TI - Soil fumigants provide multiple benefits; alternatives give mixed results JF - California Agriculture JO - Calif Agr Y1 - 1994/05/01 VL - 48 IS - 3 SP - 22 EP - 28 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://dx.doi.org/10.3733/ca.v048n03p22 L3 - 10.3733/ca.v048n03p22 AB - Since the 1950s growers have routinely used soil fumigants such as methyl bromide (MBr) and 1,3-dichloropropene (1,3-D) before replanting orchards and vineyards. Fumigants double plant growth in the early years after replanting and provide several years of nematode relief when resistant rootstocks are unavailable. However, the recent suspension of 1,3-D and the mandated phase-out of methyl bromide by 2001 have clouded the future of fumigant use. To develop alternatives, we must first document the pest control value and plant growth benefit of fumigation. Over the last decade, we have initiated several 2-year field trials in replant sites in the San Joaquin Valley. Our results quantify fumigation benefits and point to the feasibility of some alternatives, including a portable soil drencher.
