Famous Predictions u“I think there is a world market for maybe 5 computers.” Thomas Watson, Chairman - IBM (1943) u“We don’t like their sound (Beatles), and guitar music is on the way out.” Decca Recording Co. (1962) u “640K ought to be enough for anybody.” Bill Gates (1981)

We have had a few good years!! u Cadre u Select u Strongarm u Valor u 22% of active ingredients since 1996 Not bad for a minor crop!!!!

What’s in the pipeline?? u not much. It is getting very dry. u Spartan u Cobra u Will they ever make it? u Do we need them?

What do the growers want/need? u cheaper weed control strategies u $25 weed control (Is it possible?) u Why? 4 r eductions in peanut price (2002 Farm Bill) 4 34% of operating costs spent on agri- chemicals

Where does that leave us? u make do with what we got u 18 active ingredients u new uses for older products u combinations u reduced rates u cultivation

The Peanut Weed Control Toolbox

New Uses for Older Products u currently PPI or PRE u What about POST? 4 bristly starbur 4 common ragweed 4 cocklebur 4 morningglory 4 others

Herbicide Combinations u compliment each other u lower rates 4 reduced cost 4 less carryover? u more research u different MOA

Hophornbeam Copperleaf Control Randolph County, GA WAT Untreated Strongarm (0.45 ozs/A) Valor (3 ozs/A) Strongarm ozs + Valor 0.75 ozs/A

Weed control in peanuts with reduced rates of Strongarm and Valor, Untreated Strongarm 0.45 oz/A Valor 3 oz/A Strongarm oz/A + Valor 0.75 oz/A Attapulgus, GA (7 WAP)

Reduced Rates u already being done u 50% price reduction did not stop this u we know it can work u not the answer to cotton rotations u Can we get better at it?

Response of Weeds to Various Cadre Rates in Georgia Webster et al Applied EPOST (C-2LF)

What about cultivation? u has been on the decline u depends upon fuel prices u twin rows? u strip tillage? u disease problems? 4 Abound/Folicur Source: UGA Extension Agent Surveys Peanut Cultivation

Herbicide Resistant Weeds u will get worse before it gets better u ALS resistance confirmed u probably have DNA resistance u continued/increased use of glyphosate u Do we have a plan?
