After a year of plant or high water, farmers are still struggling with the repercussions of late planting outcomes. One thing farmers who planted late should expect is an increase in diseases and insect pressure during critical growth stages.
In an interview with Nathan Popiel, a North Dakota-based Agronomy Service Representative for Syngenta, he says soil borne illnesses will be at an all time high this year. Cold, wet weather in the beginning of planting has caused soybean fields to be more susceptible to Pythium and cerium. Heading into warmer, drier conditions, on top of already late planting, producers could be faced with diseases like Rhizoctonia and phytophthora. Both disease which can be devastating to soil and soybean plants. Phytophthora in particular, sets on late killing already established soybean plants.
This year, aphids are already showing up on the map. Popiel says it will be interesting to see how the movement of those pests moves through. A big concern regarding aphids is smaller, fragile plants. This is something farmers are seeing more this time of year compared to a year ago. Aphids are more likely to impact smaller soybean plants simply because of the small plant mass aphids have to feed off of. Ultimately, that means a higher percentage of the plant is being affected.
