Experiments on dialog models of prognosis of the population density of Globodera rostochiensis in soil at different types of crop rotation

Abstract On predictive dialogue models, computer experiments were carried out to obtain data on the dynamics of population density of golden potato nematode in the soil after growing susceptible potato varieties, globoder-resistant potato varieties and unaffected plants in a 10-field crop rotation. When carrying out computer experiments on the model for predicting the population density of golden potato nematode in the soil after growing globoder resistant potato varieties in a 10-field crop rotation, it was found that when growing these varieties, it will take 8-9 years to completely destroy golden potato nematode population in the soil under favorable or average long-term conditions growing potatoes and other crops. Under unfavorable growing conditions for agricultural crops and globoder resistant potato varieties, the larvae of the ZKN remain in the soil for more than 10 years. In addition to predicting the population density of golden potato nematode after growing unaffected crops and potato varieties of varying degrees of resistance to nematode Globodera rostochiensis, computer models make it possible to theoretically substantiate optimal fruit changes and crop rotations, which will make it possible to effectively clear fields from phytoparasite.
