Soil Solarization An Ecofriendly & Effective Method To Control Soil Borne Diseases

摘要

Soil solarization is an ecofriendly and most effective method of controlling soil borne pathogens and pests by covering moist soil with transparent polyethylene film during hot period for 2 to 6 weeks. It is a hydrothermal process and its success depends on moisture, day length and intensity of light for maximum heat transfer to soil borne organisms. It is a function of time and temperature relationships. It is most effective in region where maximum daily air temperatures commonly exceeding 32°C. It encompasses the objectives of Integrated Pest management (IPM) and reduces the use of toxic chemical in crops.
