Maize spot disease, also known as streak disease, coal wall disease, leaf disease, leaf spot disease. The main damage to corn leaves, leaf sheaths and temporal lobe. After the leaves became infected, water-stained gray-grey spots appeared first and then spread along the veins toward both ends to form large spots with dark brown, central hazel or blue-gray edges. Late lesions are often longitudinally divided. In severe cases the lesions fuse and the leaves turn yellow and die. There is a lot of gray moldy layer on the lesion when wet. The lower leaves first develop the disease. In the single-gene resistant varieties, the chlorotic lesions appeared. The lesions were small and parallel to the veins. The color was yellow-green or light brown and the surrounding dark brown. Some manifested as necrotic spots.
Control period and methods: Use 50% carbendazim or 25% triadimefon 1500g or 40% Fuxing (fluorosiliconazole) 37.5g per hectare at the end of corn leaf stage to heading stage or early stage of disease, and water 200kg, spraying Shi, once every 10 days, once against 2-3 times.
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
