Currently, there is no blossom thinning compound registered for the use in organic apple production; such are used in the conventional production to avoid alternate bearing. Beside calcium polysulphide (CaSx) and rape oil which are allowed in organic production as plant protection products, new organic compounds potentially suitable for organic blossom thinning were tested. After the time and quality study of damage, calcium polysulphide, NaCl and acetic acid were evaluated as adequate, not too aggressive compounds used for apple blossom thinning in organic production

Unchanged trans-caftaric acid was identified in blood plasm, brain, kidneys (but not in the liver) of rats 10 min and 20 min after the absorption from stomach. The study is important for the understanding of eventual biologic effects of this natural antioxidant in the organism of mammals, especially, since trans-caftaric acid is pretty much present in grapes and wine and in the pharmaceutical preparations from Echinacea (f. ex. in Immunal).

Laboratory studies have indicated that X. rivesi population present in Slovenia was capable of transferring viruses TRSV and ToRSV from one host plant to the other, i.e. it was determined for the first time that the European population X. rivesi might be able to transfer viruses. Two species of the genus Longidorus (L. juvenilis – first detection in Slovenia – and L. leptocephalus) were isolated from vineyard soil for the first time and in individual specimens of the species L. juvenilis the presence of the virus RBDV was established using molecular method.

Experiments were conducted on individual worker bees and on honeybee colony level. Different acaricides are used in honeybee colonies; oxalic acid and rotenone are considered as organic substances. Results show that oxalic acid or rotenone cause different level of larval mortality in a colony and also different level of treated bee mortality. Cell death occurs in the midgut after oxalic acid treatment. Toxicological and immunohistochemical methods are useful research methods in honeybee biology and pathology.

It was found out that maize grain texture had a crucial effect on the digestion and metabolism of energy and protein in ruminants. The findings offer direct solutions in the sense of better utilization of energy and protein and lesser emissions of greenhouse gases and ammonium in the breeding of ruminants.
