Common diseases and pests of jasmine and their control methods

Diseases of brocade

Symptoms of charcoal blast on bromeliad

In the early stage of anthracnose, there are several brown spots on the leaf surface, which are distributed irregularly. In the later stage of the disease, the spots become darker and larger, turning into dark brown or black. The center of the spots is sunken, which is called the spore gathering area. The flower buds fall off and the tender shoots die.

Methods for controlling charcoal blast of hydrangea

Strengthen the management of the cultivation area, loosen the soil in time and remove dead leaves; plant at a reasonable density and strengthen ventilation and light transmission; soak the bulbs in copper sulfate solution for 30 minutes before planting, then wash with water, dry and then plant; spray 500 times diluted carbendazim wettable powder twice a month; if the disease has already occurred, use 2500 times diluted benlate for prevention and control.

Symptoms of rot disease

If the soil of the jasmine plant has poor air permeability or the environment is not well ventilated and light-permeable, the bulbs will easily rot, eventually leading to the death of the entire plant.

Methods for preventing and controlling rot of jasmine

Reasonable density of planting can increase ventilation and light transmission; soaking the bulbs in potassium permanganate solution before planting can greatly reduce the incidence of rot; if the disease occurs, remove the affected part as soon as possible, dry the wound, and plant it in the pot again.

Replacement of brocade flower pests

Damage caused by Spodoptera litura

The larvae of the Spodoptera litura are voracious. They will eat leaf flesh, bite young flower buds, and chew on flower stalks and seeds. They can harm plants in all seasons except winter. The reproductive capacity of the Spodoptera litura is very strong, so they should be killed immediately once they are found.

Control methods for Spodoptera litura

The problem can be treated with a 2500-fold diluted Filipino suspension and a 1000-fold diluted Panacin.

Damage caused by Lycoris radiata moth

The larvae of the Lycoris radiata armyworm are relatively small and will directly invade the interior of the bulb, causing the bulb to become hollow and also hollowing out the leaves. In fact, this pest is quite easy to find, as green or brown feces pellets are usually left at the affected area. The eggs of the Lycoris radiata armyworm are light yellow in color and are usually laid on the back of the leaves. The eggs are arranged very neatly and should be removed immediately once discovered.

Methods for controlling the lycoris radiata moth

Loosening and turning the soil in winter and spring can identify overwintering insect pupae and reduce the insect population base. If larvae are found, they can be killed by spraying 1500 times diluted spray agent Lesi or 800 times diluted phoxim emulsifiable concentrate. The best spraying effect is in the morning or evening when the larvae come out to move around and feed.

Symptoms of damage caused by thrips in brocade

If the leaves suddenly turn green, you can check whether there are thrips at the leafing site of the hydrangea bulb. Thrips will cause the leaves to turn green after sucking nutrients.

Methods for controlling thrips in brocade

Once thrips are found, they can be controlled by rotating spraying with 3000-fold diluted imidacloprid and 8000-fold diluted Aimilo.

Damage caused by grubs in the brocade flower

Grubs will chew on the tender stems of young plants, and holes will be bored into the bulbs, eventually causing the entire plant to wither and die.

Methods for controlling brocade flower grubs

Pests can be killed by diluting 1000 times the amount of chlorpyrifos emulsifiable concentrate.
