The present study focused on potential risks resulting from selected fruit, vegetable and cereal samples with pesticide residues exceeding maximum residue levels (MRLs) from a 5-year survey of official control in Poland (2017–2021). A novel, common tool, the EFSA Pesticide Residue Intake Model PRIMo was used for short-term exposure calculation with embedded consumption data from EU Member States. The challenge of the research was to determine whether the International Estimated Short Time Intakes (IESTI) of toxic pesticides in the diet are acceptable or not. For the first time with long-term investigation which involved many legislative changes, we prepared a picture of the most dangerous pesticides present in fruits, vegetables and cereals for the most critical sub-populations of adults and children. We examined whether these substances have the potential to cause harm to humans. From the full spectrum of 545 analyzed pesticides, we considered 13 pesticides above safety limits in the concentration range of 0.03 to 2.5 mg · kg –1 . The most frequently detected compound was the non-authorized, organo-phospate insecticide chlorpyrifos, which poses toxicological risks to humans. The results of acute exposure were up to 93% ARfD for adults and up to 130% for children. The Hazard Quotient (HQ) showed that consumption of agricultural plants with potential risk can be safe for adults and children, with some exceptions. Samples containing flonicamid/Brussel sprouts (HQ = 1.3) and chlorpyrifos/rucola (HQ = 1.1) could have negative health effects on humans. However, an approach which overestimates the exposure due to a worst-case scenario ensures the widest possible safety margin for the consumers.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"49 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work was to develop and apply, under field conditions, different fungal formulations using entomopathogenic fungi to control R. nu larvae. The mortality percentages in bioassays of R. nu larvae treated with different colonies of fungal entomopathogens ranged between 86.6 ± 8.4% for Beauveria bassiana (LPSc 1098) and 56.6 ± 4.2% for Metarhizium anisopliae (LPSc 907).

This study aimed to elucidate the influence of E. plana rhizosphere soil on wheat germination and initial development. Bioassays with soil sampled from an infested agroecosystem were carried out using wheat as the target species. A factorial design was used, crossing soil from the horizontal and vertical distances from the E. plana tiller base and considering seasons as a blocking factor. The interaction between season and vertical and horizontal soil positions influenced normal wheat seed germination, with the lowest values (69%) observed in the winter bottom and intermediate soil positions. The highest abnormal seedling percentage (17.6%) was recorded in the summer middle vertical soil position. Dormant wheat seeds were higher (7%) in the spring bottom and distal soil positions. The season was the most important factor for germination, but hypocotyl, radicle, and total wheat seedling length also varied according to soil position. Shorter hypocotyls and seedlings were registered in the summer soil surface, while shorter radicles were observed in the proximal horizontal soil position in the same season. This variable response of wheat germination and seedling development to the infested soil demonstrated E. plana seasonality. The influence also varied according to the distance from the plant tiller base. These findings may be used to improve E. plana management in infested fields and to understand the mechanism of action of its allelochemicals in future research.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"47 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The competition of annual bluegrass with ryegrass can interfere with crop growth and reduce the amount of forage for animal feed. We aimed to evaluate the interference of annual bluegrass in ryegrass crops through the differentiation of niche and establishment. Two experiments were carried out testing different competition strata (shoot, root, and both) and ryegrass establishment with or after annual bluegrass, with increasing populations of annual bluegrass (0, 35, 139, 279, 419 plants m –2 ). The variables were plant height, height length of the root system, stem diameter, and fresh weight of shoot and root systems of ryegrass. The negative interference of growing populations of annual bluegrass occurred when in competition for the shoot and root systems of ryegrass. The fresh weight of shoots and roots were impacted when competing for the same strata. Ryegrass, established after the population of annual bluegrass, showed less competitive capacity. The negative interference of annual bluegrass in ryegrass is greater when the plants fully compete for the resources of the environment, and when the ryegrass establishes after the competitor.