NE Iowa | Better to spray it sooner than later, will be putting flowers on very soon, I d say to get the Cobra on before too long. Watch the air temp and humidty on the day you spray, will get significant more burning if humid and hot. You want the sum of the air temp and dew point to be less than 110 I believe.
Also, 4 oz will kill a lot of weeds and suppress white mold but not set the beans back as badly | |
