It can be planted at home, it needs to prepare a soft and fertile maintenance substrate, the temperature needs to be controlled at about 25 ℃, sufficient light exposure, proper fertilization and so on.

Second, what are the key technical points for the prevention and control of common diseases and insect pests of towel gourd?

1. Loofah vine blight

Towel gourd vine blight is mainly harmful to stems and vines, but also to leaves and fruits. The disease spot on the stem is oval or fusiform, grayish brown, and sometimes the affected part overflows with amber glue, eventually causing the stem to die. Leaf disease, the edge of the leaf is semicircular or "V" shaped, brown or dark brown, slightly wheeled, the disease spot is often broken. The fruit disease spot is nearly round or irregular, the edge is brown, the middle is gray-white, and the flesh under the disease spot is mostly black dry rot.

2. Towel gourd downy mildew

The main harm to the leaves, the diseased leaves first appeared irregular light yellow to bright yellow disease spots, and then expanded into polygonal chloasma, the back of the disease spots appeared purple-black mold layer when it was wet, and the disease spots were connected into pieces in the later stage, the leaves withered and the yield was seriously reduced. Towel gourd downy mildew pathogen and cucumber downy mildew pathogen belong to the same pathogen, called Cuban pseudo-downy mildew fungus, the pathogen overwinters on the disease residue. Low temperature, overcast and rain, high air humidity, large temperature difference between day and night, and poor drainage in the field are all conducive to the disease. In the field, germs are spread by wind and rain. Downy mildew and powdery mildew frequently occur in the rainy season. 3000 times of 50% carbendazim wettable powder and 6000 times of 430g/L tebuconazole suspension are effective in controlling downy mildew.

3. Anthracnose of towel gourd

Towel gourd anthracnose is a fungal disease, the spot is nearly round, the diameter is different, about 2 cm. The color varies with temperature and humidity, dark brown when the temperature is high, light brown when the temperature is low and humidity is large.

Prevention and treatment: at the initial stage of the disease, spray 75% thiophanate wettable powder 700 times 800 times, 75% chlorothalonil wettable powder 700 times, or 50% carbendazim 1000 times 1500 times, or 80% anthrax Fumei wettable powder 800 times, or 65% benzoin zinc 500 times, or 50% carbendazim 800 times + 70% thiophanate 600 times Spray once at intervals of 7 to 10 days, and prevent and cure for 4 times in a row. It can also be sprayed with 25% anthrax 800 / 1000 times for 2 or 3 times in a row.

4. Towel gourd blight

It mainly harms the fruit, and sometimes the stems and leaves are also damaged. Most of the fruit disease starts from the flower pedicel, the disease spot is sunken, at the beginning of the water stain-like dark green when the humidity is high, the melon is very soft rot, and there are white mildew. In severe cases, it can infect leaves, stems and melon strips. The disease of stem vine is mainly in tender stem or Internode, which is watery at the beginning, wet rot and dark brown in the whole segment after expansion. Leaf disease, initially for water-stained yellow-brown spots, white mildew when humidity is high, bluish white when dry, easy to break. The pathogens are flagellate subphylum fungi and parasitic Phytophthora, which can be transmitted by hyphae or oospores on seeds and remnants.

Prevention and treatment methods: after the occurrence of the central diseased plant, spray 72% urea manganese zinc (KKangling) wettable powder 600x solution, or 72Kelu wettable powder 600x liquid, or 25% metalaxyl wettable powder 1000 times liquid, or 18% metalaxamide manganese zinc wettable powder 600x solution, or 70% ethyl phosphorus manganese zinc wettable powder 500x solution, about once every 7 days, prevention and treatment 2 times 3 times depending on the disease.
