Give pepper aphids a pesticide, what medicine is effective?
There are many pests and diseases in Zanthoxylum bungeanum, so it is more and more difficult to control them. At first, there were fewer pests and diseases in pepper. At that time, Zanthoxylum bungeanum was really easy to plant and manage, only paying attention to fertilization and picking. The prevention and control of pests and diseases is very simple, and the number of drug use is very small. In recent years, there are many diseases of Zanthoxylum bungeanum. Let's talk about the harm of aphids to the buds, stems and leaves of Zanthoxylum bungeanum. The leaves of Zanthoxylum bungeanum will curl and deform due to the sucking of aphids, which seriously affects the photosynthesis of Zanthoxylum bungeanum leaves. At the same time, aphids secrete a special viscous liquid, which will cause damage to pepper leaves.
In fact, in my opinion, this kind of pests and diseases are mainly caused by preventive work in the most "weak" period, usually after autumn, before winter and before early spring. This pepper tree, which is very similar to the time and method of controlling apple tree diseases and insect pests, can not only repel aphids, but also aphids like the taste of pepper trees very much. Aphids begin to migrate to Zanthoxylum bungeanum every spring to breed offspring and absorb the tender leaves and buds of Zanthoxylum bungeanum. The harm is quite serious, and it can even make peppers fall without harvest.
The harm of aphids mainly lies in its rapid reproduction and great harm. If it is found a few days later, it is likely that aphids will become a disaster and suffer heavy losses. Aphids mainly suck the juice of new leaves when trees just sprout in spring, which makes the leaves curl and shrink, leading to leaf withering. Taking medicine in advance is the key. Aphids are very resistant to drugs, especially in some pepper orchards where aphids occur all the year round, which is more difficult to control. It is best to choose efficient pesticides and kill them in the early stage or before to reduce the population base.
