Risk management of mycotoxins begins in the field

Kukuruz i pšenica najvažnije su naše žitarice. One u najvećem postotku sudjeluju u nas u ishrani ljudi i domaćih životinja. Kukuruz i pšenica su podložne napadu toksinogenih gljivica iz rodova Fusarium, Penicillium i Aspergillus. Nabrojene su Fusarium vrste nađene na zrnu pšenice u Hrvatskoj. Navedena je učestalost Fusarium vrsta u polju na kukuruzu i pšenici i važni mikotoksini koje oni proizvode. Kratko su opisani simptomi učestalijih Fusarium vrsta na kukuruzu i pšenici u polju. Nabrojene su Penillicium vrste koji su nađene na zrnu kukuruza u raznim tipovima skladišta u Hrvatskoj. Opisani su simptomi na zrnu kukuruza i navedeni toksikološki važniji mikotoksini Penicillium vrsta. Navedeni su simptomi koje može izazvati Aspergillus flavus na zrnu kukuruza. Preporučene su preventivne mjere koje se trebaju provesti u polju da bi se smanjila prisutnost toksinogenih gljiva na kukuruzu i pšenici.Corn and wheat are the most important cereal crops in Croatia. They participate with the highest percentage in diet of humans and domestic animals. Corn and wheat are subject to attack by toxigenic fungi of genera Fusarium, Penicillium and Aspergillus. Fusarium species found on wheat grain in Croatia are listed. Incidence of Fusarium species on corn and wheat is specified, as well as important mycotoxins they produce. Symptoms of frequent Fusarium species on corn and wheat in the field are briefly described. Penillicium species that are found in corn grain in different types of storage facilities in Croatia are listed. Symptoms in the grain are described and more important toxigenic species of Penicillium mycotoxins are stated. Symptoms caused by Aspergillus flavus on corn in field are presented. Recommendations for preventative measures for implementation in the field in order to minimize the presence of toxigenic fungi on corn and wheat are given

DISTRIBUTION OF BLACK ROT [Phyllosticta ampelicida (Engelm.) Aa] OF GRAPEVINE IN CROATIA

Članak donosi podatke o rasprostranjenosti crne truleži bobe [Phyllosticta ampelicida (Engelm.) Aa] na vinovoj lozi u Hrvatskoj. Uzročnik je prvi put opisan 1927. godine u okolici Splita. Bolest se 1934. godine pojavila na otoku Krku uzrokujući vrlo visoke gubitke u prinosu. Na tom području parazit je i danas prisutan, iako to ne uzrokuje velike štete zbog zaštite koja se provodi protiv dugih bolesti, napose protiv crne pjegavosti. Osim otoka Krka, bolest se također proširila na obližnjem otoku Cresu i na kontinentalnom području u okolici Rijeke, Sušaka, Crikvenice i Novog Vinodolskog. Bolest je povremeno je zabilježena na otoku Korčuli i u zaleđu Dubrovnika. Opisani su simptomi, biologija te dane preporuke za zaštitu.The article gives and overview on grapevine black rot disease [Phyllosticta ampelicida (Engelm.) Aa] in Croatia. Black rot was described in Croatia for the first time in 1927 in Split area. In the year 1934 it spread in vineyards on the island of Krk, causing very high yield losses. The parasite is still present in this area today, although it does not cause much damage, mostly because of chemical control of other grapevine diseases. Beside the island Krk, the disease has also spread to the nearby island Cres and to the continental surroundings of Rijeka, Sušak, Crikvenica and Novi Vinodolski. Black rot has been occasionally recorded on the island of Korčula and in the hinterland of Dubrovnik. Symptoms and biology are described in the article, and recommendations for black rot control are given
