Potatoes are a universal crop, also called "second bread", because the level of consumption of this vegetable in the country is very high. It is, at the same time, a foodstuff, raw material for the processing industry, high quality livestock feed and a source of cash for farms and households. In terms of consumption and geographical spread, potatoes occupy one of the leading positions in the structure of food production in Ukraine. In the Vinnytsia region, the area of potatoes occupies 115-118 thousand hectares and the average yield is 120-130 cts / ha, which is several times less potential of this crop. One of the reasons for the low yield of potatoes is the harmfulness of pests and diseases. The most common diseases of potatoes include blight, which is steadily developing and is able to reduce the yield of tubers, their quality. In Ukraine, crop losses from it account for 16-22%, and in the years of epiphytoties can reach 50%. The evaluation of plant diseases is one of the most important and often the most challenging tasks in the epidemiology of plant diseases. Damage to plants by phytophages and pathogens can very quickly result in complete loss of the crop if there is insufficient crop protection. This article confirms the feasibility and effectiveness of the application of modern-day protector tubers and the use of new generation growth promoters and fungicides during the cultivation of tubers. This article confirms the feasibility and effectiveness of the application of modern-day protector tubers and the use of new generation growth promoters and fungicides during the cultivation of tubers. To obtain a crop of potato varieties Povin 285,7 c/ha, which is 58,2 c/ha more than the control, it is necessary to carry out the cultivation of tubers before disembarking the detergent Emesto quantum 273,5 FS, TN, in the rate of 1.2 l of the preparation per ton of planting material, and a growth promoter of Rostock (3 l/t), as well as spraying during the vegetation of plants with fungicides Antracol 70 WP, RF (1,0 kg/ha), Nativo 75 WG, VG (0,3 kg/ha) , Infinito 687.5 SC, COP (1.0 l/ha) and Rostock Bohr and Rostock Iron (1.5 l/ha).

Diagnostic Capabilities

Venezuela is currently experiencing the most severe humanitarian crisis in the Americas of this century. Little food is being produced locally, despite the population's right to food. Plant disease outbreaks are causing substantial declines in major staple food and cash crops, and this impacts on rural livelihoods, and poses a significant and growing threat to the already complex food insecurity crisis in the country. Nonetheless, phytosanitary services and hence the control of plant pests and diseases have been substantially weakened over the recent years as a consequence of the collapse of the economy and the substantial deterioration of government services. Therefore, most of the pathogens associated with symptoms-causing diseases remain unidentified or uncharacterized, and no surveillance or crop protection strategies have been implemented. In this review, we address the country's issues and challenges in diagnosing, monitoring and managing plant diseases to restore national food security.

Abstract Background The development of ecofriendly tools against plant diseases is an important issue in crop protection. Screening and selection process of bacterial strains antagonists of 2 pathogenic bacterial species that limit very important crops, Erwinia amylovora, the causal agent of the fire blight disease, and Pectobacterium carotovorum, the causal agent of bacterial potato soft rot, were reported. Bacterial colonies were isolated from different ecological niches, where both pathogens were found: rhizosphere of potato tubers and fruits and leaves of pear trees from the northwest region of Algeria. Direct and indirect confrontation tests against strains of E. amylovora and P. carotovorum were performed. Results Results showed a significant antagonistic activity against both phytopathogenic species, using direct confrontation method and supernatants of cultures (p<0.005). In vitro assays showed growth inhibitions of both phytopathogenic species. Furthermore, results revealed that the strains of S. plymuthica had a better inhibitory effect than the strains of P. fluorescens against both pathogens. In vivo results on immature pear fruits showed a significant decrease in the progression of the fire blight symptoms, with a variation in the infection index from one antagonistic strain to another between 31.3 and 50%, and slice of potato showed total inhibition of the pathogen (P. carotovorum) by the antagonistic strains of Serratia plymuthica (p<0.005). Conclusion This study highlighted that the effective bacteria did not show any infection signs towards plant tissue, and considered as a potential strategy to limit the fire blight and soft rot diseases.

