  1. Pest regulation: Plant or maintain ground cover in orchards or vineyards

    A replicated, randomized, controlled study in 2002 in a pistachio orchard in the San Joaquin Valley, California, USA, found more pests in plots with ground cover, compared to plots with tilled soils. Pest numbers: More Amyelois transitella navel orangeworm moths were found in plots with ground cover (without tillage in the drive rows between rows of trees), compared to plots with tilled soils, in one of two comparisons (with unmown ground cover: 7 vs 1). Implementation options: Fewer moths were found in plots with ground cover that was mown, compared to unmown (9 vs 2). Methods: There were six plots (11 square feet/plot) for each of two treatments (ground cover in the drive rows, with or without mowing), and there were six control plots (tillage between the drive rows with a disk plough; depth not reported). The ground cover was resident vegetation. Before mowing or disking, two hundred pistachio nuts, infested with navel orangeworm larvae, were placed in each plot (about 71 larvae/plot). The plots were then covered with cloth, and moths were counted every week, after they emerged from the nuts.
