NE Ohio | I checked soybeans yesterday and noticed a fair amount of aphids on the top leaves. I didn't spend time counting the entire plant, but there was at least 100 - 150. I would estimate the beans are R4/R5 stage. Had some rain during the night, and calling for more later today. Has been dry and the next 10 days have temps in the upper 80's with a slight chance of rain again later this week. Spray boom is only 45', so I was wondering at this stage of development, will I save enough bushels to justify what I will run down with the sprayer? Any thoughts are appreciated. | |