A study was conducted to determine the efficacy of three most commonly used growth promoters from different pharmaceutical companies on growth performance of hybrid walking catfish (Clarias batrachus × Clarias gariepinus). The experiment was done in the wet laboratory of the Department of Aquaculture, BAU, Mymensingh, with a total of 10 aquaria and 160 fish having mean initial weight of 6.3 ± 0.48 g. The three growth promoters, “Charger gel” from Fishtech (BD) Ltd., “Growth gel” from Advance Agrotech (BD) Ltd. and “Hepaprotect-aqua” from Renata Animal health Ltd., were used in separate nine (9) aquaria at recommended, lower dose and higher dose respectively. One aquarium was used as control (diet without any growth promoter). The fish were fed with paragon nursery floating feed at 20% of body weight in each aquarium for 28 days. Doses of Charger gel were given as 80, 60 and 100 mg/20 g feed/day, that of Growth gel, 0.14, 0.12 and 0.16 ml/20 g feed/day and of Hepaprotect-aqua, 30, 15 and 50 mg/20 g feed/day. Re-circulatory system was used throughout the experimental period. By applying recommended, lower and higher dose of “Charger gel”, mean final weights were found as 23.0, 21.9 and 35.9 g; average daily weight gain as 0.60, 0.56 and 1.06 g and specific growth rate (SGR) as 2.01, 1.93 and 2.70% respectively. For “Growth gel”, mean final weights were found as 22.8, 17.3 and 31.1 g; average daily weight gain as 0.59, 0.39 and 0.88 g and SGR as 1.99, 1.57 and 2.48 % respectively. For “Hepaprotect-aqua”, mean final weights were found as 24.2, 17.5 and 28.2 g; average daily weight gain as 0.64, 0.40 and 0.78 g and SGR as 2.09, 1.58 and 2.32% respectively. In all the cases survival rates were 100%. All the three growth promoters showed better results at their higher doses in comparison to their results in lower and recommended doses. However, in average Charger gel showed the best result than the other two growth promoters. This information on the efficacy study of growth promoters needs to be disseminated to the farmers for improved fish production.Asian J. Med. Biol. Res. March 2017, 3(1): 103-108

All farmers and growers have at some time faced the decision of whether to control a pest in their crop. In order to make the correct decision the farmer needs access to, and an understanding of, sufficient information relevant to such pest problems. Decision support systems are able to help farmers make these difficult decisions by providing information in an easily understandable and quickly accessed form. The increasing use of computers by farmers for record-keeping and business management is putting the hardware necessary for the implementation of these systems onto more and more farms. The scarcity of expert advice, increasingly complex decisions and reduced economic margins all increase the importance of making the right pest management decision at the right time. It is against this background that decision support systems have an important role to play in the fight against losses caused by pests and diseases.

Animal Consumption

Brewing industry generates a main residue, brewers’ spent grain (BSG), which has good properties both for use in animal consumption and for thermal use, but contains a very high content of moisture (20–25% dry matter content), so that its elimination or treatment should be immediate, since it can cause degeneration problems of the product. Currently, brewers often supply this material at low cost for use as livestock feed. This solution is not efficiently carried out without reporting too much benefit to the brewers more than to eliminate waste from their facilities. However, BSG is a raw material of interest for application in different areas due to its low price, availability throughout the year and a valuable chemical composition, so it seems necessary to look for an alternative use to give value to these characteristics. In this paper a drying study is carried out in order to establish the foundations for its energy use by thermal of BSG. BSG has been used from a craft brewery located at Badajoz, Spain. Drying analysis was carried out for various temperatures and inlet air flow by means a convective dryer. The properties studied show that BSG can be used for thermal utilization in large installations, being necessary heat drying processes as a pretreatment in order to obtain a biofuel with acceptable efficiency.

