    The appearance of fine white spider webs on plant leaves is mainly due to poor environmental ventilation, high temperature exposure, after watering the potting soil, because the water is slow to dissipate, the potting soil is not breathable, the potting soil is too wet, and the harm of insect pests, the feces discharged by the insect pests accelerate the infection of Baijuan bacteria.

    1. Check the root system.

    It is advisable to check the root system, if the base of the root has turned white and black, it means that this only needs to be disinfected and the soil has been changed.

    2. Prune. Seeing this, I suggest that we should focus on preserving the live, and recommend pruning, because the branches and leaves are very weak, so the waste of nutrients and water is very serious, and it is recommended to re-prune and cultivate new branches.

    3. Pesticide control.

    White silk disease is a bacterial disease, and after the outbreak can only be watered with bacterial drugs to prevent and control, and this pot of fragrant vine because of the outbreak of fungal diseases caused by insect pests, and then suffered from bacterial infection, so fungi and bacterial drugs should be prevented and controlled together.

    It is recommended to spray and water with copper thioxine and methyl tobuzin, and then pay attention to pest control.

    and other stinging and sucking pests. 4. Use a plate of lit mosquito coils, put them in the pots of diseased plants, and then tie them tightly with plastic bags, and after about an hour of smoke, they can be killed regardless of adult eggs or adult worms. It's a great way to save money and get quick results.

    The body of the spider mite is the size of a pinpoint, deep red or purplish-red, and only small red dots are visible to the naked eye, under a magnifying glass.

    The eggs are orange-red transparent balls. Its nymphs often swarm on the dorsal and bud of some flowers, and suck the sap with their stinging mouthparts. The initial symptoms of flowers are the loss of green leaves, the upward rolling of leaf margins, and even wilting and falling off, resulting in early atrophy of flower buds and the death of plants in severe cases.
