Three soybean plant introductions possess unique resistance to peanut root-knot nematode
Peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood or Ma] is an increasingly common pest in the southern United States where crops such as peanut (Arachis hypogaea L.) and soybean [Glycine max (L.) Merr.] are grown. Four soybean plant introductions (PIs) are highly resistant to the peanut root-knot nematode. To determine if PI 594403, PI 594427C, and PI 594651B contain useful ...

Effect of fungicide on soybean growth and yield
In response to rising input costs and narrowing profit margins, soybean [Glycine max (L.) Merr.] producers are continually looking for ways to increase soybean yield. One approach being promoted is the use of foliar fungicides, for both foliar pathogen control and nonfungicidal plant physiological effects. The objective of this field experiment was to evaluate a strobilurin and a triazole alone ...

Inheritance and genetic mapping of resistance to Pythium damping-off caused by Pythium Aphanidermatum in ‘Archer’ soybean
Pythium damping-off and root rot of soybean [Glycine max (L.) Merr.] causes poor stands and consequently reduces yields. Resistance to seedling diseases caused by Pythium spp. was reported in the soybean cultivar Archer and was described to be associated with the Rps1k gene for resistance to Phytophthora sojae. To characterize the inheritance of Pythium damping-off resistance in Archer and to ...

Soybean yield and soybean cyst nematode densities related to soil ph, soil carbonate concentrations, and alkalinity stress index
Soybean [Glycine max (L.) Merr.] grown on high pH, calcareous soils often suffer yield loss due to unavailability of Fe. Further yield decline can occur due to infestations by soybean cyst nematodes (Heterodera glycines Ichinohe; SCN) that are often present in greater numbers in high-pH soils. An observational study was conducted from 2001 to 2005 in Iowa to examine the relationships among: pH; ...

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 ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...

Growth, yield, and yield component changes among old and new soybean cultivars
Soybean [Glycine max (L.) Merr.] yield has increased at a rate of 25 to 30 kg ha–1 yr–1 due in part to improved genetic gain, and has been further advanced by the addition of resistance to soybean cyst nematode (Heterodera glycines Ichinohe; SCN) in new cultivars. The objective was to determine specific growth changes that explain the yield improvement from old to new cultivars and the further ...

Metalexyl fungicide induced oxidative stress and apoptosis in mouse thymus: the effect of antox
Metalaxyl is a benzenoid fungicide used to control soil-borne fungal diseases on fruits, cotton, soybean, peanuts, ornamental and grasses. The present work aims to evaluate the effect of oxidative stress on the induction of apoptosis in thymocytes of mice by metalaxyl. The work extends to study the possible role played by antox in minimising the toxicity of metalaxyl. Thymus of metalexyl-treated ...

A southern root-knot nematode resistance QTL linked to the T-Locus in soybean
Southern root-knot nematode [RKI; Meloidogyne incognita (Kofoid and White) Chitwood] is an important soybean [Glycine max (L.) Merr.] pest. When RKI resistance was introgressed from the highly resistant, gray pubescent breeding line G93-9009 into moderately resistant, tawny pubescent cultivars BoggsRR and BenningRR, higher than expected proportions of two advanced backcross populations had gray ...

Six Late Harvest Tips: Don’t Leave yourself Out in the Cold
One of the big concerns this harvest has been the moisture and rain that delayed the planting of corn and soy. Now, as we get into colder and colder temperatures and the stretches of intense sunlight begin to dwindle, some farmers might wonder how they should change their approach to the season. I’m a research lead for The Climate Corporation at one of its research farms in South Dakota, ...

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) ...

The Safety of Genetically Modified Foods Produced through Biotechnology
Executive Summary The Society of Toxicology (SOT) is committed to protecting and enhancing human, animal, and environmental health through the sound application of the fundamental principles of the science of toxicology. It is with this goal in mind that the SOT defines here its current consensus position on the safety of foods produced through biotechnology (genetic engineering). These products ...

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 ...

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, ...

Light Spectras and Absorption Curves for horticulture
When we talk about plants and their interaction with light, we mostly talk about photosynthesis. But this is only a small part of the story, there are numerous other mechanisms controlled by light. This article aims to help understanding the different mechanisms. Due to the complexity, we just give an overview of the interaction of absorption spectra. It is important to ...

Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...

Why do farmers pick poultry feed pellet making device?
As increasingly more farmers make use of chicken feed pellet making equipments, several farmers that have been breeding for more than 10 years start to have several troubles. As an example: why would certainly you make use of a poultry feed pellet making machine? Our town basically types meat rabbits, as well as the outcome is not particularly big, however nearly every family ...

What is the outcome of floating fish feed making equipment?
What is the result of the floating fish feed making machine? Is it costly? For small farmers and also specific family farmers, a new drifting fish feed extruder maker can be taken into manufacturing, since several farmers can not make use of commercial power at home, and the majority of them generally make use of household illumination electrical energy. When picking drifting ...
