If the leaf miner's fly feeds on Primula Obconica, you need to spray 1000 times the latent gram, and you also need to improve ventilation management. DDVP can be sprayed to treat aphid pests.
The leaf miner can enter the leaf meat of primula obconica and feed on the leaves, which not only harms the health of the plant, but also reduces the ornamental value of the plant. The best precaution is to spray the diseased leaves with 1,000 times the amount of latent gram. At the same time, an enhanced ventilation environment and reasonable fertilization can increase the resistance of Primula Obconica.
Aphids are also one of life's most common pests, which can be prevented by the need to cool down and maintain a moist environment at their peak during periods of high temperature. If Primula obconica has this disease, it can be treated effectively by spraying DDVP every other week.
