| مستخلص: | Efficacies of phosphorous acid (PA) and potassium silicate (KSi) foliage applications against collar rots caused by Phytophthora× cambivoraand P. cinnamomiwas investigated on three-year-old chestnut saplings in Bolu province under field conditions. Protective effects of PA and KSi were determined in two treatment modes. For the first mode, the chemicals were sprayed onto the saplings first, and the pathogens were inoculated after one or two weeks from the treatments. For the second mode, the pathogens were inoculated first, and then the chemicals were applied after a week. Evaluation of the treatments was made by measuring the lesion lengths after 28 and 35 days from the inoculations. PA treatments (4 ml/l of 40% Agrifos) made before the inoculations showed more than 90% effectiveness against both P.× cambivoraand P. cinnamomiinfections, the effectiveness on the latter being higher. A high rate of protection was also achieved by the applications of PA two weeks before the inoculations, even after 5 weeks from the challenges by the pathogens. Applications of PA after the infections did not provide a high rate of protection. KSi foliage treatments (10 mM of KSi salt) made on both ways did not show any protection against collar rots caused by Phytophthoraspp. |
