EVALUATION OF BIOCHEMICAL AND PHYTOTOXIC PROPERTIES OF NEW DERIVATIVES OF BIPHENYL AS POTENTIAL PESTICIDES
Abstract
The article presents data on phytotoxicity and biochemical parameters of the synthesized new derivatives of pesticides, with pesticide properties. Effect of the compounds was evaluated by the degree of response of soil dehydrogenase activity and weight of watercress salad seedlings at different concentrations. Analysis of experimental data showed that all synthesized compounds are toxic to soil microflora and watercress. However, in view of the fact that bis-quaternary ammonium compounds 1 and 2 are largely inhibit the growth of cress salad seedlings and the activity of dehydrogenase even at the lowest concentrations, they are likely to be considered as potential herbicides, and soil application is limited to pre-treatment of seeds. Use of the compounds 3-5 at not low concentrations does not harm any plants or soil microflora. So, they can be regarded as biorational pesticides.
