Control powdery mildew: 400 to 500 times of water spray with 1% osthole liquid.

Function Mechanism:
1. Insecticidal mechanism: Inhibits the insect acetylcholinesterase, affects the nervous system, causes the non-functional contraction of the insect muscle, and eventually dies.
2. Bactericidal mechanism: By inhibiting the absorption of calcium ions, it affects the growth and spore germination of the bacteria and inhibits chitin deposition of the bacterial cell wall.
3. Night moth egg: Dissolves the villi on the egg of the night moth and reduces the adhesion of the egg granules, leading to a decrease in hatching rate.
