PESSOA, Milene Magalhães. Population survey of phytonematoids in soybean crop in the municipality of Montividiu - GO. 2019. 27p. Monography (Bachelor's Degree in Agronomy). Federal Institute of Education, Science and Technology Goiano - Rio Verde Campus, Rio Verde, GO, 2019.

Among the organisms that cause the loss of the main crops of economic importance, the nematodes stand out. Parasitic diseases may not occur with the absence of host plant response, cause parasitized forms, and participate in the disease cycle in different ways. The nematodes most damaging to soybeans are Heterodera glycines and root diseases, Pratylenchus sp. The sierras in the roots, the cultural remains and the soils in several cases deposit the structures of resistance. Alternative structures can remain without soil for many years. The objective of this work was to carry out the population survey of H. glycines and Pratylenchus sp. in the city of Montividiu - GO. The samples that were collected were the symptoms, as plants of low size, during a harvest of 2018 / 2019. In the laboratory, the samples were extracted and performed a quantification, where it was found a higher incidence of Pratylenchus sp.
