Waterhemp Herbicide Plot Tour August 4 in Waterloo
Glyphosate-resistant (GR) weeds including waterhemp are an increasing concern for NY field crops. Growers and Industry representatives will have an opportunity to tour and observe effective preemergence and postemergence applied herbicides for controlling waterhemp in Enlist soybeans. Dr. Vipan Kumar, Cornell weed scientist, will lead the tour through the small plot treatments and discuss the impact of these integrated herbicide strategies, with multiple modes of action, from a resistance management standpoint. No cost, no reservations needed. Questions? Call Mike Stanyard @ 585-764-8452.
Where: SE corner of NY-318 and Whiskey Hill Rd., Waterloo (just west of J Martin Auctions, 1036 NY-318, Waterloo)
When August 4- 10:00 – noon
1.0 DEC Certified Applicator Credit will be available.
Scouting Tips Now that Corn is Beginning to Tassel
Some of our corn growth across the region has just exploded with the hot, humid and sometimes too wet conditions. I am starting to see some tassels starting to emerge. What pests should we be looking for right now? Tassels mean that silking is not far behind. Unfortunately, current weather conditions are perfect for diseases. It is a crucial time for scouting corn and determining if a fungicide application is warranted. Northern corn leaf blight (NCLB) and gray leaf spot (GLS) are two of our first diseases that can establish. Hopefully, you have planned ahead and planted hybrids with the highest level of resistance. Even though spores can move long distances, continuous cornfields and no-till fields with lots of corn residue are also the most vulnerable from local spore development and dispersal. Go to Cornell’s Field Crop webpage to learn more about both diseases, http://fieldcrops.cals.cornell.edu/corn/diseases-corn. We have not seen any Tar Spot in the state yet and I will talk more about it next week.
On the insect side, Western Bean Cutworm (WBC) should be emerging. The females like to lay their eggs in pre-tasseled corn on the topside of the top leaves that are still vertical. I have received pictures of WBC egg masses this week from Wyoming County. Larvae will briefly feed on the tassel and pollen before moving inside the corn ear. Remember, only plants with the Viptera Bt will have some protection from feeding injury. Threshold is 5% or greater of the plants with egg masses. Eggs will turn from white to purple as the larvae get ready to emerge.
Don’t Miss Out on the 2023 NY Corn & Soybean Yield Contests
The annual corn and soybean yield contests sponsored by the New York Corn & Soybean Growers Association are underway. The yield contest entry form and contest rules can be found here: https://nwnyteam.cce.cornell.edu/. Entry forms must be postmarked by August 30. Entries can be mailed to Ashley Knapp at Genesee County CCE, 420 East Main St., Batavia, NY 14020 or emailed to ak2367@cornell.edu. Questions: contact Mike Stanyard at 585-764-8452. Cost is $30 per entry. This year the overall corn and soybean champions win an all-expense paid trip for two to the 2024 Commodity Classic in Houston, TX.
Next report will be July 26.
