Evaluate the effectiveness of various soybean protection schemes using preventive measures for seedlings and control measures during the growing season. \u0000Methods. Field, phytopathological, herbological, mathematical and statistical. According to the first protection scheme, the seeds were treated comprehensively with Maxim XL 035 FS (fludioxonil, 25 g/l + metalaxyl-M, 10 g/l) fungicide, 0.5 l/t, Taboo s.c. (imidacloprid, 500 g/l) insecticide, 0.5 l/t and Biomag-Soya (Bradirhizobium japonicum) biological product, village, 2.5 l/t. Harnes c.e. (acetochlor, 900 g/l), herbicide was applied during sowing with a consumption rate of 2.0 l/ha. According to the second scheme during the growing season herbicides Bazagran, l.c. (bentazone, 480 g/l) with a rate of 2.5 l/ha and Panther, c.e., 1.0 l/ha (quizalofop-P-tefuril, 40 g/l) in the phase of 3—4 true leaves in culture. Against diseases in the budding phase — the beginning of flowering and at the beginning of bean formation was sprayed with fungicide systemic contact action Amistar Extra 280 SC (cyproconazole, 200 g/l + azoxystrobin, 80 g/l), 0.75 l/ha. The quantitative and species composition of weeds in the experimental plots, the infestation of phytopathogens of soybean plants, the effectiveness of drugs in various protection schemes, crop yield were determined. \u0000Results. Both protection schemes effectively controlled weed infestation and disease. The first protection scheme proved to be more effective against dicotyledonous weeds: the effectiveness 60 days after herbicide application was 95.4% versus 82% according to the second scheme. Cereal weeds were more effectively controlled during the growing season. Protection of soybeans against Alternaria was almost equally effective in both schemes. Soybean downy mildew more effectively limited fungicidal treatments during the growing season. Under both protection schemes, soybeans yielded significantly higher yields than controls. However, yields, number of beans per plant and weight of 1000 grains were higher in the first scheme compared to the second protection scheme. \u0000Conclusions. Both protection schemes provided high weed and disease control rates during the soybean growing season. Differences in the control of different biological groups of weeds and different types of diseases are obviously related to the peculiarities of the use and toxic effects of the drugs used. However, the application of a system of preventive protection measures can reduce the pesticide load on the agrocenosis and limit the negative impact of pesticides on soybean plants during the growing season.","PeriodicalId":238317,"journal":{"name":"Karantin i zahist roslin","volume":"595 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116175858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine the colonization of pear plantations by mites in horticultural farms of Ukraine, route surveys were carried out in the industrial pear plantations of Yablunivska variety. The planting scheme was 0.8 × 3.5 m. The planting year was 2014. The crown shape was thinned (improved) and story. The rootstock was a quince tree A. Stages of plant development at the time of treatment were «bursting buds (green cone)» (BBCH 10), «white buds» (BBCH 55), «end of flowering» (BBCH 69) and «fruit development» BBCH 75). The technical effectiveness of pesticides at different application rates was determined. The accounts were performed according to generally accepted methods in horticulture, plant protection and entomology. \u0000Results. Female pear leaf blister mite overwinter under the upper scales of the buds. In spring, at an average daily temperature above 10°C, they begin to feed with the juice of young leaves, covering them with galls, and lay eggs («bud bursting (green cone)» — «white bud») stages. The development of the first generation ends at the end of «flowering». Females of the second generation appear in late June, the third generation — in the first half of July. After rebirth, they leave galls and populate the buds for wintering (mid-late June to late Julyearly August). During the growing season the phytophagan develops in three generations. The use of Danadim stable, KE, Fufanon 570, KE, Sivanto Prime 200 SL, PK, Oberon Rapid 240 SC and Aktofit, KE provided a reduction in the number of this species by 75.3—93.9%, allowed to increase the effectiveness of basic biometric and biochemical indices of plantations, to obtain high-quality products with a yield of 1.1—1.5 times higher comparing with the control. \u0000Conclusions. During the growing season, the pear gall mite develops in three generations. Taking into account the peculiarities of the biology of pears and mites in the spring, the peculiarities of the mechanism of action of drugs against this species and other phytophages (leafeating, stem, sucking, including against the brown-marble bug) are most advisable to apply: in the phase of «bud break (green cone)» — Danadim stable, EC (2.0 l/ ha); in the «white bud» phase — Fufanon 570, EC (2.0 l/ha); after the «end of flowering» — Danadim stable, EC (2.0 l/ha).

