Weather now to mid-April

The graphics show the greatest chance for at least 2" of rainfall for the next two weeks is across the southern half of Ohio, most of that is before April 1. 

 NAEFS Rainfall

The temperature outlook is for the first week of April. Hence, it will turn a lot warmer the middle of next week into the first week of April. 

NAEFS Temperatures

We will be getting our new climate model runs for the spring into summer this week and will pass on that information when we get it. There is some indication of a major swing in the pattern as we go into summer (possibly toward warmer and drier conditions) so stay tuned.

Weed Control Guide reminder

As we made the rounds this winter we heard several requests for more details on weed management in Ohio. Several counties made the Ohio and Indiana Weed Control Guide available at their pesticide applicator training sessions as part of the registration. As we prepare to deal first with weed control in wheat, and then for those no till burndown situations, we wanted to remind you again of the resource available from the Weed Science group at OSU and from your local county Extension office.

The “2010 Weed Control Guide for Ohio and Indiana,” which sold out of its initial run in just three weeks, is again available for farmers, crop consultants or anyone else in the weed control business looking for tips.

Written by Ohio State University Extension and Purdue University Cooperative Extension weed specialists, the 192-page publication provides research-based, unbiased weed control recommendations. It covers such topics as the importance of timing, proper identification, cultural and mechanical control, spray drift, weed resistance and sprayer calibration.

Other highlights include:

* Detail on no tillage, pre-emergence, post-emergence and combination herbicide programs.

* Detailed advice for conventional corn (Non-GMO) as well as Clearfield, Liberty Link and Glyphosate-Resistant hybrids. Similar recommendations are outlined for Non-GMO, Roundup Ready and Liberty-Link soybeans.

* Weed control strategies for wheat and oats, including those underseeded with legumes, with a special page illustrating wheat growth stages relative to the timing of herbicide application.

* A harvest aid area that addresses products utilized for that undesired scenario in corn, soybeans and wheat.

* For farmers who grow forages, check out the section that covers legumes, grasses and pastures.

* A dozen pages review the control of problem weeds like giant ragweed, thistles, dandelions and pokeweed.

 

The publication, Bulletin 789, can be ordered at OSU Extension’s e-store: http://estore.osu-extension.org/productdetails.cfm?PC=2229.  The cost per copy is $10 until 4/1/10 when the price is expected to increase. The publication is also available in a PDF format through the OSU Weed Science Web site at https://agcrops.osu.edu/weeds. Also available on the weeds website are the Marestail Control videos – produced in multiple formats and both a long and a short version. You’ll also find tips on control of several other weeds there such as:

Giant ragweed

Lambsquarters

Cressleaf groundsel

And information on controlling herbicide resistant weeds. 

 

Pesticide Applicator License Clarification for Treating Seed

1. If an applicator does not own the seed that he or she is treating with pesticides, he or she is treating the seed for hire, and therefore required to have a Pesticide Business License and a Commercial Applicator License with category 2D. It is also required that application records are kept for all of these pesticide applications. If the applicator does not apply any other pesticides for hire, no proof of insurance is required for the business license. For example, if a farmer brings a wagon load of seed to an applicator and he or she treats it with pesticides prior to planting, both licenses mentioned above are required. Pioneer seed dealers fall into this category because they are not employees of Pioneer and do not take ownership of the seed from Pioneer.  Other seed companies may also fall in this category.

2. If an applicator owns the seed as a seed dealer or farmer and he or she treats the seed with a restricted-use pesticide prior to selling the seed or planting it, a Private Applicator License with category 12 or a Commercial Applicator License with category 2D is required. Application records are also required for all pesticide applications. A Pesticide Business License is not required.

3. If the applicator owns the seed as a seed dealer or farmer and he or she treats the seed with a general-use pesticide prior to selling the seed or planting it, no licensure is required. It is also not required by law that records are kept for these pesticide applications, but it may be a good idea to keep records for any potential liability claims.
