Lypytan R. Scientific rationale for protection of crops from sugar beet re-clogging in the right-bank part of the forest-steppe zone of Ukraine

The thesis presents the results of research the author's comprehensive study of specific re-clogging of sugar beet and factors affecting the productivity of the plants of culture in conditions of sufficient moisture. The possibility of achieving the required level of dominance of plant culture in the second half of the growing season due to formation of a sufficient optical density (5-6 pcs./m row), the effective destruction of the primary debris herbicides and reliable and environmentally phytocentral control processes re-clogging of sugar beet by reducing the intensity of the incident PAR energy flux at the surface of the soil to not less than 5-6%. During conditions of energy deficit of the new plants are not weeds can significantly affect the level of productivity of crops. Study and recommend a system of successive spraying herbicides and rational use of environmental methods of controlling phytocentral seedling weeds re-blockage by the most complete absorption of the incident energy flux of PAR optically dense foliated plant culture apparatus at a time when herbicide use is not possible and economically feasible. Developed a system of measures allow for effective protection of sugar beet under conditions of sufficient moisture.
