Produtos naturais aplicados para manejo de Meloidogyne incognita em tomateiros

Abstract: Este trabalho teve por objetivo avaliar o efeito de produtos naturais na expressão da resistência a Meloidogyne incognita em plantas de tomate produzidos organicamente. Os indutores Rocksil, Quitosana, Neemseto e Biopirol foram aplicados 5, 10 e 15 dias, em tratamentos independentes, antes da inoculação do patógeno através da pulverização foliar, utilizando-se duas dosagens para cada indutor. A inoculação do nematoide foi realizada 30 dias após o plantio, usando-se 5000 ovos/ planta. Avaliando-se o número de o… Show more

“…1), where in the majority of the treatments, the means differed statistically, affirming that the presence of the pathogen culminates in lower development of tomato plants, with a lower weight gain. This information is consistent with results obtained by Melo et al (2012) and Moreira and Ferreira (2015), who characterize dwarfism as one of the main symptoms of tomato nematode infections (Dias et al, 2016). In addition to having compromised growth, the infested plants had an apparent reduction of total leaf area, because of a smaller number of leaves, which negatively affected their photosynthetic capacity.…”

“…Wang et al (2017). For nematodes, success has been shown for M. javanica in bananas (Oliveira et al, 2012), rice, beans and soybeans (Mattei et al, 2015), for M. incognita in tomatoes (Melo et al, 2012), and for Enneothrips flavens Moulton 1941 in peanuts (Dalastra et al, 2011), among others.…”

“…Studies focused on pyroligneous extracts have shown important bio-activity for other plant-parasitic nematodes, and the efficacy of these products can also occur through indirect action by the plant-induced resistance. The pyroligneous extract Biopirol ® (aqueous phase obtained in the distillation of eucaliptus tar), for example, was used as resistance inducer and showed efficacy to reduce the number of eggs and the reproduction factor of M. incognita in tomato (Solanum lycopersicum L.), at the lowest concentration tested (0.5%) in all application periods (Melo et al, 2012). In another study, Biopirol ® reduced the hatching of second stage juveniles of M. incognita, M. javanica (Treub) Chitwood, and Tylenchulus semipenetrans Cobb, and also the formation of galls by M. incognita and M. javanica in tomato roots (Corbani, 2008).…”

“…The parasitized plants present reduced growth but remain green, being in a stage of partial or total obscuration during the penetration of cortical and corticoid cells, instead of neutralizing the toxins during the feeding process. In addition, the movement of the parasites through the root is disorganized, aiding in the destruction of cells [33,65].…”
