STUDIES ON THE APPLICATION OF HERBICIDES IN RASPBERRY CULTURE TECHNOLOGY

Abstract

Weed control in raspberry cultivation helps to reduce the economic impact of the weed control link on the technological cycle, as well as to eliminate competition for water, nutrients and sunlight, thus allowing their growth and development in normal parameters. Cultivation, mulching and herbicide are the most practical control measures. It is necessary to know both the density of weeds and the dominant species in order to establish the strategy to reduce weeding by plowing, herbicide or integrated measures, so that weed invasion falls below the economic damage threshold (PED). The application of herbicides to reduce the degree of weeding is based on the knowledge of the weed species existing in the crop, as well as the state of coverage of the plantation. In order to establish effective measures to reduce the invasion below the economic damage threshold, it is necessary to determine the density of weeds by the method of mapping them and to establish the predominant species. The mapping action took place in the period 2020-2021 and an attempt was made to cover the entire spectrum of weeds in the plantation, then averaging by species. Following the mapping of weeds in the raspberry plantation, the presence of 22 weeds identified inside the metric frame belonging to both the dicotyledonous and monocotyledonous classes was observed, most of them coming from the first group (Capsela bursa-pastoris, Lamium amplexicaule, Cirsium arvense, Cardaria draba, Setaria glauca, Agropyron repens, Cynodon dactylon.
