The soybean cyst nematode and control principles

The soybean crop (Glycine max) is one of the most important for Brazilian agriculture, being the agricultural commodity most exported by the country. However, its productivity is limited by the occurrence of various pests and diseases in which the nematode of the soybean cyst (NCS) stands out, whose etiological agent is the phytonematode Heterodera glycines. This phytonematode has caused great damage due to its easy dissemination, high reproductive rate, reasonable survival capacity among others, demanding careful phytosanitary management. Therefore, the principles of control in an integrated way may result in less impact of the phytonematoid in the soybean crop. This review is the section of bioecological systems and the essential use in control of NCS. The principles of exclusion, eradication, evasion, protection, immunization, therapy and regulation are detailed.
