| no fungicide was applied last yr. It isn't a chemical issue from yrs prior. We are in the process of tissue and herbicide samples. Learning what happened and how is my main objective. On a 350 ac field we sprayed on tank load of antares prime and rest with compensa and it is right to the mark. Have 2 fields that boarder one another, one with straight sulfetrizone vs compensa, night and day difference. If we had heavy residue with stocks and trash, they did struggle more. We came to the assumption that soil was colder, seeds pry didn't take off as well and were more susceptible once stressed. Definitely took some population in those areas. Then you ask yourself, drilled vs planted soybeans. Well, we do both. Planted do seem as though they handled it somewhat better, but not by a lot. Most planted are on winter wheat stubble compared to drilled being on corn stalks. We do have a better plant stand on w/w stubble, which is expected with a planter. As of now, we determined there is nothing we can do except hope for sunlight. They look 2x better this week, but 5x behind other beans now. We know they will be short, major yield loss is expected. | |
