IPNI Joins PMN’s Partners Program

PMN welcomes the International Plant Nutrition Institute (IPNI) as its newest partner. IPNI is a not-for-profit, scientific organization dedicated to responsible management of plant nutrients for the benefit of the human family. It works to help define the basis for appropriate use and management of plant nutrients and to provide comprehensive and regional information and research results to help farmers, and the industry, deal with environmental and agronomic problems.

Plant Health Progress Editor's Pick

The corn earworm, Helicoverpa zea, is a highly mobile pest of numerous field and vegetable crops in much of North America. Historically, synthetic pyrethroid insecticides have been cost-effective and have provided excellent control of corn earworm. However, since 2000 pyrethroids have only provided 35 to 45% control. A symposium published this month, Increasing Concerns about Helicoverpa zea Susceptibility to Pyrethroids in the Midwestern USA, describes this issue, the impact on growers and processors, as well as alternative strategies for this pest.

PMN Introduces Cross Journal Search

Try your hand at the new journals search engine located under the “Resources” tab on the PMN navigation bar. The search finds only credible agricultural and plant science information from select applied journals. Said one user, “I tried the search for applied journals and it’s great!  This is important because Pub Med does not pick up applied journals." It joins the search engine for extension publications published by PMN’s partner universities, which is also located under the “Resources” tab below the Plant Management Network header.

New Disease Management Reports Added to PDMR

50 new efficacy trials for chemical and nonchemical means of plant disease control have been added to Plant Disease Management Reports, Volume 1, for a total of 571 reports. Access to the reports, as well as thousands of reports from past B&C and F&N Tests volumes, is available to subscribers and partners of the Plant Management Network. Subscription information is available online.
