Caterpillars are a problem that small-scale and indoor growers do not need to worry about because caterpillars and spiral heartworms are too conspicuous and easy to handle. But when the scale of planting increases and the plants become thicker and denser, these worms can become tricky.
This kind of bugs can cause irregularities and uneven distribution of cavities in the leaves. They rarely damage the stems of plants. In small numbers, they only eat tender and juicy leaves.
They leave black spots after eating the leaves, which are their feces.
In addition to caterpillars, they attack hemp worms, as well as the larvae of other moths.
Solution
- Avoid the spread of adult insects, such as various butterfly moths. These insects look very beautiful at best, but they will spread eggs everywhere to prevent them from approaching your plants. The environment-friendly and pollution-free method is to use outdoor insecticidal lights.
- Abamectin. This medicine is very corrosive and has a good insecticidal effect. It has a strong killing effect on all kinds of insects, but it can also corrode the skin. When using it, you must protect the respiratory system and skin.
- Pyrethroid insecticides, insecticides with low spectrum toxicity, need to be used continuously.
- For poultry animals, put ducks, chickens, geese and other poultry in the fields, they will quickly eliminate most of the pests.
Generally speaking, these large-sized pests are not dangerous and difficult to control. They will not produce substances that are deadly to plants and can be avoided with a little attention.
