Influence of proplis in growth Pythium irregulare and Fusarium solani

Abstract

Proučavali smo utjecaj propolisa na dvije fitopatogene gljivice, Fusarium solani i Pythium irregulare. Oba patogena prave velike štete na usjevima, kako u svijetu tako i u Hrvatskoj. Kontrola od ovih uzročnika bolesti se provodi osim agrotehničkim i kemijskim mjerama borbe što vjerojatno jeste ekonomski isplativiji način suzbijanja, ali je i nepovoljniji za okoliš i čovjeka. Alternativa za suzbijanje ovih patogena jeste ekološki način suzbijanja, u koji spada i propolis. Propolis je proizvod pčela, koji prvenstveno njima služi za dezinfekciju i zaštitu košnice kojom nastoje eliminirati sve štetne organizme koji su u doticaju s košnicom. U istraživanju smo koristili tri koncentracije propolisa u alkoholnoj otopini, a to su 0,5 %, 1 % i 2,5 %. Za Pythium irregulare, sve tri koncentracije su se pokazale uspješne u inhibiciji rasta micelija, koji u ovom slučaju nije uopće porastao. Za Fusarium solani je utvrđeno da koncentracija propolisa od 2,5 % u potpunosti inhibira rast Fusarium solani dok je na nižim koncentracijama zabilježen manji porast, ali statistički značajno manji od kontrole.We studied the influence of propolis on two pathogenic fungus, Fusarium solani and Pythium irregulare. Both pathogens make damage to crops worldwide and in Croatia. So far, they are suppressed by using fungicides, which is probably more cost-effective way to control, but it is worse for the environment and human. The alternative for the control of these pathogens is an environmentally friendly way to combat, which includes propolis. Propolis is a bee product, which primarily serves them for disinfection and protection of the hive, which seek to eliminate all harmful organisms that come into contact with the hive. We used three concentrations of propolis in alcoholic solution 0.5 %, 1 % and 2.5 %. The suppression of Pythium irregulare, all three concentrations have proved successful in inhibiting the growth of mycelium, which in this case is not at all increased. The suppression of Fusarium solani, as the best solution proved to be expected, the highest concentration of propolis, or those of 2.5 %, which was completely inhibited the growth of Fusarium solani, while the lower concentration recorded minor increase, but significantly higher than the control
