Crop spraying need to pay attention to what, crop spraying precautions
The upper and lower surfaces of leaves, fruits, branch tips, and branches inside and outside the canopy should be sprayed. To do this, one way is to spray from the inside of the canopy first, especially if it's a large tree - reach inside the canopy with the nozzle and move it slowly, then move it an even distance around the tree, trying not to miss any sprays.
For the surface of the canopy, spray by walking slowly and methodically along the edge of the fruit tree. Move from the side of the hand holding the spray gun, the spray gun diagonally to the fruit tree spraying (not straight to the center of the fruit tree). While walking around the tree, move the spray gun from the base of the canopy up to the top of the canopy at an even speed, then move it down at an even speed, and repeat this operation continuously. After a circle around the tree, turn back to the opposite direction to repeat this step. In short, operate in a manner that facilitates full coverage of the liquid solution to the surface of the plant.
At the same time, continuous agitation of the liquid in the drum (box) during spraying is necessary to ensure that the liquid is well mixed. When using oil emulsions, it is important that the solution not be left to stand for more than 10 minutes. If it is left for more than 10 minutes, the fluid should be agitated well before spraying continues.
