Opis:
The composting process is a natural method of waste disposal. Decomposition of organic matter occur with the participation of various groups of microorganisms. Using glyphosate-based herbicides aims to reduce agricultural losses. Biodegradation of glyphosate in soil is obtain with bacteria and fungi and may affect their functioning. The purpose of this study was evaluating the effects of glyphosate on bacterial diversity during composting and to monitor potential changes in community structure and species abundance. The addition of glyphosate did not affect the morphology of the tested groups of bacteria and did not cause changes in the morphological structure of fungi. Sampling after 10 minutes, 24 hours, 48 hours and 72 hours showed that the abundance of bacterial colonies changed over time compared to the control groups. However, the results suggest that the addition of glyphosate is insufficient to influence the composting process, thus disturbing the specific biocenosis.

Opis:
At a global scale, biological invasions represent one of the most important threats to biodiversity conservation. The Carpobrotus (Aizoaceae) genus, which is native to South Africa, has been introduced into five different continents and is particularly invasive in many coastal habitats. The application of glyphosate avoids some problems associated with manually controlling Carpobrotus over large spatial scales. However, before this practice can be extended and its impact minimized, its effectiveness under different application conditions must be assessed first. Thus, glyphosate was sprayed at different concentrations (0.5, 0.4, 0.3, 0.2, 0.1, and 0.05 g/m2) on experimental plots with 100% Carpobrotus coverage to determine the minimum effective dose. Tarping was also evaluated as an alternative method for Carpobrotus management over reduced areas. Thus, four different weed-control fabric types were tested: black anti-weed fabric, sewn felt, black G-300 polyethylene, and Fijavert coconut-anti-weed matting on experimental plots with 100% Carpobrotus coverage. The obtained results showed that the minimum effective dose of glyphosate which prevents Carpobrotus regrowth in dune ecosystems was 0.4 g/m2. It was also shown that at least three months of tarping were required under winter conditions to produce complete Carpobrotus plant wilting and thus, prevent their regrowth. No significant effect on Carpobrotus growth was observed in terms of the fabric type used for the tarping tests. The presence of native species seedlings in the experimental plots after the death of the Carpobrotus plants following the application of herbicides or tarping was also monitored.

Opis:
The experiment was carried out on the experimental field of the National Institute of Horticultural Research in Skierniewice in 2014 to evaluate the biological effect of herbicides on carrot. The following treatments were used: herbicide clomazone (120 g·ha-1) and its mixture with pendimethalin (90 + 999 g·ha-1), used without and with the soil adjuvant Grounded (0.4 l·ha-1). Clomazone with adjuvant was applied at rates of 96 and 120 g·ha-1, and the mixture of clomazone with pendimethalin at rates of 60 + 666 and 90 + 999 g·ha-1. The herbicides were applied directly after the carrot sowing. The experiment assessed weed control, secondary weed infestation as well as growth, development and yielding of carrot. Clomazone and its mixture with pendimethalin, used without and with the soil adjuvant Grounded, effectively reduced weed infestation and did not cause phytotoxicity on carrot plants. The beneficial effects of the soil adjuvant Grounded on the mixture of clomazone and pendimethalin were observed.

Opis:
Background. The chemical weed control method plays a fundamental role in clean cultivation of white lupine. However, due to the threats caused by the active substances of herbicides in the natural environment, safer methods of weed control for white lupine plants should be sought. Among others, through the possibility of using in-soil herbicides in reduced doses. Material and methods. A field experiment was carried out in the years 2014–2015, to evaluate the effect of herbicide mixture Dispersive Afalon 450 SC and Command 480 EC (contain linuron and clomazone), applied in various doses, on weed control and yield of white lupine. Results. Application of in-soil herbicide mixture Dispersive Afalon 450 SC (linuron) + Command 480 EC (clomazone) in a mention the applied dose and a reduced by 25% dose decreased weed number and mass, as well as weed species diversity, which was reflected in an increased white lupine seed yield. In the experiment, no harmful phytotoxic effect of the applied doses of herbicides containing linuron and clomazone on the emerging plants of white lupine cultivar Butan was found. Conclusion. Doses of herbicide mixtures containing linuron and clomazone decreased by 25% made it possible to obtain relatively less weed infestation and provide a high level of white lupine seed yield. Dose reduction of the tested herbicides by 50% significantly affected the growth and yield conditions of white lupine.
W jednoczynnikowym doświadczeniu polowym zrealizowanym w latach 2014–2015 badano wpływ zróżnicowanych dawek mieszanin herbicydów zawierających linuron (Afalon Dyspersyjny 450 SC) i chlomazon (Command 480 EC) na zachwaszczenie i plonowanie łubinu białego. Stwierdzono, że aplikacja mieszaniny herbicydów doglebowych Afalon Dyspersyjny 450 SC (linuron) + Command 480 EC (chlomazon) w dawkach pełnej i zredukowanej o 25% zmniejszyła w porównaniu z obiektem kontrolnym liczbę i masę chwastów oraz ich różnorodność gatunkową, co znalazło odzwierciedlenie w zwiększeniu plonu nasion łubinu białego. Nie stwierdzono szkodliwego fitotoksycznego oddziaływania aplikowanych dawek herbicydów zawierających linuron i chlomazon na wschodzące rośliny łubinu białego odmiany Butan. Obniżone o 25% dawki mieszaniny herbicydów zawierającej linuron i chlomazon pozwalają utrzymać stosunkowo małe zachwaszczenie i zapewnić wysoki poziom plonu nasion łubinu białego. Redukcja dawek testowanych herbicydów o 50% zwiększa istotnie zagrożenie dla warunków wzrostu i plonowania łubinu białego.

