BIOLOGICAL CONTROL OF WEEDS BY MEANS OF PLANT PATHOGENS

Biološka kontrola podrazumijeva primjenu živih korisnih organizama i produkata njihovoga metabolizma u kontroli štetočinja. Biljni patogeni mogu se u suzbijanju korova koristiti na tri različita načina: klasičnom, konzervacijskom i augmentativnom (inokulativnom i inundativnom) biološkom kontrolom. Uz inundativnu biološku kontrolu veže se i primjena bioherbicida (mikoherbicida), odnosno umjetni uzgoj patogena i njihova primjena u određenim fazama razvoja usjeva i korova. Biološka kontrola korova može se primijeniti u sustavima gdje su kemijski herbicidi zabranjeni, gdje postoje rezistentne korovne vrste ili u integriranim sustavima zaštite od korova s reduciranim dozama herbicida i drugim nekemijskim mjerama, no ima određena ograničenja i nedostatke.Biological control is the use of live beneficial organisms and products of their metabolism in the pests control. Plant pathogens can be used for weed control in three different ways: as classical, conservation and augmentative (inoculative and inundated) biological control. Inundated biological control involves the use of bioherbicides (mycoherbicides) or artificial breeding of pathogens and application in specific stages of crops and weeds. Biological control of weeds can be used where chemical herbicides are not allowed, if resistant weed species are present or in the integrated pest management against weeds with reduced herbicides doses and other non-chemical measures, but it has certain limitations and disadvantages
