Authors: Tkalich Yu. , Shevchenko S. 
Published: May 2020

Goal. The of the research was to conduct field studies of new formulations of herbicides in winter wheat crops and to optimize the phytotoxic composition of tank mixtures consisting of different-spectrum active substances.
Methods. In carrying out the work, general scientific and special research methods were used.
Results. Species diagnostics of weed phytocenoses in winter wheat crops showed that high potential weed caused dominance in the agrophytocenoses of ragweed wormwood and sunflower scavenger. The deformation of the classic wintering type of weed was observed in the direction of the annual seed species composition. The phytotoxic properties of tank mixtures of Granstar Gold and Hammer herbicides and combined preparations were studied, their technical efficiency, the dynamics of depression and the death of weeds during the growing season were established, the individual resistance of certain types of weeds was revealed. A biometric analysis (crop density, linear growth, grain yield from an ear) of winter wheat was carried out depending on the toxicity of the herbicides. The scientific conclusion was made that the most effective mixture of herbicides was Granstar Gold 30 g/ha + Hammer 20 g/ha.
Conclusions. As a result of the studies, it was found that winter wheat responded positively to reducing the degree of clogging by improving biometric and productive indicators. The yield of winter wheat grain is in a natural dependence on the degree of weediness of crops and phytotoxic effectiveness against weeds. The maximum increase in grain yield of 0.34 t/ha was achieved in comparison with the control when processing wheat crops of the winter mixture of herbicides Granstar Gold 30 g/ha + Hammer 20 g/ha.

Authors: Auskalniene O. , Zadorozhnyi V. 
Published: May 2020

Goal. Check the resistance of populations of Apera spica-venti (L.) P. Beauv. to herbicides from the class of inhibitors acetolactate that are used in crops of winter wheat.
Methods. Field and laboratory studies. Visually evaluated the treatment efficacy 4 weeks after application (WAT4). Visible symptoms on the surviving plants were considered in percentage (0% — no survival, 100% plants without visible damage) to the raw options of the same population.
Results. Among the tested populations of A. spica-venti resistant to herbicides from the class of inhibitors acetolactate not detected. In all regions of Ukraine, where selected seed samples, there were repeated crops of winter wheat, and was the precursor of the culture of sunflower, soybean, lupin, etc., for control of weeds in crops which were applied the herbicides with a different mechanism of action. The reason for the low efficiency of herbicides in crops of winter wheat could be low rates of application, weather conditions, other factors associated with the technology application of herbicides.
Conclusions. Ukraine has not confirmed the resistance of Apera spica-venti (L.) P. Beauv. to the action of herbicides from the class of inhibitors acetolactate, which takes place in Lithuania. Primarily due to differences in the technologies of cultivation of winter wheat, particularly in rotations. In Ukraine, information about the presence in crops of resistant biotypes of weeds are quite limited. To prevent resistance it is necessary to conduct herbological monitoring of major crops considering the experience of countries where this problem is becoming more acute, to develop measures to prevent it.
Reliable protection of lentils against weeds
Authors: Riznyk V. 
Published: May 2020

Goal. To identify the features of the infestation of crops of lentils and improve on this basis, the elements of chemical protection from adverse impact of weeds.
Methods. Field experiments were laid out in 2016—2019 according to the scheme: 1. Clogged control. 2. “Clean” control. 3. Gesagard 500 WF + Panther 4%, K. E. (3 l/ ha + 1 l/ ha). 4. Zenkor 70 WG + Targa Super, k.e. (0.6 l/ ha + 1.0 l/ ha). 5. Stomp 330, k.e. + FUSILADE Forte 150 EC, k.e. (3.0 l/ ha + 0.7 l/ ha).
Results. The contamination of crops of lentils in the years of research had mixed. As a result of pre-release areas from the presence of perennial plants (couch grass, convolvulus arvensis) weeds, mostly introduced annual grasses and dicotyledonous species. The most widespread in crops were plants of foxtail glaucous — 19.5 pieces/ m2 (22.5% in the structure of impurity), Echinochloa ordinary and 17.3 (19.9%), amaranth thrown back to 10.7 (12.3%), nightshade black — 6,8 pieces/ m2 (7.8%). In General, the time of counts (end of III decade of may) the number of weeds was 86.7 pieces/ m2. Use for protection of lentil combinations of herbicides of soil action of Gezagard 500 FW, k.s. (3.0 l/ ha) and graminicide Panther, 4% k.e. (1.0 l/ ha) reduced the ability of those present in the crops of weeds to form their mass. In average per years of research, the mass of weeds in crops of version 3 testing amounted to a total of 388 g/ m2 or 13.6% of the weedy control. Herbicides provided the reduction of the mass of weeds in 86.4%.
Conclusions. In terms of the use of herbicides of Gezagard 500 FW, k.s. (3.0 l/ ha) + Panther, 4% k.e. (1.0 l/ ha) received an average of 1.49 t/ ha of seeds, or 83.7% of the maximum in the testing of the level of harvest. Much more effective was the use Zenkor 70 WG, v.g. (0.6 l/ ha) Targa Super 5% k.e. (1.0 l/ ha) and stomp 330, k.e. (3.0 l/ ha) + FUSILADE Forte 15% k.e. (0.7 l/ ha), which provided the formation of 1.61 and 1.56 t/ ha of seeds, 90.4 and 87.6% of the “clean” control, respectively.

