(Diseases and Management of Crops under Protected Cultivation) Biological Control of Soil Borne Pathogens under Green House Conditions J. Kumar Department of Plant Pathology, G.B.P.U.A.& T., Pantnagar-263 145 (UK) Global scenario of green house/protected cultivation: Green house cultivation is a form of protected cultivation which has some level of control over plant microclimate to alleviate one or more of abiotic stress for optimum plant growth. The green house technology is more than 200 year old and Europeans were considered the pioneers in this field. Later with the advent of plastic during World War II a new phase in the glass house technology emerged. The world’s total greenhouse area is more than 307,000 ha which includes both plastic and glass poly houses. There are more than 50 countries in the world where cultivation of crops is undertaken on a commercial scale under cover. Green houses permit production of crops even in areas where winters are severe and extremely cold as in Canada and Russia, and also in areas where summers are extremely intolerable as in Israel, UAE, and Kuwait. Country wise area under green house crop production Country USA Spain Italy The Netherlands Israel Egypt China Japan South Korea Area under green house production >400 ha 25,000 ha 18,500 ha 89,600 ha 15,000 ha 1000 ha 48,000 ha >40,000 ha >21,000 ha Status of Green house cultivation in India: In India green house technology is still in its nascent stage. The area under green/poly house cultivation, in the end of 2011 was about 2000 hectares. Maharashtra, Uttarakhand, Karnataka and Jammu & Kashmir are the major states having cultivation of crops under green house. According to the Directorate of Horticulture, Govt. of Uttarakhand, in 2011, the total area under polyhouse in Uttarakhand is 200ha. Vegetables, flowers, medicinal and aromatic plants are considered as most successful and revenue generating crops grown in this technology. All these crops have high productivity in green houses due to reduction in competition, healthy environment, better nutrient management, increased surface area and longer crop duration. Disease Problems in Greenhouses: The ideal and stable environment with warm, humid and abundant food under green house provides an excellent platform for the development of diseases often more than field conditions. Most pathogens cannot be excluded from the greenhouse environment, for example airborne spores enter through doors and screens; soilborne pathogens enter through dust or contaminated soil on shoes, tools, or equipment; and many pathogens are - 134 -
