PREFACE

Modern commodity agriculture in term of weed control is based, dominantly, on the achievements of chemistry. Herbicides as agrochemicals are used in agriculture for over half a century for this propose. Along with the discovery of new herbicides groups continuous selection takes place due to what currently recommended herbicides have very low toxicity to man, and animals and environment as well. The mode of action of presently preferred compounds is based on the inhibition of metabolic processes ongoing only in plants: inhibition of photosynthesis, cell wall elements biosynthesis and the synthesis of branched chain amino acids, with enzyme acetolactate synthase as for example. However, it has to be kept in mind that every living organism subjected to pressure is trying to adapt to the new environment. The consequence of this phenomenon is the appearance of resistant weeds.

At present in many countries resistance to herbicides that inhibit acetolactate synthase dominates. The scale in number of resistant species and area of appearance should awaken our attention in perspective of commercial agriculture. Red light for us should be that most of these compounds is used in the cultivation of cereal crops, which occupy more than 50% of the arable land in Poland. It is especially danger that this type of resistance appeared in the most troublesome weed species cereals i.e. Apera spica venti. We should remember that slow time of development of this phenomenon outcomes from the continuous crossing between resistant and sensitive biotypes from surrounded sites. This type of resistance is likely to occur on a really large scale when critical mass of resistant biotypes will be reached. The purpose of this minisymposium is to present the problem of resistance to acetolactate synthase inhibiting herbicides and attempts to cope this challenge in Poland.