Authors: Klechkovskіy Y. , Mogilyuk N. 
Published: May 2020

Goal. The effectiveness of the herbicides Hurricane Forte 500 SL, RK and Bast 150 SL, RK in protecting the apple orchard from ragweed was evaluated.
Methods. The studies were conducted in the field in plantations of apple trees. The soil of the experimental plot is the southern light loamy chernozem, with a humus content in the arable layer of 3.2%, pH — 7.1. The tree planting scheme was 1.5—4 m. The experiments, observations, and counting were carried out according to generally accepted methods.
Results. According to the results of phytosanitary surveys of apple plantations in farms of Odessa region, 27 species of weeds were identified, which belong to 12 botanical families. Among the annual weeds, the following species dominated: ragweed, ragweed, common shrubbery, common bedroot, white gauze; from perennial species: sharp gusset, pink sow thistle, field bindweed, wheat grass creeping, spurge vine. The mass emergence of seedlings of ragweed was observed in the third decade of April — the first decade of May. The phase of development of ragweed plants at the time of processing was 2—4 true leaves. Herbicide Hurricane Forte 500 SL in the norm of 2.0 l/ ha a month after treatment controlled 98.0%, at the end of the growing season — 83.2% of the weed. The treatment of plots with Hurricane Forte 500 SL with a flow rate of 1.0 l/ha and the addition of Trend 90 surfactant to the working solution ensured weed control after a month — 96.8%, at the end of the growing season — 80.6%. With a single application of the Bast 150 SL herbicide at a consumption rate of 4.0 l/ha, the technical efficiency a month after treatment was 94.7%; at the end of the growing season, it decreased to 60.1% due to the regrowth of ragweed plants. Two-time use of the Basta 150 SL preparation at a consumption rate of 3.0 l/ha made it possible to control the weed during the entire growing season at the level of 86.4—87.4%.
Conclusions. The use of a reduced consumption rate of the Hurricane Forte 500 SL, RK herbicide in a mixture with the surfactant Trend 90 provides control of the ragweed at the optimal rate. Herbicide Basta 150 SL, RK is more effective to apply twice.

Published: May 2020

Goal. most of the herbologists rarely classify their weeds. Some types of weeds are sometimes given only epithets. But it is necessary to divide the weeds into larger groups, and the most important thing is to determine them by their quantitative indicators and not the qualitative epithets.
Methods. Field, analytical.
Results. For 45 years the experience of crops inspection was mainly carried out in the Kharkiv region. In these years of herbological monitoring perfect methods were carried out. Previously the following prevalence groups were established: very wide, wide, moderate, small, and very small. Later another “moderately broad” group was added. In the conditions of North-Eastern Ukraine the main survey of the arable land, which lasted for several decades, has established 270 species. The weeds grouped the floral list into six parts. The analyses of the group respectively: very wide, wide, moderately wide, moderately small and very small found that the number of species was 1.9, 1.9, 4.4, 6.7, 17.3 and 67.8 percent. With the expansion of the weed list, in the group of very small weeds the percentage of species grew. In recent years some adventitious weeds have appeared. These are: four types of Abutilon theophrast Ved., Hibiscus trionum L., Diqitaria ischaemum (Schreb.) Muehl) and Phytolacca americana (L.).
Conclusions. On which territory it is necessary to determine the types of weeds and their criterion of prevalence and dominance. In the list weeds it is necessary to distinguish six groups: very wide, wide, moderately wide, moderate, small, very small. A significant part of the weeds on the list are included in the of the very small ones. In North-Eastern Ukraine, where there are 270 species observed, 67.8% of weeds belong to the last group.

