How to treat the white bug on hibiscus leaves?

The treatment methods of white moth on hibiscus leaves include spraying tobacco leaf water, liquor, washing powder water, chemicals, white vinegar and so on.

1, spraying tobacco leaf water.

If white flying insects are born on hibiscus flowers, spray a proper amount of smoke water. It is best to collect some cigarette butts in advance, then take out the cut tobacco from the cigarette butts, soak them in warm water for one day and one night, then take out the cut tobacco and spray it twice a week to eliminate white flying insects. If there are many pests on the leaves, cut them off in time and burn them.

Step 2 spray white wine

White flying insects may be whiteflies. During the treatment, spraying diluted liquor twice a week and four times in a row can eliminate whiteflies. In the later period of curing, we should pay attention to strengthening ventilation, ensuring good ambient light and suitable temperature, and hibiscus flowers will recover soon.

Step 3 spray washing powder water

Whitefly can be killed with washing powder water. Mix washing powder, urea and clear water according to the ratio of 1: 4: 400, then put them into a watering can and spray them on the leaves to kill whiteflies. Attention must be paid to ensure that both sides of the leaf surface are sprayed to completely eliminate the disease.

Step 4 spray chemicals

If there are many white flying insects on hibiscus flowers, it is necessary to spray chemicals to kill pests faster. The spraying of chemicals on hibiscus flowers planted in the open air will be resumed as soon as possible. Plants can be sprayed with 1000 or 1500 times malathion emulsion or 1000 times 10% omethoate emulsion to kill flying insects twice.

Step 5 apply white vinegar

First, take out the edible white vinegar at home, pour it into a 50 ml container, then soak the cotton swab in the white vinegar, and gently wipe the position where the hibiscus is infected with white flying insects with a wet cotton swab, so as to eliminate the white flying insects on the plant and avoid the subsequent infection of the plant.
