Abound and pyraclostrobin e. Headline were very effective at managing peanut rust. Treatments that had chlorothalonil e. Bravo and tebuconazole e. TebuStar also provided adequate rust management. However, only the chlorothalonil and pyraclostrobin treatments provided adequate late leaf spot management as well.
It is also important to note that farmers using the leaf spot fungicide Miravis will need to combine it with a fungicide that has additional activity on rust if it is present in the field. Be sure to pay attention to the preharvest interval for the fungicide products as they will typically range between 14 and 30 days.

When conditions are right, he or she drives a digger up and down the green rows of peanut plants.
The digger has long blades that run four to six inches under the ground. The plant is loosened and the tap root is severed. Peanuts contain 25 to 50 percent moisture when first dug and must be dried to 10 percent or less so they can be stored. They are usually left in windrows for two or three days to cure, or dry before being combined. After drying in the field, a combine separates the peanuts from the vines, placing the peanuts into a hopper on the top of the machine and depositing the vines back in the field.
Freshly dug peanuts are then placed into peanut wagons for further curing with forced warm air circulating through the wagon. Moving into this growing season, avoid planting peanuts in the same location peanuts were planted last year. Use soil moisture sensors to monitor soil water, and only irrigate when the crop calls for an irrigation treatment based on the sensor data.
Lastly, it is very important to start out with a strong fungicide program to treat emerging disease, as we have already begun the season with heavy moisture. Yellowing and browning leaf margins.