Writing is not always easy to do. The students face some difficulties in mastering writing skill because they need particular practice to develop their writing skill. The teacher should know the students’ abilities and difficulties toward this skill and one of many ways teacher can do is by analyzing students’ compositions. In this research, they are generic structures and language features of analytical exposition texts. They may make students find some difficulties in analytical exposition texts.
This study is descriptive qualitative study and this research is aiming to describe the students’ competence in writing expository text. The researcher is the first instrument and the second instrument for this study is the students’ compositions of analytical exposition texts. To analyze the data, there will be three steps; classification, analysis, and representing to determine whether the students write analytical exposition text with proper generic structures and language features or not.
After being analysis, the researcher found that the students could write analytical exposition texts with a good generic structures and language features. However, there are some students who do not compose them properly. For generic structures, some students often do not write review of arguments in thesis and reiteration. And for language features, some of the students often do not apply the diction well. The students are proficient enough in organizing analytical exposition text in term of generic structures and language features.
From the analysis, the abilities and difficulties of the students can be identified by the teacher. The teacher should give clear explanation and understanding in teaching analytical exposition text. The teacher had to explain about how to make analytical exposition text deeply in order that the students could comprehend the text well. In addition, the English teacher could give comments to the students’ composition for the better next writing assignments, because they will know about the mistakes that they still made.

Published: May 2020

ABSTRACT
The current study aims to explore the students’ preferences on face to face corrective feedback vs online corrective feedback in ESP class. It is an attempt to investigate if they prefer to be corrected directly face to face by teachers or they like to be provided online corrective feedback by the teachers. To do so, a questionnaire was distributed to a group of students who are taking English for Specific Purposes and also focus group discussion was used in order to find out their beliefs toward their corrective feedback preferences. Totally, 50 students who were taking ESP courses at State Polytechnic of Subang participated in this study. The results from the questionnaire analysis revealed that the students preferred their teachers to use face to face corrective feedback, with an overall mean (x̄ = 3,95) in learning effectiveness, (x̄ = 4,12) in learning accuracies, and (x̄ = 4,02) in learning experiences. The focus group discussion revealed the students’ beliefs in their corrective feedback preferences, they believed that the teachers should be able to guide their learning, use communicative ways, and encourage them by using their learning preferences. The study suggested that taking these preferences into consideration could help students to increase their confidence in learning English.

Secara geografis, Desa Tomberabu 1 berjarak kurang lebih 15 km dari Kota Ende dengan ketinggian wilayah rata-rata 780 meter dari permukaan laut dan keadaan topografi terdiri dari bukit dengan kemiringan berkisar 30° - 60°. Mayoritas masyarakat Desa Tomberabu 1 berprofesi sebagai petani dan bermukim di sepanjang lereng yang juga merupakan lahan perkebunanan dan ladang penduduk. Sehngga perlu dipertimbangkan keamanannya dari bahaya longsor, mengingat daerah ini merupakan wilayah dengan intensitas curah hujan cukup tinggi.Analisis ini dilakukan untuk memperoleh deskripsi sampel tanah dan data berupa angka yang akan digunakan untuk mencari nilai faktor keamanan lereng dengan kemiringan mendekati 90o setinggi 10 m. Nilai yang diperoleh adalah SF = 1,003 < 1,2 , nilai ini menyatakan bahwa lereng tersebut dalam kondisi tidak aman. Sehingga perlu dilakukan penanggulangan kelongsoran antara lain dengan mengubah tinggi lereng dengan membuat teras pada ketiggian 5 m, dan diperoleh angka keamanannya SF = 1,318. Walaupun demikian masih perlu juga untuk melakukan perencanaan saluran yang baik serta pembuatan dinding penahan yang sesuai dengan kondisi tanahnya
