Testing unconventional solutions in fight against late blight and alternariosis in potato, in Transylvainian Plain, Romania

The identification of organic, unconventional, solutions in order to fight against most encountered plant mites and pathogens is a preoccupation of our days. In this context, the aim of our research consists in testing the possibility of using Allium sativum L., and selenium enriched Allium sativum L. in fight against late blight and alternariosis in potato, in conditions of obtaining appropriate interests. A bifactorial experimental design with two graduations, according to the randomized blocks methodology, was implemented in pedo-climatic conditions of Transylvanian Plain, Romania. The data were statistically processed with STATISTICA v 7.0. Basic statistics was used for calculation of means, standard deviations, coefficients of variation, and differences between means, for fungal pathogens attack degrees and potato productions. Our research shows that the use of 1.1% aqueous solution of organic selenium enriched Allium sativum L. is a valuable alternative in fight against Alternaria solani Sorauer, and Phytophthora infestans Mont. De Bary, in both Redsec, and Roclas potato varieties, in studied experimental conditions.
