Injury to navy bean ( Phaseolus vulgaris L.) by 2‐chloro‐2',6'‐diethyl‐N‐(methoxymethyl) acetanilide (alachlor) was observed at 20 and 25 C but not at 30 C. This injury was observed in the ‘Sanilac,’ ‘Seafarer,’ and ‘Gratiot’ varieties but not in the ‘Michelite’ variety. The herbicides S‐ethyl dipropylthiocarbamate (EPTC) and α,α,α‐trifluoro‐2,6‐dinitro‐N,N‐dipropyl‐p‐toluidine (trifluralin) did not injure the navy beans at 20, 25, or 30 C under the controlled environment of the experiment at rates up to twice the 3.37 and 0.85 kg/ha rates, respectively, used in the field. Navy beans were injured at all temperatures studied, 20 C, 25 C, and 30 C, by 3‐(3,4‐dichlorophenyl)‐ l‐methoxy‐l‐methylurea (linuron) at three‐fourths the rate used for weed control in soybeans [ Glycine max (L.) Merr.].
