Impact of Solarization and Soil Fumigants on Hot Pepper Production in High-Tunnels

Bielinski M. Santos, Jorge E. Mora-Bolanos and J. Arturo Solorzano-Arroyo

Abstract:
High-tunnel studies were conducted in La Ceiba, Alajuela, Costa Rica, to examine the effect of fumigants and solarization on soilborne pest control and Campana hot pepper (Capsicum frutescens L.) marketable yield. Fumigant treatments were: (a) methyl bromide plus chloropicrin (MBr + Pic 98:2 w/w) at a rate of 500 kg ha-1, (b) emulsifiable concentrate of 1,3-dichloropropene (1,3-D) plus Pic at 275 L ha-1, (c) emulsifiable concentrate of metam sodium (metam-Na) at 275 L ha-1 and (d) non-treated control. Soil was either solarized for 8 weeks (average maximum temperature ≈ 60 °C) or not solarized. Solarization reduced the weed densities, but not rootknot nematode populations (Meloidogyne sp.). Similarly, there was no solarization effect on hot pepper yield. Among the fumigants, MBr + Pic and 1,3-D + Pic had the best performance controlling the nematode. Pepper yield in 1,3-D + Pic-treated plots was equal as with MBr + Pic.
