White rot (Sclerotinia sclerotiorum) is a fungal disease that affects many crops. Usually, plant protection products are used to control it. However, their use is often undesirable due to numerous side effects. An alternative to this are non-chemical methods of protection. These are divided into agrotechnical and low-risk fungicides. Agrotechnical methods are mostly already well established, while low-risk crop protection is only partially in use in Slovenia. The low-risk crop protection agents are divided into biotic, biochemicals, minerals and basic agents. Biological control includes suppression by living agents or their active ingredients. Their effect on white rot can be indirect by promoting resistance or directly by parasitism, space and food deprivation. Biochemicals, minerals and basic agents are substances of plant or inorganic origin that have an anti-fungal. This thesis presents white rot and its possible alternatives to chemical control before and after harvest.
