PHYTOSANITARY STATUS OF WHEAT AGROCENOUSE IN CONDITIONS OF LONG-TERM STATIONARY FIELD EXPERIENCE ON LEACHED CHERNOZEM IN THE WESTERN CISCAUCASIA

abstract 1371803016 issue 137 pp. 77 – 90 30.03.2018 ru 385
As a result of 12-year research, we define the influence of management and control factors on the population of pests and disease damage of four varieties of winter wheat KNIISH of PP Lukyanenko in order to optimize the plant protection factor. The quantitative characteristics of populations of pests and diseases essentially depend on the agronomist and weather predictors. It has been established that for 8 years the population of winter wheat by the larvae of the piano was higher than the EPO and the protection has been important economic and agro-politic. The maximum population of ears of wheat thrips was observed in 2009, 2010, 2013 and 2014 and amounted to 24.2-35.3 specimens / ear, which was the basis for the use insecticides. With optimal weather predictors in 2010, 2011, 2012 and 2013, the population of ears of larvae of wheat mosquito (without plant protection) was from 15.3 to 19.0 specimens / ear, which is higher than the EPO. Monitoring of the dynamics the development of diseases allowed conclusion that the state of the population of pathogens is limited by the levels of fertility and mineral nutrition and weather predictors. The isolation of the values of these indicators in different periods of development of pests allows to optimize the implementation of operational measures with the contribution of the plant protection factor to the productivity of winter wheat from 7 to 42%

PHYTOSANITARY STATUS OF WINTER WHEAT AGROCENOSIS IN THE CONDITIONS OF LONG-TERM STATIONARY FIELD EXPERIENCE ON BLACK LEACHED SOILS OF THE WESTERN CASPIAN CAUCASUS

abstract 1381804042 issue 138 pp. 171 – 184 30.04.2018 ru 503
As a result of 12-year research, we found the influence of management and control factors on the population of pests and disease damage of four varieties of winter wheat in KNIISH of P.P. Lukyanenko in order to optimize the plant protection factor. The quantitative characteristics of populations of pests and diseases essentially depend on the agronomist and weather predictors. It has been established that for 8 years the population of winter wheat by the larvae of cereal leaf beetle was higher than the EPO and the protection has been important economically and agro-politically. The maximum population of spikes of wheat thrips was observed in 2009, 2010, 2013 and 2014 and amounted to 24.2-35.3 specimens / spike, which was the basis for the use of insecticides. With optimal weather predictors in 2010, 2011, 2012 and 2013, the population of spikes with larvae of wheat mosquito (without plant protection) was from 15.3 to 19.0 specimens / spike, which is higher than the EPO. Monitoring of the dynamics the development of diseases allowed conclusion that the state of the population of pathogens is limited by the levels of fertility and mineral nutrition and weather predictors. The isolation of the values of these indicators in different periods of development of pests allows to optimize the implementation of operational measures with the contribution of the plant protection factor to the productivity of winter wheat from 7 to 42%
