How to deal with the red spider mites on my flowers

Solution:

Spraying should be done at the right time. Spraying 1000-1500 times of 40% dicofol has a good insecticidal effect, but it is ineffective against insect eggs. Spraying with 0.3-0.5 degree lime sulfur mixture can kill insect eggs. Using 3-5 degree lime sulfur mixture during the dormant period of flowers and trees can kill overwintering female adults. Since red spiders mostly harm the back of leaves, when spraying, aim at the back of the leaves and pay attention to spraying the inner branches and leaves.

Red spider mites are a type of mite that can produce more than a dozen generations a year. They are especially harmful under high temperature and drought conditions. At temperatures above 30°C, they can reproduce a generation in about 5 days. They use their mouthparts to pierce the leaves and suck the juice, destroying the chlorophyll in the affected leaves. When the damage is serious, the leaves gradually turn yellow and fall off, and even all the leaves on the plant fall off, causing serious impact on growth.

This can eliminate the second generation of pests, and can also prevent and control piercing-sucking pests such as aphids, red spiders, and scale insects. Putting it into the soil can prevent and control maggots.
