Stop BYDV in wheat with aphid control
Get an insurance policy
Prevention is key with BYDV. Scouting aphids in the fall is an extremely difficult and lengthy process, and by the time aphids are spotted in a field, it’s likely the infection is present already, too. A grower’s best option is to prevent aphids from attacking in the first place with a quality seed treatment, according to Syngenta. The right seed treatment can protect cereal crops from fall aphid attacks and serves as a first line of defense against BYDV.
“You don’t know for sure if you are going to have an aphid or BYDV problem before the planting season. But, you do know that if you apply a seed treatment, you are virtually eliminating the risk,” said Jim Swart, extension specialist, Texas AgriLife Extension. “Seed treatments help ensure you don’t end up with BYDV. In effect, it is basically an insurance policy.”
Like any good insurance policy, a seed treatment offers full protection from yield-robbing insects from the moment seeds are planted, working systemically to protect plants as they grow. Even if there is little or no aphid pressure this fall, thiamethoxam active ingredient seed treatment has been proven to produce healthier, more vigorous plants.
This season, Syngenta is also suggesting growers can achieve added seedling protection with the right seed treatment fungicide, which is fully compatible with insect protection seed treatments and protect wheat and barley seedlings from diseases and insects at the same time.
A combination of three active ingredients--sedaxane, mefenoxam and difenoconozole--is in Vibrance Extreme fungicide, which protects against a broad spectrum of seedborne and soilborne diseases, explained Chad Shelton, seedcare brand asset lead, Syngenta.
Protect in the spring, too
Fall aphid attacks may be the most devastating, but aphids can cause significant damage in the spring, too. As the year goes on and spring emerges, growers should continue to be proactive against aphids with diligent scouting. If aphids are present, a foliar insecticide application labeled for aphid control may be warranted. The foliar insecticide used for spring aphid attacks should be able to be tank mixed with most herbicides and fungicides to save trips across the field, Syngenta points out. The company also says agronomists, consultants or growers should check with their state or local Extension office for aphid threshold level spraying recommendations in an area.
While the drought of 2012 may be keeping aphids at bay for now, fall conditions can change quickly into those favored by this yield-robber. At the start of the season, there needs to be time invested to protect wheat by delaying planting, eliminating the green bridge and scouting fields. Continued scouting in the spring, as the weather warms up, is necessary to keep aphids from causing major damage at this point, too. Ultimately, an integrated approach that includes scouting, sound management practices and quality seed treatments and crop protection products will help ensure a healthy, pest-free crop with maximum yield potential.
