Pesticide Residues in Fruits and Vegetables from Farmers’ Markets

Authored by Beatrice N Dingha

Abstract
Pesticides are important in crop production worldwide. Many commonly grown fruits and vegetables require pesticide protection. The consequences of using pesticides for food production can be far-reaching, and farm produce may contain pesticide residues that pose serious health and environmental risks. In this paper, we review the Electrical Penetration Graph (EPG) and explore the potential for its use in food safety. Several pesticide residues were found on produce obtained from farmers’ markets. The results indicate that the EPG could be a useful tool for detecting pesticide residues. In conclusion, we emphasize the need for case-driven Integrated Pest Management (IPM) approaches that produce safe food and high yield.

Introduction
Food safety concerns continue to be important to agriculture in many parts of the world. Many farmers use chemical pesticides to control insect pests, weeds and diseases to obtain high yields, quality and blemish free appearance to meet standards imposed by consumers. Residues from pesticides may still be present on produce and may have long-term adverse effects on human health [1]. It is therefore not surprising that over 90 percent of consumers are concerned about pesticide and fertilizer residues in food and food products [2,3]. In the USA, farmers’ markets represent an attractive outlet where consumers purchase fresh produce directly from the producer. The number of farmers’ market has grown significantly, with a 79% increase from 1994 to 2002 [4].

Juniper Publishers- Open Access Journal of Environmental Sciences & Natural Resources Impact of Various Levels of Phosphorus on Wheat (CV.PIRSABAK-2013) Authored by Sajid Islam Abstract An experiment was conducted at Cereals Crops Research Institute Pirsabak Nowhere on 'Impact of various levels of phosphorus on Wheat (cv. PIRSABAK-2103) during winter 2014-15. The experiment consisted of single factor i.e. phosphorus levels 0, 45, 60, 75 and 90 kg ha -1 . The experiment was carried out in simple randomized complete block (RCB) design, having three replications. Sub plot size was 5m x 1.8m. Row to row distance was kept as 30 cm. Agronomical treatments were kept the same for all the plots. Leaf area tiller -1 , days to heading, days to physiological maturity, plant height, spikes m -2 , spike length, grains spike -1 , thousands grains weight, biological yield and grain yield were significantly (p<0.05) affected by various levels of phosphorus. Maximum weight of thousand grai

  Juniper Publishers-Open Access Journal of Environmental Sciences & Natural Resources The European Social Innovation Competition Lottery Authored by Luigi Antonio Pezone Introduction I participate in the "2018 European Social Innovation Competition" even though this competition is a real lottery, to make known my environmental solutions, which go beyond this competition, because, I believe that the current model of development is unsustainable and cannot be understood by those who do not observe the development from different scientific and practical points of view that can be acquired only after many years of transversal experiences, which modern society does not allow to acquire, as it rewards specialists in individual sectors. Global reasoning is essential to develop sustainable innovative social projects. But it is also difficult that these projects can be understood by the judges of these types of competitions, if they do not know the global design project. Indeed,

Juniper Publishers- Open Access Journal of Environmental Sciences & Natural Resources Plant Microbiomes and Its Beneficial Multifunctional Plant Growth Promoting Attributes Authored by Ajar Nath Yadav Abstract Plant microbiome (Epiphytic, endophytic and rhizospheric) plays important role in plant growth, development, and soil health. Plant and rhizospheric soil are valuable natural resource harbouring hotspots of microbes, and it plays critical roles in the maintenance of global nutrient balance and ecosystem function. The diverse group of microbes is key components of soil-plant systems, where they are engaged in an intense network of interactions in the rhizosphere/phyllospheric/endophytic. The microbes with plant growth promoting (PGP) attributes have emerged as an important and promising tool for sustainable agriculture. PGP microbes promote plant growth and development directly or indirectly, either by releasing plant growth regulators/phytohormones;