Differences in Septoria leaf spot resistance in sunflower breeding lines on a stationary infectious background were found. Among the lines, the most affected by Septoria leaf spot was the line ZL58A and had from 88.8% to 97.9% of plants with symptoms of the disease. ZL70A and ZL78A lines were significantly less affected by desease than the previous line. Healthy plants for two years of research in these samples were from 73.3% to 87.5%. The HAR7 line was close to the previous two lines, the number of diseased plants varied in different years from 16.7% to 40%, and without lesions from 60% to 83.3%. This line had some differences in the intensity of the disease during the two experimental years. As a result of the study, it was found that the hybrid ZL58A × HAR7 was most affected by Septoria leaf spot. The number of affected plants in both years of research ranged from 80.8% to 90.3%. This sample was susceptible to the disease, as well as the maternal line ZL58A. Hybrids of the first generation of the combinations ZL70A × HAR7 and ZL78A × HAR7 were the least affected.

Observations of the phytosanitary condition of plane trees were carried out by the method of route surveys in botanical gardens, parks, garden squares and street plantations in Kyiv (2019—2021). During the growing season, the lower side of the leaves and branches up to 1.5—2.0 m from the soil surface were inspected. Photographic equipment with the function of zooming in on the object (at least 10× «zooms») and subsequent computer processing was used to examine the leaves damaged by bedbugs on the treetops above. \u0000Results. Data on the degree of sycamore lace bug damage of plants in different localities of growth of plane trees in the megalopolis and the resistance of phytophagous to the extreme influence of abiotic environmental factors in this geographical area. Mass reproduction of bugs and significant damage to the leaves of plane trees we noted on the old plane trees on Holosiivskyi Avenue and Holosiivskyi Park named after M. Rylsky. Young plantations of plane trees (near the metro station «Exhibition Center», near the park named after M. Zankovetskoi and Velyka Vasylkivska Street) are damaged by lace bugs to a much lesser extent than the above-mentioned old ones. Survey of the collection of plane trees (Platanus occidentalis L., P. orientalis L., P. × acerifolia Ait., Willd.) in the Botanical Garden named after Acad. O.V. Fomina showed that no bug C.ciliata was found during all these years.

According to our results, extracts of sage (Salvia officinalis L.), annual wormwood (Artemisia annua L.) and plume poppy (Macleaya cordata L.) showed a pronounced fungistatic effect against Alternaria tenuissima. These data suggest that extracts of these plants can be used in the future to develop plant protection products.","PeriodicalId":238317,"journal":{"name":"Karantin i zahist roslin","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126586794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Substantiate the use of environmentally friendly means of protecting peas with modern technologies of crop cultivation. \u0000Methods. Field, laboratory, mathematical-statistical, calculation. \u0000Results. The relationship between the spread of diseases and the main environmental factors (temperature and humidity, atmospheric precipitation) during the growing season of plants has been investigated. The terms and norms of processing with biological products and their effectiveness have been established. Methodological recommendations have been developed for the use of environmentally friendly means of protection, which are based on the use of biological preparations in pea agrocenoses and in the production of organic products. \u0000Conclusions. In agrocenoses of peas, the use of biological plant protection products for the production of organic products is recommended.","PeriodicalId":238317,"journal":{"name":"Karantin i zahist roslin","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116427744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
