2. The solution drips onto the leaves or growing points, or a wide-mouthed container is used to hold the solution, and after use it is not covered, so water evaporates and the concentration becomes too high;

3. A substandard fruit-setting product made with 2,4-D as the main ingredient was used;

4. Repeated spraying when applying fruit-setting solution;

5. When dipping flowers or spraying the solution, the temperature is too high, the water evaporates away, which indirectly increases the concentration of the solution.

So when dipping zucchini flowers, do not use too much solution, and operate carefully to prevent the solution from dripping onto the leaves, growing points, and flowing onto the main stem; after each flower dipping, cover the container tightly to prevent the concentration from increasing due to water evaporation; insist on choosing qualified products produced by legitimate manufacturers and refuse to use inferior products; for new products that promote fruit setting and have not been used before, be sure to ask clearly about the concentration, method and precautions, then try them out, and only decide to use them on a large scale after the results are good and you have mastered the method of use.
