Abstract

Achievements of soil solarization in Egypt.

Abstract

In field experiments carried out during 1984-89 in Egypt, soil solarization gave good control of Sclerotium cepivorum, on onions and Phytophthora [nicotianae var.] parasitica, Pyrenochaeta lycopersici, Pythium spp. and Rhizoctonia solani on tomatoes. Broomrape [Orobanche sp.] could be controlled for 2 successive years in faba bean or tomato fields by 1 treatment. Amaranthus sp., Portulaca spp., Plantago spp., Chenopodium murale, Vicia sp., Lactuca scariola [L. serriola], Beta vulgaris, Rumex dentatus, Cynodon dactylon, Coronopus squamatus and Sisymbrium irio were effectively controlled, however, Cyperus, Malva spp., Melilotus indica and Convolvulus arvensis were less affected by solarization. Mulching soil, containing a high percentage of salt, resulted in reducing salinity by 30-50%. This paper was presented at the First International Conference on soil solarization held in Amman, Jordan on 19-25 Feb., 1990.
