Surprisingly, P. marginalis was also determined before planting in apparently healthy grafted tomato transplants grown in hydroponic culture. Moreover, non-pathogenic P. fluorescens, P. putida, P. synxantha, and Stenotrophomonas malthophilia were identified. The Biolog Identification GN2 MicroPlate™ System System (Biolog, Inc., Hayward, USA) was used for identification of bacterial isolates. Cultures of P. corrugata and P. marginalis were used in a greenhouse pathogenicity experiment. Seven weeks old tomato plants of cv. Moneymaker grown in sterilised perlite were inoculated into the stem with a hypodermic needle at one point above the cotyledon node. In inoculated tomato plants, disease symptoms were observed that included external and internal dark brown lesions around the inoculation site, watering and collapse of pith and sometimes also vascular browning and wilting of leaves. In comparison with P. marginalis, P. corrugata appeared to be a much stronger pathogen. Both tested Pseudomonas species were recovered from inoculated tomato plants. P. corrugata was found to move both upwards to the apex of the stem and downwards from the site of the inoculated stem into roots. When inoculated into potato tuber slices, some tomato strains of P. marginalis, P. fluorescens, P. synxantha, and Pseudomonas sp. produced soft rot. However, other strains of the same species were not able to macerate the potato tissue. It is concluded that P. corrugata and P. marginalis can be associated with the collapse of tomato crop in soilless culture grown in a greenhouse. This is the first report on P. corrugata in tomato plants in the Czech Republic. The role of plant pathogenic bacteria, fungal root rot and vascular pathogens and Pepino mosaic virus in the collapse of tomato plants is discussed.

The causal agent, Phytophthora alni, has spread quickly in the Czech Republic. Hundreds of kilometres of riparian alder stands, especially in the western part of the country, have been severely affected to date. Diseased trees show symptoms characteristic of Phytophthora root and collar rot; these include small, sparse and yellowing foliage, crown dieback, presence of exudates on the bark and necroses of collar and root tissues. Infected trees usually die within a few years, or they become irreversibly damaged, and their function in bank reinforcement declines. The ecological and mechanical functioning of severely affected alder stands may be seriously disrupted.

E. Barr in the Czech Republic Abstract: This study provides new information on the distribution of the chestnut blight agent Cryphonectria parasitica and its vegetative compatibility groups (VCGs) in the Czech Republic. This study has revealed the presence of the disease in six localities. The VCG tests showed that each locality was represented by a single distinct VCG, which was different from the others collected in the country. The tests with 31 European testers of C. parasitica VCGs (EU-1 to EU-31) had assigned Czech isolates to VCGs EU-1, EU-4, EU-12, EU-13, EU-15, and EU-19. Moreover, the study showed that in the Czech Republic chestnut blight attacks young trees, not exceeding 35 years of age, and that climatic conditions in the country are suitable for C. parasitica. As two of the diseased localities were ornamental tree nurseries, one might expect its further spread over the country as a result of plant trade. The origin of infection remains unknown in all the localities where C. parasitica was detected.

Abstract: Tested seed treatments (two doses of thiamethoxam, thiamethoxam + fludioxonil + metalaxyl-M; two doses of clothianidin + beta-cyfluthrin) showed high effects on pea leaf weevils (Sitona lineatus L.) which approved relatively long-lasting and sufficient protection of several bottom nodes of stipules simultaneously. The effects of foliar treatments (chlorpyrifos + cypermethrin; acetamiprid, lambda-cyhalothrin) sometimes were evident only on the node which was determined as the youngest node at the time of spraying. The effects of the compared seed and foliar treatments on the reduction of S. lineauts larvae numbers on roots were not proven as positive. It is possible to conclude that the foliar application had no real effect in this sense at all. However, positive significant effects of thiamethoxam and clothianidin + beta-cyfluthrin on root nodulation in general were recorded. Especially higher doses of the seed treatments increased overall nodulation from 43% till 363%.

Organic wastes were applied at the rate of 15, 30 and 45 metric tons per hectare. Furadan (3G) was applied at the rate of 16, 32 and 64 kg/ha and non-amended plots served as control. The experiment was laid out in randomized complete block design (RCBD). Four weeks old tomato seedlings (cv. Roma VF) susceptible to root knot nematodes were transplanted at a number of eight seedlings per plot of 2 m × 1 m with 45 cm spacing between stands. Fertiliser application, weeding, irrigation and other practices were done as recommended. The results showed that RD treatment gave the significantly (P = 0.05) highest reduction in the nematode population compared to non-amended treatment. It resulted in a significant (P = 0.05) increase in the yield of tomato by 17-100% for RD, 13-84% for SD and 21-63% for RH.