Opis:
Redroot pigweed (Amaranthus retroflexus L). is a broadleaf weed in autumn crop fields in Russia. Four field experiments were performed in Stalskiy region, southern Russia in two growing seasons, 2016 and 2017, to investigate the effects of postemergence applications of applied alone or in tank mixtures in winter wheat cultivars Tanya and Bagrat. Redroot pigweed control was greatest with tribenuron and all herbicide treatments containing tribenuron. The lowest redroot pigweed control was with aminopyralid/florasulam (study 1) and triasulfuron (study 2), respectively, whereas redroot pigweed had intermediate responses to the other examined herbicides. Tribenuron plus fluroxypyr sprayed on wheat cultivar ‘Tanya’, and tribenuron plus triasulfuron on wheat cultivar ‘Bagrat’ resulted in increased wheat grain yields. Overall, tribenuron and herbicides containing tribenuron provided the most efficient redroot pigweed control compared with the other herbicides and consistently maintained optimal winter wheat yields. Tribenuron could ameliorate redroot resistance to herbicides in wheat fields in southern Russia.

New solutions which would allow for the realization of two basic objectives, i.e. production-related and environmental ones, continue to be sought in plant production. Hence, the purpose of research was to define the impact of five methods of potato field treatment with the application of growth biostimulators and herbicide on the content and harvest of major protein Solanum tuberosum L. Field experiments were carried out in the years 2015-2016 in the region of Eastern Poland (52°02’N; 23°07’E). The experiment was performed in the split-plot system in three replications. The tested factors included: I. Factor – two early edible potato cultivars (Owacja, Bellarosa), II. Factor – methods of treatment with the application of growth biostimulators: GreenOk-Uniwersal Pro and Asahi SL and their combination with Avatar 293 ZC herbicide. As a result of the carried out research, it was noted that the methods of treatment applied in the experiment had a beneficial effect on the value of tested features in comparison to the control object, treated exclusively mechanically (without the use of biostimulators and herbicide). Both in terms of protein concentration and the obtained crop of major protein, the application of mechanical treatment for sprouting of potato plants and Avatar 293 ZC herbicide at a dose of 1.5 dm3∙ha-1 directly before the sprouting and subsequently post sprouting, triple application of GreenOK Universal-PRO bioactivator at the following doses: 0.10 dm3∙ha-1 + 0.15 dm3∙ha-1 + 0.15 dm3∙ha-1 was the most beneficial. The average content of major proteins in this object amounted to 8.14% while the average protein yield – 750.09 kg·ha-1.

Opis:
Weeds are one of the most important limiting factors in the production of chickpea (Cicer arietinum) in Iran, especially in autumn sown chickpea. Weed density and biomass in au- tumn chickpea are seven and two and a half times higher than the spring chickpea, respec- tively. The weed damage to chickpea in Tabriz, Kermanshah and West Azerbaijan was esti- mated at 48.3, 57 and 36%, respectively. Sixty-four weed species were identified in chickpea fields. Convolvulus arvensis L. and Galium tricornutum Dandy have the highest presence in chickpea fields. Pyridate and linuron are the only herbicides registered for use in chick- pea fields in Iran. However, research results show that fomesafen and isoxaflutole are the most appropriate herbicides for chickpea fields. Oxyfluorfen, imazethapyr, metribuzin, tri- fluralin, simazine, terbutryn and pendimethalin are the major herbicides studied in weed control research. The combination of herbicides and mechanical control is one of the effec- tive methods to reduce weeds. Hand weeding and cultivation between rows are the most effective mechanical methods of weed control. High nitrogen enhances weed dry weight. Safflower and barley residues reduce weed populations and biomass. Barley-chickpea and wheat-chickpea intercropping systems increase chickpea yield together with proper weed control. In future research, more attention should be paid to surfactants to reduce the use of herbicides, rotation crops and integrated weed management in chickpea.

