What are the methods for preventing and controlling bitter melon (Momordica charantia) Fusarium wilt?

Bitter melon is a vegetable that is excellent for clearing heat and relieving summer heat, although it is also deeply loathed by quite a few people. Some even use bitter melon juice as a tool and method of punishment. But no one can deny the benefits of bitter melon. So as a must-have vegetable for the family, the market prospects for bitter melon are also very good. Accordingly, a large number of vegetable farmers grow bitter melon. But bitter melon is prone to a disease called Fusarium wilt. So how should bitter melon Fusarium wilt be prevented and controlled? Let's take a look together with the editor below~

1. The harm of bitter melon Fusarium wilt

Fusarium wilt is a very great threat during the growth of bitter melon, and the whole plant can develop the disease throughout the entire growth process.

1. Seedling stage

The resistance of bitter melon at the seedling stage is very poor. Some even rot in the soil before emerging. Even if they emerge, the leaves soon become wilted. The color begins to turn brown. Symptoms of water loss occur.

2. Adult plant stage

Although resistance is somewhat stronger at the adult plant stage, they can still get this disease. Generally the leaves wilt, and the melons become wilted. It is especially serious at midday. It recovers in the morning and evening. If left unchecked, rotting will occur, the lesions will become moldy, and they will appear reddish-brown. In severe cases, half the plant may wither, and the epidermis may peel off. Finally the whole plant dries up and dies.

2. Prevention and control of Fusarium wilt

The prevention and control of bitter melon Fusarium wilt can only be done well by combining scientific cultivation with chemical control.

1. Soil treatment. The soil will be exposed in the soil for 3 days to 5 days, so that the soil is fully exposed to white weathering, and the soil will reach 50~75 kg, thereby neutralizing soil acidity and inhibiting the growth of bacteria.

2. High ridges and deep furrows to prevent water accumulation. High temperature and humidity easily develop Fusarium wilt, so adopt the high-ridge and deep-furrow planting method to lower the groundwater level, prevent water accumulation after rain, and make the bed soil well aerated, which can reduce disease.

3. Cut off the leaves on the stems. When Fusarium wilt shows signs or has already occurred, promptly prune and remove the diseased branches and leaves. Also ventilate and dehumidify the field plants and furrows, thereby inhibiting the development and spread of pathogenic bacteria, and thus reducing the occurrence of disease.

4. Chemical control. When the disease begins to occur, remove the diseased plants. At the same time, spray 75% medicinal solution, 500 times to 800 times, 500 times to 600 times solution, 500 times to 800 times original powder. Spray once every 7 days, spray continuously for 10 days each time, 3 to 4 times a day. Note that spraying liquid on the lower half of the plant stems gives better results.

Alright, the above is how to prevent and control bitter melon Fusarium wilt brought to you by the Tuliu.com editor.
