Production of fruit and vine planting material in 2017 in Croatia

Proizvodnju voćnog i loznog poljoprivrednog sadnog materijala u 2017. godini za stručni nadzor Hrvatskom centru za poljoprivredu, hranu i selo, Zavodu za sjemenarstvo i rasadaničarstvo prijavilo je 60 rasadnika voćnih sadnica i 15 rasadnika loznih cijepova. Ukupno je prijavljeno 4.394.442 voćnih sadnica i 3.057.226 loznih cijepova, što predstavlja blagi porast količine proizvodnje voćnog i loznog sadnog materijala. Ukupno su u proizvodnji 31 voćna vrsta i 69 sorti vinove loze. U prijavljenoj strukturi proizvodnje voćnih sadnica najviše su zastupljene jabuke sa 36,01 % i lijeska sa 20,11 %, a zatim masline (6,42 %), kruške (5,76 %), višnje (4,68 %), trešnje (3,82 %), šljive (3,65 %), itd. Od ukupne prijavljene količine voćnih sadnica 15 % su sadnice certificirane kategorije, dok je od ukupne prijavljene količine loznih cijepova certificiranih 54 %.In the 2017 60 fruit and 15 grape vine nurseries have applied for official inspection of nursery production to Croatian Centre for Agriculture, Food and Rural Affairs, Institute for Seeds and Seedlings. 4.394.442 of fruit plants (33 species), and 3.057.226 of grape vine plants (69 varieties) have entered the sistem of official inspection which represents a minor increasing trend in fruit and vine planting material production. The largest part in production of fruit planting material are apples (36.01 % of total fruit species), followed by hazelnuts (20.11 %), olives (6.42 %), pears (5.76 %), cherries (4.68 %), sweet cherries (3.82 %), plums (3.65 %), etc. 15 % of the fruit plants and 54 % of grape vine plants in the system of official inspection of nursery control were category “certified”

Production of fruit and vine seedlings material in the Republic of Croatia

U okviru Centra za sjemenarstvo i rasadničarstvo (nekada Zavod) pri Hrvatskoj agenciji za poljoprivredu i hranu kojeg je osnovala Vlada Republike Hrvatske 1998. godine kao nacionalno ovlašteno tijelo za nadzor i provođenje poslova iz područja sjemenarstva i rasadničarstva, nalazi se i Odjel za rasadničarstvo. Od početka svog djelovanja Odjel za rasadničarstvo provodi stručni nadzor i nadzor pod stručnom kontrolom nad proizvodnjom voćnog i loznog sadnog materijala, vodi evidenciju na nacionalnoj razini o matičnim stablima i trsovima za proizvodnju voćnog i loznog reprodukcijskog materijala te količinama proizvedenih voćnih sadnica i loznih cijepova prema vrstama, sortama, podlogama, kategorijama. Područje nadzora proizvodnje sadnog materijala i izdavanje certifikata provodi se prema Zakonu u sjemenu, sadnom materijalu i priznavanju sorti poljoprivrednog bilja (NN 110/21) i pratećim podzakonskim aktima.The Center (before the Institute) for Seed and Seedlings at the Croatian Agency for Agriculture and Food, was established in 1998 by the Government of the Republic of Croatia as a national competent authority for seed and seedlings certification. Since the beginning of its activity Department for planting material has been carrying out official certification and certification under official supervision of fruit and vine planting material. Department for planting material has been keeping records of fruit and vine mother plants and the quantities of fruit seedlings and vine grafts produced at the national level. Those records are kept according to species, varieties, rootstocks, categories of planting materiala. Official certification including certification under official supervision is carried out according to Official Controls Regulations (The Law on Seeds, Planting Material and Registration of Agricultural Plant Varieties,Official Gazette 110/21and its accompanying by-laws

Komparativni učinak različitih insekticida i kaolina na smanjenu brojnost populacije Cacopsylla pyri L.

Cacopsylla pyri L. (Hemiptera: Psyllidae) is one of the most serious economic pear pests in Eastern Croatia. Previous methods of pear control in the Republic of Croatia have led to the development of an insect population resistan to certain active ingredients. The objectives of this two-year study were to determine the optimal number of treatments for psylla control based on the monitoring of pest life cycle and to determine the effectiveness of processed kaolin in controlling the pear psylla in comparison with other chemical insecticides in four different treatments (T1. IPM-integrated protection program – diflubenzuron, spirotetramat, abamectin, acetamprid; T2. acrinatrin + abamectin, T3. kaolin clay, T4. control treatment). The research was conducted in 2017 and 2018 in a six-year-old experimental pear orchard on three varieties (Williams, Conference, and Abate Fetel). Monitoring of the pest population and its development was performed by visual inspection on two one-year shoots per tree of each variety in all replicates. The T1 treatment demonstrated the highest efficiency, between 84-95%, depending on the year, while the kaolin treatment had the lowest one, but it varied greatly from one year to the other (37-71%).Cacopsylla pyri L. (Hemiptera: Psyllidae) jedan je od najozbiljnijih gospodarskih štetnika kruške u istočnoj Hrvatskoj. Dosadašnje metode suzbijanja štetnika u Republici Hrvatskoj dovele su do rezistentnosti kruškine buhe na pojedine insekticide. Ciljevi dvogodišnjega istraživanja bili su odrediti optimalan broj tretmana s ciljem suzbijanja štetnika na temelju praćenja životnoga ciklusa te utvrditi učinkovitost kaolina u usporedbi s drugim kemijskim insekticidima u četiri različita tretmana (T1: integrirane zaštite bilja (IPM) – diflubenzuron, spirotetramat, abamektin, acetamprid; T2: akrinatrin + abamektin, T3: kaolinska glina, T4: kontrolni tretman). Istraživanje je provedeno 2017. i 2018. godine na pokusnome nasadu kruške starosti šest godina, na tri sorte (Williams, Conference, Abate Fetel) Praćenje populacije štetnika i njezinih razvojnih stadija obavljeno je na dva jednogodišnja izbojka po stablu svake sorte u svim ponavljanjima. Tretman T1 pokazao je najbolje rezultate, s najvećom učinkovitošću od 84 – 95 % ovisno o godini istraživanja, dok je tretman s kaolinom imao najnižu učinkovitost, koja je varirala u odnosu na godinu (37 – 71 %)
