 PARAQUAT HERBICIDE TRIAL

 E. E. Albregts
 Associate Professor (Horticulturist)


Objective: To evaluate different paraquat application rates to bed middles for
control of weeds and to obtain residue samples of fruit.

Previous years results: If weeds are small (1-2 inches) at first application of
paraquat, weeds were fairly well controlled with 1/4 lb/acre rate. Row middles
were sprayed three times during season. The 1/2 lb/acre rate gave good weed
control.


1974-75 results to January 31: Weeds were not well controlled in the 1/4 lb/acre
rate plots especially if weeds were 4 to 5 inches tall before spraying. Best re-
sults have been with the 1/2 and one lb/acre rates.
