Absorption, Translocation and Degradation of N-Lauroyl-L-valine in Plants

Abstract

One of amino acid pesticides, N-lauroyl-L-valine was developed for plant diseases. Absorption, translocation and metabolism in rice plant and cucumber plant were investigated using N-lauroyl-L-valine-¹⁴C. N-lauroyl-L-valine-¹⁴C solution was applied on the healthy leaf of rice plant or cucumber plant, no radioactivity was found around the deposit site. But the activity was found on the injured rice plant and on the injured leaf or fruit of cucumber. Production of ¹⁴CO₂ from the experiment incubating N-lauroyl-L-valine-¹⁴C with cell preparation of rice plant or a fruit of cucumber was detected slightly. From these results, attitude of N-lauroyl-L-valine applied in nature were reasoned.
