Influence of fungicide compositions on efficiency of Fusarium species control and winter wheat productivity

Goal. To determine the effectiveness of promising fungicide compositions for controlling the pathogens of fusariosis in seed treatment and their effect on the productivity of winter wheat. Methods. Field, against the background of artificial infection Fusarium spp. The preparations were used in the treatment of winter wheat seeds of the Smuglyanka variety (BBCH 00) before sowing, and also during the flowering period — VVSN51. Statistical processing of research results was performed by analysis of variance using Excel. Results. For prolonged protection of the zone of the root system of seedlings of plants, the effectiveness of treating compositions was studied, which include components with a low level of metabolism and apical transport, as well as fungicidal treating agents — derivatives of the class of triazoles, imidazoles, benzimidazoles, second-generation succinate dehydrogenase inhibitors and phenylpyrroles with insecticidal protectants. It has been established that for seed treatment, the use of fludioxonil-based preparations is effective. The level of control of Fusarium pathogens increased with the introduction of a composition of fludioxonil with sedaxan and insecticidal components. Tebuconazole and compositions of tebuconazole with prothioconazole and diphenoconazole are effective for controlling spike fusarium. Conclusions. The most reliable protection of crops from Fusarium infections is the formation of agrophytocenosis with a low level of infectious background due to the reduction in the rotation of the areas of donor crops Fusarium spp. Minimization of soil cultivation contributes to the spread of pathogens of Fusarium. The key elements for obtaining healthy sowing are the introduction of cultivar-resistant varieties and hybrids resistant to Fusarium spp. And the use of highly effective fungicides and their compositions, including succinate dehydrogenase inhibitors, with insecticides during the growing season.

Predominant Pathogen

Fusarium crown rot of wheat has become more prevalent in China. To investigate the phylogenetic structure of Fusarium causing wheat crown rot in China, wheat basal stems with symptoms of the disease were collected from 2009 to 2013 in Jiangsu, Anhui, Henan, Hebei, and Shandong provinces. In total, 175 Fusarium isolates were collected and their mycotoxin chemotypes and distribution were identified. Among the 175 isolates, 123 were Fusarium asiaticum; 95 of these were the chemotype 3-acetyl-deoxynivalenol (3-AcDON) and 28 were nivalenol (NIV). Thirty-seven isolates belonged to F. graminearum, which were all 15-AcDON. Smaller numbers of isolates consisted of F. acuminatum, F. pseudograminearum, and F. avenaceum. The virulence of F. asiaticum and F. graminearum isolates on wheat crowns and heads was comparable. The virulence of isolates of the DON and NIV chemotype were statistically similar, but DON tended to be more aggressive. The DON concentrations in grains from wheat heads inoculated with isolates causing either Fusarium head blight or crown rot were similar. In the five provinces, F. asiaticum of the 3-AcDON chemotype was the predominant pathogen causing crown rot, followed by F. graminearum. Recent changes in causal Fusarium species, chemotypes, and distribution in China are discussed.

First Time

Soybean is threatened by many pathogens that negatively affect this crop's yield and quality, e.g., different Fusarium species that cause wilting and root rot diseases. Fusarium root rot (FRR) in soybean can be caused by F. graminearum and other Fusarium spp. that are associated with Fusarium head blight (FHB) in cereals. Therefore, it was important to enquire whether Fusarium pathogens from soybean can cause disease in wheat, and vice versa. Here, we investigated the Fusarium root rot complex in Manitoba (Canada) from symptomatic plants, using both culture- and molecular-based methods. We developed a molecular diagnostic toolkit to detect and differentiate between several Fusarium spp. involved in FHB and FRR, then we evaluated cross-pathogenicity of selected Fusarium isolates collected from soybean and wheat, and the results indicate that isolates recovered from one host can infect the other host. Trichothecene production by selected Fusarium spp. was also analyzed chemically using LC-MS in both soybean (root) and wheat (spike) tissues. Trichothecenes were also analyzed in soybean seeds from plants with FRR to check the potentiality of trichothecene translocation from infected roots to the seeds. All of the tested Fusarium isolates were capable of producing trichothecenes in wheat spikes and soybean roots, but no trichothecenes were detected in soybean seeds. This study provided evidence, for the first time, that trichothecenes were produced by several Fusarium spp. (F. cerealis, F. culmorum and F. sporotrichioides) during FRR development in soybean.