The goal of enteral nutritional support for infants born preterm or small for gestational age (SGA) is to achieve normal growth and development. Yet, this is difficult to achieve because of intestinal immaturity. Our objective was to determine if birth weight, protein intake, and the growth promoters leucine (10 g/L) or calcium-ß-hydroxy-ß-methylbutryate (HMB; 1.1 g/L) would affect trajectories of intestinal growth and functions and weights of other organs. Preterm pigs were delivered at gestational day 105 (91% of term) and fed for 6 or 7 days isocaloric formulas that differed in protein content (50 g or 100 g protein/L), with and without the growth promoters leucine or HMB. For comparative purposes organ weights were measured within 12 h after delivery for six term pigs of low and six of average birth weights. The responses of intestinal growth and total intestinal brush border membrane carbohydrases to protein level and supplemental leucine were of greater magnitude for preterm pigs of lower birth weight. Forskolin stimulated chloride secretion in the proximal small intestine was lower for pigs fed the low protein milk replacers. Capacities of the entire small intestine to transport glucose (mmol/kg-day) were not responsive to protein level, leucine, or HMB, and did not differ between small and large pigs. Relative organ weights of the small and average weight term pigs were similar, but some differed from those of the preterm pigs suggesting preterm birth and the standards of care used for this study altered the trajectories of development for the intestine and other organs. Although leucine is an effective generalized growth promoter that enhances gut development of small preterm pigs, it does not mitigate compromised neurodevelopment. Our findings using preterm pigs as a relevant preclinical model indicate nutrition support strategies can influence development of some gastrointestinal tract characteristics and the growth of other organs.

The genus Viburnum encompasses a group of about 150 species of evergreen, semi-evergreen or deciduous trees and large shrubs. Viburnums are native to temperate, subtropical and tropical areas of southeastern Asia, eastern North America, Central America, the Caribbean and parts of South America. Native and nonnative Viburnum species have become prominent landscape plants in the southeastern United States due to their beauty, utility, relative ease of maintenance and broad adaptability to the region's climate and soils. Efficient management of viburnum pests to maintain healthy viburnum plants in nurseries and landscape settings is crucial for sustaining the economic competitiveness and profitability of green industry professionals competing in the horticulture marketplace. Diversity of species within the genus, however, is vast, and can contribute to many host-pest complexes that differ among growing environments and cause severe economic or aesthetic losses. Additionally, some abiotic disorders may mimic biotic damage or may render viburnum more susceptible to pests and diseases. This review focuses on viburnum culture in production and landscape settings with an emphasis on major insect and mite pests, plant diseases and abiotic disorders affecting management of Viburnum species in nursery and landscape settings.

A field experiment involving the cultivation of common valerian was conducted on loess soil in Abramów (Lublin region) in the period 2007-2009. Qualitative parameters of herbal raw material obtained from this plant as well as in-crop weed infestation were evaluated depending on the protection method and forecrop. Hand-weeded plots, in which a hand hoe was used, were the control. In the other treatments, weeds were controlled using various herbicides and a mechanical implement (brush weeder). Potato and winter wheat + field pea cover crop were the forecrops for common valerian crops. A hypothesis was made that the use of a brush weeder and herbicides not registered for application in valerian crops would have a positive effect on this plant's productivity and weed infestation in its crops. It was also assumed that the introduction of a cover crop would allow the elimination of differences in the forecrop value of the crop stands in question. The best quantitative and qualitative parameters of common valerian raw material as well as the largest reduction of incrop weed infestation were recorded after the application of the herbicides which were not type approved. The use of the brush weeder in the interrows also had a beneficial effect on productivity of the plant in question, but secondary weed infestation at the end of the growing season of common valerian turned out to be its disadvantage. Traditional crop protection methods used in common valerian crops were less effective in weed infestation reduction and they resulted in lower plant productivity and raw material quality. Potato proved to be a better forecrop for common valerian than winter wheat + field pea; however, this positive effect was not confirmed statistically. The following annual weeds: <i>Chenopodium album</i>, <i>Galinsoga parviflora</i>, <i>Stellaria media</i>, were predominant in the common valerian crop. Traditional weed control methods resulted in the dominance of some dicotyledonous weeds, such as <i>Viola arvensis</i>, <i>Galium aparine</i>, <i>Capsella bursa-pastoris</i>.

