Cross-Compliance and Fight against Late Blight in Potato within Specific Climatic Conditions of Transylvania, Romania

摘要

Potato production is a basic component of vegetal sector in agriculture. As full member of EU, Romania must fully accomplish the cross-compliance requirements, also in this sector. The aim of our study is to emphasize the results of implementation of the cross-compliance requirements, also in conditions of the use of organic fertilization and organic phytosanitary treatment, respectively, in fight against late blight, compared with efficacy of mineral fertilization or even no fertilization and conventional treatments, in climatic conditions of Transylvania, Romania. Our bifactorial trial - with factors fertilization and treatment against late blight - was implemented for a five month period, during April - August 2014, in a private farm located in Padurenii village, county of Cluj. Best results were obtained when fertilization was performed with N 50 P 60 K 80 , and treatments with Infinito 687.5 SC. Unsatisfactory results were obtained when fertilization was performed with compost, and treatment with Alcupral 50 PU.?? Our study shows that even when cross-compliance requirements are respected, the results of potato phytosanitary protection against lathe blight within Transylvania climatic conditions are effective, provided appropriate phytosanitary treatments and fertilization strategy.
