Insect pests and their control of duyinghua

The main diseases of Du Yinghua are as follows: Copper Green beetle, mole cricket and ground tiger, red wax scale, inchworm and tea bag moth

Coppery beetle

The larvae of the Scarab will harm the roots of the plant and cause the death of the whole plant. Adults will eat the leaves and buds of plants, affecting the growth and beauty of spiders. The adults of the Scarab can choose insecticides or kill them. In addition, they can be lured and killed by light with the help of the phototaxis of the scarab

Mole cricket and earth elder

These two pests mainly harm the roots of plants. When these two pests appear, dichlorvos can be used for inspection and killing

Red wax scale

The red wax scale will suck the sap from the stems and leaves of the plant, and the excreted substances will cause the plant to suffer from coal pollution disease and cause the plant to wither. The important task of prevention and control is to pay attention to the gap between plants, pay attention to ventilation, and trim branches and leaves in time for destruction. In addition, the prevention method can spray drugs before the nymph hatches, cut down the pests from the root and control the number of adults

Tea bag moth

Tea bag moth will bite leaves, causing branches to die and affecting the external beauty of trees. The prevention and control measures can be manually removed, the branches and leaves can be trimmed in time, and the dead and diseased branches can be treated and removed in a centralized manner. In addition, drugs such as hypertonic abamectin EC and cypermethrin EC can also be sprayed to kill insects

Inchworm

In the face of Inchworm pests, we should choose the method of centralized killing. We can set plastic film bags on the trunk or spray insecticides directly. The male moth of Inchworm has phototropism, which can be used to trap and kill the male moth by light. In addition, blocking poison killing can also be carried out
