Fungicides can ship a robust defence towards fusarium head blight (FHB) in wheat however how the product is utilized in-crop performs a key position in figuring out whether or not growers efficiently shield these invaluable wheat heads.
On this episode of the RealAgriculture Wheat School, Syngenta agronomist Brad Garlough shares fusarium software insights and finest practices gathered from analysis trials and dealing straight with growers. He says spraying for fusarium is generally the final go in a wheat discipline and it’s essential to successfully paint the wheat head and permit the fungicide to guard grain yield.
For Garlough, nozzle choice is a crucial choice for spray applicators. The sprayer mannequin and quite a lot of different elements will impression the nozzle alternative and it’s vital to do not forget that one dimension doesn’t match all. His best choice is a 3D nozzle that sprays back and front and alternates from side-to-side to make sure the product covers all the head. (Story continues after the video.)
The nozzle additionally performs a crucial position in producing the fitting spray droplet dimension. Over the final three years the largest shock Garlough has seen in his software work is the variety of growers who “fog on” fungicide at FHB timing. Unfortunately, too typically he sees a mixture of wind and sprayer pace that causes finer droplets to typically drift and miss the head. He notes that the proper nozzle will give growers the coarse and additional course droplets required to hit their goal.
In the video, Garlough shares analysis he performed this yr on why it’s so vital to think about wind pace when setting the strain stage on the sprayer. He’s a giant fan of water delicate paper and the way it may help fine-tune sprayer calibration. He demonstrates the way it can simply be used to evaluate sprayer efficiency and decide whether or not each the back and front of the wheat head is being adequately coated.
Garlough additionally supply recommendations on water volumes, sprayer pace, and the way growers can benefit from superior spraying know-how after they purchase new rigs coming market.
