Variedades de soja resistente, nematicida químico, nematicida biológico, plantas não hospedeiras

Abstract

Soybean is one of the most important crop in the world. However, obtaining better yields has been limited by the spread of diseases and pests attack. Thus, the presence of plant-parasitic nematodes has begun to have a greater economic importance, stand out Heterodera glycines, Meloidogyne spp, Pratylenchus brachyurus and Rotylenchulus reniformis, which are considered some of the most important species in soybean crop. To control this pathogen it is necessary to adopt an integrated nematode management, combining more than one control measure in order to reduce population levels, since the totally eradication of the pest is considered impossible. With that in mind, the objective of the work was to carry out a systematic review, with the aim to gather control measures for controlling nematodes on soybean crop in the state of Mato Grosso. In order to indicate the main biological and chemical nematicide products registered by MAPA, the resistant plant varieties, as well as non-host plants recommended for succession cropping and rotation cropping for state of Mato Grosso. For this work, a descriptive documentary research was carried out from websites and media. At the end of the survey, it was found about 120 soybean varieties with resistance against nematodes recommended for at least one of the 401, 402 and 403 micro-region. Besides, there are currently 51 microbial products used as biological control and 20 products as chemical control of nematodes registered by MAPA. How about non-host plants indicated for the control of plant-parasitic nematodes, 14 cultures were found. Thus, it is concluded that the current market provides a wide range of plant-parasitic nematode management and control strategies for the state of Mato Grosso.
