: The increase of crop production along with stricter requirements on food security have augmented the demand of new and eco-friendly bactericides. Most of the bactericides used at the moment consist of persistent organic substances, representing a risk for environmental and human health. For instance, agriculture bactericides used for crop protection includes copper-based, dithiocarbamate and amide bactericides, which are not biodegradable, resulting in the necessity of further research about the production of new active principles that attack microorganisms without producing any harmful effect on human health or environment. The biosurfactant extract evaluated in this work as a bactericide, is obtained from corn steep water, a residual stream of corn wet milling industry, which is fermented spontaneously by probiotic lactic acid bacteria that possess the capacity to produce biosurfactants. In previous works, it has been demonstrated that this biosurfactant extract is able to promote the growth of Lactobacillus casei in drinkable yogurts, though its antimicrobial activity against pathogenic strains has not been evaluated at the moment. The results obtained in this work have proved that this biosurfactant extract is effective as bactericide against Pseudomonas aeruginosa and Escherichia coli, at concentrations of 1 mg/mL, opening the door to its use in agrifood formulations for reducing the use of chemical pesticides and preservatives.

Recent human cohort studies reported positive associations between organic food consumption and a lower incidence of obesity, cancer, and several other diseases. However, there are very few animal and human dietary intervention studies that provide supporting evidence or a mechanistic understanding of these associations. Here we report results from a two-generation, dietary intervention study with male Wistar rats to identify the effects of feeds made from organic and conventional crops on growth, hormonal, and immune system parameters that are known to affect the risk of a number of chronic, non-communicable diseases in animals and humans. A 2 × 2 factorial design was used to separate the effects of contrasting crop protection methods (use or non-use of synthetic chemical pesticides) and fertilizers (mineral nitrogen, phosphorus and potassium (NPK) fertilizers vs. manure use) applied in conventional and organic crop production. Conventional, pesticide-based crop protection resulted in significantly lower fiber, polyphenol, flavonoid, and lutein, but higher lipid, aldicarb, and diquat concentrations in animal feeds. Conventional, mineral NPK-based fertilization resulted in significantly lower polyphenol, but higher cadmium and protein concentrations in feeds. Feed composition differences resulting from the use of pesticides and/or mineral NPK-fertilizer had a significant effect on feed intake, weight gain, plasma hormone, and immunoglobulin concentrations, and lymphocyte proliferation in both generations of rats and in the second generation also on the body weight at weaning. Results suggest that relatively small changes in dietary intakes of (a) protein, lipids, and fiber, (b) toxic and/or endocrine-disrupting pesticides and metals, and (c) polyphenols and other antioxidants (resulting from pesticide and/or mineral NPK-fertilizer use) had complex and often interactive effects on endocrine, immune systems and growth parameters in rats. However, the physiological responses to contrasting feed composition/intake profiles differed substantially between the first and second generations of rats. This may indicate epigenetic programming and/or the generation of “adaptive” phenotypes and should be investigated further.

The demand for organic food is a prerequisite for the formation and development of organic agriculture, and the task of promoting it on domestic and foreign markets is among the priority ones. A serious problem in the sale of this category of goods to the domestic food markets of the country is the distrust of potential consumers. It is possible to solve this problem through certification and the use of a well-known brand. Certification of manufacturers of environmentally friendly products is a rather complicated and expensive procedure, therefore it is not available for most agricultural producers in the Saratov region. However, basing on the fact that today the task of developing the organic agriculture industry is set at the level of the government of the country, it is possible to solve this problem with the support of the state. The article examines the enterprises of the Saratov region of various legal forms, which do not use fertilizers and chemical means of crop protection in the production of crop production. Using the example of agricultural organizations and farms in the region, a mechanism for subsidizing certification of the most promising producers of organic wheat (winter and spring) is proposed, which includes the allocation of targeted subsidies for its implementation. As a criterion for the selection of applicants for this type of state support, as well as the distribution of budgetary resources between them, it is proposed to use the average indicator (potential) of the annual volume of organic production in the work. As a result, direct participants in certification subsidies were selected from the compiled sample of the studied enterprises that do not use chemical plant protection products and mineral fertilizers and the total annual volume of their marketable wheat was determined. The author determined the maximum cost of quality confirmation procedures for one enterprise, taking into account the increasing coefficients per one day of inspection, and also established the largest amount of budgetary resources that may be spent on the implementation of the proposed measure. In order to evaluate the effectiveness of the proposed certification subsidy mechanism, the author developed formulas for determining the selling price of products in the promising organic segment, taking into account its increase by the level of premium premiums.

The Impact

A study was conducted from 2010 to 2012 around the flower growing areas in central Uganda to generate baseline information on the status of pollinators. Primary data were gathered using a questionnaire that aimed at determining farmers and flower farm officials’ perceptions on the impact of activities carried out inside greenhouses on pollinators, human health, and on crop production in the surroundings. Results indicated that the quantity of pesticides and fertilizers applied daily varied among the different flower farms visited. Bee species richness and abundance varied significantly (P<0.01) according to flower farm location, to the landscape vegetation type, and to field types found in the surrounding of flower farms. Bee richness found around flower farms varied in number from 20 to 40 species in total across seasons and years. Bee density increased significantly with the increase in flower density. Small-scale farmers were aware of the value and importance of pollination services in their farming business. There was no clear evidence of a direct effect of agrochemicals application on bee communities living in the surrounding habitats. There is a need for further research to be conducted on human health risks and for toxicological studies on soils, plants, flowers, and bees in the farm landscape.

Though the pesticides have adverse effects but they still are very important in crop protection. Hence, present study on compatibility of fungal bioagent (Trichoderma harzianum) of bacterial leaf blight of rice with chemical pesticides which are commonly used in rice cultivation was carried out with aim to look the possibilities of integrating biological control with chemical control to manage bacterial leaf blight of rice effectively. All the chemical pesticides (fungicides, antibiotic, insecticides and herbicides) exhibited varying adverse effect on mycelial growth of T. harzianum but none of these was antisporulant. Among fungicides and antibiotic, copper oxychloride and streptocycline was compatible with T. harzianum at all concentrations (2000, 1000, 500 and 250 ppm) but mancozeb exhibited compatibility only on lower concentrations (500 and 250 ppm). All insecticides and herbicides were compatible with T. harzianum at all concentrations (2000, 1000, 500 and 250 ppm). Further studies are required in this area of research.
