Latest Technical Methods Tutorial for the Prevention and Control of Pests and Diseases in Malabar Spinach

Malabar spinach is eaten as seedlings and tender shoots; its texture is tender, its taste is fragrant, crisp and refreshing, and its nutritional value is relatively high. It is well liked by people on the market and has good planting prospects. However, during cultivation, the harm caused by pests and diseases has become a major obstacle to growing Malabar spinach. So how should Malabar spinach pests and diseases be prevented and controlled? Let's take a look at the detailed introduction below.

1. Brown spot disease

Seedling fish-eye disease can cause damage from the seedling stage all the way to harvest. It mainly harms the leaf portion of the plant. When the disease occurs, purple-red water-soaked spots appear on the leaves and gradually expand. In severe cases, the lesions may merge into large spots, causing premature leaf aging and possibly even leading to plant death, with a huge impact on yield.

Prevention and control methods: rotate with crops that are not in the Chenopodiaceae family and not in the Basellaceae family, and soak the seeds in formalin for half an hour or less to eliminate pathogens carried by the seeds. When the disease occurs, spray with zineb once every 7-10 days, for 2-4 consecutive applications, and the control effect is excellent.

2. Gray mold

Gray mold generally occurs in the middle growth stage and mainly harms leaves and leaf stalks. When the disease occurs, lesions appear on the leaves, and in the later stage a gray mold layer appears on the lesions, which is also the origin of its name. In severe cases, it causes the leaves to rot and can also spread along the leaf stalks to the stems.

Prevention and control methods: strengthen fertilizer and water management, and pay attention to drainage during the rainy season to avoid water accumulation creating a suitable environment for pathogens and inducing this disease. When the disease occurs, benomyl or vinclozolin can be used, sprayed once every 10 days, for 2-3 consecutive applications, with good results.

3. Insect pests

Insect pests are mainly underground pests, which mainly harm the seedlings of the plant. The main pest is white grubs, which gnaw on the root system of the seedlings. In severe cases, they bite through the root system of the seedlings, causing the roots to lose their absorption capacity and the plant to gradually dry up and die.

Prevention and control methods: plow the soil in early winter to reduce overwintering insect sources. In addition, when sowing, phoxim can be spread into the soil to make poisonous soil for poisoning and killing, but attention should be paid to the concentration to avoid killing the seedlings.
