COMPOSITION FOR COMBATING AMBROZY

Journal Title: Наукові доповіді НУБіП України - Year 2019, Vol 1, Issue 1

Abstract

The actual problem of controlling widespread and harmful types of weeds, which cause considerable damage to agriculture, is highlighted. Ambrosia of the polystyrene Ambrosia artemisiifolia L, which has spread quite rapidly in almost all European countries, including Ukraine, is particularly harmful among these weeds. The complexity of the problem of the destruction of ambergris is to ban the use of herbicides that pollute groundwater and soils, endangering the flora and fauna of ecosystems. The goal was to develop a composition based on organo-minerals and surfactants for combating ambrozia. The research was conducted using modern methods of experiment planning, which allowed reducing the amount of experimental work and obtaining a regression equation describing the effect of various factors on the activity of amygdala. The factors influencing the time of destruction of ambrasia were chosen: organomineral substance, superficially active substance and fatty acids. Experiments were conducted on selected land plots with plants of ambergris, which were exposed to the substances of the selected factors. A statistical analysis of the results of the study was carried out, which confirmed the adequacy of the mathematical model obtained, which describes the dependence of the effect on the time of destruction of the ambrasic composition of the composition on the basis of organo- mineral, surfactants and fatty acids. Graphs of dependence of influence on the time of destruction of ambrasian organomineral substance and surfactant with two different contents of fatty acids are given. The research was conducted at the National University of Life Sciences and Natural Resources of Ukraine and the Ukrainian State Research Institute "Resource". The results of the study showed that the most significant effect on the time of destruction of ambrasia makes organomineral substance, and the least - fatty acids, and, with an increase in their number, the time for destruction of ambrasia increases. The developed composition inhibits the growth of ambrasia, promotes leaf fall and its drying and extinction of the root system and does not endanger the flora and fauna of ecosystems. The author's proposed composition based on organo-mineral substances in comparison with the existing ones is an effective means of combating ambrozia, does not require costly technological processes for its preparation, can be prepared directly at the place of its application, has a low price and can be effectively used in any agricultural sector.
