A positive impact on the reduction in the flea population was achieved using wood ash and CutiSan, which could be a good alternative to chemical preparations in the future. Laser plus has also been shown to be very effective, but it is now registered for use on cabbage only for the control of floral thrips and Agrotis spp. moths. In view of the efficacy found, it would be wise to extend the use of the Laser Plus insecticide for Phyllotreta spp. control in cabbage. In the future, more attention will have to be paid to the various combinations of biostimulants that can successfully reduce the damage from flea beetles in cabbage in a way that promotes the growth and general resistance of plants.
