- Effect of nematicide rotation on banana (Musa AAA cv. Williams) root nematode control and crop yield Julio Jaramillo Marlon Vintimilla David Rubio Gonzalo Soto Mauricio Tobar Eduardo Salas Mario Araya Agrociencias nematicide root weight Cavendish subgroup Radopholus similis Helicotylenchus spp The effects of nematicide rotation on banana (Musa AAA cv. Williams) root weight, root nematode control, and crop yield were compared in a commercial banana plantation in Ecuador, testing six treatments in a randomized complete block design with six replicates. Treatments consisted of two, three and four different nematicide cycles per year plus the untreated control. Regarding the untreated plants and averaging the 24 root nematode samplings after treatment application, the nematicide applications reduced significantly R. similis (P<0.0001) between 20 and 49%, Helicotylenchus spp. (P<0.0001) between 31 and 51%, and total nematode populations (P<0.0001) between 29 and 49%. Accordingly, in the treated plants, there was an increase between 16 and 21% in living root weight (P=0.0003), and its percentage (P<0.0001) reached between 74.5 and 81.7% in the follower suckers. In addition, the death of roots by nematodes decreased (P=0.0009) between 20 and 46%. At harvest, nematicide applications increased bunch weight (P=0.0002; P=0.0467), ratio (P=0.0003 at 12 months), ratooning (P<0.0001; P<0.0001) and the number of boxes of 18.14 kg (P<0.0001; P=0.0005) per hectare per year at 12 and 24 months after treatment application, respectively. Plants treated with nematicides increased yield between 671 and 1,158 (12.2 - 21 t) and the number of boxes of 18.14 kg per hectare per year also increased between 545 and 1,046 (9.9 - 19.0 t), which resulted in a net profit between US $3,266 - $5,750 and between US $2,587 and $5,144 per hectare per year at 12 and 24 months after treatment application, respectively. 2019 artículo científico 0120-9965 https://www.redalyc.org/articulo.oa?id=180363224007 https://www.redalyc.org/journal/1803/180363224007/ https://www.redalyc.org/journal/1803/180363224007/html/ https://www.redalyc.org/journal/1803/180363224007/180363224007.epub https://www.redalyc.org/journal/1803/180363224007/movil 10.15446/agron.colomb.v37n2.79099 en http://www.redalyc.org/revista.oa?id=1803 Agronomía Colombiana application/pdf Universidad Nacional de Colombia Agronomía Colombiana (Colombia) Num.2 Vol.37
