1, protecting natural enemies such as ladybugs, syrphids and grass ridges is also an effective control method.
2. When aphids occur in large quantities, 50% malathion EC 1000 times, 50% chlorpyrifos WP 1500 times and 40% monocrotophos EC 1500 times are selected for spraying. You can also spray 1000- 1500 times dimethoate or dichlorvos.
The earliest written record of Zanthoxylum bungeanum is in the Book of Songs. The Book of Songs is a collection of folk poems in the Western Zhou Dynasty, from which we can see that Chinese people used pepper more than 2,000 to 3,000 years ago.
Ancient people thought that the smell of pepper could ward off evil spirits. In some dynasties, the court used pepper to penetrate paint to paste walls. This house is called "Pepper Room" and is for ladies-in-waiting. Later, comparing the pepper room with the sentence "After the pseudo-discussion" in the sixteenth chapter of the Collected Works of Cao Cao and A Dream of Red Mansions, it is enough to prove that the quasi-pepper room enters the palace early on the second and sixth day of each month.
