RESEARCH ON THE CHEMICAL CONTROL OF THE INVASIVE SPECIES AILANTHUS ALTISSIMA FROM PASTURES
The present paper presents the results of the chemical control research of the species Ailanthus altissima, an invasive species that damages the lands on which it appears spontaneously, in the form of restricted areas. The total systemic herbicide Roundup, based on glyphosate, 360 g/l was used. Two methods of application were investigated, namely, by brushing on a 30 cm height of the tree trunk and by injection into holes made in the tree trunk. Undiluted herbicide was applied. The first method of application had almost no effect on Ailanthus altissima trees due to the fact that the herbicide cannot be absorbed through the mature bark of the trees. The second method of application gave very good results.
