Fruit And Vegetable Juice
APPLE JUICE Apple juice in the press process will bring a lot of impurities in pulp, pectin, starch, plant fiber, microorganisms, bacteria, and other impurities. Thus, it's not easy to produce apple juice concentrate through traditional methods. Due to high sugar content in apple juice, microorganisms and bacteria are easy to breed which makes apple juice fermentation ferment and deteriorate. ...

USDA Comment Request: Draft Documents Related to GE Soybean Deregulation
On, March 12, 2019, USDA’s Animal and Plant Health Inspection Service (APHIS) announced the publication of two draft documents related to the potential deregulation of a soybean variety GE for increased yield and resistance to the herbicide glufosinate. The draft documents are Draft Plant Pest Risk Assessment (PPRA) and Draft Environmental Assessment (dEA) for Petition to Deregulate GE ...

Nitrogen Fixers
Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...

Increasing Lettuce Coloration with LEDs
Using LED grow lights in plant production is a relatively new branch of science. In vertical farming where artificial light sources are used in closed environment it is important to collect data about the individual plant species to be able to produce the right spectrum and light intensity for vegetative and generative growth. Light spectrums can also be used to manipulate the plants growth cycle ...

Why are we monitoring nutrients at different depths?
Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

Fungal diseases are on the rise. Is environmental change to blame?
Scientists and physicians are looking for clues to a worrying increase in fungal infections and exploring ways to reduce the threat. Fungi are everywhere — from the mushrooms that decompose fallen logs in the forest, to the mold that grows in your bathtub, to the microscopic fungal cells that reside naturally on your skin. Scientists estimate there are 1.5 million species of fungi on the ...

The efficacy of disinfectants against plant pathogens
In late 2015, a journal article from the European Journal of Plant Pathology was published on research regarding the efficacy of different disinfectants against plant pathogens in irrigation water. All testing as done by the Department of Primary Industries here in Australia for the horticulture and agriculture industries. The disinfectants tested included chlorine, chlorine dioxide (using our ...

Study: Biological treatments in early production of tomatoes
At Vineland Research and Innovation Centre in Ontario, Plant Pathology Research Technician Travis Cranmer is working to analyze the efficacy of biopesticides against root diseases in hydroponic tomato production. The study’s findings were released at the Canadian Greenhouse Conference in Niagara Falls in October 2016. Cranmer shares some of his ...

Ontario Horticulture Research Priority Report 2016
Sector Consultation The Ontario Fruit and Vegetable Growers Association partnered with Vineland to host a research strategy workshop in November 2014 with the goal of defining the top five research priorities for each crop group. Grower organizations were invited to nominate two representatives to participate on their behalf and a number of researchers from relevant fields were invited to ...

The Latest in Whitefly Control
Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

Biopesticides Examined for Role in Field Production
Biopesticides deserve respect. Once derided as snake oil, today’s products have proven benefits in suppressing pest organisms. Whether they activate plant defenses, parasitize or inhibit pathogen growth or make the environment less favourable to disease, they can play an integral role in crop protection. While the greenhouse sector first excelled at incorporating biopesticides in ...

Biotechnology: APHIS Seeks Comment on Potentially Significant Changes to Regulations Regarding GE Organisms
According to a Federal Register notice published on February 5, 2016, 81 Fed. Reg. 6225, the U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) announced its intent to "prepare a programmatic environmental impact statement (EIS) in connection with potential changes to the regulations regarding the importation, interstate movement, and environmental release ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

Environmental Groups File Opening Briefs Challenging EPA’s Decision to Register Enlist Duo
On October 23, 2015, in the U.S. Court of Appeals for the Ninth Circuit, the Natural Resources Defense Council (NRDC) and other environmental groups including the Center for Food Safety (CFS, et al.) (together, Petitioners) filed separate opening briefs in Case Nos. 14-73353 and 14-73359 (consolidated) arguing that the U.S. Environmental Protection Agency’s (EPA) decision to register Dow ...

The DNA of the U.S. Regulatory System: Are We Getting It Right For Synthetic Biology?
U.S. regulatory oversight of synthetic biology across the board needs to be modernized to reflect and address the promising technologies routinely entering the market. From a statutory perspective, the pertinent laws appear sufficiently broad to empower federal agencies to address potential risks and promote the potential benefits of synthetic biology. The regulatory infrastructure, however, is ...

Effect of nano-silver particles on postharvest life of Lilium orientalis cv. ‘Shocking’
Prolongation of vase life of cut lilies ( Lilium orientalis cv. ‘Shocking’) was studied in vase containing 5, 15, 25, 35 ppm of nano-silver solutions and deionised water as control under controlled conditions. All nano-silver treatments extended the longevity of cut flowers in comparison to control but the concentration of 35 ppm showed the highest vase solution uptake, initial fresh weight ...

Cassava: a promising food security crop in Mutomo, a semi-arid food deficit district in Kitui County of Kenya
Cassava is ideal for production and provision of carbohydrates in the marginal and drought-prone areas, which comprise about 80% of Kenya. However, its potential utilisation as a food security crop remains low in these areas. A major constraint to cassava production is lack of adequate disease and pest-free planting materials greatly exacerbated by its low multiplication rate. The Kenya ...
