Even as two new weed control technologies are on the horizon for Mid-South agriculture, regulatory challenges continue in the process of getting federal approval for crop chemistries, says John Campbell.

“Things we were able to previously get approved by the Environmental Protection Agency, we may not be able to get today, even when we point out specific examples that they granted five years ago for other products,” he said at the annual meeting of the Mississippi Boll Weevil Management Corporation and the Mississippi Farm Bureau Federation Cotton Policy Committee.
Campbell, who has served as director of the Mississippi Department of Agriculture and Commerce’s Bureau of Plant Industry for the past four years, has recently been named deputy commissioner for MDAC.
The Bureau of Plant Industry, a regulatory and service division of MDAC, is charged with protecting the agricultural and horticultural interests of the state from harmful insects, diseases, and weeds.

With the new dicamba and 2,4-D technologies expected to be available in 2016, requirements for their use will be more stringent than for current restricted use chemistries, Campbell says.
“In December 2012, Commissioner of Agriculture Cyndi Hyde-Smith named a special focus group, composed of five farmers, to research these technologies and make recommendations to the Bureau of Plant Industry board for measures to be considered to mitigate the risks associated with the introduction of these technologies, and to formulate ways to use them safely and responsibly.”
In January 2015, after many meetings with the companies involved, recommendations were submitted to the board, Campbell says. “The board accepted them, and based on what we know today, this is the plan for these technologies when they hit the market:
“Before growers can use these technologies, they will have to complete an MDAC-approved training course. Mississippi State University is in the process of developing an online module to address issues such as off-target movement, volatility, tank cleanout — everything associated with these products.”
24/7 online training planned
The module will be available 24/7 for farmers to go online and complete the training, Campbell says. “This will be a requirement on the 24-C label — that this training must be successfully completed before these products can be used.
“You also will be required to keep records of your applications of these products for two years, and you also must keep sales receipts for the products for two years. Further, no applications can be made in winds exceeding 10 mph.
“These requirements are consistent with those for our restricted use products, except for keeping sales receipts. It’s also current regulation that seed dealers keep records of name, variety, lot number, amount sold, etc., so their information can be accessed if needed.”
Droplet size is important in reducing drift, as shown in this display.
The farmer panel also recommended that programs be made available to offset the cost of equipment to reduce drift, such as hooded sprayers, nozzles, etc. But, notes Campbell, “That is only a recommendation to the board, and isn’t mandated by MDAC.”
Three years after the technologies are in use, he says, “We will measure the effectiveness of the program and decide if changes are needed. A lot of time has been spent on this — we know these technologies are needed by our growers, and we also know there are challenges and risks associated with them. We need to be good stewards of these technologies if we’re going to keep them long term.
“We hope this education and training requirement isn’t burdensome, and that it will be helpful in making sure that these technologies will be around for a long time.”
This is the second year, Campbell says, for a Section 18 permit for Transform for control of the sugarcane aphid, and Bayer has also obtained registration for its product, Sivanto.
