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, ...

Compatibility of Soil-Dwelling Predators and Microbial Agents and their Efficacy in Controlling Soil-Dwelling Stages of Western Flower Thrips Frankliniella Occidentalis
Western flower thrips (WFT) generally pupate in the soil. This laboratory study was designed to examine the compatibility of soil-dwelling predators with microbial biocontrol agents and assess their combined efficacy against pupating WFT, with a view to their integrated use. The following commercially available biocontrol agents were evaluated: a rove beetle, Dalotia coriaria (Kraatz); predatory ...

Playing hide and seek below the soil
Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

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 ...

Coir - The Ideal Growing Medium for Strawberries
In June 2015, newspapers around Britain were buzzing about an offer from Marks and Spencer which sought to revolutionize gardening and retail shopping. For the first time in history, UK shoppers were given the opportunity to pick their strawberries from the store itself. These strawberries, which are grown in baskets and under LED lights, added a new dimension to the definition of fresh. ...

Effects of bisphenol a on key enzymes in cellular respiration of soybean seedling roots
Environmental endocrine disrupter–bisphenol A (BPA) is ubiquitous in the environment, with potential toxic effects on plants. Previous studies found a significant effect of BPA on levels of mineral nutrients in plant roots, but the underlying mechanism remains unknown. To determine how BPA influences root mineral nutrients, the effects of BPA (1.5, 3.0, 6.0, 12.0, 24.0, 48.0 and 96.0 mg L−1) ...

Toxicity in relation to mode of action for the nematode Caenorhabditis elegans: Acute‐to‐chronic ratios and quantitative structure‐activity relationships
Acute‐to‐chronic ratios (ACRs) and quantitative structure‐activity relationships (QSARs) generate continuous interest in particular in chemical risk assessment. Previous studies focusing on the relationship between the size or variation of ACRs to substance classes and QSAR‐models were often based on data for standard test organisms, such as daphnids and fish. For the present study, we ...

Agriculture Plant Nursery - Case Study
Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness and microbiological contaminants. The plants were slow growing. Solution Genesis Water Technologies ...

A New Generation of GMOs
Is synthetic biology on its way to our farms, markets and tables? Thousands of researchers will descend on Boston this fall for an event billed as the world’s largest gathering of synthetic biologists. The field is evolving so rapidly that even scientists working in it don’t agree on a definition, but at its core synthetic biology involves bringing engineering principles to ...

Effects of herbicide‐treated host plants on the development of Mamestra brassicae L. caterpillars
Herbicides are widely used pesticides that affect plants by changing their chemistry. In doing so, herbicides might also influence the quality of plants as food for herbivores. To study the effects of herbicides on host plant quality, we treated 3 plant species (Plantago lanceolata L., P. major L., and Ranunculus acris L.) with sublethal rates of either a sulfonylurea (Atlantis WG, Bayer ...

Nano silicon dioxide mitigates the adverse effects of salt stress on Cucurbita pepo L
Nanotechnology, an emerging science, has advanced research in almost all fields of technology. The aim of the present study was to evaluate the role of nano silicon dioxide (nSiO) in plant resistance to salt stress through improving the antioxidant system of squash (Cucurbita pepo L. cv. White Bush Marrow). We found that seeds treated with NaCl showed reduced germination percentage, vigor ...

Chicago Council lists three-decade changes in greenhouse gases and average temperature
In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a cooling or warming period. It is ...

AgroMET Pest forecasts come to Connecticut - Case Study
It hurts when codling moths riddle your apples, powdery mildew blasts your grapes, or anthracnose takes over your turf. But it's really nettlesome when growers or groundskeepers mere miles away get off without a snag. Blame it on the weather: on a multitude of variables that we barely notice. Sophisticated weather stations can pick up on those variables and even predict when and where pests will ...
