Afla-Guard also protects corn crops

06.09.2010
Afla-Guard®, a biological control used to thwart the growth of fungi on peanuts, can be used on corn as well, according to a study by U.S. Department of Agriculture (USDA) scientists who helped develop it.

After extensive study and research trials in Texas, Afla-Guard® was registered by the U.S. Environmental Protection Agency (EPA) for use on corn, beginning with the 2009 crop.

Recently retired Agricultural Research Service (ARS) microbiologist Joe Dorner at the National Peanut Research Laboratory in Dawson, Ga., helped develop Afla-Guard®, a biological control for the aflatoxin-producing fungi Aspergillus flavus and A. parasiticus in peanuts. ARS is USDA's principal intramural scientific research agency.

A. flavus and A. parasiticus, naturally-occurring soil fungi, can invade food and feed crops, contaminating them with aflatoxin. Aflatoxin is a human carcinogen produced by the fungi and is also toxic to pets, livestock, and wildlife.

Afla-Guard® is composed of hulled barley coated with spores of a nontoxic strain of A. flavus. The nontoxic Aspergillus fungi successfully compete against the toxic species for the limited space and nutrients each needs to grow and thrive. In peanuts, Afla-Guard® reduced aflatoxins by an average of 85 percent in farmers' stock peanuts and up to 97 percent in shelled, edible-grade peanuts.

In light of this success, Dorner and other ARS scientists conducted a two-year study of Afla-Guard® in corn. They again found that it was effective in reducing aflatoxin levels—showing an overall reduction of 85 percent, when compared to control fields.

Afla-Guard® was applied to the corn crop in different ways: to soil when corn was less than a meter tall, in plant whorls prior to tassel formation, and as multiple sprays during silking.

Read more about this and other corn-related research in the September 2010 issue of Agricultural Research magazine.

The research was published in the Journal of Food Protection.

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
