S PRAYER C LEANOUT

S PRAYER C LEANOUT � Has always been important but even more so now. � “Hot” burndown trts. because of Rs weeds. � Wide variety of crops and pesticides on a single farm. � GMO & Conv. side by side or on same farm. � Products sometimes active at very low rates. www.uaex.edu - search for “2170” in publications

T HERE ARE MANY PLACES RESIDUES CAN REMAIN IN A SPRAYER � Tanks � Hoses � Filters & screens � Nozzles & nozzle bodies � Ends of the boom

T ANK -C LEANING A GENTS � Commercial tank cleaners – often label recommended. Good for water and oil soluble products. � Ammonia – effective at penetrating and loosening deposits/residues. Does not deactivate pesticides but can increase solubility. � Chlorine bleach – Sometimes recommended for tank cleanout. Can deactivate residues. Corrosive and hazardous when mixed with ammonia (includes some fertilizers). ALWAYS READ THE LABEL

S URFACTANTS CAN ACT AS UNINTENTIONAL CLEANERS : � Certain surfactants can be very effective at removing residues from tanks, hoses, and strainers. � Growers in Arkansas have had problems when switching from growth regulator herbicides (2,4- D, triclopyr, dicamba) to post emerge applications of other products in soybeans and cotton. The surfactant used in the post emerge application was probably the reason.

F AMILIARIZE YOURSELF WITH THE POTENTIAL PROBLEMS FOR YOUR CROP & CHEMICAL COMBINATIONS . T AKE THE TIME TO THOROUGHLY CLEAN YOUR EQUIPMENT WHEN THE POTENTIAL FOR PROBLEMS IS HIGH . D ON ’ T FIND OUT TOO LATE THAT THE SPRAYER SHOULD HAVE BEEN CLEANED BETTER .

R E : THE VIDEO � The video was filmed in early July 2013 near Piggott, Arkansas, in Clay County in the NE part of the state. Andy Vangilder is the Staff Chairman for Clay Co. � Andy has been reporting problems with sprayer cleanout for a couple of years. � The primary crops in that region are GMO and conventional varieties of cotton, rice, corn, and soybeans.

R E : THE VIDEO � We spoke to several farmers about the problems they had with sprayer cleanout. � Andy also took me by a cotton field that had been damaged by herbicide residues from a sprayer that had no been sufficiently cleaned.

R E : THE VIDEO � Other growers had problems with flushing the booms and had worked on solutions too. � John Deere dealer was reported to be offering kits (for a price) to remedy boom cleanout problems. � We will conduct 2-3 sprayer cleanout clinics for farmers and applicators in November 2013. Bob Wolf will be helping with the effort.

R E : THE VIDEO � Sorry about the wind noise in parts of the video. � The framing on some of the shots is a bit off too because I didn’t want to make the farmers nervous by sticking the camera in their face.
