Pest management in flower production on the family farm Franjo Zvijerac in 2023

Cilj rada je bio istražiti prisutnost i brojnost štetnika cvijeća na OPG-u Franjo Zvijerac u Ivankovu. U okviru provedenog istraživanja analizirano je šest cvjetnih vrsta (krizantema, pelargonija, surfinija, begonija, hortenzija i vinka) koje se proizvode na navedenom OPG-u. Populacija štetnika na cvjetnim vrstama praćena je tijekom razdoblja od dva mjeseca (početak lipnja do početka kolovoza) vizualnim pregledima biljaka te uz pomoć žutih i plavih ljepljivih ploča. Vizualnim pregledima utvrđena je prisutnost samo lisnih uši, na svim cvjetnim vrstama, izuzev vinke. Lisne uši pojavljivale su se periodično, u nekoliko navrata tijekom razdoblja istraživanja, i to pojedinačno ili u obliku vrlo malih kolonija. Samo u jednom slučaju, kod begonije, utvrđeno je postojanje nekoliko malih kolonija lisnih uši. Determinacijom kukaca na ljepljivim pločama utvrđena je najveća prisutnost reda Diptera i Hymenoptera. U plasteniku nije utvrđena prisutnost većeg broja štetnika zbog toga što se planski provode preventivni tretmani insekticidima, uz poštivanje stručnih preporuka za primjenu sredstava za zaštitu cvijeća od štetnika.The aim of the work was to investigate the protection of flowers from pests at the OPG Franjo Zvijerac in Ivankovo. Within the framework of the research conducted, six flower species (chrysanthemum, pelargonium, surfinia, begonia, hydrangea and vinca) produced at the mentioned OPG were analyzed. Their morphological characteristics, the basics of cultivation and the most important pests that attack them are indicated. The population of pests on flower species was monitored during a period of two months (beginning of June to beginning of August) by visual inspection of the plants and with the help of yellow and blue adhesive panels that were placed near the investigated flower species. Visual inspections revealed the presence of only one type of pest, aphids, on all flower species, with the exception of vinca. Aphids appeared periodically, on several occasions during the study period, individually or in the form of very small colonies. Only in one case, with begonia, was the existence of several small colonies of aphids found. The determination of insects on the adhesive plates revealed the highest presence of the order Diptera and order Hymenoptera. In the greenhouse, the presence of a large number of pests was not determined due to the fact that preventive treatments with insecticides are carried out in a planned manner, with the observance of expert recommendations for the use of means to protect flowers from pests
