Passion fruit contains a lot of nutrients needed by the human body. It is one of the fruits with the highest nutritional value and the most health-care function in the world. It is praised as the “king of juice”. However, in the process of planting passion fruit, farmers will encounter various pest and disease problems. This article summarizes the species and integrated control techniques of passion fruit pests and diseases in detail, and hopes to help farmers to do the planting work.

Types of pests and diseases of passion fruit

Disease type

The common diseases that endanger the growth of passion fruit are as follows: Let's elaborate on the following: The first type is called mosaic virus disease. When the passion fruit is replaced with this disease, the leaves of the passion fruit will show a flower-like shape. Light yellow spots appear on the leaves, and the leaves will wrinkle and shrink together. The fruits grown on the flowers will dry, shrink, deform, and the skin becomes stiff. Mosaic disease is generally more common in cold and dry seasons. The second type is called a fungal disease. When the seedlings of the flowers are damaged, the spots on the stems and leaves of the flowers will appear as water-stained spots. The spread of the lesions is very fast, and the leaves will soon fall off or directly cause the flowers. The plant died. Passion fruit is prone to such lesions in hot, humid weather. The third type is a fungal disease of stem-based rot. The disease is also water-stained in the early stage, and then the leaves gradually turn from green to brown. After extending 30-50 cm upwards, the stems and leaves gradually fade until they die.

2. Insect species

Different pests have different parts of the damage caused by the flowers. For example, citrus fruit fly, claw fly, and other insects endanger the fruit of Baihua Valley; coffee leopard scorpion moth damages the stem or main vine of the flowering fruit; red wax mites harm the side vine; cotton mites, citrus powder mites harm new Tips and leaves; red spiders harm the leaves. In addition, there are also aphids, thrips and other hazards that threaten the shoots and spread the virus.

Disease prevention method

Agricultural control methods for mosaic disease: First, choose the orchard where the passion fruit is grown. Do not choose the vegetable land where the melons and fruits have been planted, and do not choose the land where the fruits and vegetables have been planted nearby. Second, the cultivation of passion fruit is carried out using a virus-free planting technique. Third, it is necessary to strengthen the cultivation and management of passion fruit and improve the resistance of the passion fruit plant. Fourth, for some of the passion fruit plants that have been infected, it is necessary to remove the diseased leaves and diseased plants. The chemical control method can be sprayed with Bordeaux mixture of 0.5% to eliminate mosaic disease.

There are two ways to prevent and cure the disease. The first one is to make a strict selection of the planted passion fruit seedlings. The second method is the use of chemical control methods, which can be treated with 75 percent of chlorothalonil 800 times.

Stem-based rot prevention and control methods are mainly on the drainage. To avoid this disease, it is necessary to strengthen the drainage of the value points and orchards to avoid the roots being soaked and damaged.

2. Pest control methods

Agricultural control methods: Before planting passion fruit, we must first remove the weeds and some litter in the plantation, preferably by fire. Secondly, the soil in the plantation should be dug out for drying two months before planting, and lime can be used for disinfection and sterilization.

Chemical control method: 90% of the insect-resistant 800 times liquid and 1000 times of the agricultural land can be used to kill the insects.
