“…The growing search for less polluting and renewable fuels has turned the sugarcane market into one of the world's most promising in agribusinesses, favoring the expansion of the sugarcane industry. However, despite the Brazilian tradition in sugarcane production, sugarcane productivity is regulated by several factors, with health problems reducing crop productivity in different producing regions, especially those caused by nematodes (BELLÉ et al, 2017;PORTO et al, 2018).…”

“…The damage caused by nematodes varies according to the population level, soil type, and crop variety (SILVA et al, 2016;BELLÉ et al, 2017;NORONHA et al, 2017;MARANHÃO et al, 2018). When at a high population density, nematodes cause severe damage to the root system, which becomes underdeveloped and inefficient, leading to decreased productivities (SILVA et al, 2017;PORTO et al, 2018).…”

The root-lesion nematodes Pratylenchus spp. have a wide geographic distribution and a large number of host plants. These migratory endoparasites are found associated with sugarcane around the world causing diseases that induce permanent losses in productivity. Although this genus has ordinarily been reported in low-producing sugarcane areas in northeastern Brazil, studies of the species occurrence are few and restricted to a very low number of sites and samples. This study aimed to morphologically and morphometrically characterize Pratylenchus species from different sugarcane regions of Pernambuco state, where composite samples of soil and roots were collected on 30 farms from three sugarcane mills. The external morphological characters of the nematode body from different populations had a diagnostic value compatible with those obtained in the literature, showing the dominance of P. zeae (87%) in the region. Atypical populations of the genus Pratylenchus were also found.

“…Brida et al (2017) explain that the nematode P. brachyurus can penetrate and grow in roots regardless of the soybean cultivar analyzed. Matsuo et al (2012) and Bellé et al (2017) found differences between soybean and sugarcane genotypes, respectively, and classified them as resistant and moderately resistant to Heterodera glycines, Meloidogyne javanica, and Pratylenchus zeae, respectively.…”

Irrigation management in soybean crops influences the occurrence of nematodes in the soil

et al. 2020

One of the main limitations of soybean production is related to water availability and organisms found in the soil. Under the hypothesis that soil moisture may influence the nematode population, this study aimed to verify the occurrence of nematodes associated with different irrigation management in soybean crops. The experiment was carried out in a randomized block design. Treatments consisted of a subplot scheme, with four replications. The plots consisted of ten irrigation managements divided into five irrigation frequencies (1,2,3,4, and 5 days) and five additional water depths (25, 50, 75, 100, and 125% of crop evapotranspiration – Etc). The subplots were composed of four different soybean cultivars (NA 5909 RR, AS 3680 IPRO, and Desafio RR ePower IPRO). The experiment analyzed the variables plant height, first pod insertion, number of plants, moisture, hundred-grain weight, yield, and occurrence of nematode eggs and adults. Nematodes influence all the production components analyzed, affecting mostly the hundred-grain weight, especially the nematode Helicotylenchus sp., although the Meloidogyne sp. population was larger. The phytonematode population reduces with the increase in soil moisture to levels close to the saturation, indirectly influencing the yield increase.

Quando em alta densidade populacional, os nematoides causam graves danos ao sistema radicular, que se torna subdesenvolvido e ineficiente, levando à diminuição das produtividades (SILVA et al, 2017;PORTO et al,2018).…”