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"51 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it should primarily be retained on farm-lands to prevent soil organic matter (SOM) losses. Straw retained on the field is usually incorporated into the soil when conventional (with ploughing) and reduced tillage systems are used or left on the soil surface (mulching) when a no-tillage system is practiced. The aim of this study was to determine how different straw management practices (straw removal, straw incorporation and straw mulching) affected the incidence of Cephalospo-rium gramineum on two winter wheat cultivars, the grain yield of these cultivars and selected soil properties based on a long-term micro-plot experiment. Cephalosporium stripe disease was absent or occurred at very low levels (0–2.4%) when straw was removed or incorporated every second year. The disease was most severe, 24–33% tillers infected, in the SM(N) treatment with yearly straw mulching and cv. Bogatka was more tolerant to C. gramineum infection than cv. Bamberka. Importantly, yearly straw incorporation into the soil in contrast to straw mulching resulted in low disease levels (5–8% tillers infected) in both cultivars. Only in the case of cv. Bamberka was the grain yield significantly reduced in the SM(N) treatment compared to other treatments. The soil in this experiment contained the lowest level of soil SOM, which amounted to 21.0 g ∙ kg –1 soil dry matter (DM), when each year wheat straw was removed (SR). Straw incorporation every second year resulted in 24.2 g of SOM ∙ kg –1 soil and the largest amounts of SOM (26.0–26.1 g ∙ kg –1 soil) were found with yearly straw incorporation into the soil. Yearly straw mulching was inferior in this respect and the soil in this treatment contained 23.8 g of SOM ∙ kg –1 soil DM.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"50 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, to achieve sustainable and residue-free production, control alternatives must be explored. This work proposes the use of Beauveria bassiana (BB) in combination with inter-row cover (IC) to reduce the population of thrips and the incidence of TSWV on bell pepper. For this purpose, a trial was carried out in a bell pepper greenhouse, consisting of four randomly distributed treatments with four repetitions of 66 plants each. The treatments assayed were: T (without BB inoculation or IC), TC (without BB inoculation and with IC), B (inoculated with BB), and BC (inoculated with BB and IC). The B. bassiana CEP147 strain was used based on its effectiveness in previous laboratory tests. After detecting one thrips per flower, five foliar spray applications were made at weekly intervals. The trial lasted 4 months. During this time, the number of thrips in the three central plants of each repetition, the presence of symptoms compatible with TSWV, as well as the number of fruits, and their weight, length, width and health were monitored weekly. Between the fourth and sixth weeks after the last application, a significant reduction in the population of total thrips (nymphs + + adults) was observed in both treatments B and BC compared to T and TC. In addition, plants with symptoms compatible with TSWV were very scarce, and the fruits showed significant differences in their quality parameters, producing the longest and heaviest in the BC treatment. The results showed that combining biological and cultural control makes sustainable pepper production possible.","PeriodicalId":16848,"journal":{"name":"Journal of Plant Protection Research","volume":"49 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of DsMV was confirmed by transmission electron microscopy (TEM) and reverse transcription polymerase chain reaction (RT-PCR) with specific, diagnostic primers in three out of ten examined plants. To obtain full-length sequences of CP , two pairs of primers were designed and used in the RT-PCR. The specificity of obtained products was confirmed by Sanger sequencing. The obtained sequences of CP were compared with 44 other DsMV sequences retrieved from the GenBank. Analyses revealed that DsMV population is very diverse. The variability of DsMV isolates was confirmed by low sequence identity and pervasive recombination events. The phylogenetic analysis was performed based on 37 non-recombinant CP sequences. The maximum-likelihood reconstruction revealed that the Polish isolates are distinct and grouped separately from other DsMV isolates. Due to the high genetic diversity, detecting the virus could be difficult. Nonetheless disease management relies strongly on a fast and accurate identification of the causal agent.

The results indicated a significant reduction in the conidial densities of Foc4 which was from 10 6 spores · ml –1 to a maximum of 10 1.3 spores · ml –1 and depended on the concentration of components in the input flow. Eventually the EFS produced from the lowest one was chosen to treat banana plantlets. Greenhouse experiments gave contra-dictory results of inoculated plantlets irrigated with or without EFS. The untreated banana plantlets virtually showed symptoms of infection such as discoloration of cross-cut corms, rapid wilting and dying within 60 days, while the treated ones kept their shapes and grew normally. The drastic fall in the microbial population in the rhizosphere of treated plants confirmed the activity of oxidation agents which is the major mechanism of disease suppression.
