Multi-Ligand Copper Complex with Fungicidal and Stimulating Effect for Increasing the Germination and Phytosafety of Plants

Abstract

Abstract At present, when the whole world is intensively switching to organic farming, the refusal or minimization of the usage of chemical plant protection products and synthesized fertilizers is a very urgent issue of the agro-industrial complex (AIC). Accordingly, the solution to the problems of increasing yields and ensuring the fight against pathogenic components should be carried out in accordance with the principles of "green" chemistry. In this regard, usage of mixed-ligand complexes based on carboxylic and amino acids with biogenic metals is dictated not only by their availability, low cost, and the ability to increase crop yields, but also by fungicidal activity, less toxicity, easily biodegradability, which lists them among the "green" ones and cost-effective plant biostimulants. In the present work, mixed ligand complex based on succinic acid, glycine and copper with the formula [Cu(succ)(gly)]n, was developed for usage as a fungicidal biostimulant, which has the ability to significantly reduce the number of pathogens. We have found that this compound has a layered structure and can increase soybean germination up to 100%.
