The natural and climatic conditions of Belarusare favorable for development of over 300 species of weeds. Currently, perennial, wintering, winter and spring weeds dominate among grain crops. When grain crops are infested with both annual and perennial dicotyledonous weeds, herbicides containing several active substances are efficient. One of such promising herbicides is the new herbicide Secator Plus, MD(2.4 acid, 433 g/l + iodosulfuron, 62.5 g/l + amidosulfuron, 25 g/l + mefenpyr /antidote/, 62.5 g/l). This herbicide used at the rate of 0.3-0.5 l/ha for winter grain crops provided high biological efficiency against the dominant annual and some perennial dicotyledonous weeds (80–100% loss): Chenopodium album L., Capsella bursa-pastoris (L.) Medik., Galeopsis tetrahit L., Tripleurospermum inodorum Sch.-Bip., Galium aparine L., Sonchus arvensis L., etc. In the studied crops, reliable increases in preserved grain yield were obtained. Economic benefit: the net income in winter wheat crops amounted to 60.0-90.0 dollars/ha, winter triticale 35.5-43.7 dollars/ha, and spring wheat 159.9-212.3 dollars/ha. Based on the research results, the herbicide Secator Plus, MD is registered in the State Register of Plant Protection Products (pesticides) and fertilizers permitted for use on the territory of theRepublic ofBelarus. The research results are of interest in the field of herbology, since they reveal the mechanisms of interaction of various active substances in herbicide, show possibilities of its widespread use in agriculture.

Узагальнено особливості формувань чисельності шкідників при застосуванні сумішей добрив і засобів захисту рослин на посівах пшениці озимої. Уточнено біологію, поширення, розвиток, еколого-економічне значення шкідників у технологіях вирощування зернових культур і рекомендовані заходи щодо оптимального застосування профілактичних і спеціальних захисних заходів від шкідників у короткоротаційних польових сівозмінах. Теоретично обґрунтовано та експериментально підтверджено закономірності формувань енотмокомплексів при сучасному застосуванні рідких форм добрив, зокрема карбамідно-аміачної суміші (КАС) і засобів захисту рослин. The article generalizes the features of the formation of pest numbers when using mixtures of fertilizers and plant protection products on winter wheat crops. The specified biology, distribution, development, ecological and economic importance of pests in technologies of growing grain crops and recommended measures for the optimal use of preventive and special protective measures against pests in short-rotation field crop rotations. The regularities of the formation of enotmocomplexes in the modern application of liquid forms of fertilizers, in particular the carbamide-ammonium mixture of CAS and plant protection products, are theoretically substantiated and experimentally confirmed. The use of modern liquid forms of fertilizers KAS, 32 % and plant protection products for the cultivation of winter wheat and other cereals in the Forest-Steppe of Ukraine remains at a relatively low level: imperfection of technology, adverse climatic conditions, various stresses do not allow realizing the potential of crop productivity. The rationale for the effectiveness of such mixtures for breeding and the number of pests in modern technologies for growing crops deserves special attention in terms of optimizing the phytosanitary state of grain crops in the Forest-Steppe of Ukraine. It has been established that the best conditions for the formation of the winter wheat seed crop are created by applying fertilizers at a dose of H90 P40 and integrated plant protection. With high soil moisture and protection of plants from the pest complex, the tank mixtures are crushed, including at low moisture reserves and without plant protection, single and fragmented application of mineral fertilizers provide practically the same yield of winter wheat seeds. The relevance of the topic is due to the need to improve the effectiveness of plant protection products in mixtures of rare forms of fertilizers with the determination of their effect on the dynamics of numbers and reproduction of pests of grain crops in modern crop rotation of the Forest-Steppe of Ukraine.

The safety assessment of chemicals added or found in food has traditionally made use of data from in vivo studies performed on experimental animals. The nature and amount of data required to carry out a risk assessment is generally stipulated either in the different food legislations or in sectoral guidance documents. However, there are still cases where no or only limited experimental data are available or not specified by law, for example for contaminants or for some minor metabolites from active substances in plant protection products. For such cases, the Threshold of Toxicological Concern (TTC) can be applied. This review explores the use of the TTC approach in food safety in the European Union, in relation to the different food sectors, legal requirements and future opportunities.

According to the results of research on the phytosanitary status of rapeseed on ordinary Chernozem of the forest-steppe zone of the Akmola region, the species composition of pests was determined. Danadim power, Zolone 35% KE, Decis Expert were used against pests of this rapeseed. Indicators of biological effectiveness in the use of insecticides against pests ranged from 78-95%.The article discusses the biological and economic effectiveness of insecticides used against the main pests of rapeseed. Treatment of cruciferous rape beetle, rapeseed sawfly and cruciferous bug with Decis Expert insecticide (0.075 l/ha) showed high efficiency during the growing season. The use of plant protection products against a complex of harmful organisms showed that, depending on the prevailing climatic conditions, the yield increased to 1.3 c/ha, and the maximum - to 1.9 c/ha. Thus, according to the biological effectiveness of insecticides used against pests, the productDecis Expert showed high results in all pests. On the Cruciferous rape beetle it was 85.7%, in the turnip sawfly – 93.5%, in the cruciferous bug – 81.9%.

The installation of a permanent ground cover in vineyards offers numerous agronomic (soil protection, soil fertility) and environmental (reduced leaching of nutrients and of plant protection products, reduced use of herbicides, biodiversity) benefits. Nevertheless, such ground covers are not always free of drawbacks (competition for water and nitrogen, increased risk of frost, management). For the growers, the challenge is to manage the green ground covers in such a way as to preserve their advantages while limiting these drawbacks. Among the tools available to the winegrower is the sowing of a seed mixture composed of selected species: a choice depending of the soil and climatic conditions of the parcel, but also of the different, and sometime contradictory, objectives of the grower. This paper lists the agronomic and environmental issues addressed by the installation of a permanent ground cover in vineyards. It describes two concrete situations – ground cover for vineyards integrated in agro-ecological networks and green cover on the row of vines (as alternative to glyphosate) – for which, according to the objectives and the impacts, a choice of plant species is proposed. At last, it presents the trials now carried out to validate and optimize those selections, as well as the first observations and results gathered to date.