Sorgo po pszenicy, kukurydzy, ryżu oraz jęczmieniu zajmuje piątą pozycję pod względem powierzchni upraw zbóż na świecie. Sorgo w początkowej fazie cechuje się powolnym wzrostem, co powoduje, że przez pewien czas międzyrzędzia pozostają niezakryte i w konsekwencji stwarza odpowiednie warunki do szybkiego wzrostu i rozwoju chwastów. Celem prowadzonych badań była ocena skuteczności i selektywności wybranych herbicydów stosowanych w uprawie sorgo na terenie Wielkopolski.
Sorghum after wheat, corn, rice and barley ranks fifth in terms of cereal area in the world. Sorghum in the initial phase is characterized by slow growth, which means that for some time the inter-glands remain uncovered and, as a consequence, creates appropriate conditions for rapid growth and development of weeds. The aim of the research was to evaluate the effectiveness and selectivity of selected herbicides used in sorghum cultivation in Wielkopolska

The experiment studied the effect of various mulching terms of ‘Foxtrot’ tulips with wheat straw in combination with spraying of plantations with herbicides using various doses and different amounts of working liquid. The mulch was laid out just after planting and after the soil had frozen. The experiment included combinations, in which the mulch was left until the end of the growing season or removed in spring. Spraying with single (linuron 675 g·ha–1 + lenacyl 1000 g·ha–1) or double herbicide dose (linuron 1350 g·ha–1 + lenacyl 2000 g·ha–1) was made before covering the soil with mulch and also on mulch – two weeks after planting the bulbs, or in the spring after thawing the soil. Volumes of 300 dm3 and 600 dm3 of working liquid were used for spraying. Tulips covered with mulch bloomed 2–3 days later and formed longer shoots as compared to non-mulched ones. The highest yield of marketable bulbs and the first-selection ones was obtained from tulips mulched immediately after planting and sprayed 2 weeks later with herbicides used in a single dose of 600 dm3 of a working liquid. Mulching of tulips after soil freezing and removal of mulch in spring adversely affects the number and weight of commercial bulbs. The lowest yield was obtained in combinations, in which the mulch was not used. The use of additional nitrogen fertilization before laying out the mulch did not affect the yield of tulips. Herbicides can be used both before mulching and after covering the plantation with mulch. It is not necessary to increase the dose of the agent and the amount of water.

Opis:
Field experiments were conducted to evaluate the efficacy of glyphosate (H1) and fluazifop-P-butyl (H2) herbicides with adjuvants on the common reed without cutting and at two different cutting levels (10 and 30 cm). The adjuvants were urea, nitric acid and sulfonic acid. The relative importance value (RIV), leaf chlorophyll content and plant density were determined to assay the efficacy of herbicides. Glyphosate treatment only (H1 a) was more effective than fluazifop-P-butyl (H2 a) on reeds without cutting and at the 10 cm cutting level. However, no significant difference was observed between them at the 30 cm cutting level. A positive effect of plant cutting occurred on the efficacy of all herbicides applied alone or in a tank mix with adjuvants. Furthermore, the 10 cm cutting level was more effective in eradication of reeds than the 30 cm cutting level. The adjuvants significantly improved the efficacy of the recommended (Hb) and half recommended (Hc) herbicide rates in comparison to being used alone on uncut reeds. The reduction percentages were 94.5, 86.99, 76.61 and 69.94 for H1 b, H1 c, H2 b and H2 c treatments, respectively. However, the adjuvants did not improve the glyphosate effect at different levels of cutting. Conversely the reduction percentage of reeds was improved by the recommended rate of fluazifop-P-butyl with adjuvants (H2 b) to 92.77% and 84.62% at 10 and 30 cm cutting levels, respectively.

Opis:
Two field experimental trials were carried out in central Italy, in 2005 and 2006, on biomass sorghum [Sorghum bicolor (L.) Moench] in order to assess weed control efficacy and selectivity to the crop of some pre- and post-emergence herbicides applied at different doses and in different mixtures. All herbicides showed good selectivity to the crop, although postemergence treatments showed higher transitory phytotoxicity effects than pre-emergence treatments, especially when high temperatures occurred after treatments, decreasing the selectivity of leaf herbicides (i.e. MCPA, 2,4-D, bromoxynil and dicamba). Considering pre-emergence applications, terbuthylazine alone against broadleaves or in mixtures at low doses with s-metolachlor against mixed infestations (grasses + broadleaves), seemed to be the best options to obtain a good selectivity to the sorghum and a high weed control level. Aclonifen showed some limits in terms of weed spectrum and could be recommended only against simplified broadleaf weed infestations without the presence of less susceptible weeds, like Amaranthus retroflexus, Portulaca oleracea and Solanum nigrum. Propachlor seemed not to be advisable due to the low efficacy against all the major broadleaf warmseason weed species in the Mediterranean areas. Considering post-emergence applications, all treatments gave quite similar results in terms of weed control, although, the mixture of terbuthylazine + bromoxynil seemed to be the best option due to bromoxinil’s higher efficacy than other foliar herbicides, such as MCPA, 2,4-D and dicamba, which can increase the efficacy of terbuthylazine alone especially under dry weather conditions. There were no significant differences in sorghum biomass between herbicide treatments, although, the more selective pre-emergence treatments showed, on average, a higher biomass yield value than the less selective post-emergence treatments. For these reasons, biomass values seemed to be more related to herbicide selectivity than to herbicide efficacy, especially in cases of scarce competitiveness of weed flora.
