When getting set to apply a fungicide to pulses and cereals, remember that disease prevention and suppression is your main goal.
Fungicides need to be applied on target in order to be effective, which is why you should keep water volumes and travel speeds top-of-mind.
Use the highest registered water volume while lowering your travel speed so you can be sure to get the most even consistent coverage over the entire crop.
Crop staging is another important consideration. On lentils, for example, you should get into the field before row closure in order to coat the plant stems with your fungicide spray for more complete protection.
By the time of your second fungicide application, that pulse crop will be fully canopied. This is where high water volumes can help distribute fungicide further down to the plant’s lower leaves and stems.
On cereals, choose spray equipment according to the crop and fungicide target. For example, twin nozzles that spray forward and backward can help you coat higher, smaller targets — like wheat heads — to increase your level of protection at fusarium head blight timing.
