The new, more reliable system of calculation the dose of thinning agents used in apple orchards was proposed. The old system was unreliable with no consistent efficiency, so the new system concerning the volume of crowns was introduced for calculation the proper amount of thinning agent per hectare of orchard. The new system is more efficient and ecologically more acceptable.

Fruits and vegetables are rich in flavonoids and epidemiological data show that they confer protection against many chronic diseases. However, flavonoid bioavailability is reported to be low in mammals and the molecular mechanisms of actions are poorly known. The review focuses on membrane transport of flavonoids, a critical determinant of their bioavailability.

Pesticide residues and microbiological quality of 25 bottled wines was determined. Furthermore, the effect of bentonite and the combined fining agent on the concentration of boscalid in wine was tested. Nine pesticide residues were determined in the samples. More than 50% of wines belonged to the category of wines with only up to two pesticide residues. The most frequently determined pesticide in wines was boscalid (76% of samples) followed by fenhexamid (44%). The combined fining agent was more efficient in lowering the concentration of boscalid in wine if compared with bentonite.

Raspberry bushy dwarf virus (RBDV) was found in grapevine in Slovenia in 2003. This was the first reported natural infection of non-Rubus host with RBDV. The grapevine isolate was characterized serologically, its experimental host range was investigated and most of RNA 2 was sequenced. The grapevine isolate is clearely different from slovenian red raspberry isolate. Additionaly, the presence of RBDV in nematodes Longidorus juvenilis was detected what indicates a possible role of nematodes in RBDV transmission. The possibility of nematode transmission of RBSV was not reported before.

Honey bee (Apis mellifera carnica) colonies were placed in two apple orchards treated with the insecticides diazinon and thiacloprid and the fungicide difenoconazole. Pollen and bee bread were collected from combs inside the hives. The residue of diazinon in pollen loads 10 days after orchard treatment was 0.09 mg/kg, and the same amount of residue was found in bee bread 16 days after treatment. In pollen loads 6 days after application 0.03 mg/kg of thiacloprid residues and 0.01 mg/kg of difenoconazole were found on the first day after application.
