Friends who often grow flowers should be no stranger to whitefly. Whitefly is a small flying yellow-and-white moth. The harm to flowers and plants is very serious.

Flower friends can choose 90% trichlorfon 800 murine 1000 times solution for leaf spraying, when spraying, pay attention to the back of the leaf should also be sprayed. It is carried out every other week, and the disease can be controlled in about a month.
Some flower friends live in the building, gardenia is planted on the balcony, not suitable for spraying. At this time, flower friends can use mosquito incense (a small method recommended by some flower friends), wrap gardenia flowers in a bag and light a mosquito incense to fumigate insects with mosquito incense. It will take about an hour to smoke. A few bug boards can be put on the daily balcony, which can reduce the damage of flying insects.
Daily attention should be paid to keeping the growing environment of Gardenia jasminoides ventilated and ventilated. More blowing can reduce the number of flying insects.
