An article provides a detailed introduction on how to deal with white bugs on chili plant leaves, which is related to green plants and flowers. Let's find out more from the editor.
What to Do When White Bugs Appear on Chili Plant Leaves
There will be many small white bugs on the leaves and even the plants of chili, which are called whitefly. The adults and nymphs like to gather on the back of chili leaves to live, feeding on the sap of the leaves. In the early stage of whitefly infestation, you can use pesticides such as Pucel, Tiamul, Imidacloprid, or Matrine solution, spraying once a day in the afternoon for 3 to 5 consecutive times.
In the process of growing chili, it is often found that many small white bugs appear on the leaves, and even on the plants.
These bugs are special because they can not only crawl but also fly. When people enter the chili field, these small white bugs will fly around when disturbed and then quickly fall back.
1. Characteristics of Whitefly
Actually, these white bugs are called whitefly. Their adults and nymphs like to gather on the back of chili leaves to live, feeding on the sap of the leaves.
Whitefly have piercing and sucking mouthparts that can insert into the leaves,吸食 the sap, which can cause the leaves to turn yellow and eventually wither.
Whitefly have a high reproductive capacity. Originally only a few whiteflies, if not effectively controlled, it can be found that a large number of whiteflies gather on the back of leaves within a few days.
Whitefly can not only harm the leaves of chili but also cause the growth of chili plants to be unhealthy, severely affecting the yield and quality of chili.
2. Reproductive Characteristics of Whitefly
Whitefly can breed more than ten generations a year, but in colder northern regions, they cannot survive the winter outdoors. The low temperature can freeze the nymphs to death.
However, they usually hide in various greenhouses to survive and successfully overwinter, reaching a peak in July and August every year, with the density of bugs increasing.
Whitefly have small wings, which are conducive to their migration. After the temperature drops in September, they start to move to warm places like indoors to hide. This characteristic of whitefly is also one of the reasons why it is difficult to control during prevention and treatment.
3. Conventional Control Measures for Whitefly
There are many methods to control whitefly, usually involving the use of pesticides. For example, in the early stage of whitefly infestation, you can use pesticides such as Pucel, Tiamul, Imidacloprid, or Matrine solution, mixed according to the medication proportion, spraying once a day in the afternoon for 3 to 5 consecutive times.
If chili is grown in a greenhouse, you can adopt the method of fumigation. Use dichlorovos smoke bombs, add sawdust to ignite, and close the doors and windows to keep the room sealed, which also has a good effect.
However, due to the rapid reproduction of whitefly and their ability to fly, pesticide spraying and fumigation can only provide temporary control, and they will appear again afterwards.
4. Physical Control of Whitefly
Whitefly that cannot be controlled by pesticide spraying or fumigation can be managed by hanging yellow insect traps, which not only have good results but also make the control process convenient, reduce the input of pesticides, and avoid pesticide pollution and residue.
Since whitefly are sensitive to yellow, based on their attraction to yellow, place yellow insect traps in the chili field and coat them with a layer of sticky oil.
This can effectively kill whitefly, and the traps can also be reused, which can be called a "once and for all" method.
