A) Oda Issues Bulk Fertilizer Regulations For On-Farm Storage - La Barge CORN Questions

For the next five years there will be a distinction between farmers who have to follow the Bulk Fertilizer Regulations and those who do not have to follow the regulation. Farmers that have existing tanks with storage capacity over 5,000 gallons and store for more than 30 days will have from now until January 1, 2007 to install secondary containment around their tanks. The bulk fertilizer rules will not apply to them until January 1, 2007. Farmers who build a fertilizer storage facility of over 5,000 gallons or who add on to existing fertilizer storage tanks (with a total of 5,000 gallons capacity or more) and store for 30 days must follow the regulations and place tanks within a secondary confinement.

In addition to building secondary containment the Bulk Fertilizer Regulations also define inspection schedules and standards that must be followed. These are the same rules currently in place for non-farm facilities that store more than 5,000 gallons of fertilizer for more than 30 days.

For more information on Bulk Fertilizer Regulations contact Bill Goodman, Feed and Fertilizer Section, Ohio Department of Agriculture at 614-728-6397.

B) Fungicide Seed Treatment Research 2001 - Beuerlein CORN Questions

Soybean diseases in Ohio have increased in number and severity over the past 10 years, so that today the loss of productivity is greater from disease than from any other factor except weather. The increase in disease pressure is due primarily to short crop rotations or no crop rotation. It is estimated that Ohio soybean producers lose an average of five to eight bushels per acre per year to disease. In most years, few disease symptoms are recognized due to low levels of infection by any particular disease. However, several diseases are active in each field most years. It is noteworthy that by the time symptoms of a particular disease appear, the yield loss has already reached seven to ten percent. In many fields there is significant yield loss to disease even though no symptoms are evident.

In the past, we have relied on disease resistance and tolerance to provide some measure of control. Many of the Phytophthora control genes are no longer effective because the pathogens have evolved and can overcome the plant's defense mechanism. During the past ten years, fungicide seed treatments have been used effectively to improve soybean stands and increase the general health of soybean root systems.

In 2001 a series of soybean fungicide seed treatments and soybean fungicide seed treatments plus inoculation materials were evaluated at six sites in Ohio. Products used in the test were Stiletto, Rival plus Allegiance FL, SoyGard with Protégé, Warden RTA, ApronMaxxRTA, Cell-Tech 2000 and Celltech EXP. The untreated check yielded 56.9 bu/A and the average treatment yielded 58.6 bu/A. Stiletto, Rival plus Allegiance FL, SoyGard with Protégé all yield significantly more than the check (LSD 0.3) for the six site average.

C) Crop Production Conference Proceedings On-Line - LaBarge CORN Questions

The Crop Production Conference held January 11 is history but the information from the program is still available. The proceedings from this conference have been posted at http://corn.osu.edu/2002cornpc.pdf. Fertility management issues, weeds disease and insect updates as well as other industry topics were a part of this year's conference.

D) Great Websites For Forage Performance Data - Sulc CORN Questions

There are several excellent websites where you can find performance data for forage varieties. The best place to start is at our own Ohio Forage Performance Trial website, at http://www.ag.ohio-state.edu/~perf/.

Click on the forage report for 2001 to see our Ohio data for alfalfa, red clover, and cool-season grass variety trials. Also at the table of contents page of the 2001 Ohio Forage Report, near the bottom of the page, you can find links to performance trial data from other states across the country (http://www.naaic.org/Resources/yields.html).

Another link shown on the Ohio Forage 2001 site, is an excellent website at http://www1.uwex.edu/ces/ag/alfalfa/ This site was developed by the University of Wisconsin to compare alfalfa variety performance in university trials across 10 states and Ontario. On this website, you can specify your own criteria for performance comparisons and summaries, including: what year(s), what state(s), and which two varieties you want to compare. Based on your selected criteria, a summary will be generated for each variety compared to the trial average (by age of stand). If the two varieties you selected were tested side-by-side in the same trial(s), it will generate a summary of those head-to-head comparisons across the years and states you specified in your criteria selection. Data through 2000 has been loaded into that database. The 2001 data should be loaded into the database in the near future.

E) What Are All The Complaints About At Oda? - Folck CORN Questions

The Ohio Department of Agriculture released their summary of complaint pesticide investigations for their fiscal year 2001. These were investigations done after formal complaints were filed with the department.

Structural pest (including termite problems) led the complaints list with 113 filed. Second place belonged to agriculture with a total of 46 complaints. Drift complaints were the leading cause of agricultural inspections, with site damage a distant second. Turf and ornamental complaints numbered 30 during the year and industrial vegetation rounded out the top inspections with 21 complaints.
