Filter Pie in the Control of the Nematoid of Root Lesions in the Soybean and Corn

Abstract

The efficiency of waste from industrial processing has been increasingly studied in the control of phytonematoids, especially filter cake, coffee husks and sugar cane bagasse. The objective of this study was to evaluate the effect of organic residues through the use of filter cake to reduce the population density of Pratylenchus brachyurus (Tylenchida: Pratylenchidae). The first experiment was conducted in a greenhouse in the completely randomized design in the 2 × 4 factorial scheme (soybean genotypes vs. filter cake doses) with four replications using soybean genotypes AS 3810 IPRO and LG60163 IPRO and the second experiment was carried out under the same conditions, with maize AG 1051 with four doses of filter cake with 7 replications. In both experiments, the planting was carried out in an area located in the city of Goianésia, Goiás, Brazil. The results showed that the population density of Pratylenchus brachyurus in the maize crop to grow AG 1051 did not show statistically significant difference by applying the different doses of filter cake. In soybean genotypes AS 3810 IPRO and LG60163 IPRO were affected in ways contrary to phytonematoid infestation, in which AS 3810 IPRO showed a population increase according to the increase of the applied amounts of filter cake, whereas in the cultivar LG60163 IPRO there was a decrease for doses of 10 tonnes/ha-1 and 30 tonnes/ha-1, with an increase of only 20 tonnes/ha-1.

Evaluation of a prototype of soil thermal solarizer for control of gall nematode in the production of coffee seedlings

“…M. incognita is among the species that attack the coffee tree that cause the most damage, due to its great dissemination and ability to damage the root system, (Goulart et al, 2019), making it difficult to insert areas for cultivation, conservation of areas already infested and causing the death of the plant (De Oliveira et al, 2019). They cause peeling, necrosis, lesions and reduction of the root system and the growth of seedlings and young plants, yellowing and leaf fall and chlorosis (Vieira Júnior;Fernandes, 2015).…”

Produtividade E Características Biométricas De Sorgo Sacarino Sob Torta De Filtro / Productivity and Biometric Characteristics of Sorghum Under Filter Pie

“…O emprego da torta de filtro tem apresentado resultados satisfatórios em diversas culturas, tais como, a cana de açúcar nas características produtivas e tecnológicas (VASCONCELOS et al, 2017;ALMEIDA JUNIOR et al, 2011;COSTA et al,2016) soja e milho buscando efeito nutricional e aumentos em produtividade bem como, o efeito do controle de nematoides (OLIVEIRA et al, 2019), desenvolvimento de cultivares de alface (ASSIS et al, 2019), entre outros.…”
