Will nozzle kind remedy the issue of getting efficacy whereas spraying T3 fungicides? There’s loads of work achieved on the fitting nozzle for this job, however what are the opposite elements that result in an efficacious utility for controlling fusarium?
On this Wheat College episode, our resident agronomist Peter “Wheat Pete” Johnson is fired up and has some perception into what to concentrate to, in the case of spraying T3 fungicides.
First up is droplet size. Why do turbo floodjets do a greater job than ahead/again nozzles? As a result of they’ve a rough droplet size, says Johnson. A rough droplet will go farther than a nice droplet. Not solely does the droplet want to achieve the wheat head, it must additionally attain the back and front of the wheat head.
“We don’t think we want ultra-coarse or extra-coarse, because then we don’t have enough droplets to hit the head,” says Johnson. Additional to that, fogging it on will do a very good job of “painting” just one facet of the top, which is just 50 per cent efficacious, at the easiest.
Try the video for Johnson’s nozzle suggestion, his ideas on anti-drift brokers, and a superb analogy on droplet size, story continues under:
Spraying straight down on the right angle will scale back the gap the droplets must journey. Reducing the increase 10 to 12 inches off the cover, which additionally means lowering pace and fill time to get the identical quantity of acres achieved in a day.
The very last thing to consider is windy situations, says Johnson. “If you’re in windy conditions, and we typically talk about 10 kilometre an hour winds, but if you think about throwing that coarse droplet, if you’re throwing it into a gale force wind, the wind’s going to win,” says Johnson.
In fact, the fitting nozzles are necessary, however rigorously take into account all these different elements when spraying T3 fungicides.
