Aim Herbicide on Sweet Corn:

John Masiunas, Univ. of IL

Aim (active ingredient carfentrazone-ethyl) herbicide manufactured by FMC can be used for postemergence weed control in either fresh market or processing sweet corn. Aim should be applied to actively growing weeds up to 4 inches high and rosettes less than 3 inches across. Aim at 0.5 fluid ounces (0.008 lb active ingredient)/ acre will control common lambsquarters, ivyleaf and pitted morningglory, eastern black nightshade, redroot pigweed, velvetleaf, common waterhemp, and tall waterhemp. Thorough coverage of the weeds is essential for control. Thus, a nonionic surfactant at 0.25% v/v with at least 80% active ingredient should be included in the spray solution.

Please NOTE for Ohio: The user assumes all responsibility for crop injury. Not all varieties of sweet corn have been tested for tolerance--check with your seed company or Extension specialist before use. Do not tank-mix with EC formulations of other herbicides.

Increase Marketability and Safety of Your Produce: Ohio Specialty Crop Food Safety Initiative is Free Resource

John Wargowsky

The primary objective of the Ohio Specialty Crop Food Safety Initiative is to increase the marketability and safety of the produce grown by Ohio fruit and vegetable growers. The effort has already reached over 200 fruit and vegetable growers and over 20 extension educators/crop consultants through educational seminars and workshops in Ohio. More growers are being reached through articles in trade publications and this spring, summer and fall will commence the on-farm component of the initiative.

They key educational content of the initiative is good agricultural practices for fresh fruits and vegetable that are designed to minimize microbial contamination on the farm. These practices are based on guidelines published by the U.S. Department of Health and Human Services and the Food and Drug Administration in "Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables." Links to both can be found at www.midamservices.org by clicking on projects.

Mary Donnell, Extension Agent with the Ohio State University Agricultural Business Enhancement Center is the education coordinator for the initiative. Mary Donnell will work with Francisco Espinoza of the Ohio State University Ag and Hort Labor Education Program to conduct Spanish speaking worker training primarily in the area of worker hygiene and sanitation.

Shari Plimpton with the Center for Innovative Food Technology is the food safety educator for the initiative. Shari has presented at the Muck Crop School, Ohio Fruit and Vegetable Growers Congress, Fruit Growers Marketing Association Information Meeting, Berry School and Ohio Fruit and Vegetable Food Safety Workshop.

Shari is also working with fruit and vegetable growers on their farms to assist in identifying and implementing good agricultural practices. These consultations are free of charge to the grower and can range from a couple of hour visit to a full consultation that prepares a grower for a third party food safety audit. During consultations, Shari will review pre-plant, production, harvest and post harvest handling practices. Growers needing to develop a food safety plan for purposes of a third party audit can also receive this assistance.

This initiative is financed in part or totally through a grant from the Ohio Department of Agriculture, the State of Ohio and the United States Department of Agriculture under the provisions of the Specialty Crop Grant. Mid American Ag and Hort Services is responsible for administration of the grant.

Agricultural Law Fact Sheet Index

R. Precheur

Producing a vegetable crop from seed or young transplant to a successful harvest seems to be the least of all concerns for the modern day vegetable grower. A majority of time can be diverted to other issues indirectly related to vegetable growing but just as important as the growing of the crop itself. These involve such issues as labor management, workman's compensation, food safety and compliance with all pesticide regulations. As more and more vegetable growers move to entertainment farming and fall festivals and 'Pick Your Own' operations remain popular, there are many things to consider to avoid future problems. I recently saw a notice for a new Ag Law fact sheet and at the same time found an index of several Ag Law fact sheets. These fact sheets provide some basic background on several important topics. They are available from your local county extension office or at the Ohioline website, (see the URL address and list of fact sheets, below).

Crop Reports April 22, 2003

Hal Kneen

Vegetable planting (especially tomatoes) has been put on hold as daytime temperatures reach only into the 60's and night time temperatures hover around 40-45 degrees Fahrenheit. Coldest weather is to be Wednesday morning with a gradual warming trend into the weekend. Received some welcome rainfall Sunday night, 6 tenths of an inch and promise of more on Friday. Growers are continuing to form raised beds covered with black plastic for intended tomato, pepper and melon crops. Tomatoes planted last week are looking good and rooting in well.

Sweet corn is emerging well from early April bare soil plantings.

Tomato growers are seeing pressure from re-wholesalers and brokers to move away from traditional ten pound tomato baskets into one layer flat packaging.

No potato beetles spotted yet. However, corn flea beetles have been spotted on sweet corn during the late afternoon hours, when its warmer.

Cabbage transplants are growing rapidly. Few cabbage butterflies spotted, so caterpillars are still few and far between.