Late blight caused by Phytophthora infestans is an important disease on potato.  Several potato hybrids have been generated by crossing local varieties (Atlantic and Granola) with Katahdin SP951 which contains late blight resistance gene RB.  Prior to release, these hybrids need to be evaluated for their environ-mental effects on non-target organisms and natural pests and diseases. The objectives of the study were to investigate the effect of LBR potato hybrids on beneficial soil microbes, pests and diseases. The trial was conducted in the confined field trial (CFT) in Lembang, West Java. The parental non-transgenic (NT) clones (Granola, Atlantic and Katahdin) and LBR hybrids (four clones of Atlantic x Katahdin SP951 hybrids; 10 clones of Granola x Katahdin SP951) were planted at a plant spacing of 30 cm x 70 cm. Fungicide applications were used as treat-ments (no spray, five and twenty times sprays). The experi-ment was arranged in a randomized completely block design with three replications. The parameters determined were popula-tions of N2 fixing and P solubilizing bacteria, soil C/N ratio as well as natural pests and diseases. The results showed that the transgenic LBR potato hybrids did not have negative effect on N fixing bacteria. The bacterial populations were around 1010-11 cells g-1 soil before planting, 1012 cells at 1.5 months after planting (MAP) and 108 cells after harvest. For P- solubilizing bacteria, their populations were 1010 cells before planting, 1012 cells at 1.5 MAP and 1011 cells g-1  soil after harvest. The soil C/N ratio of the transgenic plot was not statistically different compared to non-transgenic plot, i.e. 12-15 before planting, 10-11 at 1.5 MAP, and 10 after harvest in non-spray plot. Pests and diseases such as Alternaria solani, Liriomyza, potato tubber moth, aphid and mites on the transgenic and non-transgenic plots were statistically not different. The resistance score for A. solani was 7.2 (parental tansgenic) and 7.6 (parental non-transgenic); for Liriomyza it was 2.07 (parental transgenic) and 2.32 insect per plant (parental non-transgenic), the PTM was 0.63 (parental transgenic) and 0.73 insect per plant (parental non-transgenic), aphid and mites were 0.75 (parental transgenic) and 1.68 insects per plant (parental non-transgenic). The study indicated that LBR potato hybrids did not have any negative impacts on non-target organisms.

The purposes of community service entitled "Kaliandra Planting as Energy Wood and Forage Livestock Feed on Agroforestry Crops Gerbosari Village Community Samigaluh Kulon Progo" are 1). To provide additional knowledge of Kaliandra (Calliandracallothyrsus) utilisation other than HMT that is as a raw material of energy source and 2). To practice the technique of Kaliandra planting on agroforestry system in Gerbosari Village. The way cattle developed in Dusun Keceme is "cut and carry system" or grazing system. Grazing systems make farmers provide land for HMT planting either in the form of grass or tree leaves. Public dissemination and discussion with the community resulted in an agreement that the program is not only Kaliandra planting, but the utilisation of Kaliandra as an energy wood and wood pellet introduction is needed by Keceme Hamlet community. Methods of implementation of community service are through 4 stages in one unity of scheme. The methods are 1) program dissemination, 2) counselling, 3) practice of using a wood pellet stove and 4) planting. The community service program can provide an initial understanding of the community of Keceme Hamlet about the benefits of Kaliandra as an alternative to renewable energy that is in the form of wood pellets. The technique of agroforestry cultivation of Kaliandra has long been practised by the people of Keceme Hamlet that is on the edge of the terrace of the land.
