This article presents the results on the termiticidity of the compounds produced by the reactions of glycyrrhizic acid (GA) with 2-aminothiazole, 3-amino-1,2,4-triazole and 2-aminobenzothiazole. The biological effect of the studied compounds has been found to be dose-dependent. Among the GA derivatives the maximum insecticidal activity has been exhibited by the GA derivative with 2-aminobenzothiazole. Based on the results of the experiments, it has been concluded that the structural-functional approach to the search for biotermiticides is one of the alternative ways to develop environmentally safe means of termite control.

The dynamics of changes in the contents of endogenous phytohormones (ABA and IAA) in sprouts of a cotton line resistant to stresses were studied. A sharp increase of ABA and insignificant change of IAA were noted in the first hours of treatment by salinity and drought. These phytohormones decreased but remained above the control level under the effect of the abiotic stresses. A comparison of proteins in various parts of the sprouts (radicles and hypocotyls) of drought- and salinity-resistant line L-7010 showed that the phytohormones caused under stress both inhibition of the synthesis of several proteins and the induced synthesis of proteins de novo.
