chitosan (biochikol 020 pc) in the control of some ornamental foliage diseases.	chitosan, (biochikol 020 pc) a potential elicitor of plant defence and also an active inhibitor of fungal growth was used in experiments. the compound was used at concentrations 0.01 to 0.2% as a plant spray for rose protection against sphaerotheca pannosa var. rosae, peronospora sparsa and diplocarpon rosae, oidium chrysanthemi and puccinia horiana on chrysanthemum, against melampsora epitea on willow. myrothecium roridum on dieffenbachia and against lophodermium spp on scots pine. effectivenes ...	2004	15756862
downy mildews on ornamental plants and their control.	among downy mildews occurring on ornamentals in poland the most dangerous are downy mildew of rose and downy mildew of german statice (tartarian statice). downy mildew of rose caused by peronospora sparsa berk. is a serious threat to commercial cultivation of cut roses, especially grown under plastic tunnels. peronospora statices lobik casual agent of german statice downy mildew can causes the total losses in the second year of statice cultivation more than 70%. both pathogens are very difficult ...	2006	17390852
simple sequence repeat markers useful for sorghum downy mildew (peronosclerospora sorghi) and related species.	a recent outbreak of sorghum downy mildew in texas has led to the discovery of both metalaxyl resistance and a new pathotype in the causal organism, peronosclerospora sorghi. these observations and the difficulty in resolving among phylogenetically related downy mildew pathogens dramatically point out the need for simply scored markers in order to differentiate among isolates and species, and to study the population structure within these obligate oomycetes. here we present the initial results f ...	2008	19040756
impact of agrochemicals on peronospora sparsa and phenolic profiles in three rubus arcticus cultivars.	the main arctic bramble ( rubus arcticus) cultivars are susceptible to downy mildew ( peronospora sparsa), which seriously threatens the cultivation. the efficiency of aliette, euparen m, phosphite-containing phosfik, phostrol, farm-fos-44, and kaliumfosfiet, as well as bion was evaluated in the greenhouse. fewer symptoms and less peronospora dna were found in plants treated with euparen m and bion, whereas aliette, phosfik, and phostrol gave moderate protection. three arctic bramble cultivars s ...	2008	18183950
benzothiadiazole affects the leaf proteome in arctic bramble (rubus arcticus).	benzothiadiazole (bth) induces resistance to the downy mildew pathogen, peronospora sparsa, in arctic bramble, but the basis for the bth-induced resistance is unknown. arctic bramble cv. mespi was treated with bth to study the changes in leaf proteome and to identify proteins with a putative role in disease resistance. first, bth induced strong expression of one pr-1 protein isoform, which was also induced by salicylic acid (sa). the pr-1 was responsive to bth and exogenous sa despite a high end ...	2008	19019008
