The status of soil-borne pest control and Integrated Pest Management (IPM) The soil is correctly viewed as a dynamic body consisting of mineral and organic materials, gases and various living organisms (Leeper and Uren, 1993; Van Veen, 1997), some of which are beneficial for soil fertility and plant nutrition, while others –
Soil Solarization. In summer, clear plastic applied to preshaped beds several weeks before planting will solarize the soil and reduce the number of soilborne disease organisms and weed seeds (by making them inviable). On the central coast, this practice requires at least 12 to 15 weeks in order to obtain pest management benefits; consequently ...
