Polyclonal antisera to detect and determine two related pathovars, Pseudomonas syringae pv. pisi and Pseudomonas syringae pv. syringae, were prepared Untreated bacterial cells, or fixed by formaldehyde or glutaraldehyde were used as antigens. After cross-absorption with heterologous antigens, antisera revealed a high level of specificity in slide agglutination, Ouchterlony gel double-diffusion and in DAS-ELISA and PTA-ELISA. Each of 14 P s. pisi prepared polyclonal antisera could detect and deter mine all strains of P s. pisi, regardless of race. PTA-ELISA was...

In 1997-1998 virulence of the leaf rust population was studied on near isogenic Thatcher lines with the genes for resistance Lr1, Lr2a, Lr2b, Lr2c, Lr3, Lr9, Lrll, Lr15, Lr/7, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28, and on the standard differentials Mala koff, Carina, Brevit, Webster, Loros, Mediterranean, Hussar, Democrat and the supplemental cultivar Salzmtinder Bartweizen. All 55 analyzed rust samples were avirulent on Lr9, Lr19, Lr24 and Lr28.On the...

A survey on the occurrence of plum pox virus (PPV) in plums, myrobalans, blackthorns, apricots and peaches was carried out in the South Moravian region along the Austrian border. Results of tests by ELISA and evaluation of PPV symptoms showed only scattered or isolated occurrence of PPV. This situation can be used for gradual elimination of PPV in the South Moravian region.

The infestation of barley grains by fungi of the genus Fusarium was studied on malting barley from Kromei'iz (360 samples) and one sample from Kojet!n in Czech Republic. Most frequent species in the season 1997-1998 were: F. culmorum (over 70% of the isolates), F. poae (over 20% of the isolates), F. avenaceum (over 2%). Much less frequent were: F. stilboides v. stilboides, F. aqaeductum v. aqaeductum, F. merismoides v. merismoides and F. gigas....
Seed size and dormancy in Rumex obtusifoliusOriginal Paper

Plant Protect. Sci., 1999, 35(3):103-107 | DOI: 10.17221/9707-PPS
We tested the hypothesis, suggested by literature data, that in Rumex obtusifolius L. the germination of matured seeds harvested from dry standing shoots and achene morphology are correlated. In these seed materials the level of germination is determined by the incidence of primary seed dormancy. The regression of the percentage of germinating seeds on achene, perianth and seed size and mass were calculated for seed materials of 30 plants. The materials in which achene morphology was investigated were selected ex post from a set of seed materials of 241 plants to cover the range of variation of germinability of individual...
Pathogenicity of Beauveria bassiana strains isolated from Ostrinia nubilalis Hbn. (Lepidoptera: Pyralidae) to original host and to ladybirds (Coleoptera: Coccinelidae)Original Paper

B. bassiana strains isolated from 0. nubilalis were tested against the larvae of 0. nubilalis and coccinellid beetles in laboratory conditions (25°C). The first dead 0. nubilalis larvae were observed 48 hours after the application. During the first five days after the application, the efficiency of spore suspension was significantly higher than the efficiency of dry spore formulation. Spore suspension killed more than 50% of larvae after 72, or 96 hours. After dry spore formulation was used, more than 50% of larvae were killed during 96, or 120 hours. B. bassiana killed 50% of coccinellid larvae...