The purpose of the study was to scientifically substantiate the effectiveness of polishans and Macroshans as elements of the technology of winter wheat cultivation in the conditions of the Central forest-steppe, their effect on productivity and product quality. Experiments, observations, records, and analyses were carried out using the field experience methodology [6]. Statistical processing of the results was performed using methods of analysis of variance. Treatment of seeds with Polishans at a dose of 0.2 l / t promoted the growth and development of winter wheat plants on all backgrounds of fertilizer application - N45P45K45 and N90P90K90, and without applying the main fertilizer. Seed treatment with Palisander and processing plants Microsensor plant height of winter wheat increased on the background without fertilizers by 3.2 cm (4,5%), against making N90P90K90 - 2.7 cm (3.5%), and in the background making N45P45K45 - 4.2 cm (5.5 %). When treating seeds with Polishance, the coefficient of productive bushiness of plants was 1.94 on the background without fertilizers and tended to increase on the studied backgrounds of fertilizer 1.97-2.01. The yield of winter wheat in the studies was affected by the lack of available moisture for the formation of reproductive organs. At the same time, the effect of both macrofertilizers and microfertilizers, depending on the time of their application, on the yield of winter wheat was very clearly traced. The highest productivity of winter wheat was obtained with the following complex of studied agricultural methods: seed treatment with Polishans (0.2 l / t) + treatment of crops with Macrochance (0.25 l / ha) twice during the growing season-tillering and earing and all this against the background of the main fertilizer N90P90K90. The use of the Macrochance polymicrobial increased the gluten content by 2-4% while increasing the IDC index to 65-74 units, which corresponded to the I quality group.

В статті розглядаються особливості застосування стимуляторів росту компанії «Soil-Biotics» (США) як приклад комплексного використання гуматів для підвищення рівня врожайності пшениці озимої. Доведено, що норми та способи використання гуматів для передпосівної обробки насіння та внесення в ґрунт сприяють кращому формуванню елементів структури врожайності, в першу чергу продуктивного кущіння. Статистична обробка методом багатофакторного дисперсійного аналізу засвідчила, що варіанти, де використовувалася передпосівна обробка насіння препаратом «1R Seed treatment» в нормі 3 кг/т та вносився в ґрунт «5R SoilBoost EA» в нормі 30 кг/га, значно перевищували контроль за кількістю рослин, які краще перезимували та продуктивністю. Аналіз впливу гумінових препаратів на формування ознак продуктивності показує, що внаслідок передпосівної обробки насіння та внесення під час сівби гумінового препарату «5R SoilBoost EA» продуктивне кущіння збільшується майже на 37 %. Інші ознаки реагують на застосування препаратів менше – кількість зерен в колосі зросла на 7,3 %, а маса зерна з колоса – на 5,5 %. Проте така різниця була статистично достовірною порівняно з контрольними варіантами. Маса 1000 зерен при цьому залишалася фактично незмінною – статистично достовірної різниці між варіантами не було. The article discusses the features of the use of growth stimulators by Soil-Biotics (USA) as an example of the integrated use of humates to improve the yield of winter wheat. It is proved that the norms and methods of using humates for presowing seed treatment and introduction into the soil contribute to a better formation of the elements of the yield structure, primarily productive tillering. Statistical processing by the method of multivariate analysis of variance showed that the variants in which presowing seed treatment with 1R Seed treatment was applied at a rate of 3 kg / t and applied to the soil 5R SoilBoost EA in the norm of 30 kg / ha, significantly exceeded the control by the number of plants , which were better wintered and productive. Analysis of the effect of humic preparations on the formation of signs of productivity shows that as a result of presowing seed treatment and application of humic preparation 5R SoilBoost EA during sowing, productive tillering increases by almost 37%. Other signs respond to the use of drugs less - the number of grains in the ear increased by 7.3%, and the mass of grain from the ear - by 5.5%. However, this difference was statistically significant compared to the control options. The mass of 1000 grains remained virtually unchanged - there was no statistically significant difference between the variants.

Isolated Species

The frequency of fungi and mycotoxin concentrations of deoxynivalenol (DON) and zearalenone (ZON) were studied in winter wheat grains harvested in 2009. The most frequently isolated species belonged to genera Alternaria (81.55%) and Fusarium (12%), followed by Rhizopus spp. (3.75%), Acremoniella spp. (1.15%) and other fungi (Acremonium spp., Arthrinium spp., Aspergillus spp., Bipolaris spp., Chaetomium spp., Nigrospora spp., Penicillium spp. and Ramichloridium spp.) isolated in less than 1%. The following species of the genus Fusarium were identified: F. graminearum (82.50%), F. sporotrichioides (5.42%), F. proliferatum (4.17%), F. subglutinans (4.17%), F. poae (1.66%), F. semitectum (1.25%), and F. verticillioides (0.83%). In 100% of wheat grain samples DON was detected (110-1200 ?g kg-1, average 490 ?g kg-1), while ZON was detected in 10% of samples and in the lower average of 70 ?g kg-1 with the limit values ranging from 60 to 80 ?g kg-1. Statistically significant positive correlations were established between the concentration of ZON with the frequency of F. graminearum (r = 0.63) or with the frequency of Fusarium spp. (r = 0.58). A negative insignificant correlation was determined between the DON level and the percentage of present Fusarium species.
