Opis:: Basic Substances are a newly effective category of Plant Protection Product under EC Regulation No 1107/2009. The first approved application of Equisetum arvense L. opened Part C of Implementing Regulation (EU) No 540/2011, which lists the basic substance approved. Although E. arvense was described as a fungicide extract, subsequent applications like chitosan were related to non-biocide molecules. Consequently, plant protection product data were collected from research on alternative or traditional crop protection methods. They are notably issued or derived from foodstuffs (plants, plant by-products, plant derived products, substances and derived substances from animal origin). Applications are currently submitted by our Institute, under evaluation at different stages of the approval process or already approved. Remarkably, this Basic Substance category under pesticide EU Regulation was surprisingly designed for these non-biocidal plant protection products. In fact, components described as the “active substance” of most of the actual applications are food products like sugars and lecithin. Basic Substance applications for these foodstuffs are therefore a straightforward way of easily gaining approval for them. Here we describe the approval context and detail the agricultural uses of theses food products as Biological Control Agents (BCAs) or biorationals for crop protection. From all deposited or approved Basic Substance Application (BSA), a proof has been provided that non-biocide and food products via physical barrier or lure effects may be effective plant protection products with an acceptable low profile of concern for public and agricultural safety.

Opis:: Rhizomania is one of the most important diseases of sugar beet around the world – including in Iran. The disease causes a severe decrease in sugar yield and is a limiting factor in sugar beet cultivation. Control of the disease is very difficult due to the long-term survival of its fungal vector (Polymyxa betae) in the soil. In this study, we investigated the effects of antagonistic fungal isolates on the population of the resting structure (cystosorus) of P. betae, under greenhouse conditions. Antagonistic fungi, including Trichoderma harzianum and Talaromyces flavus, were isolated from soil samples collected from sugar beet infested fields in the Semnan Province of Iran. In the next step, their inocula were prepared through reproduction on rice bran. For evaluation of the efficacy of antagonists in greenhouse conditions, a split plot trial was conducted and performed. The main factor was three different methods of application of T. flavus as the soil treatment, seed treatment, and a combination of both methods. The sub-factor was the use of different fungal isolates. To determine the cystosorus population of the fungal vector, seedling roots in all treatments were stained with lactic acid and fuchsine (lactofushine), 60 days after sowing. The number of cystosorus in one gram of root was counted using a light microscope and hemocytometer. At the end of the study, average root weight in different treatments was also measured to select and introduce the best treatments in regard to their effects on root weight. According to the results, the number of cystosorus in 1 g of root was different in various treatments and those treatments containing TF-Su-M-1, TF-Su-M-2, TH-Su-M-1, and TH-Su-M-2 used as a soil application method were more effective in the reduction of the cystosorus population and root weight increase. Among the above-mentioned treatments, maximum reduction of cystosori population and the increase in root weight were observed in TH-Su-M-1 and TF-Su-M-2 through the soil application method.

Opis:: Biocontrol of plant diseases has emerged as an eco-friendly measure of plant protection and has experienced a lot of devotion in the last two decades. Biocontrol agents include application of microbial agents, their secretion products and natural extracts from different parts of several plants. The present study, therefore, aimed at evaluating the potency of aqueous extracts of Tagetes erecta L. (marigold) in controlling bacterial speck disease in tomato plants. The experimental design consisted of two groups of 50 plants each: group 1 – sprayed with sterile water (control); and group 2 – sprayed with marigold extract. Spraying was performed under aseptic conditions at the third node from the base of each plant. Challenge inoculation with the bacterial speck pathogen Pseudomonas syringae pv. tomato was performed to analyze the disease severity on the test plants. The parameters of study were analysis of alteration in the activity and gene expression of peroxidase (POX), phenyl ammonia lyase (PAL), and polyphenol oxidase (PPO), as well as isoform expression of POX and PPO. The results demonstrated strong inductive effects of the extract on the activity and genes of POX, PAL and PPO. De novo expression of POX and PPO isoforms following marigold extract treatment was also observed. The observations indicate that marigold extract could be a promising biopesticide.

Tytuł:: Effect of the alternative host Strophosoma faber [Herbst] on efficacy of the entomopathogenic nematode Steinernema glaseri in control of Amphimallon solstitiale grubs in the soil

Opis:: Larvae of June chafer (Amphimallon solstitiale L.) are important pests of the turf-grass. During a routine field collection of A. solstitiale grubs numerous larvae of a curculionid, Strophosoma faber were frequently observed in the soil. Bath insects shared the same environment in the same season. Since entomopathogenic nematodes are considered as candidates for control of A. solstitiale it was decided to examine the effect of concurent presence of S. faber on the efficacy of S. glaseri. The laboratory test revealed that both insects were infected by S. glaseri. In conclusion, could be support the suggestion that S. faber is probably most susceptible for entomopa-thogenic nematodes and could become the alternative host for them.
Larwy guniaka czerwczyka (Amphimallon solstitiale L.) są szkodnikami terenów trawiastych i przyczyną poważnych szkód ekonomicznych. W trakcie dokonywania cyklicznych zbiorów pędraków tego szkodnika zaobserwowano licznie występujące w glebie larwy ryjkowca Strophosoma faber (Herbst). Oba gatunki zasiedlały w tym samym czasie tę samą niszę ekologiczną. W związku z tym, że nicienie owadobójcze są rozważane jako czynnik biologicznego zwalczania guniaka czerwczyka, szkodnika występującego na zielonych terenach zurbanizowanych, podjęto decyzję o przeprowadzeniu testów laboratoryjnych, w trakcie których oceniono wpływ obecności konkurencyjnego gospodarza na skuteczność zastosowanych nicieni przeciwko innemu szkodnikowi. Stwierdzono, że oba gatunki są infekowane przez nicienie, choć zdecydowanie wyższy poziom śmiertelności zaobserwowano dla larw ryjkowca. Można uznać, że S. faber jest bardziej wrażliwym owadem niż A. solstitiale na infekcje spowodowane przez nicienie owadobójcze. Tym samym może stać się dla nich gospodarzem alternatywnym i rezerwuarem dla następnych pokoleń larw infekcyjnych S. glaseri.

Opis:: Achieving high quality propagative material is difficult today due to the limited number of pesticides recommended for use. Simultaneously, EU regulations on Integrated Pest Management (IPM) in forest nurseries came into a force, requiring a search for alternative plant protection methods that are safe for humans, animals and the environment. In this paper, we present the possibilities of using bio-fungicides against diseases in forest nurseries, their mechanisms of action, as well as the direction of their development (according to IPM rules). We reviewed the results achieved by different research teams presenting the possibilities and trends in combatting Oomycetes and Fusarium spp. pathogens currently having the most important economic impact.
