Abstract
Abstract ‘Redglobe’ peaches ( Prunus persica (L.) Batsch) were grown under drip irrigation and no irrigation, with and without fumigation with 1,2–dibromo–3–chloropropane (DBCP). The irrigation treatments were 1) nonirrigated, 2) irrigated until harvest, 3) irrigated from harvest to dormancy, 4) irrigated all season. Fumigation increased trunk cross-sectional area by 18 cm 2 , and when postharvest water was applied the increase was 25 cm 2 at the end of 1978. Irrigation increased marketable yields of fresh peaches from 3.6 to 7.4 MT/ha (62-150 bu/acre) in 1977. In 1978, fumigation did not increase yields unless preharvest water was applied; then, yields were increased from 12.1 to 17.2 MT/ha (232-357 bu/acre). Fumigation apparently increased water use as indicated by the increased rate of controlled water application. Fumigation reduced populations of Macroposthonia xenoplax (Raski) DeGrisse and Loof, from a range of 30-400 to a range of 1-30 nematodes/150 cm 3 of soil.
