Efficiency of application of growth regulators based on trinexapak-ethyl on winter wheat
Abstract
The article presents the results of many years of research on the effectiveness of plant growth regulators based on trinexapac-ethyl on winter wheat. Correlations have been constructed between the number of stems in the BBCH 31–32 phase and the density of the productive stem with resistance to lodging of winter wheat, between the rate of germination of the growth regulator Moddus, CE and the length of the internodes. The effectiveness of the methods of using retardants based on trinexapac-ethyl on the resistance to lodging of winter wheat and their effect on the elements of productivity and crop yield is shown. The introduction of trinexapac-ethyl into the phase of BBCH 31– 32 (70–105 g/ha d. v.) increases the resistance to lodging by 2,0–4,5 points and retains an average of 6,8 c/ha of grain. The double use of growth regulators in the phases of BBCH 31–32→39–49 by 35–50 g/ha increases the resistance to lodging by 2,0–6,0 points and retains an average of 6,2 c/ha of grain.
