Protecting Corn from Soil Insect Injury
Whether economically viable or not, many producers use soil
insecticides, transgenic seed, or insecticide-treated seed as
insurance along with their corn planting. Reasonable performance
expectations and evaluation are discussed along with treatment
guidelines.
Cruiser Registered for Use on Soybeans
Annual application of insecticides to soybeans has not
traditionally been necessary or common. Do new pest threats
justify soybean seed treatment? The jury is still out while
sufficient data are being generated. Several online reference
articles are recommended.
Spring Moth Flights Have Begun
More black cutworm moths and armyworm moths were caught in
pheromone traps this week.
Getting Ready for Alfalfa Weevils
Guidelines for scouting fields for alfalfa weevils are provided,
along with online resources for identifying and managing the
pest and distinguishing it from clover leaf weevil.
Proliferation of Premix Products
Detailed tables list trade names, components, application rates,
amounts of active ingredients, and product equivalents for corn
and soybean herbicide premixes. A sample calculation
demonstrates how to convert an application rate as needed.
What Weed Is That?
Suggested references are described for identifying early-season
weeds, summer annual weed seedlings, and mature and flowering
weeds.
Does Corn Seed Size Really Matter?
Multiple researchers have concluded that seed size and shape do
not have consistent effects on seed quality. Though independent
testing of seed quality is available to producers, it rarely
identifies problems; the competitive economic environment helps
ensure that companies supply only top-quality seed.
Regional Reports
Reports are supplied this issue for northern, southern, and
west-central Illinois. |
