Plant Management Network: journals and more





UW-Madison is a partner of the Plant Management Network, managed by the American Phytopathological Society, American Society of Agronomy, and Crop Science Society of America.  Students, staff and faculty have full access to the site, including:

Plant Health Progress - peer-reviewed journal focusing on plant protection; covers plant disease, entomology, and nematology of crops and ornamentals.

Crop Management - peer-reviewed journal covering crop management practices, crop nutrients, and production agriculture; focuses on maximizing crop yield and value.

Forage and Grazinglands - peer-reviewed journal covering animal nutrition and rangeland management.

Applied Turfgrass Science - peer-reviewed journal covering the many aspects of turfgrass management.

Plant Disease Management Reports - More than 5,000 searchable efficacy reports on various means of pest control, such as fungicides, nematicides, and biological controls. PDMR’s purpose is to help users determine the most effective chemicals and nonchemical pest management agents and to ensure maximum effectiveness/minimum use in terms of application. Reports cover various crops, ornamentals, turf and forage.

Arthropod Management Tests - Efficacy reports of insecticides and other means of insect control. Helps users determine the most effective chemicals and brands in managing insects and also to ensure maximum effectiveness/minimum use in terms of application rates. Reports cover crops, ornamentals, turf and forage.

Symposium/Meeting Proceedings - A collection of proceedings on topics related to agriculture and horticulture.

Focus on Soybean - An online portal for growers, crop consultants, and researchers seeking information on producing healthy, high-yielding soybean crops. Features webcasts from noted extension agents on soybean crop production, protection, and management.

Focus on Potato - An online portal for growers, crop consultants, and researchers seeking information on producing healthy, high-yielding potato crops. Features webcasts from noted extension agents on potato crop production, protection, and management.

Focus on Ag Practitioners - A one-stop portal of agricultural resources for certified crop advisers, independent consultants, and other ag practitioners.

PMN Image Collections - A collection of more than 4,000 plant disease and agricultural images for disease identification, class illustrations, and presentations.

New soybean pest: Trochanter mealybug

Infestations of the trochanter mealybug (Pseudococcus sorghiellus, in the Order Hemiptera, Suborder Homoptera, Superfamily Coccoidea and Family Pseudococcidae), an unarmored scale insect, were first identified in Midwestern soybean crops in 2008.  They can be found on the roots of soybeans that appear to be suffering from potassium deficiency (yellowing of the leaves).

Organic vs Conventional Production: Wisconsin Integrated Cropping Systems Trial


Researchers performing long-term agricultural studies in Wisconsin conclude that "...organic systems were more profitable than the Midwestern standards of continuous corn, no-till corn and soybeans, and intensively managed alfalfa" while "rotational grazing of dairy heifers was as profitable as the organic systems."

Further, "...organic forage crops can yield both as much dry matter as their conventional counterparts and with quality sufficient to produce as much milk..." and organic corn, soybean, and winter wheat "can produce 90% as well as their conventionally managed counterparts..." with weed control being a problem on average in one out of three years, and production being almost identical in two out of three years.

Top 100 Plant Science Questions


"How can plant scientists change the world?"

Initiated by researchers in the School of Biological Sciences at the University of Bristol, "100 Plant Science Questions" invites submissions of pressing plant-related research issues facing the world today. Deadline: March 31st, 2009.

A panel drawn from academia, the public services sector and the corporate world will screen submissions.

From the website:

"Plant science is helping to address many of the big issues facing society today, such as food security, biofuels, and the effects of climate change, but what are the key questions that you think the next generation of plant scientists should be addressing?

Anyone is welcome to contribute their question, including members of the general public; agriculture, horticulture and forestry industries; ecologists; charities; policy makers; food, fibre, fuel and pharmaceutical industries; funding bodies; and researchers."
