How does boom sprayers get fungicides to reach undersides of leaves
Since I read about the importance of covering the entire plant surfaces when using contact fungicides like mancozeb, I have been wondering how boom sprayers will achieve that. Doing it manually is a task unimaginable if you have 100s or 1000s of plants. Pls how can it be achieved?
I think they use pressurise air to assist it. The air 'atomize' the fungicide solution and help it to cover the entire plant. They also use large volume of water and nozzles set to direct sprays above and under the leaves.
Thanks. Africans still have a lot to learn wrt farm technology.
