Strawberry diseases on family farm Grgošević

Na obiteljskom gospodarstvu kao glavna kultura uzgaja se jagoda. Jagoda je podložna razvoju gljivičnih oboljenja te stoga zahtjeva pravovremenu zaštitu u vidu agrotehničkih mjera, a prema potrebi i primjenu sredstava za zaštitu bilja. Cilj završnog rada je bio utvrditi pojavu bolesti koje su se javile na obiteljskom gospodarstvu u 2020. godine, a na temelju simptoma i morfologije parazita te prikaz programa zaštite koji se koristi na OPG-u.Strawberries are grown as the main crop on the family farm. Strawberry is susceptible to the development of fungal diseases and therefore requires timely protection using agrotechnical measures and, if necessary, and pesticides. The aim of the final work was to determine the occurrence of diseases that occurred on the family farm in 2020, based on the symptoms and morphology of the parasite and presentation of protection measures

Potential of plant extracts against species of the Pentatomidae family

Zelena štitasta stjenica, (Nezara viridula L., 1758) invazivna je vrsta stjenice uvrštena u porodicu fitofagnih stjenica Pentatomidae. Cilj istraživanja bio je utvrditi potencijal biljnih ekstrakata ambrozije (Ambrosia artemisiifolia L.) i običnog vratića (Tanacetum vulgare L.) za suzbijanje ličinki i odraslih stadija stjenica. Istraživanje je provedeno u laboratorijskim uvjetima u četiri tretmana: vodeni ekstrakt ambrozije, vodeni ekstrakt običnog vratića u koncentracijama 5% i 10%, kemijski insekticid Laser i voda kao kontrola. Pokus je bio postavljen u četiri ponavljanja, pri čemu je svako ponavljanje sadržavalo 10 jedinki. Mortalitet je zabilježen nakon 24, 48, 72 i 96h. Kod vodenog ekstrakta ambrozije utvrđena je učinkovitost od 23,52% na ličinkama dok je kod tretmana običnog vratića (5%) utvrđena učinkovitost 16,21% na odraslim jedinkama. Tretman s običnim vratićem u koncentraciji 10% pokazao je stimulativno djelovanje na preživljavanje odraslih i ličinki. Potrebno je provesti dodatna istraživanja s više različitih koncentracija kako bi se ova teza mogla potvrditi.The green shield bug, (Nezara viridula L., 1758) is an invasive phytophagus insect species and belongs to the Pentatomidae family. The objective of this study was to determine the potential of plant extracts of ambrosia (Ambrosia artemisiifolia L.) and common tancy (Tanacetum vulgare L.) to control the larvae and adult stages of N. viridula. The experiment was conducted under controlled conditions in four treatments: aqueous extracts of ambrosia (10%) and common tancy (5% and 10%), chemical insecticide Laser and water as a control. The experiment was set up in four replicates, where each replicate contained 10 individuals. Mortality was recorded after 24, 48, 72 and 96 hours. Ambrosia had a 23.52% effectiveness at the larval stage, while the common tansy (5%) showed only 16.21% effectiveness on adulds. Survival in both adults and larvae was stimulated by the common tancy treatment with higher concentration. Complementary research with several different concentrations is required to confirm this theory
